COMPLEX FOR BIOCHEMICAL TREATMENT AND POST-TREATMENT OF WASTE WATER Russian patent published in 2011 - IPC C02F9/14 C02F3/30 C02F1/28 C02F1/32 C02F1/463 

FIELD: chemistry.

SUBSTANCE: complex for treatment and post-treatment of waste water is in form of a transported container and includes a reservoir divided by partitions into sections and compartments, where the said reservoir has a settling zone, bioreactors with a load for holding biofilms made in form of bio-contactors and rotating galvano-coagulators, whose load is in form of a galvanic pair. The bio-contactors are revolving drums with a load, which are fitted in such a way that they can be immersed into the treated waste water, where the drums of the bio-contactors in the denitrification section are completely immersed, by 20-50% in the oxidation section and by 40-60% in the nitrification section. The secondary settling compartment of the complex there is a floating-bed filter and in the output compartment of the complex there is a sorption filter and a waste water disinfection unit.

EFFECT: high quality of treating waste water and efficiency of the apparatus, simple design of the complex and its high reliability, cutting on size of structures and extent of communication.
