钩虫卵的死亡速度1.厕所貯粪池貯存:自1959年8月15日及18日,先后在两个连队厕所中开始积存粪便(包括粪、尿及冲洗厕所的水),在积存过程中禁止掏取和消毒、杀虫。清洗厕所按正常进行,不加任何限制,各积存半月后,开始进行观察。观察期间,杜绝新粪和雨水渗入,并加盖貯存。如以积粪完了开始观察的当天的钩蚴数为基数(100%),来比较貯存时间和钩虫卵死灭速度,可以看出两个厕所貯粪池在貯粪15日后钩虫卵死灭90%以上,30日后全部死灭(见表1)。2.粪坑中貯存:自1959年8月30日积存一周间粪便,加水稀释使水与粪便之比为5此1,分装于4个粪坑内,其中两坑(坑一、坑二)按25%加入马粪,另两坑(坑
Hookworm egg death rate 1. Toilet septic tank storage: Since August 15, 1959 and August 18, successively in two company toilets began to accumulate excrement (including manure, urine and toilet flushing water), during the accumulation process Prohibit digging and disinfection, insecticide. Cleaning the toilet as normal, without any restrictions, the accumulation of a half months later, began to observe. During the observation period, stop the infiltration of new manure and rain, and stamped storage. For example, when the number of cercariae on the day of starting the observation of feces was 100%, the storage time and the speed of decay of hookworm eggs were compared. It can be seen that the hookworm eggs were destroyed in the two latrine septic tanks after storage for 15 days % Or more, all died after 30 days (see Table 1). 2. Cesspool storage: since August 30, 1959, a week of accumulation of stool, diluted with water to make water and stool ratio of 5 this 1, sub-packed in 4 cesspools, of which two pit (Pit 1, Pit 2) 25% added horse manure, the other two pit (pit
