新型人工湿地污水处理系统复氧效果研究

介绍了新型人工湿地的工艺特点，并对自然跌水复氧和自然沟槽复氧两种复氧方式的复氧效果进行试验研究，结果表明：1．5m高的跌水，其复氧量在2．2mg/L-3．3mg/L之间，且由复氧数学模型得出复氧的预测值与实测值基本一致；沟槽的复氧效果与槽长呈正比关系，且4m沟槽的复氧量可达到3．0mg/L；试验得出跌水复氧的效果要优于沟槽复氧。

Study on the Effect of Reaeration in the New Type of Constructed Wetlands Wastewater Treatment System

The paper introduced the craft characteristics of a new type of constructed wetlands,also the two kinds of reaeration,influent-fall reaeration and trough reaeration,were investigated by the experiments.The results show that the reaeration quantity is 2.2 mg/L～3.3 mg/L throught Influent-fall reaeration of 1.5 meters' fall,also the theory values of reaeration model keep consistent with the experiments.The experiments also discover that the direct proportion relation assumed between reaeration effect and the length of trough,besides,the reaeration quantity can reach 3.0 mg/L along 4 meters' trough.The study shows that the effect of fall reaeration is better than trough reaeration.
