METHOD FOR SEWAGE PURIFICATION AGAINST ORGANIC DYES

摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 ways of treatment of industrial wastewater and can be used in u043au0440u0430u0441u0438u043bu044cu043du043e finishing production of textile industry. purpose to shorten the process of purification and flow rate of ozone. treatment of waste water containing dye are, "u043fu0440u00a0u043cu043eu0439 red", with the intensity of staining of 1: 500.wastewater treatment by ozone in the reactor u043fu0440u0435u0434u0441u0442u0430u0432u043bu00a0u044eu0449u0435u043c an apparatus is divided into two chambers. u043au0430u0436u0434u0430u00a0 chamber divided u0434u0432u0443u043cu00a0 vertical partitions into three sections alternately disposed upper and lower it. at the bottom of each section are located u0433u0430u0437u043eu0440u0430u0441u043fu0440u0435u0434u0435u043bu0438u0442u0435u043bu0438. the waste water is up to the top of the first section of the first chamber.after that, the waste water is received in the upper part of the first section of the second chamber. the purified waste water u0432u044bu0432u043eu0434u00a0u0442 last section of the second chamber, and u043eu0437u043eu043du043e - air mixture u0432u0432u043eu0434u00a0u0442 second camera in parallel in each section. the gas flow after each section of the second chamber to the first chamber u043du0430u043fu0440u0430u0432u043bu00a0u044eu0442 similar.u0434u043bu00a0 u0441u0440u0430u0432u043du0435u043du0438u00a0 wastewater u043fu0440u043eu0432u043eu0434u00a0u0442 in two reactors, the sum of which is the size of the above reactor with parallel to the u043eu0437u043eu043du043e air the mixture in each. the invention u043fu043eu0437u0432u043eu043bu00a0u0435u0442 achieved 96% of u043eu0431u0435u0441u0446u0432u0435u0447u0438u0432u0430u043du0438u00a0 effect in reducing the dose of ozone from 418 to 340 mg / l and the processing time from 110 to 91 minutes. 2, table 2).
