| 摘 要： | 文章主要采用烧杯试验进行硅藻土精及复配硅藻土精强化混凝技术去除模拟洗浴废水中磷、氮的效果研究。试验结果表明:硅藻土强化聚合氯化铝(PAC)后能够提高废水中的总磷(TP)、总氮(TN)、氨氮(NH3-N)的去除率。当PAC投加量为150 mg/L时,通过混凝工艺对TP、TN、NH3-N去除率分别是91%、6%、21%,采用硅藻土强化PAC混凝工艺对TP、TN、NH3-N去除率分别为95%、58%、26%;复配硅藻土强化PAC混凝工艺对TP、TN、NH3-N去除率分别为95%、42%、64%。采用硅藻土精及复配硅藻土精强化混凝技术较生物技术脱氮除磷向大气排放二氧化碳等气体量少。

| Abstract: | The paper mainly adopt beaker tests to treat simulation bath wastewater of phosphorus and nitrogen with diatomite and compound diatomite pure enhanced coagulation technology.Test results showed that： the diatomite strengthening the coagulation of PAC can increase the phosphorus and nitrogen efficiency.When the PAC dosing quantity for 150 mg/L,through the coagulation process the total phosphorus（TP）,total nitrogen（TN）,ammonia nitrogen（NH3-N） removal respectively is 91 %,6 %,21 %,using diatomite enhanced flocculation process of PAC the TP,TN,NH3-N removal respectively is 95 %,58 %,26 %.Compound diatomite enhancing the coagulation process of PAC,the TP,TN,NH3-N removal respectively is 95 %,42 %,64 %.Diatomite pure enhanced coagulation technology discharging carbon dioxide is less than by biological technology. |
