Description
Technical field
The utility model relates to a kind of monitoring test device, more specifically relate to a kind of rainfall earth pillar monitoring test device, be mainly used in the rule and the behavior of the transmission under Duo Chang (temperature-moisture-pressure) coupling of quantification dynamic monitoring garbage loading embeading gas and percolate, be used for the study on monitoring of city refuse landfill pollutant.
Background technology
The environmental pollution that the refuse landfill pollutant causes has become one of the most outstanding at present and in the future environmental problem, and pollutant is many with its amount, pollution range is wide, pollution level heavily waits characteristics to become focus and focal issue in the current ecologic environment.International statistics show that seepage generally takes place in early stage refuse landfill, and they ceaselessly are being seeped in the water environment down.Monitoring shows that seepage generally takes place in the refuse landfill of China, and in each big city refuse landfill field monitoring was estimated, refuse landfill seepage in Pekinese's was more obviously with outstanding.Several toxic pollutantss that are detected mostly belong to the hardly degraded organic substance (POPs) of the preferential control of United Nations Environment Programme (UNEP) and China toxic chemical Register (NRPTC) delimitation.These pollutants are its environmental capacity head and shoulders above, forms the fragile link of ecologic environment.Groundwater contamination is unprecedentedly serious at present, is the hotbed of having completed of all kinds of disastrous pathologies, and situation is very severe.Current, China's garbage loading embeading has entered the peak period, and the phreatic phenomenon of city refuse landfill leakage pollution takes place repeatedly, has become the difficult problem that all circles pay close attention to and feel to feel simply helpless.Especially the seepage that is located in the landfill yard of urban groundwater updrift side, it directly has influence on the city common people's drinking water source.Simultaneously, soil or sand soil that landfill gas can see through the landfill yard periphery flow, and can record 5% landfill gas CH in the buildings beyond the 100-200m
4The leakage of landfill gas and distribute the environment of serious threat around, near landfill yard, it can become fatal material, when the concentration of methane reaches 5-15% in air, will blast and burn, all must estimate during as near exploitation refuse landfill its potential danger.In recent years, external Ankara Istanbul, Manila, Philippine capital, ground such as domestic Shanghai, Yueyang, Chengdu, Beijing all have because the disguised outside the venue accident that landfill gas causes in the landfill yard takes place.Cause basic reason that these accidents take place to be the research work of the rule aspect of garbage loading embeading gas and the transmission of percolate potentiality is not caused enough attention, do not carry out relevant basic research.
Rubbish is once landfill, consume inner oxygen with regard to the microbial degradation that is accompanied by rubbish and produce a large amount of heats, the landfill yard internal temperature raises, and not only influences the physical property of rock soil mass, and the stress field of ground and the seepage field of fluid (landfill gas and percolate) are also had important effect.Simultaneously fluid has significant effects as a kind of environmental factor to the physico-mechanical properties and the thermal convection transmission of ground; On the other hand, the seepage flow of the thermophysical property convection cell of ground and heat conduction play important control action.The character of connecting each other between this three, mutual restriction is caused by deformation field, seepage field and temperature field coupling effect.The migration of landfill pollutant (landfill gas and percolate) in landfill yard is a very complicated process, wherein relate to many definite or uncertain factors, in order to control and to reduce landfill gas and the amorphous release of percolate, alleviate its pollution to ecologic environment, the concentration of emission that reclaims the energy gas in the landfill gas to greatest extent and reduce percolate, just must carry out the quantification test, must carry out study on monitoring to the transmission course of landfill pollutant with the means of test to the dynamic perfromance of the transmission of landfill gas and percolate.
Yet mainly there is the problem of the following aspects in the correlation test equipment of having researched and developed at present both at home and abroad:
(1) equipment all can't be realized the test simulation of temperature-moisture-three couplings of pressure, and can only carry out test simulation at single game (only considering pressure, moisture or temperature action).
(2) in process of the test control and data acquisition, mostly equipment in the past is to utilize manual operations and record, some equipment has used the area of computer aided record data, but can't carry out real-time follow-up, control and monitor the test process, easily cause the too discrete of waste of manpower resource and test figure, test accuracy is brought adverse effect.
(3) most equipment have only single and fixing interface, and then equipment can't be expanded to satisfy the further needs of research.And can't carry out reasonable replacement to instrument, caused the expansibility of equipment and dirigibility not high, function singleness.
(4) existing equipment is long at its cycle of the experimental study of carrying out under the varying environment condition, can't solve many complete equipments and carry out orthogonal test research simultaneously.
For this reason, when measuring the correlation parameters such as Penetration Signature, transfer rate and hydrodynamics of landfill gas and percolate, just can not simply consider the influence of certain single factors, temperature-moisture-stress must be coupled together and carry out system simulation research, the test figure that records like this reflects the actual operation situation of landfill yard more.The monitoring test system of landfill gas and percolate transmission course is resolution system coupling analysis difficulty just, and the inaccurate and test condition of data monitoring is difficult to control this problem and develops.This pilot system not only can quantitatively be analyzed percolate and landfill gas dynamic perfromance, and the control and the exploitation of landfill gas resource that can be the pollution of percolate simultaneously provide basic test figure.
