溶解氧对人工湿地系统除磷性能影响研究

Study on the Effect of Dissolved Oxygen on Phosphorus Removal Performance of Constructed Wetland System

探究不同溶解氧下人工湿地系统去除水样中总磷性能,采用钼锑抗分光光度法测定不同溶解氧下设备出水总磷量,得到了模拟装置除磷率曲线。从曲线可以看出,再提他条件不变情况下,溶解氧对人工湿地系统除磷性能影响不大,生产使用时不需特别注意溶解氧含量。

The removal performance of constructed wetland system for total phosphorus in water samples under different dissolved oxygen conditions was investigated. The total phosphorus content of equipment effluent under different dissolved oxygen conditions was measured by Mo-Sb anti-spectrophotometry, and the phosphorus removal rate curve of simulated device was obtained. It was seen from the curve that the dissolved oxygen had little effect on the phosphorus removal performance of the constructed wetland system under the same condition, and there wsa no need to pay special attention to the dissolved oxygen content during production and use.
