摘要
根据校园生活污水的污染程度低,用水时间相对集中的特点,本试验采用以高效菌生物膜SBR法对校园生活污水进行处理,试验结果表明:最佳反应时间为 4 h,其 CODCr 和 NH4 - N 的去除率分别可达到 86. 1 %,94.7 %,处理效果明显好于普通活性污泥SBR法,且抗冲击负荷能力大大增强.处理后出水达到回用标准,用于绿化和清洁卫生,为校园生活污水处理提供了新思路.
In this experiment,the schoolyard domestic wastewater is treated with combination SBR strengthened by highefficiency strain biofilm according to the characters of lightly polluted and convergence of wastewater output.The result indicates:when optimum hydraulic residence time is 4 h,removal rates of COD_(Cr) and NH_4-N are seperately 86.1% and 94.7%,which is better than traditional SBR,and resistance to high volumetric organic loading is stronger. The quality of the treated wastewater accords with the reuse standard,and it can be used to irrigate and clean. Thus,the prominent efficiency of highefficiency strains on the schoolyard domestic wastewater treatment is presented.
