METHOD OF PRODUCTION OF A SORBENT FOR SEWAGE PURIFICATION Russian patent published in 2005 - IPC

FIELD: methods of production of a sorption material for purification of water.

SUBSTANCE: the invention is dealt with the methods of production of a sorption material for purification of water in particular, with a method of production of a sorption charge on the basis of a natural sorbent. The method of production of a sorbent for purification of sewage provides for comminution of a wood produced from a stump wood extracted from a peat deposit, after which it is separated by fractions and treated with a solution of a mineral acid with consequent stacking the treated reduced wood in a filtering installation. At that in direction of the traffic route of the stream of filtration the sizes of the wood fractions are increasing. The sorbent charge is effective at purification of industrial, household and surface sewage simultaneously from suspended substances, oil products, colloidal - dissolved forms of salts and ions of heavy metals, organic impurities.

EFFECT: the invention ensures production of sorbents effective at purification of industrial, household and surface sewage simultaneously from suspended substances, oil products, colloidal-dissolved forms of salts and ions of heavy metals, organic impurities.
