FIELD: processes.

SUBSTANCE: invention relates to the field of sanitation, particularly to pumping systems undehydrated sewage sludge which may be generated fermentation gases. System includes pumping precipitation tank (1) with supply conduit (2) at least one pump (3) with suction and discharge conduits (4, 5). System is further provided with discharge line (6) and air-hydraulic column (7) is formed as vertical tube (8) with upper and lower plugs (9, 10) are hermetically welded respectively to the lower and upper parts of pipe (8), with nozzles (11, 12) respectively, a supply source of precipitation and removal degassed sediment at the bottom of tube (8), above lower plug (9), and with nozzle (13) outlet gases degassing connected to top flap (10). Top cap (10) is located above the level of sediment in tank (1). Discharge line (6) connects reservoir (1) with nozzle (11) supplying the initial precipitation of column (7). Suction pipe (5) of pump (3) connected to nozzle (12) diverting degassed precipitation tower (7).

EFFECT: invention is aimed at expanding the scope, as it allows to pump fermented sludge.
