Iron-carbon micro-electrolysis reactor for removing phosphorus from sewage

Abstract

The invention discloses an iron-carbon micro-electrolysis reactor for removing phosphorus from sewage. The iron-carbon micro-electrolysis reactor comprises a sewage treatment box, a rotating structure, a roller and an aeration assembly, wherein the rotating structure comprises a driving piece and a rotating shaft connected with the driving piece, the roller is located in the sewage treatment box,is fixedly installed on the rotating shaft, rotates along with the rotating shaft, and is filled with a micro-electrolysis filler, the roller rotates to drive the micro-electrolysis fillers to collideand rub each other, the aeration assembly comprises an air blower, an air inlet pipe and an aeration film pipe, the air blower communicates with the aeration film pipe through the air inlet pipe, theaeration film pipe is located at the bottom of the sewage treatment box, and the roller rotates to drive the micro-electrolysis filler to collide and rub with each other to remove an oxide film on the surface of the micro-electrolysis filler so as to continuously electrolyze the micro-electrolysis filler, and the aeration assembly increases the content of oxygen in sewage and accelerates flocculation generation, so that phosphorus in the sewage is removed.

Description

technical field [0001] The invention relates to sewage treatment, in particular to an iron-carbon micro-electrolysis reactor for phosphorus removal from sewage. Background technique [0002] Iron-carbon micro-electrolysis technology uses wastewater as electrolyte, iron filings in the micro-electrolysis filler as anode and activated carbon as cathode to form a "primary battery". The electrolytic oxidation and reduction treatment of wastewater is carried out through the formation of electric current through discharge. The principle is based on electrochemistry, oxidation- The joint action of reduction and flocculation to achieve the purpose of removing organic pollutants. It has the advantages of wide application range, good treatment effect, low cost, short treatment time, convenient operation and maintenance, and low power consumption. It is widely used in pretreatment and advanced treatment of industrial wastewater. [0003] When the existing micro-electrolysis system is a...

Problems solved by technology

Under the action of external current, dense and non-conductive oxides will be produced during the reaction process to cover the anode, thus hindering the release of metal ions. The passing current of the system continues to decrease, and the electrode reaction rate decreases, which ultimately affects the phosphorus removal efficiency of the electrolytic method, resulting in an increase in cost
