【摘要】 采用两级混凝沉淀作为PCB综合废水处理系统的物化处理工艺,在原水pH 1～5,总铜10～100 mg/L,COD 300～1000mg/L的条件下,出水水质稳定、可靠达到pH 7～8,总铜<0.3mg/L,COD <500mg/L,满足后续生化处理系统进水水质要求。更多还原

【Abstract】 Two-stage coagulation sedimentation is adopted as the physical and chemical treatment process of PCB integrated wastewater treatment system. Under the conditions of raw water pH 1 ～ 5, total copper 10 ～ 100 mg/L and COD 300 ～ 1000 mg/L, the effluent water quality is stable. Reliable to reach pH 7 ～ 8, total copper <0.3 mg/L, COD <500 mg/L, to meet the requirements of the subsequent biochemical treatment system influent water quality.更多还原
