(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД КРАСИЛЬНЫХ ПРОИЗВОДСТВ(54) METHOD FOR CLEANING WASTE WATERS OF COLORFUL INDUSTRIES
Изобретение относитс к способам очистки сточных вод красильных производств и может быть использовано дл очистки стоков, образующихс , н пример, при производстве красителей и полупродуктов, чернил, цветной ту Известен способ очистки сточных вод красильных производств, в частности , от кубовых красителей путем электролиза с использованием анода из двуокиси свинца и при плотности тока 1,6-2,5 А/дм2 1. Однако такой способ очистки хара теризуетс значительным расходом электроэнергии, продолжительностью обработки, пассивацией анодов, а та же необходимо проводить затем доочи ку сточных вод. Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ очистки сточных вод красильных производств, заключающийс в электролизе с исполь зованием титановых анодов, покрытых окислами рутени и титана, в присутствии хлор-ионов при плотности тока 1-2 А/дм2 2. Однако дл получени приемлемой степени очистки требуетс продолжительность обработки 15-25 мин. Кроме того, остаточна концентраци активного хлора составл ет более 600 мг/л, поэтому требуетс дехлорировагтие очищенных сточных вод перед выпуском их в канализацию. Целью изобретени вл етс сокращение продолжительности обработки и снижение остаточной концентрации актив ного хлора. Это достигаетс тем, что электролиз сточных вод провод т с нерастворимым титановым анодом, покрытым окислами рутени и титана, в присутствии хлор-ионов, при плотности тока 1-2 А/дм и при одновременном ультрафиолетовом облучении. Отличием вл етс использование одновременно с электролизом ультра-фиолетового облучени . Сущность способа состоит в том, что в процессе-электролиза сточикк вод из-за разр да на аноде хлор-ионов образуетс активный хлор, который вл етс основным окисл ющим агентом при деструкции органических красителей и поверхностноактивних вецести. Ультрафиолетовое облучение увеличивает полноту и скорость реакстП оь-щ-лени образую{цимис при элокт} -лиус активным хлором и кислородом.The invention relates to methods for treating wastewater from dye plants and can be used to clean wastewaters, for example, in the production of dyes and intermediates, inks, colored ones. A known method for cleaning wastewater dye plants, in particular, from bottom dyes by electrolysis using anode from lead dioxide and at a current density of 1.6-2.5 A / dm2 1. However, this cleaning method is characterized by significant power consumption, processing time, passivation of the anodes, and the same necessity to spend then doochi ku wastewater. The closest to the invention according to the technical essence and the achieved result is the method of wastewater treatment of dye plants, which consists in electrolysis using titanium anodes coated with ruthenium and titanium oxides in the presence of chlorine ions at a current density of 1-2 A / dm 2. However, to obtain an acceptable degree of purification, a treatment time of 15-25 minutes is required. In addition, the residual concentration of active chlorine is more than 600 mg / l; therefore, dechlorination of the treated wastewater is required before it is released into the sewage system. The aim of the invention is to reduce the processing time and reduce the residual concentration of active chlorine. This is achieved by the fact that the electrolysis of wastewater is carried out with an insoluble titanium anode coated with ruthenium and titanium oxides in the presence of chlorine ions, at a current density of 1-2 A / dm, and with simultaneous ultraviolet irradiation. The difference is the use simultaneously with the electrolysis of ultraviolet irradiation. The essence of the method lies in the fact that in the process of electrolyzing the waste water, due to the discharge on the anode of chlorine ions, active chlorine is formed, which is the main oxidizing agent during the destruction of organic dyes and surface active supernatants. Ultraviolet irradiation increases the completeness and rate of reactivity of o-sch-leni, forming {Tsimis with elokt} -lius with active chlorine and oxygen.
