高密度沉淀池工艺在水处理领域中的应用

Application of High Density Sedimentation Tank Technology in Water Treatme nt Field

在水体治理要求不断提升的背景下,国家对污水处理厂的排放标准逐步提高。大部分污水处理厂工艺亟需进行提标改造。高密度沉淀池具有占地面积小、出水水质高、药剂投加量低、集成化与自动化程度高等特点,越来越多的应用于生活污水、工业废水、市政供水和暴雨水处理中。本文阐述了高密度沉淀池的工艺原理,介绍了高密度沉淀池在水处理领域的应用现状,讨论了影响高密度沉淀池在运行过程中的主要因素,并对未来的发展提出建议。

Under the background of the continuous improvement of water treatment requirements,the national discharge standards for sewage treatment plants are gradually improved.Most sewage treatment plant processes need upgrading.High density sedimentation tank has the characteristics of small area,high effluent quality,low dosage of pharmaceutical,high degree of integration and automation,more and more used in domestic sewage,industrial wastewater,municipal water supply and rainstorm treatment.This paper describes the process principle of high density sedimentation tank,introduces the application status of high density sedimentation tank in the field of water treatment,discusses the main factors affecting the operation of high density sedimentation tank,and puts forward suggestions for the future development.
