活性污泥法在火电厂生活污水处理中的应用
|
摘要
生活污水约占火力发电厂废水总量的10%,其有效处理对全场废水达标排放和回收利用具有重要意义。选择火电厂生活污水处理最常用的两种活性污泥法处理技术,对常规活性污泥法和序批式活性污泥法的工艺流程和特点进行介绍,并分析在实际应用中影响活性污泥处理效果的水质、水量和温度等问题,提出了相应的解决方案。
Domestic sewage accounts for around 10% of the total amount of wastewater produced by coal-fired power plant. The applicable treatment plays an important role in its permissible discharge and recycling. Conventional activated sludge process and sequencing batch reactor activated sludge process are two frequently-used methods in treating domestic sewage of coal-fired power plant. In this paper, the technological process and characteristic of the two treatments are introduced. Factors(such as the quality, quantity and temperature of water) influencing the practical application of activated sludge process are analyzed, and several corresponding solutions are proposed.
