Malodorous gas processing system for sanitary landfill yard

Abstract

The invention relates to a foul gas processing system in a waste sanitary landfill site. The system comprises an air supporting membrane structure, a blast fan, pressure control equipment, a pressure sensor, a computer terminal system, a monitoring system, an automatic exhaust valve, gas processing equipment, an exhaust fan, and a chimney; the edge of an air brace type membrane structure is connected with a rigid supporting structure or foundation pre-embedded in a waste landfill operation region; a sensor of the monitoring system is arranged inside the air brace type membrane structure; the monitoring system, the blast fan and the exhaust fan are connected with the computer terminal system; the pressure sensor is connected with the pressure control equipment; the pressure control equipment is connected with the computer terminal system; the automatic exhaust valve is arranged on the air supporting membrane structure and is connected with the gas processing equipment and the exhaust fan; and the exhaust fan is connected with the chimney. The foul gas processing system has the advantages that the system carries out good airflow organization on foul gas produced in the waste landfill operation region, carries out effective control and processing on the organized airflow so that the foul gas is not diffused towards the periphery of the landfill site, and can greatly reduce the amount of leachate brought by precipitation.

Description

technical field [0001] The invention relates to a system for treating malodorous gas in sanitary landfills of garbage. Background technique [0002] At present, in order to control the malodorous gas produced by large-area, open sanitary landfills, the landfill solid waste is covered in time with sand and covered with a covering film to reduce the exposed area of ​​the piled waste, thereby reducing the odor diffusion area. Control it; on this basis, some landfills spray deodorizing agents on the garbage dumps from time to time, and reduce the concentration of garbage odor through the action of deodorizing agents and the components in the odor. Due to the special environment of the landfill site, the area of ​​the landfill is large, the source of the odor is wide, and all of them are in the open air. In the process of spraying deodorant agents, the spraying amount of the agents is large, the cost is high, and the duration is short. It may also inhibit the production of metha...

Problems solved by technology

[0004] The purpose of the present invention is to provide a system for treating malodorous gas in garbage sanitary landfills, to solve the above-mentioned existing problems in the operation area of ​​existing garbage landfills, and to organize the airflow of unorganized malodorous gases in a closed enclosed space , reduce the amount of leachate produced by blocking the direct contact between precipitation and landfill waste, and then block the diffusion of bacteria, mosquitoes, dust and waste plastics to the external environment
