Problems solved by technology

[0006] At present, the micro-electrolysis equipment at home and abroad are all fixed beds, which are characterized by simple structure and good push-flow performance, but there are still many problems: first, the efficiency is not high and the reaction speed is slow; second, the bed body is easy to harden, resulting in short circuit and death area; the third is that the labor intensity of iron scrap supplementation is high

Abstract

The invention provides a rotary iron-carbon micro-electrolysis reactor and a wastewater treatment method, and relates to the technical field of wastewater treatment. The rotary iron-carbon micro-electrolysis reactor comprises a shell with a cover, a water inlet tube, a water outlet tube, an air vent and a rotary drum, wherein the water inlet tube and the water outlet tube are arranged on two sides of the shell; the air vent is formed in the shell; holes are uniformly formed in the rotary drum; the rotary drum is horizontally arranged in the shell; rotating shafts are arranged at two ends of the rotary drum and extend out of the shell; the rotating shaft at one end of the rotary drum is connected with a motor through a transmission device; the rotary drum is provided with a cover body capable of being opened; a barrel which consists of a sieve is arranged in the rotary drum; and an iron-carbon filler is arranged in the barrel. By the rotary iron-carbon micro-electrolysis reactor, the technical problems that a bed body of the traditional fixed bed type micro-electrolysis reactor is easy to cake, the reaction efficiency is low, and fillers are inconvenient to change are solved. According to the reactor, the filler is in full contact with water by a rotary mode, and the filler is prevented from being caked. In addition, the barrel in the rotary drum can be changed to directly change the filler, the rotary iron-carbon micro-electrolysis reactor is convenient to operate, and the reactor which treats wastewater is high in efficiency and good in effect.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a rotary iron-carbon micro-electrolysis reactor and a wastewater treatment method. Background technique [0002] Iron-carbon micro-electrolysis technology 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. Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater, also known as internal electrolysis. It uses the micro-electrolytic material filled in the wastewater to generate a 1.2V potential difference to electrolyze the wastewater to degrade organic pollutants without electricity. [0003] Since the birth of micro-electrolysis treatment of wastewater, it has attracted the attention of environmental protection researchers at home and abroad, and has carried out a lot of research, and has ...
