摘要
采用ASBR+SBR工艺,进行处理小流量生活污水的试验研究。结果表明,先通过ASBR反应器对污水起到平衡、均化作用,再通过SBR反应器实现污水的脱氮除磷。试验出水CODCr浓度为21～43mg·L-1,去除率达到85～93%;出水NH3-N浓度为3 3～9 5mg·L-1,去除率达到65～81%;出水TP浓度为0 32～0 63mg·L-1,去除率达到87～95%。
Study was made on treatment of small flux wastewater by two-stage SBR process. The results showed that the wastewater was balanced and equaled through SBR1 and the nitrogen and phosphorus was removed by SBR2. The value of CODcr, NH3-N, and TP at the entrance were successively in the range of 21～43mg/l, 3.3～9.5mg/l, and 0.32～0.63mg/l, the removal rate of CODcr, NH3-N, and TP were respectively 85～93%, 65～81%, and 87～95%.
