Village cadres study how to solve this problem together. After many discussions, the idea of using the "east wind" to improve the living environment was put forward, and the dry toilets were cleaned up, and all the dry toilets were changed into flush toilets, and high-standard sanitary toilets and landscape belts were built along the road to facilitate the laying of tap water pipes and sewage pipe networks, thus improving the village appearance in an all-round way.
First, the sewage is discharged to the first compartment through the water inlet. In the first grid, solid substances and parasite eggs with high specific gravity are precipitated, and anaerobic bacteria in the pool water are used to start early fermentation and decomposition. The sewage treated in the first grid can be divided into three layers: pasty dung skin, dung cleaning liquid and solid dung residue.
After the initial decomposition, fecal liquid flows into the second cell, while floating fecal skin and deposited fecal residue remain in the first cell to continue fermentation. In the second compartment, the manure continued to ferment and decompose, the eggs continued to sink, the pathogenic bacteria gradually died, the manure was further harmless, and the thickness of manure skin and manure residue produced was significantly reduced compared with that in the first compartment.
