摘要
采用氧化偶合絮凝法处理难降解的造纸废水 ,考察了各种因素对处理效果的影响。结果表明 ,在m(改性铝盐 ) m(改性钙盐 ) =2 1,总投加量 15 0mg L ,pH =7～ 8,反应时间为 2 0min条件下 ,COD去除率高达 85 % ,在最佳条件下处理效果高于硫酸铝、三氯化铁和PAC 。
The application of oxidation and flocculation process in papermaking wastewater treatment is studied. Factors affecting wastewater treatment results are investigated.The results show that the removal rate of COD is 85% when Al 3+ /Ca 2+ is 2, dosage is 150 mg/L, reaction time is 20 min, pH is 7～8. The treatment result of oxidation and flocculation compound agent are much better than those of Al 2(SO 4) 3, FeCl 3 and PAC. the water quality meets the wastewater standard.
