Technical Field
The invention relates to the field of efficient utilization of water resources and water environment protection, in particular to a series connection type water and fertilizer resource collecting and utilizing system for greenbelts and farmlands.
Background
The occupation level of water resources per capita in China is relatively low, and in recent years, a large number of cities generally face double tests of serious resource type water shortage and water quality type water shortage. Especially for loess plateau areas in northern China, most areas are dry and have little rain, and due to unique climatic and geological characteristics, a compact loess surface layer is easily formed on the ground, and the infiltration capacity is extremely poor. When the soil bodies are used for greening and planting and ploughing, due to the influence of a surface structure, precipitation cannot timely infiltrate down, water bodies accumulated on the surface of a soil layer can only flow away as runoff, or later evaporation is changed into water vapor, and the water vapor is difficult to be utilized and absorbed by vegetation. The farmland can also suffer from the problem in the irrigation process, so that the irrigation efficiency is low, and the water loss is large. Aiming at the problem, redundant rainwater and irrigation water need to be collected on site, runoff and evaporation are reduced, and water resource supply of vegetation is guaranteed.
The surface runoff of the green land and the farmland carries more redundant fertilizers and nutrients, so that non-point source pollution is formed, the water is polluted after the non-point source pollution is converged into the water, and the polluted water needs to be treated at high cost for a long time. There is therefore a need for relatively economically sound engineering measures to achieve contaminant control at the source. To greenery patches and farmland, unnecessary rich water and surface runoff are collected through the regulation and storage device to can slow release, not only can save water resource and fertilizer, can also effectively reduce non-point source and pollute. Has obvious economic benefit and social benefit.
Although the rainwater storage tank in the sponge urban facility can collect rainwater to reduce water environment pollution, the rainwater storage tank is a terminal measure and can only play a role by needing a large occupied area and a long-distance rainwater pipeline, and sewage in a road surface, a green land and a rainwater pipeline network is collected together by the measures and is difficult to directly utilize or discharge without treatment.
