摘要
研究了升流式曝气生物滤池处理农村生活污水的性能参数。结果表明,HRT=3.2 h、气水比为5∶1的工艺条件下,升流式曝气生物滤池能保证出水CODCr、NH3-N、BOD5、SS均达到GB8978-1996规定的1级排放标准,且充分利用曝气量。
The property parameters in rural domestic wastewater treatment with up-flow biological aerated filter were studied. The results showed that the optimum condition was HRT of 3.2 h, gas-water ratio of 5：1, under which the effluent concentration of CODcr, NH3-N, BOD5 and SS were suitable to the first grade discharge standard of GB8978-1996.
