Abstract

The invention discloses a reaction device for iron-carbon micro-electrolysis. The device comprises a reaction chamber and an aeration chamber positioned below the reaction chamber, the reaction chamber and the aeration chamber are separated through a screen, the reaction chamber is divided by a plurality of screens with different meshes to form a multistage filler chamber, an iron-carbon filler isarranged in the multistage filler chamber, the bottom of the aeration chamber is provided with a plurality of aeration ports, the sidewall of the multistage filler chamber is provided with a returnedwater inlet, the returned water inlet is connected with the water outlet of a return pump through a return channel, the water inlet of the return pump is connected with a water outlet arranged on a material supplementing tank, and a water outlet arranged at the upper portion of a fourth filler chamber is connected with a water inlet arranged on the material supplementing tank through a pipeline;and the sidewall of the multistage filler chamber is provided with an ultrasonic generator. The device has the advantages of simple structure, easiness in operation, high removal efficiency of COD, ammonia nitrogen and total nitrogen, high utilization rate and difficult loss of the filler, avoiding of filler blockage, hardening, passivation and other problems, low system investment cost, low operation cost and good economic benefit.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a reaction device for iron-carbon micro-electrolysis. 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. It is also called internal electrolysis and iron filings filtration. Sedimentation and redox to remove pollutants in wastewater. As a pretreatment technology before biochemical treatment, iron-carbon micro-electrolysis technology can not only degrade a large amount of organic matter in wastewater, but also reduce its toxicity and improve the biodegradability of wastewater. This method has many advantages such as wide application range, good treatment effect, long service life, low cost and convenient operation and maintenance. As a treatment method using scrap iron scraps as raw materials, it has the meaning of "treating waste with waste"....
