Description
Technical field
The utility model relates to solid waste and administers field, particularly a kind of leachate recirculation device for the aerobic reparation of refuse landfill.
Background technology
Along with the raising of people's living standard, particularly the domestic refuse generation is increasing for rubbish, and the refuse pollution problem becomes increasingly conspicuous.In the main domestic rubbish disposal mode of China, the landfill disposal amount is 85%, and the burning disposal amount is 10%, and the compost treatment amount is 5%.As can be seen, in the quite a long time, garbage loading embeading is handled the main processing mode that remains China's domestic refuse.
Refuse landfill has taken the arable land of a large amount of preciousnesses as the place of landfill waste, in the slow degradation process of organism, produces a large amount of percolates in the while rubbish, and this percolate can severe contamination refuse landfill periphery groundwater environment.Traditionally, refuse landfill reaches innoxious stabilization fully, generally needs the time more than 50 years.Therefore the pollution feature of refuse landfill is with long-term existence.
Developed countries has carried out the research of refuse landfill fast and harmless stabilization, some achievements have been obtained, it is generally acknowledged, adopt the aerobic recovery technique of refuse landfill, can accelerate organic degraded in the rubbish, the stabilization period of refuse landfill landfill waste was shortened to about 2 to 3 years from 50 years.Therefore the garbage aerobic recovery technique has broad application prospects.But at the early-stage in the aerobic recovery technique research of China's refuse landfill, some colleges and universities and R﹠D institution have carried out correlative study and experiment, but technology all not mature enough, fail to drop into commercial applications.
This external China, the percolate that domestic refuse produces, the necessary collection and treatment of national regulation, but consumer waste infiltration liquid complex treatment process, technology is ripe not enough, and investment is high.
Summary of the invention
At above-mentioned deficiency of the prior art, the purpose of this utility model provides a kind of leachate recirculation device for the aerobic reparation of refuse landfill.Utilizing aerobic recovery technique to repair in the refuse landfill process, percolate is recharged in the refuse landfill.Take full advantage of various microorganisms and moisture in the percolate on the one hand, accelerate organic aerobic degradation in the rubbish, accelerate the quick repair process of refuse landfill; On the other hand, also can save the percolate disposal plant of general refuse landfill, save facility investment and occupation of land greatly.
In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:
A kind of leachate recirculation device for the aerobic reparation of refuse landfill, its constructional feature is that it comprises pumping pipe, drawing liquid blower fan, container for storing liquid, fluid injection blower fan, liquid injection tube, temperature sensor, humidity sensor, gas composition sensor and the control device that connects successively.
The percolate that refuse landfill produces by going deep into the pumping pipe of its bottom, is pumped in the container for storing liquid by the drawing liquid blower fan.The fluid injection blower fan is extracted the percolate in the container for storing liquid out, enters liquid injection tube through spout, is diffused into refuse landfill top by the liquid injection tube bottom.Be arranged at temperature sensor, humidity sensor and gas composition sensor in the refuse landfill, the refuse landfill significant parameter is fed back to control device, switch and the rotating speed of control device control fluid injection blower fan,, promote the aerobic repair process of refuse landfill.
Compared with the prior art, advantage of the present utility model is:
(1) because the aerobic reparation of refuse landfill needs the participation of microorganism and moisture, though and percolate contains these materials, but be deposited in the refuse landfill bottom, by drawing liquid liquid blower fan and fluid injection blower fan percolate is injected into the refuse landfill top, can be conducive to organism and realize quick aerobic degradation, shorten the required time of refuse landfill stabilization greatly.
(2) save the percolate disposal plant of general refuse landfill, reduce investment outlay greatly and occupation area of equipment.
(3) collect key parameters such as refuse landfill temperature, humidity, gaseous constituent by sensor, control device is controlled the amount of recharging of percolate automatically according to parameter, makes the organism aerobic degradation, is in the optimum response interval.
(4) by kind of the leachate recirculation device for the aerobic reparation of refuse landfill, to solving China's refuse landfill land occupation and the problem of polluting surrounding enviroment, has strategic importance.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
