摘要
采用序批式活性污泥反应器,分别在厌氧-好氧、厌氧-缺氧-好氧运行方式下,研究了分段进水强化城市生活污水同步脱氮除磷的效果。结果表明,水总体积的30%进入厌氧段即可满足磷酸盐的去除对碳源的要求;SBR以厌氧-缺氧-好氧方式运行时,缺氧段NO3--N的质量浓度为20 mg·L-1时,可完全去除磷酸盐,并且随着二次分配的碳源增加,反硝化脱氮的效果明显提高,出水时硝酸盐氮含量大幅减少,获得了同步脱氮除磷的效果。
In the reactor of SBR, the experiment of nitrogen and phosphorus removal was made by reasonable allotment of influent. Results showed that the request to the carbon source of phosphate removal could be satisfied if the influent quantity of the anaerobic segment reached 30% of the total. phosphate could be removed completely when SBR operated in aerobic/anoxic/oxic condition, 20 mg·L^-1 NO3-N being added into the reactor. In addition, with the increase of secondary allotting to carbon source, the denitrifying result improved obviously and the nitrate nitrogen concentration in effluent decreased significantly.
