接触氧化-人工快滤联合处理河道污染水体工程

Contact Oxidation Coupled with Artificial Rapid Filter to Treat River Pollution Water Engineering

对乌金河受污染河段上游进行截污,采用接触氧化-人工快滤联合进行处理,实际工程运行结果表明,在来水水质COD≤372mg/L,BOD≤153 mg/L,NH3-N≤15 mg/L,TP≤3.56 mg/L,SS≤94 mg/L情况下,出水水质可达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。系统运行稳定,可以对城市河流段污水进行治理,方法可行。

Made sewage interception for Wu Jin river upstream, and contact oxidation coupled with artificial rapid filter was applied for the treatment, the actual engineering operation showed that when the quality of inflow water was COD ≤ 372 mg/L, BOD≤ 153 mg/L, NH3-N≤ 15 mg/L, TP ≤ 3.56 mg/L, SS _〈 94 mg/I, quality of outlet water could reach the criteria of 《pollutants discharge standard of municipal wastewater treatment plants 》 which specified in GB 18918-2002. The system ran stably, it could carry through sewage treatment for the urban river section, and the method was feasible.
