摘要
目的了解广州市农村地区改厕粪便无害化处理效果及其影响因素。方法于2013年6—7月,在广州市7个农村地区分层随机抽取155户改厕农户户厕开展现场调查,采集粪水样品检测粪大肠菌值、寄生虫卵沉降率、血吸虫卵和钩虫卵,采用统一的问卷调查用户家庭基本情况、厕所建造基本情况、户厕卫生管理、使用情况及厕所建设质量。结果广州市农村改厕粪便无害化效果总合格率为83.2%,主要不合格项目为粪大肠菌值(85.16%)。经logistic回归分析,结果显示,保持厕所清洁、粪便定期清除、施肥时从第三格取粪、政府投入资金和生活污水不排入化粪池能够有效提高厕所粪便无害化效果的合格率(P<0.05)。结论应进一步加强厕所的日常卫生管理,同时争取政府的改厕经费补助,从而达到提高农村改厕粪便无害化效果的目的。
