摘要
以某城市污水厂生化出水为研究对象,通过试验研究聚合氯化铝铁中Al_(2)O_(3)与Fe^(3+)的含量变化对除磷效果的影响。同时,研究了聚合氯化铝铁的投加量对除磷效果的影响。结果表明:聚合氯化铝铁中Al_(2)O_(3)含量为9.0%,Fe^(3+)含量为0.8%时处理效果最佳。而出水的聚合氯化铝铁药剂用量在120 mg/L时,TP出水浓度为0.09mg/L,可确保污水厂出水总磷TP≤0.10mg/L的内控排放标准。
TTaking the biochemical effluent of an urban sewage treatment plant as the research object,this paper studies the influence of changes in the content of Al_(2)O_(3) and Fe^(3+)in polyaluminum ferric chloride on phosphorus re-moval efficiency through experiments,and also studies the effect of the dosage of polyaluminum ferric chloride on phosphorus removal efficiency.The results show that the best treatment effect is achieved when the Al_(2)O_(3) content is 9.0%and the Fe^(3+)content is 0.8%in polyaluminum ferric chloride.When the dosage of polyaluminum ferric chloride agent in the effluent is 120 mg/L,the effluent concentration of TP is 0.09 mg/L,which can ensure the in-ternal control discharge standard of TP≤0.10 mg/L in the sewage effluent.
