摘要
氮和磷的控制在污水处理和污水处理装置的设计中越来越重要。因为只有氮和磷两者合起来才能改变水质的特性,因此去除其中一种或两者都去除就可以实现控制手段。根据氮在水中的存在形态及其危害,介绍了炼油污水中氮的分布及其去除方法。去除方法中主要介绍了两种:一种是SBR(Sequencing batch reactor,间歇式或序批式活性污泥法),第二种是A/O脱氮工艺。
Nitrogen and phosphorus are the principal nutrients of concern in treated wastewater discharges. Therefore, the control of nitrogen and phosphorus is becoming increasingly important in water quality management and in the design of wastewater treatment plants. Because both nitrogen and phosphorus can impact receiving water quality, the discharge of one or both of these constituents may have to be controlled. Including the existing state of nitrogen in water and its ham. The distribution of nitrogen in refinery sewage, and its removing method are also put forward. The method 1 is SBR and the method 2 is A/O Denitrifieation Process.
