工业废水的脱色方法研究与应用展望

Progress in Studies on Decolorization of Industrial Wastewater

工业废水中的印染废水和焦化废水,由于废水量大、成分复杂、色度高,一直以来是水处理的难点之一,这两种废水含有类似的显色基团,对环境危害大,甚至还有致畸致癌作用,如何将含有这些显色基团的物质从废水中分离是近年来研究的重点之一,本文综述了吸附脱色法和絮凝脱色法在印染废水和焦化废水中的研究,对近年来国内外的研究成果进行了介绍,并对今后工业废水脱色处理进一步研究的问题提出了建议。

Treatment of dyeing wastewater and coking wastewater, with complex components and high color , is one of themost difficult part in industrial wastewater treatment field. Dyeing wastewater and eoking wastewater contain similar colorcontaminants, which are harmful to the environment and human health, sometimes they can even have teratogenic andcarcinogenic effects. In recent years, removal of color contaminants from wastewater is a hot issue in wastewater treatmentresearch area. This paper reviews the recent researches on decolorization applied in dyeing wastewater and cokingwastewater treatments, which provides an overview of latest research processes at home and abroad, and gives suggestionsfor further study of industrial wastewater decolorization treatment in the future.
