| 摘 要： | 通过小试研究了滤池反冲洗废水直接回流利用对出水水质的影响.结果表明,反冲洗废水的直接回流利用对混凝过程有较为明显的强化作用,能够降低出水浊度和残余铝含量;当回流比例<10%时,对出水TOC没有影响;反冲洗废水的直接回流利用会导致出水细菌总数有少量增加,但不会影响消毒效果,同时对总余氯衰减的影响也很小.UFC试验的结果表明,反冲洗废水直接回流利用仅会造成消毒副产物前质含量轻微升高,其增幅为4.5%～7.6%. |
| 关 键 词： | 滤池 反冲洗废水 回流利用 消毒 消毒副产物 |

| Abstract: | The effect of direct reuse of filter backwash wastewater on treated water quality was studied by jar test.The results show that the direct reuse of backwash wastewater can obviously enhance the coagulation process and lower the turbidity and residual aluminum in treated water.When the reflux ratio is less than 10%,the direct reuse of backwash wastewater has no influence on TOC in treated water.The reuse slightly increases total bacteria count in treated water,but has no impact on disinfection and only sligh... |
