摘要
受服务范围内海藻加工企业生产废水混入的影响,中科成污水处理厂升级改造中COD的进一步去除成为难点。项目前期进行充分的研究分析,并开展现场中试研究,最终选择适合该厂水质特点的臭氧接触氧化-活性砂工艺。重点介绍了项目的工艺比选与改造效果,出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准。
By the influence of seaweed production wastewater, COD becomes difficult to remove in the advanced treatment of waste water. The activity sand filtration and ozone contact oxidation could upgrade the standard from the first level B to the first level A of Discharge standard of pollutants of municipal wastewater treatment plant (GB 18918-2002) through on-site test.
