摘要
Abstract
This paper used compound flocculation technology-oxidation-the combination of ul-trafiltration method for the treatment of papermaking wastewater. The first compound flocculation determined the optimum process conditions: PAC-PFS-CPAM = 5 : 2 : 2 (the volume ratio) , the pH of 6. 8, take clear liquid for determination, wastcwater COD index from 102 984 mg · L-1 was reduced to 982 mg · L-1 ; then the 10% of ammonium persulfate oxidation process ,the COD index was reduced to 347 mg · L-1 ; Finally the self-regulating ul-trafiltration membrane centrifuge process, wastewater COD index was dropped to 86 mg · L-1.关键词
