玻璃钢化粪池的发酵过程分为：过滤沉淀-厌氧发酵-固体物分解-粪液排放。

The fermentation process of FRP septic tank can be divided into filtration sedimentation - Anaerobic Fermentation - solid decomposition - excrement discharge.

一般来说，我们把一个大的玻璃钢化粪池池子分成三格或四格，三格叫三级化粪池，四格叫四级化粪池。

Generally speaking, we divide a large FRP septic tank into three or four compartments. Three compartments are called three-level septic tank and four are called four-level septic tank.

污水由进水口排到靠前格，在靠前格里比重较大的固体物及寄生虫卵等物沉淀下来，开始初步的发酵分解，玻璃钢化粪池在上层粪皮和下层粪渣中含细菌和寄生虫卵比较多，中层含虫卵比较少，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靠前池内继续发酵。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靠前池显著减少。经靠前格处理过的污水可分为三层：糊状粪皮、比较澄清的粪液、和固体状的粪渣。

Sewage is first discharged from the water intake to the first tank. Solids and parasite eggs with a larger proportion in the first grid are precipitated, and initial fermentation decomposition is started. The fiberglass reinforced plastic septic tank contains the most bacteria and parasite eggs in the upper layer of excrement and the lower layer of excrement, while the middle layer contains the least worm eggs. The middle layer of the initial fermentation overflows to the second tank through the excrement tube, and most of the excrement is not fully fermented. Fecal skins and residues were blocked in the first pond to continue fermentation. The feces flowed into the second pool were further fermented and decomposed, the eggs continued to sink, the pathogens gradually died, and the feces were further harmless, resulting in a significantly reduced thickness of the feces and the feces than in the first pool. The wastewater treated in the first case can be divided into three layers: pasty dung, relatively clarified dung and solid dung residue.

经过初步分解的粪液流入第二格，而漂浮在上面的粪皮和沉积在下面的粪渣则留在靠前格继续发酵。在第二格中，粪液继续发酵分解，虫卵继续下沉，病原体逐渐死亡，粪液得到进一步无害化，产生的粪皮和粪渣厚度比靠前格显著减少。

After the initial decomposition, the excrement flows into the second compartment, while the floating excrement and the sediment deposited below remain in the first compartment and continue to ferment. In the second case, the feces continued to ferment and decompose, the eggs continued to sink, the pathogens gradually died, the feces were further harmless, and the thickness of the feces and residues produced was significantly lower than that in the first case.

流人第三格的粪液一般已经腐熟，其中病菌和寄生虫卵已基本杀灭。第三格功能主要起暂时储存已基本无害的粪液作用。

The feces flowing into the third compartment are generally ripe, and pathogens and parasite eggs have been basically killed. The third function is mainly to temporarily store the basically harmless excrement.
