摘要
污水处理过程可分为2个过程:生化反应去除污染物,物理手段固液分离去除污染物并集中处理。文章分析了以硅藻土、磁分离和微砂沉淀为代表的沉淀技术,以动态砂、膜分离和滤布为代表的过滤技术,同时探讨了其在环境工程中的应用,为后续污水处理提供了参考。
The sewage treatment process can be divided into two processes:biochemical reaction to remove pollutants,physical means solid-liquid separation to remove pollutants and centralized disposal.The article analyzes the precipitation technology represented by diatomaceous earth,magnetic separation and micro-sand precipitation,and the filtration technology represented by dynamic sand,membrane separation and filter cloth.At the same time,its application in environmental engineering is discussed,which can providereference for subsequent sewage disposal.
