A microbial nitrogen and phosphorus recovery battery reactor for water treatment

Abstract

The invention relates to a reactor of a microbial nitrogen and phosphorus recovery battery for water treatment and belongs to the technical field of water treatment. The reactor comprises a shell, an anode, a cation exchange membrane, a cathode, an anion exchange membrane and the like, wherein the cation exchange membrane and the anion exchange membrane sequentially divide the inner cavity of the reactor into an anode chamber, a nitrogen and phosphorus extraction chamber and a cathode chamber; an anode is suspended in the anode chamber, a cathode is fixedly arranged on the side wall of the cathode chamber, and the bottom of the anode chamber is communicated with the bottom of the cathode chamber through a pipeline; and the anode is connected with the cathode through a wire. The reactor provided by the invention can be simultaneously used for realizing purification of domestic wastewater, electricity production, nitrogen and phosphorus removal and struvite generation and is simple in structure, easy to operate and maintain, low in energy consumption, high in efficiency and convenient for industrialized production and practicality.

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...

Problems solved by technology

First of all, hydrogen ions are produced during the catalytic oxidation of organic matter in sewage by electrogenic microorganisms. Excessive accumulation of hydrogen ions will lead to a decrease in the power generation performance of the device and a reduction in the treatment rate; in addition, this process can only degrade organic matter, but cannot remove nitrogen and phosphorus Elements, the subsequent special nitrogen and phosphorus treatment process is still required to achieve the complete purification of sewage
