Iron-carbon electrolysis tower for industrial wastewater treatment

Abstract

The invention relates to the technical field of industrial wastewater treatment equipment, and discloses an iron-carbon electrolysis tower for industrial wastewater treatment. The iron-carbon electrolysis tower comprises a tower body. According to the iron-carbon electrolysis tower for industrial wastewater treatment, the interior of an iron-carbon filler is columnar, the outer ring is conical, the height of the outer ring is larger than that of the inner ring, the iron-carbon filler is matched with the other four iron-carbon fillers on the peripheral conical surface of the iron-carbon filler in the vertical direction, and a new iron-carbon filler is in contact above the four iron-carbon fillers, namely right above the iron-carbon filler supporting the four iron-carbon fillers, such that the diffusion outward and accumulation upward enable the iron-carbon fillers to be driven by the rotating shaft to rotate, the contact surfaces of the iron-carbon fillers are rubbed, the outer surface is prevented from being passivated, and sewage and iron ions are isolated; and in the rotating process of the iron-carbon filler arranged in a stepped mode, sewage can flow upwards through the electrolysis holes, so that iron ions separated out of the inner surfaces of the electrolysis holes can be impacted upwards, the electrolysis holes are prevented from being blocked, and the purification effect is prevented from being weakened.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment equipment, in particular to an iron-carbon electrolysis tower for industrial wastewater treatment. 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. Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater. It uses the potential difference generated by the micro-electrolytic material filled in the waste water to electrolyze the waste water without electricity, so as to achieve the purpose of explaining organic pollutants. [0003] Iron-carbon micro-electrolysis is based on the primary battery reaction in electrochemistry. When iron and carbon are immersed in sewage, sewage is used as an electrolyte. Since there is a 1.2V electrode pote...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an iron-carbon electrolysis tower for industrial waste water treatment. The outer surface of the iron-carbon filler will not be passivated, the flocs will not be deposited in the electrolysis chamber, and the iron-carbon filler will not be cracked quickly. The advantage of agglomeration and blockage solves the problem of iron-carbon filler passivation and isolation of sewage, flocs deposited in the electrolysis chamber, iron-carbon filler cracking rapidly, resulting in no iron-carbon filler in the upper part of the electrolysis chamber, and incomplete purification of discharged sewage
