Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a vertical flow micro-electrolysis reaction device. Background Art

[0002] As a conventional sewage treatment process, the iron-carbon micro-electrolysis process shows good potential in removing organic matter, heavy metals, nitrogen, phosphorus and other pollutants from sewage. The micro-electrolysis process is based on the primary cell reaction in electrochemistry. When the pH value of the wastewater is 3-4, when iron and carbon are immersed in the electrolyte solution, due to the electrode potential difference of 1.2V between iron and carbon, countless micro-battery systems will be formed, and an electric field will be formed in its action space; at this time, the new ecological divalent iron ions produced by the anode reaction have strong reducing ability, which can reduce some organic matter, and can also open the double bonds of some unsaturated groups (such as carboxyl-COOH, azo-N=N-), so that some difficult-to-degrade cyclic and long-chain organic matter can be decomposed into small molecular organic matter that is easily biodegradable, thereby improving biodegradability. In addition, divalent and trivalent iron ions are good flocculants, especially newly generated divalent iron ions, which have higher adsorption-flocculation activity. Adjusting the pH value of wastewater can convert iron ions into flocculent precipitates of hydroxides, which in turn adsorb suspended or colloidal tiny particles and organic polymers in the sewage, further reducing the chromaticity of the wastewater; at the same time, some organic pollutants are removed to purify the wastewater, and the cathode reaction produces a large amount of new ecological [H] and [O]. Under slightly acidic conditions, these active ingredients can undergo redox reactions with pollutants in the wastewater, causing chemical reactions such as ring opening and chain breaking in cyclic and long-chain organic matter, thereby improving the biodegradability of the wastewater.

[0003] Micro-electrolysis technology is currently an ideal process for treating high-concentration, difficult-to-degrade, and difficult-to-biodegrade organic wastewater. Its working principle is based on the combined effects of electrochemical oxidation-reduction reactions and flocculation and sedimentation. It has the advantages of wide application range, good treatment effect, low cost, convenient operation and maintenance, and no need for additional power consumption. However, most of the micro-electrolysis reaction equipment currently used is a reaction device with a fixed filler chamber. During use, the micro-electrolysis filler will gradually become hardened and channeled. At the same time, some oil and organic matter are easy to adhere to the surface of the filler, affecting the operation effect of the equipment. Summary of the invention
