Process for the biological purification of waste water |
摘要 |
In a process for the biological purification of waste water by mixing a sludge-water mixture and air in an activation chamber charged continuously with waste water, activated sludge and air and from which an equivalent quantity of sludge-water mixture is discharged, the sludge-water mixture is guided along with the air in the activation chamber so as to define at least one loop shape motion. In a further embodiment of the process that part of the sludge-water mixture that does not continue its loop shape course is submitted to a biological after-reaction, preferably occurring in the activation chamber, while avoiding backmixing with the mixture in loop shape motion.
