(54) СПОСОБ ОЧИСТКИ ВОДЫ ОТ СЕРОВОДОРОДА(54) METHOD FOR CLEANING WATER FROM HYDROGEN

Изобретение относитс  к об асги технологии очистки природных и сточных Вод, а более конкретно к очистке от сероводорода подземных вод, используемых дл  целей водоснайкени , и сточны вод предпри тий нефтеперерабатывающей промышленности, производства вискозного волокна и т. д., содержащих в своем составе сероводород. Известен способ очистки воды от сер водорода аэрацией боздухом 1 j . Недостатком этого способа  вл етс  то, что дл  достижени  необходимой ст пени очистки требуетс  подкис ленке обрабатываемой Воды до рН 5. При этом весь сероводород переводитс  в молекул рный Н 5 и выдуваетс  в еггмосферу . Этот способ очистки воды от серово дорода св зан с загр знением воздушного бассейна токсичным сероводородом. Наиболее близким к изобретению по технической сущности н достигаемому результату  вл етс  способ, заключающийс  в аэрации очищаемой воды кислородом воздуха в присутствии солей желе за. При этом образуетс  трудноосаждаемый сульфид железа, дл  удалени  которого требуетс  увеличение объема очистных сооружений. Расход солей Fe (П) по этому методу составл ет 3,3 мг на , 1 мг HjS . Аэрацию производ т при атмосферном давлении. При обработке вока этим способом достигаетс  степень очистки вода от сероводорода до 95%. Дл  У|Далени  остаточного сероводорода в технологической схеме предусматриваетс  хлорирование обработанной воды 2. Целью изобретени   вл етс  повышение степени очистки воды. Поставленна  цель достигаетс  тем, что в способе очистки воды от сероводорода аэрацией воздухом в присутствии солей железа аэрацию производ т после подщелачивани  воды до рН 7,5-8,5. Соли железа преимущественно ввод т из расчета 1,5-2,0 мг (П) на 1 мг Н 5 , а аэрацию осуществл ют при давлении 0,4гО,5 МП а.The invention relates to asgi technology for the purification of natural and waste waters, and more specifically to the removal of groundwater from hydrogen sulphide used for water shedding purposes, and wastewater from enterprises of the oil refining industry, production of viscose fiber, etc., containing hydrogen sulphide. A known method of purifying water from hydrogen sulphur aerating a 1 j jitter. The disadvantage of this method is that in order to achieve the required purification level, it is necessary to acidify the treated Water to pH 5. At the same time, all the hydrogen sulfide is converted into molecular H 5 and blown into the atmosphere. This method of water purification from sulfuric acid is associated with pollution of the air basin with toxic hydrogen sulfide. The closest to the invention to the technical essence of the achieved result is the method consisting in the aeration of the purified water with oxygen in the presence of gel salts. This forms hard-to-build iron sulphide, which requires an increase in the volume of sewage treatment plants to remove. The consumption of Fe (P) salts according to this method is 3.3 mg na, 1 mg HjS. Aeration was performed at atmospheric pressure. When treating wok with this method, the degree of purification of water from hydrogen sulphide to 95% is achieved. For Y | Daleni residual hydrogen sulfide in the technological scheme provides for the chlorination of the treated water 2. The aim of the invention is to increase the degree of water purification. This goal is achieved by the fact that in the method of water purification from hydrogen sulphide by aeration with air in the presence of iron salts, aeration is carried out after alkalizing water to a pH of 7.5-8.5. Iron salts are preferably introduced at the rate of 1.5-2.0 mg (P) per 1 mg H 5, and aeration is carried out at a pressure of 0.4 gO, 5 MPa.
