沉水植物氧化塘技术对村镇污水厂尾水的深度处理效果

Advanced Treatment Effect of Tailwater in Village Wastewater Plant by Submerged Plant Oxidation Pond Technology

采用沉水植物氧化塘技术对村镇污水处理厂尾水进行深度处理,探讨其处理效果。结果表明,在水温18~26℃、水力负荷1.20 m^(3)/(m^(2)·d)的条件下,沉水植物氧化塘对尾水表现出较好的处理效果,对NH_(4)^(+)-N的去除率达到97.07%,TP去除率为30.43%,COD Cr去除率为43.60%。在国家高度重视农村环境质量提升的背景下,沉水植物氧化塘技术有着十分广泛的应用领域。

The submerged plant oxidation pond technology was used to conduct advanced treatment on the tailwater in the actual village sewage treatment plant to explore its treatment effect.The results showed that the submerged plant oxidation pond showed better treatment effect on the tailwater under the conditions of water temperature of 18-26℃,hydraulic load of 1.20 m^(3)(m^(2)·d).The removal rate of NH_(4)^(+)-N reached 97.07%,the removal rate of TP was 30.43%,and the removal rate of COD Cr was 43.60%.Under the background that the country attaches great importance to the improvement of rural environmental quality,the submerged plant oxidation pond technology has a very wide field of application.
