摘要
染料废水具有"三高一低"的特点(高COD、高色度、高含盐量、低BOD5/COD),是废水治理的难点热点之一。本文采用混凝、气浮、厌氧水解酸化、好氧和去反色工艺处理了染料废水,通过小试和中试试验发现该工艺具有实用性、合理性和先进性,出水达到纺织染整工业污染物排放标准(GB 4287-92)。
Dye wastewater treatment is one of the some focuses and difficult points,which have the following characteristics： higher concentration COD,chroma salt and lower biodegrade-ability.In this paper,coagulation,air flotation,anaerobic hydrolysis-acidification,oxic and removing reverse color were adopted to treat the dye wastewater.According to laboratory scale and pilot scale tests,the process is very practical,reasonableness and advanced.The effluent water can meet the Standard（GB 4287-92） of discharge standard of water pollutants for dyeing and finishing of textile industry.
