| 摘 要： | 以序列间歇式活性污泥法(序批式反应器,SBR)侧流除磷工艺为基础,以厌氧释磷液的富磷污水侧流化学除磷过程为研究对象,围绕磷资源回收,探索低成本化学除磷方法.结果表明,富磷污水化学除磷过程可以缓解碳酸盐对除磷药剂的竞争.当侧流化学除磷池以ρ(P)=3~5 mg/L作为出水磷质量浓度控制目标时,单位药剂(CaO/mg)除磷量为0.6~0.2 mg;除磷药剂的用量为城市污水直接化学除磷系统的7.7%~8.4%;处理单位体积(1 m3)ρ(P)=50 mg/L的富磷污水时,可以得到0.27 kg含磷率为17%的化学污泥.SBR侧流除磷工艺可以回收污水中65%的磷,当提高SBR运行周期n和充水比λ时,磷的回收率有望进一步增加.
