Problems solved by technology

Although the overall load rate of the reactor is higher compared to the UASB reactor conditions, because the internal circulation body does not pass through the finishing zone, the rising flow rate in the finishing zone is also low, which can maintain the best solids retention

Description

technical field [0001] The invention relates to the field of electrolysis technology, in particular to a wastewater treatment technology. Background technique [0002] The principle of wastewater treatment process: micro-electrolysis is based on the galvanic reaction in electrochemistry. When iron and carbon are immersed in the electrolyte solution, since there is an electrode potential difference of 1.2V between Fe and C, countless micro-battery systems will be formed, forming an electric field in their action space. The new ecological ferrous ions produced by the anode reaction have a strong reducing ability, which can reduce some organic substances, and can also make the bis The bond is opened to decompose some refractory cyclic and long-chain organic compounds into easily biodegradable small molecule organic compounds to improve biodegradability. In addition, divalent and ferric ions are good flocculants, especially nascent ferrous ions have higher adsorption-flocculat...
