BIOLOGICAL REACTOR Russian patent published in 2013 - IPC C12M1/00 C12M1/04 

FIELD: process engineering.

SUBSTANCE: invention relates to microbiological industry, yeast and alcohol production and is intended for treatment of liquid organic wastes, mainly, manure or excrements to produce pollution-free organic fertilisers and combustible biogas. Proposed biological reactor comprises body with partitions. Reactor body represents a vertical sealed and heat-isolated tank with walls connected by dome or stiff roof to create a space between biomass surface and roof for pre-accumulation of biogas. Tank inner space is divided by partitions in, at least, two sections. Said partitions are installed vertically at the tank center and over bioreactor height and connected with the tank walls. Biomass overflow openings are made in every partition between first section, between midsections and between last section, at lower peripheral part. Bottom of every said section is inclined both from the center to periphery and toward the next section. Every section if equipped with manifold for makeup feed, heat exchanger, mixer, pH and eH gages and temperature gage. First section loading assy is composed of the manifold with shutoff valves for biomass loading while discharge assembly represents the manifold with shutoff valves for discharge of risen biomass. Biomass level gages are arranged at top lateral part of the last section.

EFFECT: higher efficiency, lower costs.
