Abstract:

The biological degradabili ty of dyeing wastew ater is low.Therefore, it is hard to treat it by traditional biological process.It is found that using inorganic coagulant together wi th polymeric flocculant, WK-301, to treat this wastew ater has the following advantages the decolouration result is good ;the removal rate of organism is high ;the treatment expense is low ;and the operation is easy.The indexes of the outgoing water come up to the First Grade Discharge Standard.

Key words: dyeing waste water, coagulation sedimentation, decolouration, synergistic effect

摘要：

印染废水的生物降解性能较差,用传统的生物法处理难度大。通过试验发现以无机混凝剂与高分子脱色絮凝剂WK - 30 1复合使用,不仅脱色效果好、有机物去除率高、处理费用低,且使用简单,出水的各项指标均达到国家一级排放标准
