BIOREACTOR Russian patent published in 2014 - IPC C02F3/00 C12M1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of biotechnology, in particular to equipment, intended for water purification from ammonium nitrogen, nitrite, nitrate by the biological method and supporting pH at the level of 6.5-7.2, and can be used for the purification of natural and after-purification of sewage waters. A bioreactor contains a case, filled with a filtering charge, pipelines for the supply of initial water and discharge of purified water. Water intake, connected to the pipeline for the discharge of purified water is installed in the upper part of the case. Inside the case placed is a cone, the apex of which is connected to the pipeline supplying initial water, with the cone being installed in such a way that the distance between the case bottom and the lower side of the cone constitutes not more than 10 mm. A cavity between the case and the cone is filled with the filtering charge, representing quartz sand with a fraction from 0.1 to 1.2 mm, and including a possibility of development of a biofilm on it. Water intake is additionally provided with a source of ultraviolet radiation. The source of ultraviolet radiation can be made in the water intake immediately before the pipeline of discharge of purified water.

EFFECT: invention provides an increased efficiency and quality of preliminary water purification with simultaneous simplification of the installation maintenance and reduction of exploitation costs.
