Water Treatment Agent for Papermaking Waste Water in China
On the water treatment agent of Huaxia papermaking wastewater
Huaxia papermaking industry is thriving, but the principle of wastewater is related to environmental protection and the sustainability of the industry, which is of paramount importance. Water treatment agents are crucial in papermaking wastewater.
Papermaking wastewater contains various pollutants, such as fibers, fillers, chemicals, etc., with deep color, high turbidity, and abundant organic pollutants. The choice and use of water treatment agents depends on the characteristics of wastewater.
Flocculants are common in papermaking wastewater treatment. They can make suspended particles in wastewater gather and settle, and the effect of removing turbidity is obvious. In Huaxia, the research and use of flocculants have advanced. Inorganic flocculants such as polyaluminum chloride are widely used because of their high efficiency and low price. Organic polymer flocculants, such as polyacrylamide, have strong bridging adsorption energy and can increase flocculation effect. The combination of the two often results in better sedimentation and impurity removal.
Oxidation-type water treatment agent is also important. It can break the structure of organic pollutants in wastewater and reduce its chemical oxygen demand (COD). Such as chlorine dioxide, hydrogen peroxide, etc., it degrades organic pollutants in papermaking wastewater quite well. And chlorine dioxide has strong disinfection power, can kill bacteria and algae in water, and reduce the damage to the ring.
Adsorption-type water treatment agent can absorb pollutants in wastewater with its large specific surface area. Activated carbon is typical and has excellent adsorption of color, odor and some organic pollutants. Clay adsorbents, such as bentonite, after modification, increase adsorption capacity, and are cheap and easy to obtain, and are also used in some paper enterprises in China.
However, there are still challenges in the research and application of papermaking wastewater treatment agents in China today. The research and development of new high-efficiency water treatment agents needs to be advanced, and some high-end products rely on imports. And the application process of water treatment agents needs to be more scientifically optimized to reduce costs and improve efficiency.
To sum up, in order to promote the development of China's paper industry, the beauty of protecting the ring, and the research, production and use of water treatment agents should continue. Explore new high-efficiency agents, make good use of the process, and achieve proper treatment of papermaking wastewater, so as to promote the harmonious coexistence of industry and the ring.
