Sectional type consumer waste ecological burying simulating device

Abstract

The invention discloses an ecological landfill simulation device for sectional type household garbage, comprising an upper end reactor, a hollow post and a lower end reactor which are connected with each other in the same axis line from top to bottom. The hollow post is in favor of the establishment of the environment of 'from aerobiosis to oxygen poor to anaerobic process' under the whole simulation environment, facilitates percolation liquid to have natural re-oxygenation when the percolation liquid drips in the hollow post, strengthens the nitrification and promotes the elimination of nitrogen in garbage dump bodies while methanogenesis is not interfered. With the operation of the simulation device, the nitrogen migration and transformation and the variation rule of nitrogen circulation function microbial community structure of the percolation liquid in artificial recharge process are identified and provide theoretical base for actual construction application. Meanwhile, after the disassembly of the hollow post in the invention, the upper end reactor and lower end reactor can be respectively assembled into general integral type garbage ecological landfill simulation devices, which are used for implementing garbage degradation research experiment in the artificial recharge process of the percolation liquid under general condition and greatly widens the application scope of the invention.

Description

technical field [0001] The invention relates to a segmented living garbage ecological landfill simulation device, which belongs to the technical field of environmental protection. Background technique [0002] With the improvement of urbanization and residents' living consumption level, the generation of municipal solid waste is increasing day by day. As a final treatment and disposal method, sanitary landfill has been widely used due to its simple process, low investment, large processing capacity and low operating cost. It is currently one of the most commonly used methods for the harmless treatment and disposal of municipal solid waste at home and abroad one. However, this technology has also increasingly exposed its limitations, such as large land occupation, difficult site selection, serious damage to the surrounding ecological landscape, stench and breeding of mosquitoes and flies. The leachate with high concentration is difficult to degrade, and the high concentrati...
