摘　　要：采用预处理一双膜系统组合工艺处理印染废水的达标排放水,处理后的产品水作为生产水回用。实际运行结果表明,出水中的浊度≤2 mg/L、CODc_r≤2 mg/L、pH=6.7~7.5、硬度≤3 mg/L、电导率≤50μs/cm,出水水质稳定达到该企业生产用水标准要求,从而节约大量新水,同时针对反渗透膜浓水进行处理,产生了良好的经济效益和环境效益。Using pre-treatment and double-membrane technology treated printing and dyeing wastewater of reaching the Standard and discharging, and reused in producing procedure. The practical result showed： turbidity≤2 mg/L, CODc_r≤2 mg/L, p H=6.7~7.5, hardness≤3 mg/L, Electrical conductivity≤50 us/cm. The effluent water quality achieves the water standard of reusing in printing and dyeing industry and the rejected water treatment is obtained. Thus saves a large amount of fresh water, and produces excellent economic and environmental benefits.
