How to deal with the outbreak of organic phosphorus in pesticide synthesis wastewater?
Thread Content
Let’s start with the company’s treatment process: pretreatment + anaerobic filter + activated sludge tank + CAPT tank. The parameter of total phosphorus was not present in the wastewater before; recently, the wastewater from the workshop has contained large amounts of organic phosphorus, resulting in a level of organic phosphorus in the effluent of 20 mg/L. It’s far above the limit. . . How should it be handled? The wastewater before was free of phosphorus-containing wastewater. . .
What is the level of organic phosphorus in the incoming water? The challenge in treating organic phosphorus lies in its composition – specifically, whether it refers to organic phosphorus compounds that are difficult to oxidize into phosphates. Approximately 50% of organic phosphorus can be removed using biochemical systems; after that, the use of strong oxidants along with flocculants can further help remove organic phosphorus
