PLANT FOR BIOLOGICAL UTILIZATION OF SEWAGE Russian patent published in 2003 - IPC

FIELD: utilization of sewage. SUBSTANCE: plant for biological utilization of sewage has bioreactor which includes body with technological branch pipes and partitions forming chambers of acid, neutral, alkaline, methane fermentation, collector of sewage from object communicating with acid fermentation chamber, biological filter incorporating case with translucent walls, ultraviolet luminaries placed on outside. Case has lateral perforated partitions forming sections, granular fitting positioned on partitions. Lower section has pump of biological gas, upper section communicates with bioreactor which chambers are equipped with dispersers, methane fermentation chamber communicates with collector of biological fertilizer. Upper section of biological filter communicates with collector of biological methane, biological filter communicates through microfilter with inlet branch pipe of dynamic disintegrator that includes cylindrical body with inlet and outlet branch pipes and cylindrical rotor placed along axis of body and provided with spaced apart holes in its surface interacting with spaced apart holes in body through liquid ring conduit. Disintegrator communicates with upper section of biological cultivator of gold-recovering microflora that includes case with translucent walls and technological branch pipes, ultraviolet luminaries located on outside, lateral perforated partitions forming sections carrying granular fitting made of broken glass. Lower section of biological cultivator communicates with air pump. Plant also has electrolyzer and filter which includes body with technological branch pipes and lateral perforated partition forming collector with bottom mounted on vehicle coming in the form of flat-car. Body is equipped with pump feeding air into collector, is placed on springy supports, is fitted with vibrator. Its filter communicates through solution collector with microfilter and biological cultivator and with electrolyzer. Electrolyzer has body with technological branch pipes, anode and cathode electrodes installed in it. The latter carry coils made of steel mesh. EFFECT: widened technological potential of plant. 2 dwg
