Description

technical field

[0001] The invention relates to a microbial nitrogen and phosphorus recovery battery reactor for water treatment, in particular to a microbial nitrogen and phosphorus recovery battery with three-in-one functions of sewage purification, electricity generation and nitrogen and phosphorus recovery, belonging to the technical field of water treatment. Background technique

[0002] Water resources are an important natural resource for human survival. With the rapid development of industrial society and rapid population growth, the problems of water environmental pollution and water eutrophication are becoming more and more serious. Improving the efficiency of sewage purification and seeking ways to turn sewage into resources have become It is an urgent problem to be solved in the field of sewage treatment. Nitrogen and phosphorus elements are the main pollutants that lead to eutrophication of water bodies, and they are also important resources. Therefore, nitrogen...
