摘要
对一体式膜生物反应器进行了中试实验,主要研究了该工艺对生活污水中各种污染物质的去除效果。结果表明,MBR稳定运行期间不仅能有效地抗击各种冲击负荷,而且出水水质稳定,对CODCr、浊度、NH3-N的去除率分别为94%、99%和98%;中试工艺对TN、TP也有较好的去除效果;膜组件对水中微生物的去除率在99.99%以上,保证了工艺出水回用的安全性和可靠性。
The performance of A/O MBR in the treatment of municipal wastewater for reuse was studied in this paper. The results showed that the treatment system had a strong resist against shock loading, and the removal efficiency of CODCr turbidity, NH3-N was 94 %, 99 % and 98 % respectively. The treatment system simultaneously showed a good performance for TN and TP. The removal efficiency of microorganisms was excellenct at 99.99 %. The effluent had good performance in safety and reliability in terms of sanitation.
