PLANT FOR MICROBIOLOGICAL TREATMENT OF EFFLUENTS Russian patent published in 2013 - IPC C02F3/30 

FIELD: process engineering.

SUBSTANCE: invention may be used for biological cleaning of industrial and household effluents. Proposed plant comprises housing 1 consisting of two parts. Housing top part is shaped to cylinder or truncated cone, or truncated pyramid with degressive angle of inclination to change in bottom section as a cone or pyramid with degressive angle of inclination. Housing 1 doubles as second settling section 11. Housing 1 accommodates bafflement chamber 2, water anaerobic treatment chamber 4, water aerobic treatment chamber 7 and chamber 10 including second settling section 11. Said water anaerobic treatment chamber 4 includes first settling section 5 with thin layer settling unit 6. Said water aerobic treatment chamber 7 is equipped with aeration system 9 and carriers 8 for immobilisation of microorganisms Chambers 2 and 4 are separated by perforated baffle 17 while baffle 18 is arranged between chamber 7 and 10. Outlet of initial effluents feed pipeline 3 is provided with impingement baffle 22 shaped to ring.

EFFECT: complete cycle of high-quality of cleaning, compact design, higher stability and mobility in operation.
