Historical Development
Papermaking wastewater treatment agent, through the ages, its development process has been quite tortuous. In the past, papermaking was just emerging, and wastewater treatment was not paid much attention, so there was no special agent for this agent. And the industry gradually flourished, and the suffering of wastewater became more and more obvious, so craftsmen began to pay attention. At the beginning, I tried all kinds of materials, but the results were unsuccessful.
After several generations of research, it gradually gained some results. Some are improved by natural things, and some are synthesized by chemical methods. From simple formula to fine process, its performance is improving day by day. From a single effect to a variety of effects, it can not only settle impurities, but also remove color and deodorize. The evolution of this agent depends on the unremitting efforts of researchers of successive generations, and it has now become prosperous. It has made great efforts for the treatment of papermaking wastewater.

What are the main components of papermaking wastewater treatment agent?
The main components of the water treatment plant of a paper mill are mostly related to a variety of chemicals and natural substances.
Let's talk about the flocculant first, which is one of the key components. The flocculant can make the suspended particles in the water gather together to form larger flocs, which is convenient for sedimentation and separation. Common flocculants are polyaluminum chloride, polyacrylamide, etc. Polyaluminum chloride can produce polynuclear hydroxyl complexes through hydrolysis, adsorb and bridge particles, so that the particles agglomerate; polyacrylamide, with its long-chain polymer structure, exerts the effect of adsorption and flocculation, accelerates the sedimentation of particles, and reduces the turbidity of the water.
Furthermore, it is a neutralizing agent. During the papermaking process, wastewater may be acidic or alkaline, and it needs to be adjusted with a neutralizing agent to make its pH reach an appropriate range. If the wastewater is acidic, it is often neutralized with alkaline substances such as lime and sodium hydroxide; if it is alkaline, acidic substances such as sulfuric acid and hydrochloric acid are used. Taking lime as an example, it reacts with acid to generate calcium salts and water, which effectively adjusts the pH of wastewater and creates good conditions for subsequent treatment.
In addition, there are coagulants. Coagulants can assist flocculants to achieve better results. For example, activated silicic acid can enhance the structural strength and settlement performance of flocculants, making the flocculation process more efficient. It can synergistically interact with flocculants to make the formed flocculants tighter and coarser, thereby accelerating precipitation and improving water treatment efficiency.
At the same time, water also contains natural components, such as microorganisms. In a specific treatment stage, beneficial microorganisms can decompose organic pollutants in water and convert them into harmless substances such as carbon dioxide and water. Anaerobic microorganisms can decompose complex organic matter in an anaerobic environment to generate gases such as methane; aerobic microorganisms can completely oxidize and decompose organic matter under aerobic conditions to purify water quality.
There are precipitated impurities. Papermaking wastewater often contains suspended impurities such as fibers and fillers. After flocculation and sedimentation, these impurities settle at the bottom and separate from water, thereby reducing the solid content in the water and improving the clarity of the water, so that the treated water can meet discharge standards or reuse requirements.

What are the scope of application of papermaking wastewater treatment agents?
The scope of application of the wastewater treatment device in a paper mill is related to many aspects.
It can be applied to all kinds of wastewater treatment in the papermaking process. Pulping wastewater, which is the first stage wastewater of papermaking, is rich in a large amount of fibers, lignin and other organic matter. The sewage treatment device can effectively separate fibers, degrade lignin and organic matter, and make it meet the discharge standard. Pulp washing wastewater, which has complex components such as fibers and black liquor, can be removed by multiple processes such as precipitation and filtration to remove impurities and pollutants and purify the water body. Paper machine white water, although slightly less polluted, contains fine fibers and chemical additives. The device can also treat it to achieve water recycling and save water resources.
From the perspective of scale, whether it is a large papermaking enterprise with a huge daily wastewater discharge, or a small and medium-sized papermaking mill with a relatively small daily wastewater output, this wastewater treatment device can be adapted. Large enterprises have high wastewater treatment requirements, and the device can adopt large-scale and efficient treatment processes and equipment to cope with a large number of wastewater treatment tasks; small and medium-sized enterprises can choose relatively small and flexible devices according to their own output and site conditions to meet the discharge standards.
Furthermore, in terms of the regional environment, in places where water resources are scarce, the wastewater treatment device of the paper mill not only realizes the discharge standard, but also focuses on the reuse of water. The treated water can be reused in some aspects of the papermaking process to reduce dependence on fresh water resources; in areas with strict environmental protection requirements, the device must have more refined treatment capabilities to ensure that the pollutant indicators are far below the national standards and protect the local ecological environment.
In summary, the wastewater treatment device of the paper mill has a wide range of applications, from wastewater from different papermaking processes, to paper mills of various sizes, to different regional environmental needs, which can effectively respond, providing strong support for the sustainable development of the paper industry.

How to measure the treatment effect of papermaking wastewater treatment agent
The effectiveness of wastewater treatment in paper mills, the method of testing, is related to the purity of water and the tranquility of the environment, and it is a real priority. To know the geometry of its test effect, you can observe it from the following ends.
The first view of the water color, the treated water should be clear and clear, free of turbidity and filth. The water that was not treated in the past was as colored as ink, and the turbidity could not be seen, as if it were a stain. If properly treated, the water should be like a clear spring, colorless and transparent, and you can know its purity when you look at it.
The second smell of water, the water after treatment, when there is no odor. When it is not treated, the stench of wastewater is pungent, and you can still smell it from a hundred steps away, which is disgusting. If the treatment is successful, the water should be odorless, or only have a slight clear taste, such as spring rain moisturizing the soil, fresh and natural.
Measure the water quality again, such as pH, chemical oxygen demand, biological oxygen demand, etc. Before treatment, the acid and alkali of wastewater are unbalanced, and the chemical oxygen demand and biological oxygen demand are extremely high, far exceeding the appropriate standard. This is because the papermaking materials and agents are mixed in the water. After treatment, the pH should be close to neutral, and the chemical oxygen demand and biological oxygen demand will be greatly reduced, approaching the number of natural water bodies. This is a sign of meeting the standard.
Looking at the sundries in the water, the water after treatment should not have fibers, debris and other papermaking residues. In the past, wastewater, fibers were vertical and horizontal, and debris floated, just like garbage. If the treatment is effective now, the water should be clean and free of residue.
And observe its impact on the environment. After treatment, the water is discharged in the surrounding area, the surrounding soil should not be compacted, the surrounding grass should not be yellow, and the surrounding water should not change color. If so, it proves that the wastewater is harmless to the environment after proper treatment.
In this way, from the water color, water taste, water quality, water debris and the impact on the environment, we can know the effectiveness of paper mill wastewater treatment.

What is the use of papermaking wastewater treatment agent?
The method of water treatment in a paper mill is quite exquisite. First, water needs to be collected in a pool. This pool is the first to settle, and the water enters it, and the sundries settle. Sand, gravel, mud, etc. gradually settle at the bottom, while the water is slightly clear.
Then, lead the water to the reaction tank. The pool is filled with a medicine, such as alum. Alum is dissolved into water, and its quality can make the dust in the water gather. The dust is accumulated and gradually forms a flocculation, which is the appearance of flocculation. The flocculent gradually settles, and the water is cleared again.
After that, the water passes through the filter. This device is either made of sand or charcoal. Sand can filter its large grains, and charcoal can absorb odors and pigments. The water is absorbed by the sand filter carbon, with fewer impurities, and the color and taste are also good.
However, the water is still not clean, and it still contains bacteria. Therefore, it is necessary to add disinfectants, such as chlorine gas, chlorine dioxide and the like. The agent is mixed with water to kill bacteria in water. At this point, the water can reach the discharge standard.
When operating, all parameters need to be accurate. The amount of the agent varies depending on the water quality; when it is precipitated, the length is fixed; the speed of filtration also needs to be appropriate. And it is necessary to constantly check the water quality and adjust the method according to its changes. In this way, good effects can be obtained, so that the sewage of papermaking can be turned into usable water, which not only complies with environmental protection regulations, but also saves resources and increases efficiency. It is very important in the papermaking industry.

What is the impact of papermaking wastewater treatment agents on the environment?
The water treatment area of a paper mill is related to the ecology of a party's water and soil, and has a profound impact on the environment.
If its wastewater is discharged without proper treatment, the first to bear the brunt is the water body. Water is the source of life, and papermaking wastewater is rich in many harmful substances, such as fibers and chemicals. The accumulation of a large amount of fibers can cause the water body to be turbid, the light transmission will be greatly reduced, and it will be difficult for plants in the water to perform normal photosynthesis, which will then affect the energy flow of the entire water ecosystem. The heavy metals, acid and alkali substances contained in the chemicals may change the pH of the water body, or enrich the heavy metals in aquatic organisms. The living environment of aquatic organisms such as fish has deteriorated, or a large number of deaths have been caused, and the water ecological balance has been seriously damaged.
Furthermore, the soil is also affected by it. Sewage seeps into the soil through surface runoff, which will change soil properties. Soil pores are blocked, ventilation and water permeability become poor, and fertility decreases, affecting the growth of crops and vegetation. If the surrounding farmland is irrigated by this sewage for a long time, the quality of crops will decrease and the yield will also decrease.
Not only that, but the atmospheric environment is also affected. The foul smell emitted by papermaking wastewater contains hydrogen sulfide, ammonia and other harmful gases, which are dispersed with the wind, pollute the surrounding air, greatly reduce the quality of residents' living environment, and pose a threat to human respiratory tract and other health.
However, if the water treatment department of the paper mill can adhere to the scientific method, strictly treat the sewage, and discharge it after meeting the discharge standards, the negative impact on the environment can be greatly reduced. Through precipitation, filtration, biological treatment and many other processes, most of the harmful substances in the sewage can be removed, and it can be converted into cleaner water and returned to nature. In this way, a balance can be found between the development of the paper industry and environmental protection, and a sustainable development path can be achieved.
If its wastewater is discharged without proper treatment, the first to bear the brunt is the water body. Water is the source of life, and papermaking wastewater is rich in many harmful substances, such as fibers and chemicals. The accumulation of a large amount of fibers can cause the water body to be turbid, the light transmission will be greatly reduced, and it will be difficult for plants in the water to perform normal photosynthesis, which will then affect the energy flow of the entire water ecosystem. The heavy metals, acid and alkali substances contained in the chemicals may change the pH of the water body, or enrich the heavy metals in aquatic organisms. The living environment of aquatic organisms such as fish has deteriorated, or a large number of deaths have been caused, and the water ecological balance has been seriously damaged.
Furthermore, the soil is also affected by it. Sewage seeps into the soil through surface runoff, which will change soil properties. Soil pores are blocked, ventilation and water permeability become poor, and fertility decreases, affecting the growth of crops and vegetation. If the surrounding farmland is irrigated by this sewage for a long time, the quality of crops will decrease and the yield will also decrease.
