中水回用系统中高密度沉淀池出水浊度的控制研究

Study on turbidity control of high density sedimentation tank effluent in reclaimed water reuse system

高密度澄清池是利用池中的泥渣与混凝剂以及原水中的杂质颗粒相互接触、吸附、沉淀、以达到泥水分离目的的净水构筑物,近年来在水处理领域得到了越来越多的应用和研究。首先介绍了中水回用系统的工艺流程及水质,其次介绍了高密度沉淀池出水浊度对后续单元的影响,并提出高密度沉淀池出水浊度的控制方法。

the high density clarifier is a water purifying structure which uses the mud slag in the pool and the coagulant and the impurity particles in the raw water to contact,adsorb,precipitate and achieve the purpose of separating mud water. In recent years,it has been applied more and more widely in the field of water treatment. First,the technological process and water quality of reclaimed water reuse system are introduced. Secondly,the influence of turbidity of high density sedimentation tank on subsequent units is introduced. The control method of turbidity of effluent from high density sedimentation tank is also proposed.
