Benefits of technology

This patented technology uses tiny particles called microspheres made from materials like metal or silicon carbons (SiC) suspended inside an aqueous solution containing hydrogen peroxide dissolved therein. These small spherules can be easily mixed into larger ones without losing their original shape when they come off during manufacturing processes. They have low surface energy causing them to stick together tightly even if it gets wet due to rain. Microbubbles produced through this technique help break up any excess liquid before reaching the end user's equipment. It achieves these benefits while reducing environmental pollution caused by chemical reactions involved.

Problems solved by technology

Technics described in the technical problem addressed in this patents involve improving the efficient removal of highly concentrated organic wastes from various sources like industry or environmental concerns through advanced oxydative techniques involving enzymes with strong oxidization capabilities and selective properties.

Abstract

The invention discloses a method for degrading industrial organic wastewater by ultrasonic wave ozone-microelectrolysis coupling. According to the method, industrial organic wastewater is subjected tofront-end treatment by using micro gas bubbles generated by ultrasonic oscillation and plasma ozone output by a gas distribution plate, so that the escape of ozone is avoided, and the utilization rate of ozone is increased; and sponge iron, a carbon molecular sieve, a small amount of a catalyst and a binder are used as a reinforced iron-carbon microelectrolysis filler, wherein sodium chloride isadded into the catalyst as a reaction electrolyte so as to improve the reaction efficiency, and the binder with a certain conductivity promotes the stable performing of a microelectrolysis reaction. According to the invention, by additionally arranging a movable turbine turnover stirrer during the use, the complete reaction time of an iron-carbon micro-battery and wastewater is guaranteed, and theproblem of hardening of the microelectrolysis filler is solved; and the method is high in treatment efficiency, high in raw material utilization rate, safe and reliable.
