目的 :论证引进泰国水封便器应用到我国农村定型户厕后的推广应用价值。方法 :在观察现场建造不同类型的户厕 ,均应用泰国水封便器 ,分别对其粪便无害化处理效果、肥效、厕内臭气浓度及其对环境卫生质量的影响进行对比监测和评估。结果 :我国推广的几种定型户厕增设水封便器后 ,保氮效果明显 ,厕内NH3、H2 S、吲哚含量可分别减少 4 2— 4 4 % ;18— 2 7% ;70— 75% ,粪大肠菌值和蛔虫卵沉降率亦能达到国家《粪便无害化卫生标准》的要求 ;可使成蝇密度比对照点降低 75.8%— 76 .9% ,每百克土壤中蛔虫卵含量比对照点减少 93.3%— 97.1%。结论 :泰国水封便器增设在我国农村定型户厕有重要的推广应用价值。

Purpose:Experiments were carried out to testify the popularizing and applying value or Thai water-sealed urinal's being introduced to finalized household toilets in our countryside.Methods:different types of household toilet assembled with Thai water-sealed urine were constructed on the spot of observation.,and the excrement and urine harmlessly treating effect;fertilizer efficiency;stink concentrition in toilet and its influence on quality of environmental sanitation were respectively comtrasted,supervised and evaluated.Result:Several types of popularized finalized household toilets in our country,after being assembled with Thai water-sealed urinal,had obvious N-preserving effect;and the content of NH 3,H 2S,and droxyindole decreased respectively by 42～44%,18～27%;and the value of Fecal Coliforms and subsiding rate of ascarid ovum also reached the requirements of the national Excrement and Urine Harmlesslization Sanitation Standard,the density of adult flies was 75.8～76.9% lower than the contrast spot,and the ascarid ovum content per 100g soil was 93.3～97.1%lower than the contrast spot. Conclusion:Finalized household toilets in our country assembled with Thai water-sealed urinal has important popularizing and applying value.
