格式化粪池的基本原理
格式化粪池的基本原理
The basic principle of formatting septic tank
三格式化粪池是由三个相互连通的密封粪池组成，粪便由进粪管进入第一池依此顺流至第三池，其各池的主要原理：
The three format septic tank is composed of three interconnected sealed septic tanks. The feces enter the first tank through the fecal inlet pipe, and then flow to the third tank
第一池：主要截留含虫卵较多的粪便，粪便经发酵分解，松散的粪块因发酵膨胀而浮升，比重大的下沉，因而形成上浮的粪皮、中层的粪液和下沉的粪渣。利用寄生虫的比重大于粪尿混合液的原理使其自然沉降于化粪池底部。利用粪液的浸泡和翻动化解粪块使其液化并截留粪渣于池底。厌氧发酵：化粪池的密闭厌氧环境，可以分解蛋白性有机物，并产生氨等物质，这些物质具有杀灭寄生虫卵及病菌的作用。
The first pool: it mainly intercepts the feces containing more eggs. After fermentation, the loose feces will float up due to the expansion of fermentation, which will cause a significant subsidence, thus forming the floating dung skin, the middle layer of fecal liquid and the sinking fecal residue. Based on the principle that the specific gravity of parasites is greater than that of manure and urine mixture, the parasite can settle naturally at the bottom of the septic tank. By soaking and turning the fecal liquid, the fecal block is dissolved to liquefy and retain the fecal residue at the bottom of the tank. Anaerobic fermentation: the closed anaerobic environment of septic tank can decompose protein organic matter and produce ammonia and other substances, which can kill parasitic eggs and bacteria.
第二池：起进一步发酵、沉淀作用，与第一池相比，第二池的粪皮和粪渣的数量减少，因此发酵分解的程度较低，由于没有新粪便的进入，粪液处于比较静止状态，这有利于漂浮在粪池中的虫卵继续下沉。
The second tank: it can further ferment and precipitate. Compared with the first tank, the amount of fecal skin and fecal residue in the second tank is reduced, so the degree of fermentation decomposition is low. As there is no new feces entering, the fecal liquid is in a relatively static state, which is conducive to the continued sinking of eggs floating in the septic tank.
第三池：主要起储存粪液的作用。经前二格处理的粪液进入第三池，基本上已经不含寄生虫卵和病原微生物，达到了粪便无害化要求，可以供农田直接施肥。
The third pool: mainly for storing fecal liquid. The fecal liquid treated by the first two compartments enters into the third pool, which basically does not contain parasitic eggs and pathogenic microorganisms. It meets the requirements of harmless feces and can be used for direct fertilization in farmland.
