At present, the industry has a good understanding of urban environmental governance. The world and China have sufficient experience and models for reference. The water system of cities in China includes water sources, water intake, drainage, governance systems, natural water bodies, and urban water environmental protection. There are also clear ideas. But in the countryside, the situation has completely changed. For example, in terms of water sources, there are more ways to obtain water than in cities. People can directly use the surrounding water sources, groundwater or water from river networks as drinking water sources; in terms of drainage, rural areas are not like cities that have strict sewage treatment standards. Plant and pipe network. So the rural water environment system seems simple, but it contains endless complexity.
Planting, breeding and garbage are important factors of rural water pollution.
The drinking water source of the village may be polluted by farmland, livestock and poultry breeding, garbage or toilet penetration, and the rural water environment may be polluted by rural domestic garbage, fertilizers and pesticides from agricultural non-point sources, and antibiotics from livestock and poultry breeding. . Therefore, rural environmental issues are not limited to rural areas, but are also related to everyone and the water environment management of the river basin.
It’s not enough to consider only water in rural water environment. Garbage and sanitation are also important factors that affect the water environment. Rural water environment governance is a comprehensive and systematic project. When talking about water, there is no way out. We must pay attention to its comprehensiveness. And practicality. For example, sewage and garbage must be treated at the same time; livestock and poultry breeding and agricultural non-point source pollution should be comprehensively controlled; water sources and water supply quality should be improved synergistically; standards and control should be adapted to local conditions.
Therefore, in the future, we should not only focus on treatment and disposal, but should also focus on pollution control and resource utilization. We must consider the rural water environment from the perspective of comprehensive management, including waste, sanitation, livestock and poultry breeding, agriculture, and non-point sources. Wait, this is the comprehensive way of thinking about managing the rural water environment. Water, soil, gas, and solid waste should be treated together, and the discharge, intermediate disposal, conversion, and various sources involved should also be controlled in a multi-process and multi-source cycle. Finally, it is also indispensable that multiple measures such as technology, engineering, policy, and management are effective.
