摘　　要：纺织业轻洗工段中的洗衣废水中含有柔软剂等有机物以及少量盐分,排放后会对水体造成污染。本实验通过微氧水解-好氧膜生物反应器和纳滤系统对洗衣废水进行处理,废水pH为7.46,浊度为224 NTU,COD为845 mg/L,电导率为912μS/cm,经过该系统处理后,出水pH为6.4,浊度几乎为0 NTU,COD为10 mg/L,电导率为70μS/cm,达到了洗衣工艺对水质的要求。The main pollutants in washing wastewater from textile factory are organic substance such as softing agent and few salts, which can pollute the water body. The technology of hydrolyzation-MBR and NF was used to treat the washing wastewater. The pH,turbidity, COD and conductivity of the wastewater were 7.46,224 degree,845 mg/L and 912 uS/cm respectively, after treatment, the values were 6.4,0 degree, 10 mg/L and 70uS/cm respectively. The quality of the wastewater treated by the process can meet the requirement in quality of the washing water.
