讨论提高污泥浓度对市政污水处理的影响
|
摘要
随着我国国民经济不断发展,城市化进程不断加快,水资源的需求量越来越大,我国水资源的应用压力也变得越来越大。现在我国绝大多数的污水处理均选取活性污泥法这种污水处理手段,但是活性污泥法会产生非常多的剩余污泥,这些污泥包含非常多的有毒有害物质,只有有效处理,污泥才能够变废为宝,才不回威胁到环境安全。文章探究了城市污水处理厂所产生的污泥的特点,说明了处理污泥所要遵守的一般原则,污泥的科学合理利用,并通过实验查看以减低排泥量为前提,提高污泥浓度,分析了污泥混合液悬浮固体浓度以及化学需氧量之间的关系、混合液挥发性悬浮固体浓度以及混合液悬浮固体浓度之间的关系、氨氮以及混合液悬浮固体浓度这两者之间的关系。
With the continuous development of China's national economy, city to speed up the process, the demand of water resources has become increasingly large; using the pressure of water resources in China has become more and more. Now the vast majority of sewage treatment were selected activated sludge method which is a kind of wastewater treatment methods in China, but activated sludge process will produce a lot of surplus sludge, the sludge contains a lot of toxic and harmful substances, only an effective treatment, sludge can turn waste into treasure, would not return to the threat to the environment safety. The paper explores the urban sewage treatment plant sludge characteristics, illustrates the general principles to be followed for sludge treatment, sludge scientific rational use, and through the experiment to see to reduce the amount of mud as the premise, raise the concentration of activated sludge, analyzes the relationship between the relationship between the relationship between sludge mixed liquor suspended solids concentration and chemical oxygen demand amount, mixed liquor volatile suspension solid concentration and mixed liquor suspended solids concentration, ammonia nitrogen and mixed liquor suspended solids concentration of the two.
