Abstract:
Provided is a method of treating wastewater and recovering resources in acrylic fiber production, comprising the following steps: 1) filtering wastewater from water-washing and filtering unit of acrylic fiber plants by a filter to intercept and recover high-molecular-weight polymer contained therein, and then making the recovered polymer returned back to the acrylic fiber production and entered the finished product, optionally, reusing part of filtered wastewater as low salinity water in the water-washing and filtering unit; 2) removing non-interceptable high-molecular-weight polymer in the wastewater by subjecting the wastewater to coagulation and air floatation treatment; 3) introducing the effluent into biological treatment unit and adding polyvalent metal ions as an adsorption promoter to increase the removal of the non-biodegradable organics in the biological treatment unit; and 4) removing the organics remained in the effluent from the biological treatment unit by an advanced treatment.

Claim (Index 6):
The method according to  claim 5 , wherein the coagulant is poly aluminum chloride or poly aluminum ferrous chloride, and the amount added is 50 to 200 mg/L; the coagulant aid is polyacrylamide, and the amount added is 2 to 10 mg/L; the reflux ratio of the air-saturated water is 30% to 60%; and the COD removal rate is 10% to 20%.
