Now many rural residents will jointly raise funds to build biogas digesters in their villages and discharge pollutants. In addition to solving the pollution problem in rural areas, they also have certain use value. In addition, China now has several thousand yuan to subsidize the construction of biogas digesters in rural areas. The construction of rural biogas digesters can not only improve the living environment, but also contribute to the green cycle of agriculture. It can save energy to a great extent and is a good choice. If conditions permit, it is best to build a sewer in the house to ensure the convenience of life in the future.
Rural kitchen sewage discharge: Generally speaking, rural residents wash vegetables and dishes in the well at their doorstep. The washed water fell directly to the ground. Poultry such as chickens and ducks will eat rice and vegetable leaves in sewage. After sewage is poured into the ground, part of it will evaporate and the other part will seep into the ground. Because most of the countryside is muddy, the sewage directly poured on the ground will not stink because of accumulation. The soil will directly absorb the remaining sewage, and underground microorganisms will multiply. Rural domestic waste can also be decomposed.
Rural toilet sewage discharge: rural residents will dig a septic tank around the toilet. Sewage stored in fertilizer boxes can be used for vegetable gardens or discharged into small ponds or dry toilets in uninhabited areas and rural areas.
Rural rainwater drainage: There are many lakes, rivers and ponds in rural areas, and there are many drainage ditches in rural areas. In addition, the ground in rural areas is not paved with cement. So when it rains, the rainwater will flow directly into lakes, ponds and rivers along the drainage ditch, and part of it will be absorbed by the soil. Therefore, there is no need to worry about rainwater discharge in rural areas.
