Mode of operation and principle:
Alkaline sewage is discharged by alkali cleaning device, through regulating surge tank water inlet pipe to enter adjustment surge tank, regulates surge tank to play adjustment flow, the effect of water quality. Surge tank rising pipe enters alkaline residue lift pump through regulating to regulate the alkaline residue solution in surge tank, filler air-floating apparatus is entered through filler air-floating apparatus water inlet pipe after pressurization, alkaline residue flow of solution is through filler air supporting filler, under the effect of filler air supporting filler, in water, suspended substance, oil grain, colloid electrostatic double layer are destroyed, there is unstability, suspended substance, colloid is condensed into larger particles wadding body; Simultaneously oxygen in water hydration oxygen molecule is rolled into a ball under the effect of filler, forms hydroxyl radical free radical, impels in water the material generation free radical reactions such as solvability grease, organic solvent, tensio-active agent, thus changes its character so that it is is insoluble to water, forms wadding body. Wadding body is floated up to the water surface under the rolling action of rising bubble, is discharged by scum silica frost delivery pipe. Filler air-floating apparatus blast main is responsible in system to blast air, forms bubble and carries wadding body to the water surface. Waste water after processed discharges system by filler air-floating apparatus rising pipe. Through the alkaline residue solution of filler air-floating apparatus process, oily substance is removed. Enter the alkali collection room of band ion-exchange membrane measurements of the chest, waist and hips electrode soda recovery unit through filler air-floating apparatus rising pipe, another acid recovery room, side connects clear water water inlet pipe, is responsible for supplementing clear water to acid recovery room. The alkali collection room back of the body arranges graphite electrode plate to anionic ion exchange membrane side, connects DC power cathode, and the acid recovery room back of the body arranges graphite electrode plate to anionic ion exchange membrane side, connects DC power anode. Outside under alive effect, electric field can be formed between two pieces of graphite electrode plates, the three-diemsnional electrode particle of filling is impelled to polarize, when alkaline residue flows through alkali collection room, under the effect of electric field, negatively charged ion, through anion-exchange membrane, enters acid recovery room, is adsorbed in the electrostatic double layer of three-diemsnional electrode particle surface. Thus complete the separation of zwitterion. The negatively charged ion of alkali collection indoor constantly reduces, and causes sodium cation at the indoor formation sodium hydroxide of alkali collection. Acid recovery room constantly receives the negatively charged ion through anionic ion exchange membrane, forms acid, and its negatively charged ion mostly is the sulfate radical of the oxygenizement oxidation formation that catalyzed dose of sulfide produces, therefore the acid formed is based on sulfuric acid. When alkaline residue solution three-diemsnional electrode particle indoor by alkali collection, under the effect of aeration supplemental oxygen and extra electric field, three-diemsnional electrode particulate catalytic dissolved oxygen, namely there is covalent linkage fracture in hydration oxygen molecule group, forms hydroxyl radical free radical, the organism in oxidized waste water. Alkaline residue solution band ion-exchange membrane three confining electrode soda recovery unit, removes negatively charged ion, organism in water, again forms alkali lye, discharges through alkali collection pipe, again returns to production technique and uses. Clear water control flow enters acid recovery room, receives sulfate radical, forms the sulfuric acid of concentration about about 15%, can for plant area.
Mode of more than implementing is only for illustration of the present invention; and it is not limitation of the present invention; about the those of ordinary skill of technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to the category of the present invention, and the scope of patent protection of the present invention should be defined by the claims.
