Problems solved by technology
In the past, the protection of drinking water safety in villages and towns was mostly based on environmental protection measures, such as the division of water source protection areas and the setting of signs for water source protection areas, etc., and the pollution prevention and control measures were insufficient.

Embodiment
[0104] Such as figure 1 As shown, a small and medium watershed drinking water source pollution prevention and control facility, including: ecological ridge 1, ecological interception ditch 2, ecological pond 3, ecological barrier corridor 4, main distribution channel 5, composite vertical flow ecological wetland 6 and river facilities 7.
[0105] The ecological ridge 1 is 300mm high, which can effectively prevent the surface runoff generated by 30-50mm rainfall, or reduce irrigation water in the early stage of fertilization in the paddy field to reduce the turbidity of the surface water, thereby reducing most of the farmland surface runoff, and plant alfalfa on both sides of the ridge Plants such as clover, clover, or soybeans form isolation zones, which can effectively block the loss of nitrogen and phosphorus nutrients and control the migration of residual pesticides to water bodies when surface runoff occurs.
[0106] Such as figure 1 , figure 2 As shown, the bottom of ...

The invention provides a medium and small watershed drinking water source pollution prevention and control facility and method, and relates to the field of water source land treatment. According to the medium and small watershed drinking water source pollution prevention and control facility, medium and small watersheds comprise farmlands and rivers serving as drinking water sources, and the prevention and control facility comprises ecological ridges, ecological interception ditches, ecological ponds, ecological barrier galleries and composite vertical flow ecological wetlands. A medium and small watershed drinking water source pollution prevention and control method is carried out by using the medium and small watershed drinking water source pollution prevention and control facility. According to the medium and small watershed drinking water source pollution prevention and control facility and method, pollutants such as organic matters, residual pesticides, nitrogen and phosphorus areeffectively intercepted and removed through multiple effects of physics, chemistry, microorganisms and plants, so that treated water reaches the standard of III-type water in the environmental quality standard of surface water.
Description
technical field [0001] The invention relates to the field of water source treatment, in particular to a facility and method for preventing and controlling pollution of drinking water sources in small and medium watersheds. Background technique [0002] Water is the source of life, the most active and most influential factor in the ecological environment system, and an important material and irreplaceable resource for social and economic development and human progress. With the development of the economy and the improvement of people's living standards, the people's requirements for the quality of life are getting higher and higher, but at the same time, due to economic development and over-exploitation of resources, the problem of drinking water sources and water resources in small and medium-sized river basins has been exhausted. These problems It is increasingly threatening the health of the people, especially in the vast rural areas where the income is relatively low and ...
