摘要
通过试验分析了兼性生化反应池出水中残余有机污染物的 COD组成 ,指出反应池内兼性活性污泥的生物吸附絮凝性能是反应池在负荷较高时污染物去除效率较低的主要原因。为保证系统出水达标 ,针对兼性系统的出水水质 ,利用化学混凝、好氧生物吸附絮凝和生态渗滤方法进行了 3套后续深度处理工艺方案的试验研究并对其进行了技术经济比较 。
Based on the experiments, this paper analyzed the composition of COD of the outflow from facultative bio chemical process systems. It indicated that the characteristic of adsorption and flocculation of facultative activated sludge is the main cause of the reduction of treatment efficiency while adding the loads of treatment systems. In order to ensure the quality of terminal outflow,3 kinds of deep treatment processes were suggested: chemical flocculation process, anaerobic biological adsorption and flocculation process and ecological leaching soil process. The detailed technical and economic comparisons of different processes were also provided.
