Abstract

FIELD: water purification. SUBSTANCE: invention relates to treating natural and waste waters with no formation of concentrates requiring additional treatment and disposal. Method consists in introducing reducing agent into water followed by reducing nitrates and nitrites on catalyst, wherein, as reducing agent, ferrous ions and, as catalyst, supercarbon are utilized. Reducing agent may be introduced by way of adding water into anode space of electrolyzer with iron or carbon steel electrodes. EFFECT: simplified process.

Изобретение относится к области очистки природных и сточных вод. в частности, от нитратов и нитритов без образования концентратов, требующих дополнительной обработки и утилизации. Способ очистки воды от нитратов и нитритов заключается во введение в воду восстановителя с последующим восстановлением нитратов и нитритов на катализаторе, при этом в качестве восстановителя используют ионы двухвалентного железа, а в качестве катализатора, - суперуголь SС-1, Введение в воду восстановителя может производиться путем подачи воды в анодное пространство электролизера, электроды которого выполнены из железа или углеродистой стали.The invention relates to the field of purification of natural and waste water. in particular, from nitrates and nitrites without the formation of concentrates that require additional processing and disposal. The method of purifying water from nitrates and nitrites consists in introducing a reducing agent into the water, followed by reduction of nitrates and nitrites on the catalyst, using ferrous ions as the reducing agent, and SC-1 supercarbon as the catalyst. The reducing agent can be introduced into water by water supply to the anode space of the electrolyzer, the electrodes of which are made of iron or carbon steel.
