Description
Technical field
The utility model relates to the garbage disposal field, be specifically related to a kind of energy real-time online and detect parameters such as junk-heap body interior temperature, humidity, gas componant and content, pressure and surface subsidence, slope displacement, by gas injection well, extraction well, fluid injection well, drawing liquid well, the gas injection of monitor well comprehensive regulation, bleed, operational factor such as fluid injection, drawing liquid, guarantee that aerobic reaction carries out in the junk-heap body under optimum condition, reduce danger such as blast, fire, landslide, secondary pollution, guarantee to administer the effectively aerobic improvement well pattern of refuse landfill of operation of process safety.
Background technology
According to nation-building portion statistics, China's domestic waste generation in 2005 is 1.56 hundred million tons.In these house refuses that produce, only have 44% to enter sanitary filling field (controlled landfill), other has 29% by simple and easy landfill, and 20% is arbitrarily abandoned and is toppled over, and adds up to 49% rubbish to be in non-control landfill (stacking) state fully.By the national environmental protection office data, solid waste is stored up occupation of land and is ruined 2,000,000 mu in field.
In November, 2006, " Beijing's household refuse landfill sites pollution risk appraisal report " pointed out: Beijing has 490 places, soot (containing 458 places, informal soot), 126 places that pollution risk is big, 105 places that pollution risk is medium.According to statistics, the existing informal refuse landfill gross area in Beijing surpasses 20,000 mu, and the rubbish storage amount is about 8,000 ten thousand tons.
Obviously, a large amount of historical informal (non-health) refuse landfills that form take a large amount of land resources, owing to there are not pollution control measures such as underground water and atmosphere, degraded will cause long-term harm and pollution to surrounding environment under nature.The foul odour of methane gas not only influences environment and health, and may produce fire hazard.The generation of percolate with converge, also severe contamination the periphery soil and underground water.Usually, refuse landfill reaches stabilisation fully needs the time in 50 to 100 years, so the pollution feature of junk-heap body is with long-term existence.
At the problems referred to above, the eighties in 20th century, the U.S., Britain, Canada, Australia, Germany and Japan etc. carried out the research of bioreactor landfill in succession.Wherein, aerobe reactor landfill technology is by the purpose control device is arranged, for aerobic microbiological in the rubbish provides growing environment preferably, quickened organic degraded in the landfill waste, improved the stabilization procedures of landfill waste, make the stabilization period of traditional landfill waste foreshorten to 2-3 from 50-100, thereby long-term supervision and maintenance after having avoided closing, make landfill yard have the rubbish of storing simultaneously, cut off a plurality of functions such as pollution, biodegradation and resource recovery, and guarantee that landfill yard coordinates mutually with surrounding environment as early as possible.
The aerobic improvement technology of landfill yard be with percolate, other liquid and air etc. according to refuses biodegradation needs in the field, be added to landfill yard by a kind of controllable mode.By parameters such as the temperature in the control adjustment junk-heap body, humidity, gas contents garbage organism is degraded fast, reach stabilization of state (degradation speed is 30 times of natural degradation) rapidly.The essential characteristic of its stabilisation is: the degradable organic component of rubbish reaches that mineralising, percolate not treatedly can discharge, waste layer does not have substantially that gas produces, surface, place natural subsidence stops.
When existing aerobic improvement technology enforcement well location was arranged, some just designed the gas injection well to junk-heap body, not the active air extractor; The landfill waste degree of depth is not considered in some gas injection well setting, only in bottom position gas injection, inefficiency; Some is provided with gas injection, air extractor, does not guarantee aerobic reaction water injection well efficiently but be provided with; Independent, dispersion that some parameter monitoring well is provided with does not realize the comprehensive effectively detection to parameters in the junk-heap body; Cause in the governance process, gas, liquid supply can't satisfy the demands, there is not the measure of humiture in the better controlled heap body, governance process is to carry out under the situation of fuzzy, poor efficiency, regulation effect is poor, and be easy to generate secondary pollutions such as aqueous vapor, also may blast simultaneously, hazards such as fire, landslide.
