提高平流沉淀池沉淀效果的研究与探讨

Research and discussion on improvement of setting effect in rectangular settling tanks

试验研究了在模拟平流沉淀池中,设置挡板、溢流堰对浊度去除效果的影响,以及在沉淀区中投放短管填料对浊度去除效果的提高。通过控制不同进水流态、短管填料不同投加方式、不同投放位置、不同投放量的对比,提出提高浊度去除率的最优方法。

The influence of removal rate of turbidity by setting up baffle, over falling weir was studied in the imitating rectangular settling tanks,and improvement of the removal rate of turbidity by throwing stub tube fillers in setting district was also studied in this experiment. Through controlling different flowing state of the influent, adding methods and position of the stub tube fillers, the best method of improving the removal rate of turbidity was proposed.
