摘要
采用载体固体床为主要处理单元 ,辅以高效混凝剂处理中小型制革综合废水。工程运行表明 :在进水CODcr、SS、S2 -、总铬的平均浓度在 762mg/L、73 2mg/L、3 1mg/L、15mg/L的条件下 ,排水中的CODcr、SS、S2 -、总铬平均浓度为 192mg/L、95mg/L、0 .47mg/L、0 .8mg/L ,处理后的水质达到了GB8978- 1996《污水综合排放标准》
Carrier solid bed is used as the main treatment unit to treat effluent of medium-small size tannery supplemented by high efficient coagulant.Project indicates that the average concentrations of CODcr、SS、S 2-and tofal Cr of influent at 762mg/L、 732mg/L、 31mg/L and 15mg/L respectirely,the average effluent concentrations are 192 mg/L、95mg/L、0.47mg/L and 0.8mg/L. The water quality after treatment reaches Ⅱ grade standard of GB8978-1996 “Integrated wastewater discharge standard
