Background technology

Domestic garbage burning electricity generation processing mode is one of main path of urban garbage disposal.China's urban life Rubbish water content is high, enter before stove burns in storage hole a large amount of stack after, can ferment generation Leachate site, Leachate site water quality complexity, has Machine substrate concentration is high, ammonia-nitrogen content is high, colourity is deep, stink is big, processes technology difficulty big.

In prior art, the processing mode of Leachate site mainly has two big classes: a class is through certain pretreatment by Leachate site After be directly discharged into municipal sewage plant and merge process；Another kind of is that Leachate site is carried out individual processing.Merging treatment needs Leachate site is pipelined to sewage treatment plant, and cost of transportation is high, economically unreasonable, and can be to sewage disposal factory and office Reason system impacts；Leachate site is carried out individual processing, existing leachate processing technique method, has a various ways, but Efficiency, effect and cost of investment aspect are the most less desirable.

Summary of the invention

For defect of the prior art, the present invention provides a kind of Calx karst region Leachate site regulator control system, with the short time In Leachate site carried out after-treatment, and the Leachate site processed is entered in subsoil water, it is simple to recycling.

The Calx karst region Leachate site regulator control system that the present invention provides, including cylindrical bilge well, and is centered around described The filtration channel of the annular of bilge well bottom outside, this filtration channel connects bottom described bilge well；Described filtration channel Supported by multiple gripper shoes between end face and bottom surface；Wall casing, described wall casing and bilge well well it is provided with in described bilge well Using cement mortar to recharge between body, bottom described bilge well, the communicating position with filtration channel inner circumferential is provided with water-permeable pipe, oozes drip Liquid enters filtration channel via described water-permeable pipe tube wall；The bottom surface coating cement of described bilge well；Fill in described filtration channel Cobble and sandstone, and in filtration channel, it is provided with filter, this filter is set in outside described water-permeable pipe.

In the present invention, the geologic structure of Calx karst region is followed successively by silty clay, argillaceous siltstoue and limestone from top to bottom, Wherein silty clay is loosely organized, and argillaceous siltstoue compact structure is the hardest, and the stalagmite of limestone, clint and solution cavity are more Grow.Therefore, bilge well being arranged on farinose argillic horizon and argillaceous siltstoue layer, shaft bottom contacts with ash rock stratum, and this bilge well is used In accommodating the Leachate site through pretreatment, being surrounded with the filtration channel of annular in the bottom of this bilge well, this filtration channel is with dirty The bottom connection of well, and the two is coaxially arranged, the position that the inner circumferential of this filtration channel connects with bilge well is provided with water-permeable pipe, Leachate site in bilge well enters in filtration channel via the tube wall of water-permeable pipe, and being set in the filter outside water-permeable pipe can be by Float in Leachate site filters out, and due to the Shi Hui rock stratum, bottom surface of filtration channel, its solution cavity physically well develops, and water penetration is preferable, Therefore Leachate site can directly permeate the ground in solution cavity after filtering, and subsoil water converges, it is simple to recycling.Wherein, bilge well Inside it is provided with wall casing, and uses cement mortar to recharge between wall casing and well bore, the stability of bilge well can be increased, prevent well Body caves in, the bottom surface coating cement of bilge well, can prevent undressed Leachate site from permeating the ground, cause underground water pollution.? Between end face and the bottom surface of filtration channel, gripper shoe is set, is possible to prevent filtration channel to cave in, fill in filtration channel simultaneously Cobble and sandstone, can improve the intensity of filtration channel further, and by the porous space adsorbing contaminant of sandstone surface, it is right to play The effect that in filtration channel, water body purifies further.

Preferably, being also arranged with the first absorption looped network outside described water-permeable pipe, this first absorption looped network includes the first micropore Filter screen, fills diatomite particle in described first micro-strainer.Diatomite particle can be by the fine impurities in Leachate site, greasy dirt Adsorb with chemical substance, Leachate site is purified, and the first micro-strainer can play the effect accommodating diatomite particle, side Just diatomite particle periodic replacement, prevents its adsorption function from weakening.

Preferably, being also arranged with the second absorption looped network outside described water-permeable pipe, this second absorption looped network includes the second micropore Filter screen, fills activated carbon granule in described second micro-strainer.Activated carbon granule can carry out physical absorption to Leachate site, to dispel Except the stink of Leachate site, Leachate site is purified further, and the second micro-strainer can play and accommodate activated carbon granule Effect, facilitates activated carbon granule to regularly replace, prevents its adsorption function from weakening.

Preferably, described filter, the first absorption looped network and the second absorption looped network three fit the most successively.Ooze drip After liquid enters filtration channel, first by filter, large granular impurity therein is dispelled, subsequently into the first absorption looped network, diatom The absorption of fine impurities therein, greasy dirt and chemical substance can be dispelled by soil particle, finally enters the second absorption looped network, activated carbon Granule can carry out physical absorption to it, is dispelled by its stink, the most incremental, so that the clean-up effect of Leachate site is more For significantly.

Preferably, described gripper shoe is 8 that circumference is uniform, to ensure the structural strength of filtration channel.

Preferably, described each gripper shoe includes the steel plate of two pieces of vertical directions, is watered by cement between described two block plates Build fixing.Use this simple supporting plate structure, not only can meet the requirement of strength of filtration channel, it is also possible to save into This.

Preferably, described first micro-strainer and the second micro-strainer are stainless steel.The intensity of stainless steel is relatively Height, and stainless steel has preferable corrosion resistance, goes for water source environment complicated in leachate treatment, extends Its service life.
