The content of organic matter in aquaculture wastewater is particularly high, and the water quality of aquaculture wastewater changes greatly, so the treatment of aquaculture wastewater is more difficult.
In general, we often use cationic polyacrylamide and polyaluminum chloride to treat aquaculture wastewater, so that not only the effect is better but also save the cost of sewage treatment agents.
Through the molding experiment, using a specific type of polyacrylamide, specially for aquaculture sewage. Through simple flocculation sedimentation, most organic wastes in aquaculture wastewater can be removed and COD ammonia nitrogen in aquaculture wastewater can be greatly reduced. Through subsequent biochemical treatment of anaerobic, aeration and other processes, the discharge standard is basically reached. The water is clear, colorless and odorless, which mainly reduces the treatment cost and treatment time, which is a feasible treatment method for aquaculture wastewater.
