Rural sewage treatment protects the ecological environment of rural areas Rural sewage treatment sewage discharge dispersion, disorder, wide range, many sources, high concentration, poor infrastructure, rain pollution is not separated, pipe network is not perfect, poor sanitary conditions, water through many, sewage no treatment arbitrary discharge, or only through septic tank treatment on the straight row, poor management level, lack of professionals in the team, relative to urban domestic sewage,
Rural domestic sewage has the characteristics of scattered dispersion, relatively high concentration of pollutants, large difference in water quantity and so on. China's rural population is large, the amount of domestic sewage discharge is large, because it can not be effectively treated, so it causes some damage to the environment.
Due to insufficient investment in sewage treatment funds, farmers do not have enough awareness of environmental protection, most villages do not have sewage treatment equipment, domestic sewage directly discharged into the environment, seriously affecting the rural ecological environment, farmers ' drinking water safety can not be guaranteed.
1. Current status of rural sewage treatment With the continuous improvement of rural living standards, the discharge of rural domestic sewage has gradually increased, the rural ecological environment has been seriously damaged, the health of farmers has posed a great threat, the rural environment is worrying. The survey report shows that most villages in our country lack drainage equipment and discharge sewage directly without treatment. 89% of the village's household waste is discarded directly before and after the house, in the village of the pond, and no one in the village to dispose of the rubbish.
The arbitrary discharge of domestic sewage not only causes damage to rivers and ponds, but also pollutes the living environment of villagers and seriously affects the physical health of villagers. Rural domestic sewage mainly includes bathing, kitchen, flushing and the fecal water of farmers ' farmed livestock. The sewage treatment rate in rural areas is not high, the distribution of sewage is scattered, there is no rule of water discharge, the content of organic matter in sewage is high, the content of harmful substances such as heavy metals is not high .
The rural population lives more dispersed, but because the residents have a very similar law of life, which causes the rural domestic sewage discharge flow during the day than sooner or later, the night drainage is not small, the number changes greatly.
2. Problems existing in rural sewage treatment in China The cause of the problem of rural sewage is becoming more and more serious, not only from one aspect, but also from the common influence of many factors.
The following is a separate discussion from the following three aspects, that is, the prevention of sewage awareness is weak, the management of sewage treatment regulations are missing and the sewage treatment problem is underfunded. The problem of weak consciousness in the problem of rural sewage treatment includes two aspects, one is that the villagers have a weak awareness of the problem of preventing sewage pollution, and the other is that the government has a weak awareness of the problem of sewage treatment. Villagers ' awareness of the weak performance in the toilet treatment of sewage, domestic sewage and other random discharge on the ground, and not through specially treated pipes discharged to a fixed location, of course, this is closely related to the lack of facilities, but from the results of the survey, villagers in the rural sewage treatment concept is very shallow, even do not think that sewage should be treated before discharge
Because the way they have handled it over the years has been to discharge sewage directly on the ground without a sense of preventing sewage pollution. Rural sewage treatment Rural sewage awareness of the weak table now, there is no real implementation of the relevant regulations to each rural point, or even improve the idea of implementing such regulations, the rural sewage pollution problem is delayed and more serious.
