三格化粪池由相联的三个池子组成，中间由过粪管联通，主要是利用厌氧发酵、中层过粪和寄生虫卵比重大于一般混合液比重而易于沉淀的原理，粪便在池内经过30天以上的发酵分解，中层粪液依次由1池流至3池，以达到沉淀或杀灭粪便中寄生虫卵和肠道致病菌的目的，第3池粪液成为优质化肥。

The three septic tanks are made up of three pools connected by each other. The main is the principle that the anaerobic fermentation, the middle layer of feces and the parasite eggs are easily precipitated by the specific gravity of the parasite, and the feces are decomposed for more than 30 days in the pool, and the middle fecal fluid flows from 1 pools to 3 pools in order to reach the precipitation. The purpose of killing the pathogens in the feces of parasitic eggs and intestines is to make third pools of waste liquid a good quality fertilizer.

新鲜粪便由进粪口进入第一池，池内粪便开始发酵分解、因比重不同粪液可自然分为三层，上层为糊状粪皮，下层为块状或颗状粪渣，中层为比较澄清的粪液。在上层粪皮和下层粪渣中含细菌和寄生虫卵最多，中层含虫卵最少，初步发酵的中层粪液经过粪管溢流至第二池，而将大部分未经充分发酵的粪皮和粪渣阻留在第一池内继续发酵。流入第二他的粪液进一步发酵分解，虫卵继续下沉，病原体逐渐死亡，粪液得到进一步无害化，产生的粪皮和粪 厚度比第一池显著减少。流人第三池的粪液一般已经腐熟，其中病菌和寄生虫卵已基本杀灭。第三池功能主要起储存已基本无害化的粪液作用。

Fresh feces enter the first pool from the mouth of the dung. The feces in the pool begin to be fermented and decompose, which can be naturally divided into three layers. The upper layer is a paste dung, the lower layer is lump or dung, and the middle layer is a relatively clarified fecal fluid. The upper fecal and lower fecal slag contains the most bacteria and parasite eggs, and the middle layer contains the fewest eggs, and the primary fermented medium fecal fluid spillage through the fecal tube to second pools, while most of the unfermented fecal and fecal residues are kept in the first tank and continue to be fermented. In second, the fecal fluid was further decomposed, the eggs continued to sink, the pathogen gradually died, the fecal fluid was further harmless, and the fecal and fecal thickness decreased significantly than that in the first pool. In the third pools, the feces were generally decomposed, and the germs and parasitic eggs were basically destroyed. The third pool function mainly plays the role of storing basically harmless manure.

三格化粪池厕所的地下部分结构由便器、进粪管、过粪管、三格化粪池、盖板五部分组成。便器：由工厂加工生产或白行预制，便器采用直通式，与进粪管联接，也可使用水封式便器，不再安装近粪管。

The three part of the underground part of the septic tank toilet consists of five parts: toilet, excrement tube, excrement tube, three septic tank and cover plate. Toilets: factory production or white line prefabrication. The toilet can be directly connected to the excrement tube, and the water closet can also be used to stop the installation of near feces.

进粪管：塑料、铸铁、水泥管均可，内壁光滑、防止结粪、内径为10cm，长度为30-50cm。过粪管：以塑料管为好，直径为10-15cm，1-2池间的过粪管长约70-75cm，2-3池间的过粪管长约50一55Cm。

Feces: plastic, cast iron and cement pipes. The inner wall is smooth and prevents feces formation, the inner diameter is 10cm, and the length is 30-50cm. Over manure pipe: plastic pipe is good, diameter is 10-15cm, the 1-2 dung of the pond is about 70-75cm, and the feces of the 2-3 pools are about 50 55Cm.

三格池：用砖砌水泥粉壁面或水泥现浇，预制均可，以"目"字形为主要类型，若受地形限制，"品"字形、"丁"个型摆都也可。容积达到贮粪2个月为宜。三格池有效深度应不少于1 cm ，1至3格容积比例一般为2：1：3。

Three grid: brick cement powder wall surface or cement cast-in-place, prefabrication can be prefabricated with the "eye" shape as the main type, if the terrain is restricted, "product" shape, "Ding" type pendulum can also. It is suitable for 2 months of volume. The effective depth of the three cell pool should be not less than 1 cm, and the volume ratio of 1 to 3 grids is generally 2:1:3.

盖板：可自行预制，要做到既密闭，又便于清渣和取粪。

Cover plate: it can be prefabricated by itself, so that it is closed and easy to remove slag and take dung.
