Air pressure temperature control type landfill pollutant transfer characteristic test system

Abstract

The invention discloses a pressure temperature-controlling type transmission characteristics test experimental system of landfill contaminants, which comprises a water bath temperature control system, a waste landfill body circulating water bath heating system, an automatic percolate returning system, a landfill gas permeability coefficient determination system and a percolate permeability coefficient determination system. The experimental system can achieve such tests as the automatic temperature control of water bath, circulating heating of waste landfill body, automatic returning of percolating water, landfill gas and percolating water in the water landfill body. The experimental system has the advantages of simple structure, compact assembly, strong operability, short experiment period and wide application, and has important application value in developing the study of transmission rule of landfill gas and percolate in the landfill body, resource exploitation of landfill gas, contaminant control, sedimentation of waste landfill body, etc.

Description

technical field [0001] The invention relates to an air pressure temperature-controlled landfill pollutant transmission characteristic test system, which is mainly used for the dynamic change law of the landfill pollutant transmission under different temperatures and different leachate recharge loads. The test belongs to the field of resources and environment technology. Background technique [0002] Environmental pollution caused by garbage pollutants has become one of the most prominent environmental problems today. Pollutants have become a hot and focused issue in today's ecological environment due to their large amount, wide distribution, long degradation time, and heavy pollution. . The monitoring shows that leakage is common in landfills in my country. In the on-site monitoring and evaluation of landfills in major cities, the leakage of landfills in Beijing is more obvious and prominent. Most of the detected toxic pollutants belong to the priority controlled refractor...

AI Technical Summary

Problems solved by technology

On-site monitoring experiments can only reflect the recent landfill gas production and leachate seepage, but cannot reflect the entire gas production and seepage process of the landfill, and engineering applications must have the data of the entire process

The lack of current test data (especially comprehensive and comprehensive test data) seriously restricts the development of solid-liquid-gas interaction and multi-field coupling models in landfills and the accuracy of prediction results.
