Treatment of Washing Water by Co-coagulation Flotation-Biological Contact Oxidation-Activated Carbon Column Process

摘要：

　　The article researched co-coagulation flotation-biological contact oxidation-activated carbon column process to remove COD,NH4+-N,TP and SS in washing wastewater.Experimental results showed in the co-coagulation flotation the removal of COD,NH4+-N,TP and SS were 57%,42%,37% and 86%,respectively.In biological contact oxidation treatment,the purification degree of waste water observably improved and the removal rates of COD,NHa+-N and TP were 85%,65% and 63%,respectively.The final removal efficiencies of COD,NH4+-N and TP were 90%,72% and 70% in the activated carbon column.The finial effluent ensures national standards.
