【摘要】 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: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 on filtering characteristics is studied in a treatment of low turbidity wasterwater using microfioccula-tion variable void deep filter,these factors include diameter of filter medium.sort and quantity of flocculant,filtration velocity etc.lt is found from the experiment that the system has the advantages of saving quantity of chemicals,reducing loss of resistance, large effluent water flow and having fine high filtering efficiency of the whole bed under the same quality of effluent water更多还原
