Description

(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ МЫШЬЯКА(54) METHOD FOR CLEANING WASTEWATER FROM ARZYAK

Известен способ очистки сточных вод отA known method of wastewater treatment from

мышь ка обработкой воды окислшощвм и осаж дающим мышь к реагентом с последующим от/аелением аолученного осадка в доочистксА ВОДЬ желеаосодерЗ ащнм коагул нтом.The mouse is treated with water by oxidization and precipitating the mouse with a reagent, followed by the precipitation of the precipitated precipitate in the water aftertreatment by means of geo-concentration of coagulant.

С целью расширени  ассортШИ та преопагаетс  в качестве реагента вспопьзовать хрОМСодержаший.шлам, пренмушественно oiv ходы хромпикового производства.In order to expand the assortment, it is used as a reagent to use chromium-containing sludge, predominantly oiv, from the high-peak production.

Отходы хромпиковсхго производства соде1 жат соединени  . шестввалентного хрома в ко личестве 0,5-2%, а также доломит, соду и соединени  железа. При обработке воды, СС держащей примеси мьш1ь ка, отходами хрок пикового производства трехвалентный к)ышь к окисл етс  до шестивалентного и соосаждаетс  с образующимис  гидроокис ми.Waste bromine production contains compounds. content of chromium in the amount of 0.5-2%, as well as dolomite, soda and iron compounds. When treating water, the MOP containing impurities, the waste of peak production, trivalent k), the mouse is oxidized to hexavalent and co-precipitates with the resulting hydroxides.

Одновременно идет нейтрализаци  сточной водь1. Последующа  доочистка воды жеаезог содержащими коагул нтами .обеспечивает очистку воды от мышь ка до предельно допустимой нормы.At the same time, the wastewater is neutralized. Subsequent after-treatment of water with coagulant-containing coagulates provides water purification from the mouse to the maximum permissible rate.

Пример, К 25О мл промывной воды сернокислотного производства медеплавильного завода С рН .0,8 и исходным содержанием мышь ка |1О г/л добавл ют 75 -г шлама хромпикового производства. Образовашиук   пульпу перемешивают 30 м при 2О-25 С, после чего фильтруют. Фильтрат имеет рН 6,5 и содержит 40 мг/о . Дл  окончательной очистки от мьши|, ка к фильтрату добавл ют раствор железволго купороса и известковое молоко до рН 9Example, To 25 O ml of wash water of a sulfuric acid production of a copper smelter With a pH of .0.8 and 75 g of a chrom-peak production sludge is added to an initial mouse content of | 1O g / l. The slurry slurry is stirred for 30 m at 2 ° C-25 ° C, then filtered. The filtrate has a pH of 6.5 and contains 40 mg / o. For the final purification of the | |, the solution of iron sulfate and lime milk to a pH of 9 is added to the filtrate.

С аелью обеспечени  более интенсивного окислени  гидрозакисн железа До гидроокиси и достижени  более полного соосаждени  мышь ка раствор барботируют воздухом в течение 20 м. После Отделени  осадка филь рат содержит менее 0,05 мг/л мышь ка. To ensure a more intensive oxidation of iron hydroxide before hydroxide and more complete coprecipitation of the mouse, the solution is bubbled with air for 20 m. After separating the precipitate, the filter contains less than 0.05 mg / l of mouse.
