Description
Technical field
The present invention relates to a kind for the treatment of process of refuse landfill, particularly a kind of inside Air Exposure technique of townm refuse landfill yard.
Background technology
Be mainly underground impervious wall for traditional pollution control scheme of old landfill yard for a long time to close and the collection disposal etc. of landfill gas and percolate, the refuse landfill also had adopts the mode of resettlement.
Cut-pff wall is closed: around old landfill yard, and build cut-pff wall by methods such as cement grouts, the degree of depth reaches underground water barrier, is carried out the diffusion of isolated percolate, by " enclosing, envelope, stifled " by Environmental capacity in landfill yard.The shortcoming of this scheme is can only passive shutoff, thoroughly can not effectively solve leachate contamination problem.
Carry out collection to landfill gas and percolate respectively to dispose.Such as dig a well on landfill heap body, lay gas collection pipes, collect solid waste gas, burning or generating process; Leachate collection well is set, percolate extracting is derived, processes.These measures are for a lot of construction initial stage with regard to the old landfill yard without any anti pollution facilities, and the collection of landfill gas and percolate is a difficult problem, are therefore difficult to effectively realize effective collection truly and process.
Landfill yard resettlement is disposed this scheme and is also faced a lot of practical problems, such as how be still in the landfill yard in anaerobism intense reaction period to those inside and carry out excavation carrying work, moving a still unstabilized landfill yard in inside is an engineering project being difficult to realize.The process of resettlement may produce serious secondary pollution, and the expense of resettlement is huge.The rubbish of resettlement still will find new storing place, and the selection in place is also a very complicated engineering.
Above pollution control scheme all cannot effectively control or shorten the time of landfill yard Selfstabilizing, i.e. pollution time of landfill gas and percolate and pollution range.Need the common cooperation of several scheme to implement just can reach the object of regulation comprehensively, cause engineering proposal complicated thus, matching coordinative difficulty, disposes and expends the problems such as high, finally make landfill yard pollution control overlong time, Environmental capacity limited efficiency.Therefore for the difficult point that the renovation of old landfill yard is in environmental protection work always.
Therefore developed inside aeration (In-Situ Belueftung) technology of refuse landfill in recent years, and be exactly the anaerobic state changing landfill yard inside, transferred oxygen condition to.Like this, the inner original anaerobic organism reaction of landfill yard will be stopped, then starts aerobe reaction.The originally poisonous and harmful product that produces of anaerobic reaction, such as, biogas and percolate etc. also by the carbon dioxide that produces by aerobic reaction and water substitute.Air is blasted landfill yard inside by this disposing technique, by blasting the diffusion of gas in landfill yard inside, makes its inside transfer oxygen condition to.Utilize the feature that the biology aerobic reaction time is short simultaneously, reach the debirs stablizing landfill yard in a short time, and then stable landfill yard, control the generation of landfill gas and leachate contamination.Namely disclose a kind of by reaching the effect of rapid degradating solid refuse to solid refuse delivered inside air as Chinese patent 200510011155.6.But these technology all merely provide basic fundamental concept, and do not carry out refinement analysis for soot concrete condition, this situation makes these inner aeration process disclosed at present be difficult to carry out practical application.
Summary of the invention
On the basis of above-mentioned inner aeration process, through the research for many years of applicant, create one more rapidly and efficiently, overall economic efficiency is higher, is more suitable for the inside aeration system of the townm refuse landfill yard of practical application.The concrete steps of this technique are as described below:
(1) in the suitable location of refuse landfill, the air supply pipe of densely covered pore on vertical or horizontally embedded multiple tube wall, this air supply pipe is supplied to the gas of refuse landfill delivered inside by compression pump, gas to air supply pipe conveying is special processed gas, from air feed apart from 15-20cm depths, earth's surface until the bottom of Aerated Landfill Layers, it is 5-10 rice that the density of air supply pipe is set to adjacent air supply pipe spacing distance, and the supply gas pressure of compression pump is determined according to the landfill density in soot;
(2) layout exhaust tube around air supply pipe, exhaust tube is connected with aspiration pump and carries out high pressure and bleed, the speed of exhaust is determined according to the rule being greater than gassing rate 10% ~ 20%, the location arrangements of exhaust tube is for be arranged in around each air supply pipe equably, the gas extracted out enters gas processing device, again drains into air after carrying out harmless treatment to gas;
(3) in air supply pipe and exhaust tube, be provided with gas temperature sensor, gas humidity sensor, the gas temperature of described sensor measurement and humidity data are sent to air feed Gas controller;
(4) multiple monitoring point is set in refuse landfill, the inner detector in soot is set respectively, this detector comprises gas content analyzer, Temperature Humidity Sensor and pH meter, described gas content analyzer can by the gas composition analysis of institute monitoring point out, Temperature Humidity Sensor then can measure temperature and the water content of the rubbish of position, the pH value of rubbish then measured by pH meter, all data are sent to soot controller, above-mentioned monitoring point is all arranged on the mid-point position of certain air supply pipe and adjacent exhaust tube, and the degree of depth of monitoring point is at distance earth's surface below 30cm;
(5) monitoring point regularly arranged in step (4) samples to deep layer rubbish oxygen animalcule Activity determination of acting charitably of going forward side by side, and detection method adopts BacTiter-Glo
tMmicrobial cell activity test method, detects data input central controller;
(6) by central controller, operational analysis is gathered to the detection data from air feed Gas controller, soot controller, compare with the normal operating conditions value of setting, central controller sends signal according to operation result to gas machining control device, gas processing plant is instructed to carry out difference processing to air feed, central controller also sends signal according to operation result to compression pump and aspiration pump in addition, instruct air pump work, aerobic microbiological activity data is for reference as the response parameter of one section of refuse landfill in period ruuning situation.
The wherein said gas to refuse landfill delivered inside is the gas through processing, concrete processing method is as follows: prepare solid APP 50-60 part, talcum powder 5-10 part, above-mentioned raw materials is mixed, select air-flow crushing, pulverize particle mean size and be less than 3 microns, obtained aerosol, this aerocolloidal concentration is 1400-1600mg/L, after this aerosol mixes with pressure-air when needed by compression pump to rubbish inside air feed, the ratio that aerosol mixes with air is 1: 3000-1: 5000.
Preferably, the above-mentioned gas to rubbish delivered inside also adds oxygen, and oxygen content gas is increased to 40%-50%.
Preferably, the above-mentioned gas to rubbish delivered inside also adds water, by the regulation of relative humidity of conveying gas to 70-80.
The supply gas pressure of wherein said compression pump is determined according to the landfill density in soot, concrete defining method is as follows: when the landfill density in soot is less than or equal to 1.40kg/L, the supply gas pressure of compression pump is 5-6 standard atmospheric pressure, when the landfill density in soot is greater than 1.40kg/L and is less than or equal to 1.55kg/L, the supply gas pressure of compression pump is 6-7 standard atmospheric pressure, landfill density when soot is greater than 1.55kg/L, and the supply gas pressure of compression pump is 7-9 standard atmospheric pressure.
