A kind of air mixing micro-electrolysis reactor and reaction method

Abstract

The invention discloses an air mixed micro-electrolysis reactor and a reaction method. The reactor comprises a reaction cylinder, a flow guide cylinder and a flow guide pipe, the flow guide cylinder is arranged in the reaction cylinder, a gap is formed between the lower end of the flow guide cylinder and the bottom of the reaction cylinder, the upper end of the flow guide cylinder is lower than the liquid level of sewage in the reaction cylinder, the flow guide pipe is coaxially arranged in the flow guide cylinder, one end of the flow guide pipe extends downwards and closes to the lower end of the flow guide cylinder, and the other end of the flow guide pipe extends upwards to outside the reaction cylinder and is connected with a first air pump. According to the reaction method, iron powder and carbon powder are thrown into the reaction cylinder, and air floats to drive inner and outer sewage of the reaction cylinder to circularly flow. The iron powder and the carbon powder are mixed to serve as fillers, so that the fillers are avoided from hardening in the reacting process, change of the fillers is avoided, the flow guide cylinder is arranged in the reaction cylinder, the air floats to drive the sewage in the reaction cylinder to move upwards, so that the inner and outer sewage of the reaction cylinder is driven to circularly flow, and the contact rate among the fillers, the air and the sewage is improved, so that micro-electrolysis reaction efficiency and sewage treatment efficiency are improved.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to an air-mixed micro-electrolysis reactor and a reaction method. Background technique [0002] Iron-carbon micro-electrolysis is a good process for treating wastewater by using the principle of metal corrosion to form a primary battery, also known as internal electrolysis, iron filings filtration, etc. The micro-electrolysis technology is to use the micro-electrolysis material filled in the wastewater to generate a 1.2V potential difference to electrolyze the wastewater to achieve the purpose of degrading organic pollutants without electricity. [0003] The existing iron-carbon micro-electrolysis is mainly equipped with an iron-carbon mixed layer as a filler. The particle size of the filler after mixing is generally 1 to 4 cm. , the iron content will decrease, resulting in the need to replace the filler after a certain period of use, but the replacement of the filler is difficult and...
