Description

A kind of Initial Runoff collection and purification reutilizing device
Technical field
The utility model relates to a kind of Initial Runoff collection and purification reclamation set, particularly relates to a kind of Initial Runoff collection and purification reutilizing device.
Background technology
China is one of country of water resource critical shortage, and water resources ownership per capita is only 1/4 of world's water resources ownership per capita, and China's distribution of water resources also exists serious uneven situation.In recent years, China's whole nation total supply is greatly about 5500 billion cubic meters, Water Consumption in Agriculture accounts for about 70% of whole water supply volume, wherein agricultural irrigation water amount accounts for 90% of agriculture total water consumption, therefore, should fully send out out and recycle every water resource, improve agricultural water cyclic utilization rate, improve agricultural irrigation water rate, reduce agricultural irrigation water total amount.In water resources development and utilization, rainwater is exactly by the high-quality water resource ignored for a long time.The total amount relative abundance of China's rainwater resource, annual nearly 6 tcms of amount of precipitation.Wherein have 3.2 tcms to penetrate in soil, evaporate after major part is absorbed by vegetation, fraction adds to underground water; And the rainwater of 2.8 other tcms is formed in surface runoff, have 2.7 tcms to pool the surface water such as river, lake, also having a small amount of becomes underground water.If Initial Runoff rainwater resources utilization is got up, will the total amount with water be greatly reduced, improve the utilization rate of water resource.
In addition, pollution of area source is also the problem of can not ignore.The agricultural run-off formed as rainfall causes agriculture N, P pollution of area source, and agricultural run-off causes body eutrophication after importing river.According to investigations, the loss of China agrochemical Middle nutrition element N, P is serious, and the average utilization of crops to N, P is only about 35%, and the remainder of about 2/3 enters water body by surface flow, soil filtration, causes the eutrophication of rivers and lakes water body.Therefore, initial stage of development discharge resources is recycled and is weakened pollution of area source problem simultaneously and have important practical usage.
Publication number is the patent of CN102786110 is that a kind of farmland nitrogen phosphorus pollution of area source controls, with the method recycled, to provide and utilize storing facilities of water and absorbing unit to control the method for farmland N, P pollution of area source.This invention has good purification, recycles the advantage of water resource.
But, this technology only achieves the object of farmland N, P element pollution control in accumulation facility, do not pay close attention to the purification not entering the agricultural run-off in accumulation pond, and when reuse rainwater, through the desorption of multilayer sorbing material, greatly reduce the concentration of N, P in recycle-water, not significantly will with recycling of water resource, and the limited need of this facility absorbing unit adsorption capacity amount are often safeguarded, engineering quantity is large, and cost is higher.The technology of publication number to be the patent of invention of CN101555071 be a kind of artificial swamp, provide the method utilizing buffer strip to control farmland, River Network N, P pollution of area source, this invention utilizes buffer strip areas, simple and practical the reaching of buffer strip plant subtracts dirty object, but does not but recycle rainwater resource.
Generally, for the control of same pollutant, prioritizing selection resource scheme, next is only resolution.Although N, P element in draining is pollutant to water body, be but required nutriment to vegetation.Research shows, N, P element in agricultural drain accounts for 2/3 of N, P total amount in fertilising, if by this part nutriment reuse to farmland, can be the fertilizer cost that peasant saves 2/3, has considerable economic implications.The beneficial effects of the utility model are i.e. accumulation rainfall Initial Runoffs, have purified to fail the rainwater of Collection utilization simultaneously, reduce the possibility that pollution of area source occurs.In addition, in this device, be provided with activating apparatus, can make to make it discharge the nutriment being conducive to vegetation growth during Rain water returning, real reaches saving fertilizer, the object of Rainwater Resources more.
