Method for comprehensively treating sewage of chemical fiber oiling agents in production plants

The invention discloses a method for comprehensively treating sewage of chemical fiber oiling agents in production plants. The method mainly includes the following steps: mineral oil is recovered from the chemical fiber oiling agents through acidification; the acidified lower clear liquid is performed with a Fenton reaction and then enters a middle water tank to be homogenized with washing water in a workshop and run-off rain water of oiliness paths; suspended materials and small elaioplast in the homogenized sewage are removed through an air floating pool; the water discharged from the air floating pool and sanitary sewage together enter a comprehensive adjusting tank to be treated by an anaerobic baffle pool, an aerobiotic pool and a settling pool, and then outlet water can meet the B-level wastewater quality standards for discharge to municipal sewers (CJ3082-2010). The method for comprehensively treating sewage of chemical fiber oiling agents is convenient to manage and maintain, capable of adapting to large water quality fluctuation, stable and reliable in treating effect and moderate in operation cost.
