【摘要】 根据校园生活污水的污染程度低、重金属含量少、用水时间相对集中等特点,分别采用SBR法、SBR+厌氧法和用优势菌强化的SBR法对生活污水进行处理,比较了不同处理方法对COD去除率的影响。结果表明:在进水和出水条件相同时,优势菌强化的SBR法可缩短水处理的周期,处理后的水质达到国家排放的标准。更多还原

【Abstract】 The effects of different treatment methods on the wipeoff rate of COD were compared.According to the characters of lightly polluted,little heavy metal content and the convergence of wastewater output,the schoolyard domestic sewage respectively treated with SBR,SBR combined with anaerobic and SBR strengthened by superior strain.The result indicated:under the same conditions of wastewater discharge and intake,the period of wastewater treatment was curtailed with SBR strengthened by superior strain.The quality of the treated wastewater accord with the letoff standard.更多还原
