通过污泥自接种和污泥引种两种方式成功地进行了EM污泥培养与EM-SBR反应器启动试验.试验结果表明:连续投菌下启动污泥自接种EM-SBR反应器,COD平均去除率可达75.89%,与对照组相比,增幅为9.20%,且对进水COD浓度变化的适应稳定性明显增强;复合式投菌下启动污泥引种EM-SBR反应器,前阶段一次性投菌,反应器处理效果呈波浪式变化,与对照组相比无显著性差异,而后阶段连续投菌,反应器效果较对照组显著提高,COD平均去除率达81.10%,增幅12.47%,反应器稳定性明显改善;与自然污泥相比,EM污泥SV30、MLSS、SVI及其沉降速度均有一定程度的降低,污泥颗粒的凝聚、沉降性能及降解污水有机质活性均有明显改善和增强,...

The EM active sludge is cultured and EM-SBR reactor is started up successfully both by self-inoculation and with digested sludge as seed. The experimental results demonstrate that in the EM-SBR reactor started up by self-inoculation with continuous EM casting, the stable COD removal efficiency in effluent can reach about 75.89% and increases averagely about 9.20% than the routine reactor; that the stability of the reactor against the changes of influent COD concentration is remarkably boosted up; that in the reactor started up by using the digested sludge seed with multiplex EM casting, the tr...
