摘要

在实验室对集装箱喷漆废水处理工艺及主要参数进行了研究。结果表明,采用SBR生化降解-物化混凝处理喷漆废水在技术上完全可行。采用SBR法处理喷漆废水时,喷漆废水与生活污水按6∶4左右的比例混合,使进水COD控制在1400~1600mg/L。在此条件下,经过24h的生物好氧处理,能将出水的COD降至150mg/L以下。之后,再投加混凝剂〔V(聚铝)∶V(聚丙烯酰胺)=2∶1〕进行混凝处理,可进一步将出水COD降到80mg/L以下,达到国家二级排放标准。

Abstract

A lab-scale experiment has been conducted to study the suitable process and the key operational parameters of spraying paint wastewater treatment of containers.It is concluded that,spraying paint wastewater treatment by the combination of SBR system and physico-chemical coagulation is feasible to meet the related environmental standards.In the SBR system,the proportion of spraying paint wastewater and the domestic wastewater should be about 6∶4.the influent COD should be controlled between 1400-1 600mg/L.Under such conditions,the effluent COD can be decreased below 150mg/L and SS below 200mg/L by a aerobic biological treatment.Following coagulation with PAC and PAM (2:1volume ratio),SS can be decreased below 50mg/L,reaching chinese related effluent standard.
