The transformation of the rural latrine is a good wedge machine for improving the rural living environment. The harmless sanitary latrine constructed by the transformation of the rural latrine has walls, roofs, doors, and standard toilets inside. It is clean and free of maggots and flies. It can basically achieve the non odor of the latrine environment. After the treatment of the feces in the septic tank, it can achieve the harmless feces, and the septic tank is impermeable, leakproof and airtight Cover.
For the reconstruction of rural toilets, brick and stone structured septic tanks should be adapted to local conditions. For the villages and scenic spots where rural residents live in scattered mountainous areas or where there is a lack of water, which are not easy to be covered by the sewage pipe network, we can reconstruct the toilets with the diversity of manure and urine and select the diversity of manure and urine equipment. The toilet with the diversity of manure and urine has the following remarkable characteristics:
1. It can save water resources, basically no water flushing, only a small amount of water is needed for urination, about 100-200ml each time, which is particularly valuable for water shortage areas;
2. It can effectively cut off the transmission path of intestinal infectious diseases and intestinal parasitic diseases, and kill pathogenic microorganisms from the source by dehydration and drying, which is more scientific;
3. Treat the excrement and urine as resources rather than waste, and recycle them to achieve ecological balance; at the same time, reduce the use of chemical fertilizer, produce multiple environmental protection effects, and promote sustainable development.
4. As there is no need for flushing, the excrement and urine diversity toilet will not pollute the surface water and groundwater, cut off the pollution of flushing water, and reduce the pressure of environmental treatment.
5. After reconstruction, the toilet has good airtightness, no flies and odors, and is easy to use and maintain. It has an immediate effect on improving the sanitary condition of the living environment, especially on fundamentally reducing the density of mosquitoes and flies.
