The electrochemical ozone generators or systems of the present invention may be used to provide disinfected water, ozone-containing water, and/or ozone gas. Disinfected water may be produced by introducing ozone gas into a potable or purified water source for the purpose of disinfecting or controlling the microorganisms in the water source. Ozonated water or ozone gas may be produced and provided for various anti-microbial and cleansing applications of the consumer, such as washing food, clothing, dishes, countertops, toys, sinks, bathroom surfaces, and the like. Furthermore, the ozone generator may be used to deliver a stream of ozone-containing water for the purpose of commercial or residential point-of-use washing, disinfecting, and sterilizing medical instruments and medical equipment.

Recycled flue gas desulfurization and denitration method

The invention relates to a recycled flue gas desulfurization and denitration method, which sequentially comprises the following steps of: introducing flue gas of SO2 and NOx into a desulfurizing tower, and absorbing the SO2 with a desulfurizing agent (barren liquor) in the desulfurizing tower; desorbing the desulfurizing agent (rich liquor) which absorbs the SO2 through a multi-effect evaporator,releasing the SO2 gas, and concentrating the SO2 gas into liquid SO2 through condensation drying; making the desulfurized flue gas enter a denitration tower, injecting gaseous ozone from an ozone generator, oxidizing the NO in the flue gas, absorbing the oxidized NO by using a denitrifier to form nitrate; crystallizing and separating out the nitrate in the solution after the nitrate reaches certain concentration, and filtering and drying to obtain the nitrate product. The method turns the wastes into wealth, and the SO2 and NOx in the flue gas are recycled by higher-additional value liquid SO2 and nitrate products, so that the recycling and value maximization in the desulfurization and denitration process is realized.

Dyeing and printing waste clearing, synthetic wastewater advanced treatment circulation production and recycle technique

The invention discloses a deep treatment technique used for the printing and dyeing sewage recovery. The technique consists of a BAF pond, an air-bearing system, an ozone contact oxidation tower, a filter, an active carbon filter, an ozone generator and a medicine adding system. The technique is the improvement of the traditional BAF technique, removes the resolvable organism in the sewage through the biological degradation, outtakes the water into the air-bearing system and combines the flocculation medicine adding technique, so as to eliminate the non-solvent organism and colloidal substance in the sewage. The outtaken water enters into the ozone contact oxidation tower and gets mixed with ozone, so that the organism which is difficult to undergo the biological degradation in the printing and dyeing sewage is removed with the help of the strong oxidizing property of the ozone. The water flowing out of the ozone contact oxidation tower enters into the pond at the middle, and 30 percent of the water returns to a gas dissolving can under the action of a pressurizing pump, gets mixed with the pressurized air and then enters into the air-bearing system through utilizing the remaining pressure. The gas-water solution is dispersed into the small and equable drips through a dissolved gas releaser, and the drips drive the suspending substances and the colloidal substance to float up to the water surface so as to achieve the removal. The water coming out of the middle pond enters into the filter to remove the small suspending substances and enters into the ozone/active carbon filtering system so that the reaction of the ozone basic chain is caused under the action of the active carbon, thereby speeding up the decomposition of the ozone into OH and other free radicals, degrades a small amount of organism, eliminates the color and finally ensures that the outtaken water reaches the recovery standard of the printing and dyeing sewage.
