摘要
单户型家庭生活污水盆景式处理是以人工湿地为基础的分散式废水处理方法。通过接近1年的试验对其净水效果进行研究,结果表明,它对化学需氧量(CODCr)、生物需氧量(BOD5)、氨氮(NH3-N)、总磷(TP)、总固体悬浮物(TSS)的去除率可分别达到92.72%、96.28%、79.06%、85.11%、95.83%。出水水质分别达到33.8mg/L、19.2mg/L、0.8 mg/L、0.7 mg/L、8 mg/L,基本符合国家一级排放标准,部分指标如BOD5、NH3-N等甚至可以达到或优于城市生活杂用水水质标准。同时它也可以作为室内盆景用水,起到美化环境净化空气的作用。
Miniascape Type Household Domestic Sewage Treatment belongs to decentralized treatment based on constructed wetlands.A test of water purification was conducted for nearly one.The results showed that the removals of CODcr,BOD5,NH3-N,TP and TSS reached 92.72%,89.57%,79.06%,85.11% and 95.83% respectively;and the effluent quality were 33.8mg/L,19.2 mg/L,0.8 mg/L,0.7 mg/L and 8 mg/L respectively,which meet the first class of the national wastewater discharge standard and some indicators such as BOD5 and NH3-N reached the undrinkable water quality standard or better.Additionally,it can also act as a bonsai to beautify the indoor environment and clean indoor air.
