Method for preventing and treating regional area pollution of farmland farming ditch and pond regions

Abstract

The invention relates to a method for preventing and treating the regional area pollution of farmland farming ditch and pond regions, and belongs to the field of environmental governance. The method is characterized in that a plurality of farmland ditches directly discharging into the main water discharge ditch are selected to carry out farmland ecological ditch construction, wherein the construction is divided into ditch transformation and plant construction; a pond at any corner position in the same farmland region is selected and transformed into the ecological pond so as to make the water discharged from the farmland be directly discharged into the pond, and one side of the pond is provided with the water discharge port; and the heavy pollution section in the main water discharge ditch and the water discharge portion section for making the sub-water discharge ditch discharge into the main water discharge ditch are provided with filtration boxes for filtering the farmland wastewater, and the filtration boxes are fixed on the bottom of the ditch. According to the present invention, the existing farmland water discharge facilities and the ponds are utilized, the effective pollution preventing and reducing measures are transformed and constructed, the nitrogen content and the phosphorus content in the water discharged from the farmland are significantly reduced, the pollution of the farmland regional area pollution on the river channels and the lakes can be effectively controlled, the eutrophication risk can be reduced, the good ecological cycle system is formed while the regional water recycling is achieved, and the economic benefits of the farmland are improved.

Description

technical field [0001] The invention belongs to the field of environmental management, and in particular relates to a method for preventing and controlling regional area pollution in ditches and ponds of farmland planting. Background technique [0002] Farmland regional area pollution refers to the formation of nutrients such as nitrogen and phosphorus, pesticides, and other organic or inorganic pollutants through the surface runoff and seepage of farmland along with precipitation or irrigation during farmland production activities. Environmental pollution mainly includes chemical fertilizer pollution, pesticide pollution, livestock and poultry manure pollution, etc. With the continuous increase of fertilizer consumption in the process of farmland planting, the nitrogen and phosphorus content and loss of nitrogen and phosphorus in farmland soil continue to increase, resulting in increased environmental pollution of farmland soil and surrounding water bodies.

Problems solved by technology

In recent years, scholars at home and abroad have done more research on the ecological interception technology of farmland non-point source pollution, and related technologies have been popularized and applied to a certain extent, but there are few researches and applications on the ecological interception technology system of large-scale farmland or large-scale planting bases.
