摘要
通过试验进一步证实了在高浊度水处理中以泥沙颗粒表面积为依据的聚丙烯酰胺投加自控数学模型是可行的,并在辐流式沉淀池研究中以沉淀池中浑液面的位置变化作为投药量数学模型的后馈信号。从而首次在高浊度水处理时完成了闭环的自控投药系统.
In this paper,it was proved through water treatment plant test that the method,determining the flocculant dosage for high-turbid water clarification according to total surface area of sediment particles in raw water from the Yellow River,is practicable.In the meantime the basic mathematica.model for automatical dosing on industrial water plant was established and the variability of suspension interface level in radial settling tank with diameter 100m was successfully dctcmined by interface-meter.This signal of variability can be taken for feedback parameter that is used for correcting automatical flocculant dosage.Therefore,the automatical close-cycle control system is first developed in our country for high-turbid water treatment.
