福建省安溪县吾邦村地区三格化粪池出水水质调查

Investigation on effluent quality of septic tanks with three boxes in Wubang Village, Anxi County, Fujian Province

为了解农村现有三格化粪池污水处理情况,调研人员于2018年7~8月在福建省安溪县吾邦村,随机对20户农户进行现场取样,检测未经处理的家庭污水排放口和三格化粪池出水的各项水质指标。通过对比发现,三格化粪池的使用在一定程度上改善了以往污水直接排放的危害,但既有的化粪池出水水质仍有部分指标超标,若将其排放至农田及流域,将对土壤与水域造成不可逆转的二次污染。调研结果表明,我们仍需对既有的三格化粪池进行改进,对化粪池出水需进一步处理。

In order to understand the sewage treatment situation of the existing septic tanks of three boxes in rural areas,the researchers randomly sampled 20 households in the Wubang Village of Anxi County,Fujian Province from July to August 2018 to conduct on-site sampling for detection of untreated domestic sewage discharges and the water quality indicators of septic tanks with three boxes.Through comparison,it is found that the use of septic tanks with three boxes has certainly reduced the harm of direct release of sewage in the past,but still have some some water quality indicators of septic tank effluent exceeding the standard.If it flows to farmland and watershed,it will cause irreversible secondary pollution to soil and water.The survey indicated that we still need to improve the existing septic tanks with three boxes for further treatment of effluent from the septic tank.
