technical field

The utility model relates to the technical field of agricultural waste water recycling and treatment, in particular to an automatic control farmland runoff collection and irrigation device.

Background technique

With the effective control of point source pollution such as industrial wastewater and urban domestic sewage, the harm of non-point source pollution to the water environment has attracted widespread attention, and research on non-point source pollution has become an active field of international environmental research. Agricultural non-point source pollution (ANPSP) refers to nutrients such as nitrogen and phosphorus, pesticides and other organic or inorganic pollutants produced in agricultural production activities. Drainage and underground seepage into surface water and groundwater, causing pollution to the water environment. At present, relatively mature ecological projects such as artificial wetlands, pre-reservoirs, vegetation buffer zones, water and land interlaced zones, soil and water conservation and agricultural ecological engineering are mainly used at home and abroad to control agricultural non-point source pollution. The removal efficiency of P can reach 50-70%, but such projects do not consider the resource utilization of rainfall runoff and its lost pollutants. Preliminary statistics show that in 2015, the national annual rainfall was about 6 trillion m ³ , of which 2.7 trillion m ³ entered rivers and lakes through surface runoff, forming surface runoff. If the resource utilization of rainwater, runoff and runoff pollutants is fully considered, the efficiency of agricultural water use and the removal of agricultural N and P will be greatly improved.

At present, there are many technologies and methods for agricultural non-point source pollution treatment, but each has its own advantages. The invention patent with the publication number CN101555071 is a technology of artificial wetland. The invention utilizes the degrading effect of plants in the buffer zone area to achieve the purpose of pollution reduction simply and practically, but it does not recycle rainwater resources. The patent with the publication number of CN102786110 is a method for the control and recycling of non-point source pollution of nitrogen and phosphorus in farmland. The invention has the advantages of good purification effect, recycling water resources, etc., but does not pay attention to the purification of farmland runoff that does not enter the storage tank and The adsorption unit of this facility has limited adsorption capacity, large engineering volume and high cost.
