通过对某印染废水处理站的现场实际调研，总结问题，进行了以“生化+臭氧+反渗透”为主的中试研究。结果表明：在采用该工艺的条件下，系统出水稳定，COD和色度的去除率均达到95%以上；回收率为50%的情况下，反渗透出水完全可以满足生产回用要求，同时反渗透浓水还可以达到当地排放标准。

Based on the on-site practical survey of a printing and dyeing wastewater treatment station ,the problems have been summarized,and the pilot-scale test focusing on “biochemistry+ozone+RO”has been conducted. The re-sults show that under the process conditions ,the effluent from the system is steady. Both of the removing rates of COD and chroma can reach 95%. When the recovery rate is 50%,the RO effluent can completely meet the recycle requirements for the production. In addition,the RO concentrate can also meet the local discharge standard.
