摘要
分别考察了在不同水力停留时间、溶解氧、污泥回流比等条件下,倒置A2/O工艺的脱氮效果和有机物去除效果,结果表明,对于城市生活污水而言,当好氧区水力停留时间为6 h,且好氧区前端溶解氧浓度为3 mg/L、中后端为2 mg/L,污泥回流比为200%时工艺能获得较好的脱氮效果和有机物去除效果。
This paper investigates the removal effect of organic matters and nitrogen of inverted A^2/O process at different HRT,DO,sludge return ratio and so on.The result showed that for the urban wastewater,the inverted A^2/O process has more stronger removal effect with HRT 6 h and DO 3 mg/L ahead of aerobic area,DO 2 mg/L at the middle and rear of aerobic area,sludge return ratio 200%.
