纳滤膜法与臭氧化法结合处理织染工业废水

Combination of nanofiltration and ozonation to treated textile wastewater for its reuse in the industry

目前织染工业排出的污水一般经活性污泥作用被中和后排放,这种废水处理厂排放出的水因其残余COD,电导率较高仍不适于再利用。通过把重心集中在用纳膜技术与化学氧化法相结合处理经活性污泥处理后的织染废水,筛选出合适的纳滤膜,并对工艺流程及操作条件进行探讨。

It focuses on the advanced treatment of the wastewater for a textile plant. Nowadays the factory effluent is treated by an activated sludge process carried out after the wastewater neutralization. The wastewater treatment plant effluent is not still appropriate for its reuse because of the residual COD and conductivity. Both nanofiltration experiments in different operating conditions and oxidation reactions with ozone and ozone/UV irradiation are adopted to evaluate the final water quality for its reuse.
