Description
Известные способы очистки сточных вод от соединений ртути не вл ютс удовлетворительными, а технологичесюс схемы очистки, ирнмер, с нрнменеиием катионитовых фильтров очень громоздк; н прИтом не дают эффективной очнсткн сточных вод.The known methods of purification of wastewater from mercury compounds are not satisfactory, and the technological purification scheme, irnmer, with the implementation of cation-exchange filters is very cumbersome; At the same time, they do not provide effective waste water.
Предлагаемый способ устран ет указанные недостатки и основой на соосажденин сернпсто| .овместно е с 1ьфидами других т желых металлов, например цинка или железа, дл чего к очнщаемоГ воде добавл ютс избыток сернистого соединени , нлиримср гидросу.1ьфида натри , растворенного в воде, ii соль т желого .еталл ..The proposed method eliminates these drawbacks and the basis for the co-precipitation of soaps | in conjunction with 1fides of other heavy metals, such as zinc or iron, for which an excess of sulfurous compound is added to the water, and a sodium hydroxide dissolved in water is added, ii the salt of heavy metal.
Последн добав.т етс в таком количестве, чтобь: обеспечшь полное осаждение сульфид-иоиа и тем самым воспре: тс1В(1в;ггь переходу сернистой ртути в раствор с o6pa30BaHHeN комплекс1;о.о нона .. Отличительна оеобенноеть способа состоит в том, что СТОЧНУЮ воду o6pa6aTbiBaiOT последовательно пли одновременно раетвором серн1 стого соединени п растворол соли т желого металла , например железа или цинка.The latter is added in such an amount as to: ensure complete precipitation of sulphide gas and thus play: mc1B (1c; the transition of sulfurous mercury into the solution with o6pa30BaHHeN complex1; o.on non. The distinctive factor in this method is that SECOND water o6pa6aTbiBaiOT is sequentially or simultaneously a solution of the sulfuric compound and dissolves a salt of a heavy metal, such as iron or zinc.
