Description
Technical field
The present invention relates to a kind of soil collecting experimental provision and experimental technique thereof, particularly relate to a kind of soil infiltration liquid and adopt
Collection experimental provision and experimental technique thereof.
Background technology
Along with improving constantly of the increasing of urban population, the increase of scale and living standards of the people, municipal solid waste
The generation amount of thing increases considerably, as house refuse, the mud of sewage treatment plant, steam power plant produce flyash, slag,
And desilting a large amount of bed muds etc. out in river course.These solid waste due to complicated component, wherein contain plurality of heavy metal,
The poisonous and harmful substances such as organic pollution, cause serious pollution to surrounding.All the time, municipal solid wastes
Processing disposal is all a great problem, and current topmost disposal options is still landfill.But fill the municipal solid stored up in a large number
Garbage not only occupies large-area land resource, and the percolating fluid that solid waste produces is to Soil Surrounding and subsoil water
Pollution the most increasingly come into one's own, particularly in rainfall and after rainfall, the solid waste such as rubbish, mud, river bottom mud
In a large amount of poisonous and harmful substances can be diffused in Soil Surrounding and body of groundwater along with rainfall infiltration.In recent years, due in agricultural
Chemical fertilizer, the use that exceeds standard of pesticide, the water pollution caused also is further exacerbated by.It is reported, have more than every year 15000000 t nitrogens from
Farmland flows in the water bodys such as river, lake, pond, causes the element total amount such as Water, phosphorus to sharply increase, water eutrophication
Change phenomenon again and again to occur.If owing to agricultural nonpoint source pollution owner is along with rainwash and soil infiltration entrance water body, therefore,
Understand Riparian Zone soil infiltration fluidity energy and pests occurrence rule is most important for water body controlling area-source pollution.Currently for soil,
In solid waste, the research of percolating fluid is mainly studied by laboratory simulation, and the research of field condition is less, and this is the most restricted
The reason that percolating fluid scene difficulty gathers in the solid waste such as soil, rubbish, mud.Existing field soil solution sampler
For positive and negative air-pressure sampler, owing to it uses pottery filter, cost is higher, and manual pneumatic pump is also relatively inaccessible to preferable effect
Really, be generally used for Experimental Base or have the experimental site of fixing artificial nurse, but for remoter agricultural watershed Riparian Zone,
Mud stores up the prosthetic nurse areas such as field does not still have application example.Therefore, a kind of cheap, soil that manipulation effect is good is invented
Earth percolating fluid harvester is to carry out original position soil, the matter of utmost importance of solid waste percolate performance study, for soil, river and ground
Lower water pollution is administered particularly significant.
