Description
(54) СПОСОБ ОБЕЗВРЕЖИВАНИЯ ГИПОХЛОРИТСОДЕРЖАЩИХ(54) METHOD FOR CLEANING HYPOCHLORITE-CONTAINING
СТОЧНЫХ водWastewater
Изобретение относитс к технологни очистки сточных вод, содержащих гипохлорит кальци , котор е образуютс на предпри ти х химической промышленности и цветной металлургии , получакнцих или примен ющих хлор и его соединени . Разработка эффективных и экономических методов очистки этой группы сточных вод весьма актуальна, так как по действующим нормам в воде водое юв должен полностью отсутствовать активный хлор и ограничиватьс содержание хлор-иона 300 7Л.The invention relates to a wastewater treatment technology containing calcium hypochlorite, which is formed in the chemical industry and non-ferrous metallurgy, which is obtained or used with chlorine and its compounds. The development of effective and economic methods for purification of this group of wastewaters is highly relevant, since, according to current standards, the water of the southeast should completely lack active chlorine and limit the chlorine ion content to 300L.
Наиболее близким по технической сущности и достигаемс ну результату вл етс способ обезвреживани гипохлоритсодержащих сточных вод путем обработки сол ной кислотой flj.The closest in technical essence and the result is achieved is the method of disposal of hypochlorite-containing waste water by treatment with hydrochloric acid flj.
В основе способа лежит химическа реакци The basis of the method is a chemical reaction
Ca(OCI)- + 4НСг- СаСе2. + + + 2сеа..2Ca (OCI) - + 4НСг- СаСе2. + + + 2sea..2
Дл осуществлени этого способа требуетс сол на кислота. Образующийс хлор улавливают. Сточные воды , в которых остаетс некоторое количество активного хлора и свободной сол ной кислоты, очищак)Т химическими методс№1И, например известн комThis process requires hydrochloric acid. The chlorine produced is trapped. Wastewater, in which a certain amount of active chlorine and free hydrochloric acid remains, is purified by chemical methods No. 1, for example, limestone
и сульфитом натри , отдел ют осадок а сточные воды, содержащие хлорида, сбрасывают в водоекы. На тех предпри ти х титано-магниевой промышленности , где примен ют этот метод, остающийс - в сточных йодах 0,8-1 г/л гипохлорита кальци восстанавливают дефицитным тиосульфатом натри и после отделени шлсша сточные воды and sodium sulfite, the precipitate is separated, and the waste water containing chloride is discharged into water treatment plants. In those enterprises of the titanium-magnesium industry, where this method is used, the remaining - in waste iodine, 0.8-1 g / l of calcium hypochlorite is reduced with deficient sodium thiosulfate and after separation of waste water.
10 направл ютс в водоем, загрйзн его.10 are sent to a reservoir, loading it up.
Недостаток известного способа состоит в сложности процесса изгза его многостадийности, применени The disadvantage of this method is the complexity of the process because of its multistage, application
15 дорогосто щего дефицитного реагента - тиосульфата натри , невозможности получени товарного продукта.15 expensive deficient reagent sodium thiosulfate, the inability to obtain a marketable product.
Целью изобретени вл етс уп The aim of the invention is a pack
20 рощение процесса и возможность пол чени тов арного продукта.20 process growth and the possibility of obtaining products of the ary product.
Поставленна цель достигаетс способом обезвреживани гипохлорнт содержавших сточных вод путем обра25 ботки сол ной кислотой, в котсфом гипохлоритсодержащие сточные воды обрабатывают промыишенными газами, содержа111ими пары хлористого водорода , до содержани сол ной кисло30 ты 10-50 кг/л, и процесс ведут приThis goal is achieved by the method of neutralization of hypochlorite containing sewage by treatment with hydrochloric acid, in the case of hypochlorite-containing waste water is treated with industrial gases containing hydrogen chloride vapor to a content of hydrochloric acid of 10-50 kg / l, and the process is carried out at
