摘　　要：目的评价阁楼式堆肥厕所无害化效果。方法按粪便无害化标准对阁楼式堆肥厕所粪大肠菌群和蛔虫卵的去除效果进行检测,对沙门氏菌噬菌体28B的去除效果进行试验研究。结果在90 d的堆肥时间内,沙门氏菌噬菌体28B浓度由初始浓度108 pfu/g降低到不能检出,蛔虫卵死亡率可达99.8%,粪大肠菌值从初始10-9升至10-2。结论阁楼式堆肥式厕所是好氧发酵的一种厕所模式,可使粪便中的病原体和寄生虫卵失活,达到粪便无害化卫生标准的要求。Objective To evaluate sanitary effects on attic type composting latrine. Methods The removal of fecal E. Coli and ascarid eggs on attic type eomposting latrine was assessed, and the removal of sahnonella bacteriophage 28B was studied , according to sanitary standards for the non- hazardous treatment of night soil.Results Within 90 days of eomposting, the concentration of salmonella bacteriophage 28B was reduced from 108 pfu/g to negative results, death rate of asearid eggs reached 99.8 %, and the concentration of fecal E. coli increased from 10^-9 to 10^-2. Conclusion Attic type composting latrine is a latrine mode of aerobiotie ferment, which makes pathogen and asearid eggs of night soil inactivate to attain the requirements of sanitary standard for the non - hazardous treatment of night soil.
