A simple landfill aerobic bioreactor treatment system and method

Abstract

An aerobic bioreactor processing system for a simple landfill is composed of an aerobic bioreactor, a circulating fan, a deduster, an exhaust fan, a deodorizing device, an exhaust barrel, a torch and a heater. The aerobic bioreactor is composed of anchoring ditches, a cover film, gas injection wells, gas extraction wells, rainfall water collecting wells, a recharge device, a simple landfill engineering boundary, a simple landfill flat surface and an online detector 17. After flattening and slope finishing of the simple landfill, the wells are dug in the simple landfill flat surface, the film covers the simple landfill flat surface, and the rainfall water collecting wells are dug around the landfill boundary; and after landfill gas in the landfill is extracted, forced circulating ventilation is conducted on refuse dump bodies, and the stability of the landfill is improved. Through optimization of system configuration, the unit structure and an operation method, the aerobic bioreactor processing system is suitable for treating and repairing the simple landfill, and the operation cost is lowered.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection domestic waste treatment, and is a simple landfill aerobic bioreactor treatment system and method. Background technique [0002] For the resource utilization of simple storage yards, most foreign countries use old garbage directly or after screening. The main ways of utilization are: as a supplement to planting soil, as a covering material, as a building material, and as a filter material for deodorization. Foreign literature records that the earliest landfill mining project was the Tel Aviv landfill mining project in Israel in 1953. The main purpose of mining was to take soil from the landfill as a supplement to the soil for citrus planting. [0003] There are a large number of centralized garbage dumps or simple landfills in major cities in my country (almost all cities above the county level) or around the cities, which do not meet the sanitary landfill standards, and even do not have...
