Cationic Polymer Wastewater Treatment
Cationic polymers are used in wastewater treatment
In today's world, the suffering of wastewater is related to people's livelihood and ecology, and is of great importance to everyone. To solve this problem, cationic polymers are gradually showing their effectiveness in wastewater treatment.
Cationic polymers, with their unique chemical structure, have many wonders. The cationic groups in their molecules, together with the negatively charged suspended particles and colloids in wastewater, can generate electrostatic attraction. This force is like magnets attracting each other, causing the particles to approach each other, and then agglomerate, from a scattered state to a larger aggregate.
It is effective in industrial wastewater treatment. Industrial wastewater has a variety of components, including heavy metal ions, organic pollutants, etc. The cationic polymer is put into it, first by the attractive force of electrostatic electricity, the fine pollutants are gathered in one place. Then, its long chain structure can play a bridging role, like a rope, so that more aggregates are entangled with each other to form larger flocs. This flocs precipitate rapidly and can be effectively separated from wastewater to clarify the water quality.
Domestic wastewater treatment, cationic polymers can also be seen. Domestic wastewater is rich in proteins, oils, cellulose and other organic matter, causing the water body to be turbid and eutrophication. Cationic polymer input first breaks its colloidal stability, so that the suspended matter coagulates and settles. And it can absorb organic molecules dissolved in water, further purify water, reduce its chemical oxygen demand and biochemical oxygen demand, so that the treated water can meet discharge standards, or be reused for greening, toilet flushing, etc., and the effect of water saving is also obvious.
However, the use of cationic polymers in wastewater treatment also requires caution. The amount of its dosage is related to the treatment effect. If the amount used is small, the agglomeration will not be sufficient, and the wastewater will be difficult to clean; if the amount is large, not only will the cost increase, but also the water quality may be polluted again. Therefore, in actual operation, it is necessary to accurately measure and find the best dosage according to the characteristics of wastewater.
In short, cationic polymers are a powerful method for wastewater treatment. With the advance of technology, its performance may be optimized, and its application will be more extensive and in-depth, contributing to the protection of water and the beauty of ecology.
