EQUIPMENT FOR THE MULTI-STAGE PURIFICATION BY ACTIVATED SLUDGE OF SEWAGES, PARTICULARLY COMMUNAL SEWAGES, CONTAINING ORGANIC IMPURITIES

摘要

The proposed equipment comprises aeration space, aerator equipment, settling space, guide plates, and inlet and outlet connections. It is based on at least two basins (R1,R2..RN) connected in series by the opening (3). This opening (3) is at the same height as the inlet (1) and outlet (2) connections. Guide plates (7,8,9) are located in the vicinity of the transfer (3) and outlet (2) connections. The aeration spaces (10) of the basins (R1,R2..RN) are formed between the inlet opening (1) and the guide plates (7,8,9). The settling spaces (11) are formed between the guide plates (7,8,9) and the outlet opening (2) or the transfer opening (3) a source of compressed air is connected to the air supply system (12)
