Method for strengthening purification of bottom mud through iron-carbon positive electrode microbial fuel cell

Abstract

The invention relates to a method for strengthening purification of bottom mud through an iron-carbon positive electrode microbial fuel cell. Pollutants in the bottom mud can be effectively removed, through the further utilization of an online monitoring technology, the microbial fuel cell generates electricity to monitor the condition of water quality, and subsequent monitoring and treatment of the water quality are facilitated. According to the technical scheme, a microbial fuel cell system is utilized, iron-carbon micro-electrolysis filler and a biological negative electrode ribbon are coupled, desilting for a river channel is not needed, the microbial fuel cell is suitable for various water quality conditions, simple in structure and easy to construct, has good effects of removing organic matter in water, removing nitrogen and the like, and is suitable for river channel regulation, secondary pollution caused by the bottom mud is reduced, and the method is an innovation in bottom mud pollution regulation methods.

Description

technical field [0001] The invention relates to the field of ecology and environmental protection, in particular to a method for strengthening and purifying sediment by an iron-carbon anode microbial fuel cell. Background technique [0002] my country is facing serious water pollution and shortage of water resources. Pollutants such as organic matter and ammonia nitrogen in water, especially some persistent pollutants that are difficult to degrade, have poor biodegradability in the environment and exist for a long time. They can be absorbed by precipitation or particulate matter. It is stored in the sediment and released again under appropriate conditions, becoming a secondary pollution source, causing the water body to be "permanently cured". At present, there are many problems in our country such as persistent pollution of a large number of rivers and lakes, difficult treatment of bottom mud, and secondary pollution of water bodies by bottom mud. [0003] In the process of...
