改建厕所是“两管五改”的重要内容。在改建厕所时,除搞好粪便无害化、防臭设施外,还应改进贮粪池的防蛆设施,这是改厕的关键问题之一。蛆只有爬到干的地方,才能变蛹羽化。近两年,在我们所改建的深坑滑坡式厕所中(按武汉军区军事医学研究所设计的74型厕所),由于没有掌握蛆的爬行特点,使不少已改建的厕所不能防蛆。为了解决防蛆,我们对蛆的爬行能力,做了以下观察,并改进了防蛆设施。一、蛆的爬行能力观察 1.蛆在贮粪池壁上爬行的能力,共观察167个蛆。在干池壁上竖爬,分别爬高统计是:6～10厘米者158个,占总数的94.6%;11～15厘米者7个,占4.2%;16
Remodeling toilets is an important part of “two tubes and five changes.” When remodeling toilets, in addition to doing a sound decontamination, deodorant facilities, but also should improve the anti-maggot facilities of the septic tank, which is one of the key issues of toilet. Maggots climb to dry place, in order to become pupa eclosion. In the past two years, in the deep-pit landslide toilets that we have rebuilt (Type 74 toilets designed by the Military Medical Research Institute of Wuhan Military Region), many remodeled toilets can not prevent maggot because they do not have the characteristics of maggot crawling. In order to solve the anti-maggots, we made the following observation on the maggots crawling ability and improved the anti-maggots facilities. First, the maggot crawling ability observation 1 maggot crawling in the wall of the capacity of septic tanks, a total of 167 maggots observed. Climbing up in the dry pool wall, respectively, climbing statistics are: 158 persons 6 to 10 cm, accounting for 94.6% of the total; 7 to 11 to 15 cm, accounting for 4.2%; 16
