ACTIVATED SLUDGE PROCESS FOR THE TREATMENT OF WASTE WATER |
| abstract |
The object of the invention is an improvement to the activated sludge process for the treatment of waste water in which the waste water is introduced into a system of tanks or aeration basins to decompose the organic substances contained in said waste water. by microorganisms in said tank or basin system and said microorganisms are separated from the effluent flowing from an aeration tank while a part of the separated microorganisms is recycled into the tank system or basins. According to the invention, said treatment is carried out in a system of aeration tanks or basins which comprises a first tank, a second tank and a third tank (or basins), into which said waste water and said micro- organisms in the first tank, while the aeration rate in the first tank is 0.5 to 0.8 volume / minute relative to the amount of liquid in said first tank, the aeration rate in the second tank is 0.1 to 0.4 volume / minute based on the amount of liquid in the second tank and the aeration rate in the third is 0.1 to 0.3 volume / minute based on the amount of liquid in the third tank. |
