Description

Дл  осугаествлени  способа в обра батываемый сток ввод т шлам водоподготовки и известковое молоко. Выпавший осадок отфильтровывают, очишенную воду сбрасывают.To rationalize the process, water treatment sludge and milk of lime are injected into the treated drain. The precipitate is filtered off, the purified water is discarded.

Пример. В 1л стока вискозного производства, содержащего 500мг серной кислоты, 5 г сульфата натри  и 30 мг цинка ввод т 100 мг шлама водоподготовки в пересчете на сухое вещество и известковое молоко до рН 8,0. Вьшавший осадок отфильтровывают через фильтр загруженный кварцевым песком с размером зерен 0,82 ,0 мм. Осветленную воду с рН 8,0 сбрасывают в водоем.Example. In 1 liter of viscose production containing 500 mg of sulfuric acid, 5 g of sodium sulfate and 30 mg of zinc, 100 mg of water preparation sludge is calculated based on the dry matter and milk of lime to a pH of 8.0. Inserted sediment is filtered through a filter loaded with quartz sand with a grain size of 0.82, 0 mm. The clarified water with a pH of 8.0 is dumped into the pond.

Содержание цинка в осветленной воре не превышает I мг/л.The zinc content in the clarified thief does not exceed I mg / l.
