摘要
采用活性炭吸附法和超滤法处理建筑中水。试验结果表明,粒状活性炭对中水中溶解性有机物有较好的去除效果,当允许出水CODcr为15mg·L-1以下、炭层厚度为2m、滤速为3m·h-1、5m·h-1和7m·h-1时,吨水用炭量基本在0.2kg·m-3。超滤对水中浊度去除率在95%以上。超滤膜清洗采用洗涤剂配制的清洗液及5%的H2SO4、4%的NaOH溶液清洗,膜通量可得到较好的恢复。
Building reclaimed water treatment of wastewater was done as test by GAC and supermembrane.GAC can adsorb effectively organics in wastewater from water treatment plant.With 2m GAC thickness and below 15mg·L^(-1) of organics in water at 3m·h^(-1)、5m·h^(-1) and 7m·h^(-1) current velocity,GAC quantity used per ton water is some 0.2kg.Supermembrane test remove turbid from wastewater by over 95%.Washing supermembrane by washing solution made with detergent and 5% of H2SO4,4% of NaOH is effective.
