CONSTRUCTION FOR PURIFYING AND CONTROL OVER QUALITY OF DRAINAGE WATER Russian patent published in 2009 - IPC C02F9/14 C02F3/32 

FIELD: mining.

SUBSTANCE: construction is built on module base and consists of supplying channel with water distributing structures, of biochemical purification block in form of capacity with higher water vegetation equipped in its bottom part with drains, of aeration block, of block of chemical melioration of purified water, of sorption purification block, and of outlet channel with structures. At inlet and outlet the blocks of bio-chemical and sorption purification are hydraulically connected with the supplying and draining channels by means of channels and structures. The construction is also equipped with a station of regeneration of sorption filters, with a basin-receiver for growing seedling of higher water vegetation, with platforms for utilisation of residues of higher water vegetation, with points of control over chemical composition and quality of water, with a cut-off drainage, with a distributing channel with water distributing structures and with not less, than one module element of purification. The module element of purification consists of the block of sorption purification, of the block of biochemical purification, and of the aeration block of purified water within the ranges of the biochemical purification block.

EFFECT: increased efficiency of drainage water and expanded functions of construction.
