三格化粪池设计的基本原理
三格化粪池设计的基本原理是利用寄生虫卵的比重大于粪便尿混合液而产生的沉淀作用及粪便密闭厌氧发酵、液化、氨化、生物拮抗等原理除去和杀灭寄生虫卵及病菌，控制蚊蝇滋生，从而达到粪便无害化目的。
The basic principle of three septic tanks is the design of sedimentation and fecal anaerobic fermentation, liquefaction, ammoniation, biological antagonistic principle using parasitic eggs is greater than the proportion of feces urine mixture produced by removing and killing bacteria and parasite eggs, control the breeding of mosquitoes, so as to achieve the purpose of excrement.
为达到预期效果，在设计时应遵循以下原则。
In order to achieve the desired effect, the following principles should be followed in the design.
1、三个粪池的有效容积
The effective volume of 1 and three septic tanks
第一、二池的有效容积是根据粪便贮存发酵达到无害化所需的时间决定，根据实验,血吸虫卵、钩虫卵、伤寒杆菌、痢疾杆菌等在稀粪中存活时间在30天内。其计算方式为：第一、二池有效容积（立方米）=（人口数×30天×每人每天粪尿及冲水量3.5公斤）/1000。
The effective volume of the first, second pools is determined by the time required for the innocuous fermentation according to the stool storage and fermentation. According to the experiment, the survival time of schistosomiasis eggs, hookworm eggs, typhoid bacillus, dysentery bacilli and so on is within 30 days. The calculation method is: effective volume first, second pool (M3) = (population 30 days * * per person per day excrement and flushing water 3.5 kg) /1000.
第三池容积的大小视用肥周期而定，一般不小于第一和第二池之和。
The size of the third pool volume depends on the fertilizer cycle, which is generally not less than the sum of the first and second pools.
2、第一二池的容积比例
Volume ratio of 2, first two pools
为有利于虫卵沉淀，化粪池有效深度为1米，最少不少于0.9米，加上化粪池的上部空间，池深约为1.15米。第一池主要截留含虫卵较多的粪便、发酵分解。第二池处于相对静止状态，有利于漂浮在粪池的虫卵继续下沉。一般认为第一池与第二池的容积比为2：1较为适当。
In order to precipitate the eggs, the effective depth of the septic tank is 1 meters, at least not less than 0.9 meters, plus the upper space of the septic tank, and the depth of the pool is about 1.15 meters. The first pond mainly intercepted more feces and fermentation decomposition. The second pool is in a relatively static state, which helps the eggs that float in the cesspool continue to sink. It is generally considered that the volume ratio of the first and second pools is more appropriate for 2:1.
3、连通管位置设置
3. Position setting of connected pipe
三格池的格与格之间设有连通管，它关系到粪便流动方向，流程长短是否有利厌氧和能否有效阻滞粪便粪渣、以及保持一、二池的有效容积。目前较好的连通管设置应分别斜插安装在二堵隔墙上，其中第一池到第二池连通管下端（即粪池进口）位置在隔墙1/3处，上端(即粪液出口)距第二池顶10cm左右。第二池到第三池连通管下端(即粪池进口)位置在隔墙1/2处,上端距第三池顶10cm左右。
A communicating pipe is arranged between the three lattice lattice pool dative, which is related to the debris flow direction, flow length is favorable and anaerobic can effectively block dung slag, effective volume and maintain one or two pool. At present, a better connecting pipe should be installed on two separate walls respectively. The location of the first pool to the lower end of the second connected pipe (septic tank inlet) is located at the 1/3 of the partition wall, and the upper end (the outlet of the excrement liquid) is about second 10cm from the top of the pool. The lower end of the connecting pipe (the septic tank inlet) of the second pool to the third pool is located at the 1/2 of the partition wall, and the upper end is about 10cm at the top of the third pool.
三格化粪池厕所三个池的作用和功能可概述为一留、二酵、三贮。
The function and function of three tanks in three septic tank toilets can be summarized as one, two and three storage.
