摘要:
针对含三乙胺等难生物降解、微生物生长抑制性的催化剂生产废水，分别采用传统活性污泥法、芬顿氧化+活性污泥法和高效生物菌制活性污泥法三种工艺进行处理。结果表明，传统活性污泥法污染物去除率较低，不能达标排放；采用芬顿氧化预处理工艺和投加高效生物菌剂都能取得很好的去除效果。实际工程采用水解酸化池+MBR作为主体处理工艺，生化池中投加高效生物菌剂，普通污泥及高效生物菌剂投加比例为4 ∶1，运行实践表明，出水水质满足天津市《污水综合排放标准》(DB 12/356—2008)的三级标准。该工艺运行稳定，相比于芬顿氧化结合传统活性污泥法，可极大简化工艺流程，节省占地，产泥量少，运行费用低。
Abstract:
In view of catalysts production wastewater that are difficult to biodegrade and inhibit microbial growth due to triethylamine and etc., the traditional activated sludge process, Fenton oxidation with activated sludge process, and high-efficiency biological bacterial activated sludge process were used separately. It was showed that the traditional activated sludge method had a low removal rate and could not meet the discharge standard. While the Fenton oxidation pretreatment process and high-efficiency biological bacteria could achieve good removal results. The main treatment process was hydrolyzed acidification tank and MBR in the project, and biochemical tank was added with high-efficiency bacteria. The ratio of ordinary sludge and high-efficiency bacteria was 4 ∶1. The operation practice showed that the effluent quality met the third level criteria in the Integrated Wastewater Discharge Standard (DB 12/356-2008). The process ran steadily. Compared with Fenton oxidation combined with traditional activated sludge method, the process could greatly simplify the process route, save land occupation, produce less sludge and had low operating cost.
