Electrically induced condensation ozone flotation-catalytic oxidation multiple coupling water treatment system and method

Abstract

The invention relates to an electric induction condensation ozone flotation-catalytic oxidation multi-factor coupling water treatment system and method; a copolymer of an amorphous hydroxide-metal ion system with polar macromolecules, colloids, emulsified oil and other pollutants is formed in water through an electric induction effect; a nascent state [H] and hydroxyl free radicals formed along with the electric induction condensation process can perform oxygenolysis on organic matters in treated water; then an O3 / Me system is formed by ozone in dissolved gas water and metal ions in the treated water, difficult-to-degrade organic matter structures are promoted to be destroyed, tail end inert groups are converted into functional groups having adsorption activity, and the copolymerization complexing ability of the organic matters with electric induction condensates is enhanced; homogenized micro-bubbles formed by a dissolved gas backflow water system are strongly attached onto the surface of the copolymerization complexing system formed in the water, and the copolymerization complexing system is taken away from the treated water system by floating-upward effect of the micro-bubbles, and thus the efficient solid-liquid separation is completed. The system and the method have strong adaptability, the water quality of the treated water is good, the labor intensity of an operator is low, and main points of the operation are easy to master.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment, and in particular relates to an electric induced condensation ozone flotation-catalytic oxidation multi-coupling water treatment system and method. Background technique [0002] Generally speaking, pollutants in water can be divided into suspended solids, dissolved pollutants, chromaticity, and microorganisms such as bacteria and viruses. For suspended solids and pollutants that exist in water in stable dispersion systems such as colloids and emulsified oils, the most mature, easy-to-operate and low-cost technical means is to use coagulation; when there is chromaticity in water, oxidation is generally used. Removal of chromaticity in water by the method; natural / synthetic soluble and refractory organic substances will be continuously enriched in water through the food chain, and finally passed to humans at the top of the food chain. The most commonly used treatmen...

Problems solved by technology

For decentralized wastewater generation points, building complex water treatment facilities at a single site with a small amount of water to be treated requires large project investment and high operation and maintenance costs; on the other hand, it requires strict quality requirements for operators at a single site
