摘 要: | 采用高效微生物菌剂结合传统SBR法处理校园生活污水,考察微生物菌剂对污水处理和污泥减量效果。结果表明:在相同反应条件下,投加混合菌剂的SBR系统对污水的处理和污泥减量效果,好于投加FM菌剂的SBR系统和传统SBR系统。与传统SBR法相比,投加高效微生物菌剂能够在降低SBR污泥浓度的同时,有效地保证污水处理效果。混合菌SBR处理校园生活污水对CODCr、NH3-N、TP的平均去除率分别为92.5%、78.7%、66.5%,污泥减量6%,出水CODCr、NH3-N、TP质量浓度达到GB 18918—2002《城镇污水处理厂污染物排放标准》二级标准。

Abstract: | A novel technology that combine high-efficient microbial agent with traditional SBR process was used to treat schoolyard domestic sewage, the influences of different microbial agents on treatment effect and sludge reduction were investigated. The results showed that: under the same reaction condition, the effect of sewage treatment and sludge reduction by the SBR added with mixed microbial agents was better than that by the SBR added with FM microbial agent or traditional SBR. Compared with traditional SBR, the SBR added with high-efficient microbial agent could reduce sludge concentration and ensure a good treatment effect on wastewater at the same time. Using the SBR added with mixed microbial agents to treat schoolyard domestic sewage, the average removal rates of CODcr, NH3-N and TP were 92.5%, 78.7% and 66.5% respectively, the sludge reduction rate was 6%, the mass concentrations of CODc,, NH3-N and TP in the effluent water met the specification for grade 2 in GB 18918--2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. |
