Efficient treatment and resource utilization method and system for leachate of garbage transfer station

Abstract

The invention discloses an efficient treatment and resource utilization method and system for leachate of a waste transfer station. The characteristics of the garbage transfer station leachate and the EGSB system are combined, waste is treated, biogas is generated, the garbage transfer station leachate treated by the EGSB is reused, clean energy-electric energy is generated, the energy utilization rate is increased, meanwhile, the environment is protected, and good economic and environmental benefits are achieved. The process flow is simple and convenient, and various tedious sewage treatment units, such as membrane treatment, of other treatment methods are omitted.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and resource utilization, and relates to a method and system for efficient treatment and resource utilization of leachate in a garbage transfer station, especially a method and system for synchronously producing biogas from leachate in a garbage transfer station using EGSB and MFC coupling technology. way of electricity. Background technique [0002] With the continuous improvement of people's living standards, the amount of garbage produced is also increasing. High demands are also placed on the disposal and transport of waste. The promotion and application of garbage transfer stations have beautified the environment, reduced the breeding of mosquitoes and flies, improved vehicle efficiency, reduced labor intensity of workers, and greatly reduced operating costs. However, the treatment of leachate in garbage transfer stations is a difficult problem. The traditional leachate treatment p...

Problems solved by technology

However, there are few reports on the comprehensive treatment technology for the efficient treatment and resource utilization of the leachate water quality characteristics of the garbage transfer station.

Although there have been reports on the treatment effect and operating characteristics of the UASB-MFC coupling system for high-ammonia nitrogen wastewater, this study only investigated the operating characteristics of the nitrogen pair coupling system under different C / N ratios and revealed that N plays an important role in the anaerobic digestion process. mechanism of action; moreover, the institute uses glucose as the carbon source and ammonium chloride as the simulated wastewater composed of ammonia nitrogen, the water quality components are simple
