Research on the Feasibility of Using Domestic Wastewater Irrigating Green Lands

Abstract

本文提出“采用生活污水浇灌绿地”的新思路,拟采用化学强化一级处理和消毒的方法对生活污水进行预处理后浇灌绿地,其工艺流程如下:生活污水—去除悬浮物—消毒—绿地浇灌本文通过对以下三方面的主要问题的研究,探讨该方法的可行性:(1)采用生活污水浇灌绿地是否引起植物生长不良;(2)生活污水浇灌绿地是否污染绿地土壤;(3)生活污水浇灌绿地是否污染地下水。通过近10个月的模拟绿地浇灌试验,研究结果表明:(1)采用生活污水浇灌绿地不但不对绿地的植物生长产生不良影响,相反还促进了植物的生长发育;(2)生活污水浇灌绿地后,绿地土壤并没有产生重金属的累积,因此认为绿地土壤不会受到污染;(3)绿地土壤对浇灌的污水具有...The thesis put forward a new method of using domestic wastewater to irrigate the green lands. In research we use “Chemically Enhanced Primary Treatment” and “Disinfection” as pre-treatment. The process are following. domestic wastewater — Treatment for removing SS — Disinfection — Green lands irrigation The thesis studied on the feasibility of using domestic wastewater to irrigate the green ...学位:工学硕士院系专业:海洋与环境学院环境科学与工程系_环境工程学号:20033403
