芬顿氧化-混凝深度处理二级出水试验研究

为了解决污水处理厂二级出水中有机物、总磷(TP)等污染物的超标问题,采用芬顿氧化-混凝工艺对污水进行深度处理,通过正交试验和单因素试验探讨了该工艺对污水的处理效果。研究表明:在芬顿氧化反应时间为40min,初始pH值为6.0,FeSO_4·7H_2O和H_2O_2投加量(质量浓度)分别为600mg/L和850mg/L,且混凝反应pH值为8.0,阴离子聚丙烯酰胺(APAM)投加量(质量浓度)为3.0mg/L的最优反应条件下,出水化学需氧量(COD)、色度和TP的去除率分别为97.5%,96.7%和99.2%,且均达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准。该工艺...

water pollution control engineering; Fenton oxidation; coagulation; secondary effluent; advanced treatment
In order to solve the problem of having excessive organics, total phosphorus(TP) and other pollutants in secondary effluent from municipal wastewater treatment plant, Fenton oxidation-coagulation unit is adopted to treat the wastewater. The treatment efficiency of the treatment process is discussed through the orthogonal experiments and the single factor experiments. It shows that the removal efficiency of COD, colority and TP are 97.5%, 96.7% and 99.2% respectively under the
