Multifunctional garbage soil degradation compression apparatus

Abstract

The invention discloses a multifunctional garbage soil degradation compression apparatus. The apparatus includes an axial compression system, a confining pressure simulation system, a penetrating fluid circulation system, a gas analysis system, an automatic data acquisition system and other auxiliary fitting systems. The apparatus provided pressurizes the test by means of an axial compression device, provides the confining pressure and constant temperature conditions through the gas by means of a temperature controlled pressure confining device, and performs the penetrating fluid uniformly distributed recirculation and degraded gas recovery to test the resistivity of the soil sample. The compressor has the following advantages of 1) solving the limitation that a degrading instrument cannot provide the confining pressure; 2) providing the controllable vertical pressurization setting; 3) performing the dynamic monitoring of penetrating fluid flow velocity, flow and compositions; 4) providing a resistivity testing module and testing the garbage soil resistivity changes in different degrading and deposition stages; and 5) monitoring the degraded gas compositions and flow, and achieving the novel and multifunctional aims.

Description

technical field [0001] The invention relates to the technical field of urban solid waste test equipment, and more specifically, relates to a multifunctional garbage soil degradation compression equipment. Background technique [0002] With the rapid development of my country's urbanization and the rapid increase of urban population, the phenomenon of "garbage siege" is common. Considering that the existing waste disposal method in my country is mainly sanitary landfill, the research on the existing scheme shows that the solid waste after the closure is unevenly settled due to internal degradation, and the internal gas and liquid collection system is broken, especially However, with the continuous increase of landfill volume, it is possible to induce serious environmental geological disasters and pose a direct threat to the safety of human settlements. [0003] With the increase of the proportion of kitchen waste in solid waste, the leachate and landfill gas generated by degr...

Problems solved by technology

[0007] To sum up, in order to solve the problem that the test conditions of the compression instrument in the prior art do not match the force of the actual garbage soil, resulting in a large gap between the test results and the actual situation, it has become an urgent problem to be solved by those skilled in the art.
