目的对嵊州市两种农村改厕处理污水模式的实际效果进行评价,为农村改厕工作提供科学依据。方法采用随机抽样方法抽取10个三格式和四格式的卫生厕所,对其基本情况、常规监测指标、污染物指标进行监测与评价。结果嵊州市厕所的常规监测指标基本能达到无害化卫生标准,氨氮、COD、BOD5指标达标率较低;三格式卫生厕所的氨氮、总磷、COD和BOD5等指标的无害化效果好于四格式化卫生厕所。结论部分卫生学与污染指标去除率和达标率不高,三格式无害化效果优于四格式厕所,应加强农村改厕建造模式工艺设计、技术指导和验收,提高无害化效果。
Objective To evaluate the practical effect of two kinds of rural lavatories on sewage treatment in Shengzhou City and provide a scientific basis for rural lavatories. Methods A total of 10 sanitary and sanitary toilets with three formats and four formats were selected by random sampling method to monitor and evaluate the basic conditions, routine monitoring indicators and pollutant indexes. Results The routine monitoring indexes of toilets in Shengzhou City basically met the hygienic standard of sanitation, and the compliance rates of ammonia nitrogen, COD and BOD5 indexes were lower. The three types of sanitation lavatories had better detoxification effect of ammonia nitrogen, total phosphorus, COD and BOD5 Four formatted sanitary lavatories. Conclusion Some of the indicators of hygiene and pollution removal rate and compliance rate is not high, three forms of harmless effect is better than the four-style toilet, should strengthen the rural lavatories construction mode design, technical guidance and acceptance, improve the harmless effect.
