Description
Technical field
The present invention relates to the research field of restoration of the ecosystem, specifically a kind of experimental provision that is used for solid waste leachate collection under the simulating nature condition of raining.
Background technology
Develop rapidly in national economy, when living standards of the people improved energetically, a large amount of municipal solid wastes was produced and, a large amount of bed muds that desilting is come out in flyash, slag and the river course that produces like sludge of sewage treatment plants, cogeneration plant etc.These solid waste contain a large amount of poisonous and harmful substances because complicated component, and its treatment and disposal is become a great problem.Past, a large amount of municipal solid wastes was perhaps filled out the sea by landfill, burning.But As time goes on, the researchist finds to give up admittedly in filling out extra large process; Cause in the pollution, burning process of seawater and produce a large amount of toxic and harmful atmosphere pollutions; And with the solid waste landfill disposal, not only need large-area landfill place, and the percolate that solid waste produces can pollute peripheral soil and underground water; Secondary pollution is brought in the capital, can not reach desirable effect.In the last few years, solid waste was used for the farmland or soil improvement becomes focus, and also had to discover that in a large number it is a good recycling outlet that solid waste is used for the mine restoration of the ecosystem.Exist same problem solid waste in the process of recycling, also can leaching go out a large amount of poisonous and harmful substances then, peripheral soil and body of groundwater are caused serious threat.Therefore, become solid waste resource recovery for the research of solid waste leaching performance and utilize bottleneck problem in the process.
Research method in the past mainly is that solid waste is placed in the leaching post, adopts the dropper leaching of dripping then, and directly collects leachate.This method is the intensity of simulating nature rainfall really, and can't carry out the collection of leachate in the phytoremediation process in the leaching post; Also cause cross pollution easily with filtering again after the leachate collection, influence accuracy of experimental results.
Summary of the invention
The object of the present invention is to provide a kind of can the simulating nature rainfall intensity, can carry out many group contrast experiments' the experimental provision that the solid waste leachate is collected that is used for.
The objective of the invention is to realize like this: a kind of solid waste leachate is collected experimental provision, comprises water tank, isocon, leaching shower nozzle, solid waste experimental box, experiment table, leachate filtration unit and leachate adaptor.The lower end connection traffic meter of water tank, the flowmeter lower end links to each other with isocon via the master switch valve, and the isocon lower end is provided with several leaching pipes, and the leaching pipe links to each other with the leaching shower nozzle via the switch-dividing valve; Experiment table is placed in leaching shower nozzle below; Corresponding leaching nozzle position is provided with the leaching hole on experiment table; Place the solid waste experimental box above the leaching hole; The leachate filtration unit is installed below experiment table leaching hole, and leachate filtration unit lower end links to each other with the leachate adaptor through switch valve through plastic flexible pipe; The solid waste experimental box is the vinyon basin, and the bottom is provided with a plurality of uniform leachings hole, and leaching is laid gauze above the hole, places solid waste above the gauze, plants plant above the solid waste; Leachate filtration unit inside is provided with the bed filtration net, places filter membrane on the screen pack.
The artificial rainwater that at first will configure in the implementation process is placed in the water tank; Solid waste is placed in the solid waste experimental box; Be placed in the leachate filtration unit according to the screen pack of experiment needs, and the leachate adaptor is placed in leachate filtration unit bottom different filter openings.Open total Cistern valve then, according to the size of test needs, and open switch-dividing valve under the employed leaching shower nozzle separately, the beginning simulated rainfall through flowmeter control rainfall amount.Collect the leachate under the different time simultaneously, and change the leachate adaptor at any time.Leachate after the collection is directly measured.
The present invention has following advantage:
1. the leaching device is that total water tank, flowmeter, isocon and a plurality of leaching shower nozzle are formed, and this device can carry out many group contrast tests simultaneously, does not need independent regulating pondage, both saves time, and has reduced again that the people is the influence that causes in the experimentation.Be connected with flowmeter under total water tank of leaching device, through flowmeter controlled water flow size, the different rainfall intensities under can the simulating nature condition of raining.
2. the solid waste experimental box has the vinyon basin of even filter opening by the bottom and the filtration gauze of bottom is formed; Not only can be used for the independent leaching performance study of solid waste, also can carry out the leaching performance study of solid waste in the phytoremediation process.
3. be provided with the bed filtration film in the leachate filtration unit, according to the difference of requirement of experiment precision, the filtering membrane on the screen pack can be changed, and has saved the process of filtering after filtered fluid is collected in the past, has avoided the influence of cross pollution to experimental result.
