摘要
用菖蒲、芦苇2种植物和石英砂、活性炭、煤矸石3种基质构建了6套人工湿地系统,分别命名为装置1#,2#,3#,4#,5#,6#,探究了植物、基质及水力停留时间对处理农村生活污水效果的影响。结果表明,随着水力停留时间的增加,6套装置系统对各污染物的去除效果均越来越好,当水力停留时间为48 h时,6套装置系统对各污染物的去除效果达到最佳。菖蒲-活性炭3#装置在48 h水力停留时间下,化学需氧量(chemical oxygen demand,COD)、氨氮(ammonia nitrogen,NH_(4)^(+)-N)、全磷(total phosphorus,TP)的去除率分别为97.34%,92.19%,79.50%,出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准及以上,说明该系统可用于农村生活污水处理。
Six constructed wetland systems,named device 1#,2#,3#,4#,5#and 6#,were constructed with two kinds of plants,calamus and reed,and three kinds of substrates,quartz sand,activated carbon and coal gangue.The effects of plants,substrates and hydraulic residence time on the treatment of rural domestic sewage were investigated.The results showed that the removal effect of the six device systems on each pollutant became better and better with the increase of hydraulic residence time.When the hydraulic residence time was 48 h,the removal effect of the six device systems on each pollutant reached the best.Under 48 h hydraulic retention time,the chemical oxygen demand(COD),ammonia nitrogen(NH_(4)^(+)-N),and total phosphorus(TP)of calamus-activated carbon device 3#were 97.34%,92.19%and 79.50%,respectively.The effluent quality reached the first class B standard or above of the"Pollutont Discharge Standard of Urban Sewage Treatment Plants"(GB 18918—2002),indicating that the system could be used for rural domestic sewage treatment.
