改良型SBR与V型滤池组合工艺处理市政污水

Combined Process of Modified SBR and V-type Filter for Treatment of Municipal Sewage

云南某市政污水厂一期工程规模为1.2×104m3/d,远期总规模为2.4×104m3/d。主体采用改良型SBR与V型滤池组合处理工艺。运行结果表明,在实际进水COD浓度为200～300 mg/L、TN浓度为25～40 mg/L、TP浓度为1.5～4.0 mg/L的情况下,处理出水各项指标均能稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。

The treatment capacity of the first-phase project of a municipal sewage treatment plant in Yunnan is 1.2 ^4m^3/d, and the total treatment capacity is 2.4 ^4m^3/d. The plant adopts modified SBR and V-type filter to treat the sewage. The practical operation showed that under the conditions of COD from 200 to 300 mg/L, TN from 25 to 40 mg/L and TP from 1.5 to 4.0 mg/L in the influent, the effluent quality met the first level A criteria specified pal Wastewater Treatment Plant （ GB 18918 -2002）. in the Discharge Standard of Pollutants for Munici-
