Description
Technical field
The invention belongs to water resource and environmental protection technical field, be specifically related to a kind of rainwash harvester and using method thereof.
Background technology
Along with the fast development of China's economic society, widespread pollution from the overuse of fertilizers and pesticides in rural area has become and has caused the especially principal element of water environment pollution of China's environmental pollution, and its a series of environment bringing, economic problems have caused very big concern both domestic and external.Research shows, in agricultural production, the loss of nitrogenous fertilizer, phosphate fertilizer is the topmost source of widespread pollution from the overuse of fertilizers and pesticides in rural area, in water body, the nitrogen of too high levels, phosphorus cause that algae and other planktonic organism breed rapidly, water body dissolved oxygen amount declines, fish and other biological mass mortality, serious pollution and destroyed aquatic ecosystem.Show according to national statistics office data, it is 5838.9 ten thousand t that China's agrochemical in 2012 is used pure amount, wherein nitrogenous fertilizer 2399.9 ten thousand t, phosphate fertilizer 828.6 ten thousand t.But the utilization ratio of chemical fertilizer is lower, nitrogenous fertilizer is generally lower than 30%, and phosphate fertilizer is generally lower than 15%.A large amount of unemployed nitrogen, phosphorus Nutrient rainwash and seepage are lost in river and lake, have polluted soil and water.
The rainwash that rainfall causes is the significant process of agricultural nonpoint source pollution, the nutrient such as nitrogen, phosphorus in farmland is one of main path of nitrogen and phosphorus loss with rainfall runoff to the migration of water body, is also the main cause that causes widespread pollution from the overuse of fertilizers and pesticides in rural area and then cause the surface water body eutrophication such as rivers and lakes.Therefore researcher attaches great importance to research and the monitoring to runoff both at home and abroad, and research and observation process must relate to the collection of runoff water sample, makes runoff sampling apparatus obtain application very widely.At present domestic the collection of runoff water sample is mostly undertaken by runoff collecting pit, runoff collecting pit can gather the runoff water sample in larger region, also the pollutant kind and the concentration that can Accurate Determining gather water sample, be applicable to long term monitoring, but also have its weak point simultaneously:
1) runoff collecting pit is generally brick mix structure, builds area large, causes investment amount large.
2) runoff collecting pit needs background soil to transform in process of construction, has destroyed the soil environment in region, is difficult to restore to the original state.
3) runoff collecting pit area is large, easily accumulates various impurity at the bottom of pond, needs frequent clean.
4) when run-off is larger in region, overflow phenomena easily occurs, underground water table rising simultaneously may be infiltrated in pond, causes runoff pollution species and the concentration of collecting to produce larger error.
5) runoff collecting pit lacks suitable pre-service, and all kinds of impurity easily adulterates.
6) runoff collecting pit position is fixed, and is not suitable for carrying out the runoff water collection of field short time.
A kind of simple and easy flow path surface of patent of invention of Inst. of Soil & Fertilizer, Guangdong Prov. Academy of Agricultural Science is measured and footpath flow liquid harvester (CN102346059), simplify many to specific run off collecting pit, more convenient to operate, but still can only gather the water sample of fixed position, can not carry, be not suitable for field multipoint acquisition.A kind of low interference sheet flow sampler of utility model patent (CN201607350) of Shenyang Inst. of Applied Ecology, Chinese Academy of Sciences's exploitation, simple in structure, be easy to carry, but lack suitable pre-service measure, easily make the water sample gathering be mixed with all kinds of impurity.
Therefore, design a kind of with low cost, be easy to carry, welding, the harvester that can quick and precisely collect runoff water sample in feature region are not very necessary.
Summary of the invention
The object of the invention is to overcome the weak point that above-mentioned prior art exists, a kind of rainwash harvester and using method thereof are provided, that this harvester has is simple in structure, with low cost, be easy to carry, little to environmental disruption, clean easily, do not have overflow and underground water to disturb, can carry out simple pretreated feature.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of rainwash harvester, formed by gatherer, aqueduct and Container, it is characterized in that, described gatherer is divided into impact damper and settling vessel by screen pack, the front apron height of described gatherer is lower than gatherer height, the slide damper that is connected with Diversion Plate is close at front apron back, gatherer backboard is provided with timer and rising pipe, rising pipe connects apopore, timer and rising pipe top are provided with weather shield, described Container top is provided with water inlet pipe, and aqueduct is by connecting rising pipe with water inlet pipe and then being connected gatherer and Container.
Described slide damper and Diversion Plate closely link together by welding, form right angle.
Described slide damper is embedded in filler rod, and filler rod inwall and slide damper sidewall are coarse flour milling, drives slide damper to slide by stretching Diversion Plate.
Described trap body, rising pipe, water inlet pipe are made up of transparent rigid plastic.Accumulator volumes is 30-100L, and rising pipe, water inlet pipe caliber are 5-15mm.
Described aqueduct is made up of plastic flexible pipe, and aqueduct caliber is 5-15mm.
