Abstract
The invention discloses novel equipment for processing sewage of villages and towns. Diversion partition plates are arranged in the shell of the equipment so as to divide the interior of the equipment into a biological reaction area, a forced circulation area, and a precipitation area. The structure of the sewage process equipment is largely simplified, and the occupied area is obviously reduced. A reflex pump and a jet aerator, which are arranged in the equipment, drive the sewage in the biological reaction area to flow in the forced circulation area at a speed of 1.5 to 3.5 cm/s; under the flowing speed, sludge can carry out self-coagulation to form aerobic granules, the suspended solid concentration in the mixed solution is increased to 6 to 12 g/L, thus the sewage processing efficiency is improved; and moreover, the aerobic sludge is converted into granules to effectively prevent the expansion of sludge.
