摘要 本文对缺氧变速生物滤池 + SASBR工艺 ,在常温下处理城市污水的效果及主要影响因素进行了试验研究。结果表明 :在进水 CODCr均值为 2 1 5 .4mg/L左右、NH3 - N为 2 7.3mg/L、SS为91 .6mg/L时 ,经过本工艺的处理后 ,其出水 CODCr为 2 0 .0~ 2 5 .0 mg/L,NH3 - N为 9.0~1 1 .0 mg/L,SS约为 1 0 .0 mg/L,满足国家综合排放 ( GB8978- 1 996)一级标准的要求。 The municipal wastewater treatment by anaerobic biofilter(AF) and short aeration sequencing batch reactor(SASBR) was studied through experiment under ambient temperature. COD Cr of the municipal wastewater averages 215.4mg/L, NH 3-N is 27.3mg/L, SS is 91.6mg/L. After the treatment by AF and SASBR, COD Cr declines to 20.0~25.0mg/L, NH 3-N to 9.0~11.0mg/L,SS to about 10.0mg/L, and they all can meet the first discharging index of Wastewater Discharging of Chinese National Standard(96).
