According to the regulation of degressive effusion flux of uf during the period time of alga - blooming , this paper also favors the optimum function parameter of uf . when the water temperature is 30 , the optimum tmp is 0 . 07mpa , the optimum hydraulic re - wash period is 40min , the optimum chemical wash period is 330min ; when the water temperature is 20 , the optimum tmp is 0 . 07mpa , the optimum hydraulic re - wash period is 60min , the optimum chemical wash period is 960min 并且根据高藻期超滤处理沉淀池出水通量下降的规律,提出了超滤运行的最佳工艺参数,即水温30时初始透膜压力,水力反冲洗周期,化学清洗周期分别取0 . 07mpa , 40min , 330min ;水温20时以上数值分别为0 . 07mpa , 60min , 960min 。
The studies on flocculation parameters of high turbidity water are completed more integrally , including establishing the equation about the relationship between the covering ratio of flocculent on silt surface 6 and the surface area of silt particles s . the re - concentration law of thickener underflow is studies 建立了一定沉速下，泥沙固体颗粒表面覆盖率与泥沙颗粒表面积s间的函数关系式；较系统地完成了高浊度水絮凝参数的研究。研究了高浊度水沉淀池排泥的再浓缩规律。
It ' s the key to implement the full - scale automatization of water plant how to design and develop more rational control of adding material . and figuring out the precise quantity control of precipitator alum in the deposition pools is an important problem of the whole water industry 设计开发更合理适用的加料实时控制方式，解决水厂沉淀池中明矾混凝剂的投加量控制问题，建立完善的自动化加料系统，是水厂生产实现全面自动化的关键，也是摆在整个水处理行业面前的重要课题。
It ca n ' t realize adding precipitator by measure , which traditionally depends on naked eyes to detect the quantity of adding alum in the deposition pools . as a result , there are the problems such as consuming alum without measure and difficulty to control water quality , which is n ' t adaptive to great demand of water quality 对于水厂沉淀池中明矾添加量的检测，传统的方法是通过人的肉眼进行观察，无法达到真正意义上的计量投加，直接造成明矾混凝剂的过分消耗、水质情况难于掌握等问题，与日益提高标准的水质要求不相适应。
