【摘要】 本文研究了微絮凝变孔隙深层过滤处理低浊度废水时,滤料粒径、絮凝剂种类、投加量、滤速等因素对过滤效果的影响。试验结果表明:在达到相同出水水质的情况下,由于变孔隙结构等原因,该系统具有用药量省、阻力损失小、出水量大及整床过滤效能好等优点。更多还原

【Abstract】 In this paper, the effect of some factors such as diameter of filter medium, sort and quantity of flocculant, filtration velocity etc. on filtering characteristics is studied in a treatment of low turbidity wastewater by using microflocculation variable void deep filter. It is found from the experiment that the system has the advantages of saving on quantity of chemicals, reducing loss of resistance, augmenting quantity of effluent water and having fine filtering efficiency of the whole bed under the same quality of effluent water.更多还原
