摘　　要：为研究华东地区印染企业废水中总铬和六价铬的污染现状及其来源,调查了21家印染企业并对其废水进行取样测试。结果表明废水中检出的总铬和六价铬浓度范围分别是0~425μg/L和0~66μg/L,污染程度总铬高于六价铬。废水中总铬或六价铬污染的主要来源是染料、颜料、印花油墨、含铬试剂、印花滚筒雕刻试剂和生产用新鲜水。In order to study the pollution status and sources of total chromium and hexavalent chromium in the wastewater of printing and dyeing enterprises in East China,21 printing and dyeing enterprises were investigated and their wastewater samples were tested.The results indicate that the concentration range of total chromium and hexavalent chromium detected in wastewater is 0~425μg/L and 0~66μg/L respectively,and the pollution status of total chromium is more serious than that of hexavalent chromium.The main sources of chromium pollution in wastewater are dyes,pigments,printing ink,chromium reagents,printing cylinder engraving reagent and incoming water.
