Abstract

The present invention proposes "A Method for Efficient Anaerobic Degradation of Fulvic Acid in Waste Incineration Leachate", which promotes the degradation of fulvic acid by strengthening the bioelectrochemical reaction in the reactor, and belongs to the field of anaerobic biological treatment of high-concentration refractory organic wastewater . The method relates to a complete set of devices for efficiently degrading fulvic acid. The method comprises the following steps: firstly inoculating anaerobic sludge according to the volume ratio of sludge and leachate of 30%-40%; then placing electrodes inside the anaerobic reactor and applying DC voltage for treatment. Compared with the existing technology, this method not only realizes the effective removal of COD in the leachate, but also promotes the efficient degradation of fulvic acid substances in the leachate, which is beneficial to the subsequent treatment of the effluent. At the same time, the system increases methane production, which can completely offset the power loss during the treatment process and realize energy-saving treatment.

Description

technical field

[0001] The invention relates to a technology for degrading fulvic acid in waste incineration leachate. Mainly through the anaerobic methanogenesis bioreactor coupling microbial electrolytic cell, strengthen the microbial electrochemical reaction, achieve the purpose of efficient degradation of fulvic acid, this method belongs to the field of biological treatment of high-concentration refractory organic wastewater. Background technique

[0002] With the progress of society and the improvement of human living standards, the output of municipal solid waste is also increasing year by year. In 2015, the total amount of municipal solid waste generated in large and medium-sized cities in my country has exceeded 180 million tons. With the limitation of land resources and the vigorous development of waste incineration, the proportion of traditional waste landfills to treat municipal solid waste has decreased year by year. Incineration has gradually become another majo...
