通过连续三年对浙江农村卫生厕所无害化效果的监测,结果显示农村户厕能达到粪便无害化卫生标准的仅为40%左右。成蝇和蛆密度均与温度有关,夏季的合格率明显低于冬季。经对三格式化粪池第一池和第三池的各项指标的检测,两池之间粪大肠菌值和亚硝酸盐氮均无差异,而氨氮、硝酸盐氮有差异。 After three consecutive years of monitoring the detoxification effect of rural rural lavatories in Zhejiang Province, the results showed that only about 40% of the rural hygienic standards for toilet decontamination were reached. The density of adult flies and maggots was related to temperature, and the passing rate in summer was significantly lower than that in winter. There was no difference in fecal coliform and nitrite nitrogen between the two pools, but there were differences between ammonia nitrogen and nitrate nitrogen in the three types of septic tanks in the first and third ponds.
