Case Studies on Wastewater Treatment at Livestock Farms

Pollution Issues: COD, ammonia nitrogen, total phosphorus, organic sludge

Wastewater Issues: Aquaculture farms discharge large volumes of wastewater daily with a heavy pollution load, high concentrations of organic matter, and a mixture of solids and liquids. If discharged into the environment or used directly for domestic purposes without treatment, it will cause severe pollution to the ecological environment and farmland. Due to the high organic matter content, the wastewater is generally acidic.

Solution: Polyacrylamide used for wastewater treatment at aquaculture farms must possess excellent flocculation, dewatering, adsorption, and stability properties. Cationic polyacrylamide is used to first flocculate the wastewater sludge, after which the flocculated sludge enters dewatering equipment for dewatering.

Treatment Results: This process ensures compliance with wastewater discharge standards.
