【摘要】 利用SBR反应器,探讨了XLG型生物工程菌Bacta-Pur~对城市污水的处理效果。试验结果表明:投加工程菌后,其对COD和TP的最高去除率可分别达到94.51%和79.43%,但对NH3-N的去除率较低。处理后出水的COD和TP均可满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级B标准。关键词:污水处理;工程菌Bacta-Pur;SBR反应器更多还原

【Abstract】 The treatment effect of municipal wastewater by engineering bacteria Bacta-Pur XLG was investigated using SBR reactor.The results show that after dosing Bacta-Pur XLG into the reactor,the removal rates of COD and TP reach 94.51% and 79.43% respectively,but NH3-N removal rate remains relatively low.The COD and TP in the treated effluent can reach theⅠ-B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).更多还原
