| titleOfInvention | How to reduce organic sludge |
| abstract | PROBLEM TO BE SOLVED: To provide a method for treating organic sewage that solves the drawbacks of the conventional biological dephosphorization method, can significantly reduce the amount of excess sludge generation, and enables stable and high-level phosphorus removal. . SOLUTION: Fine iron oxide fine particles coexist in a first aeration tank for performing activated sludge treatment of sewage, and phosphorus in sewage is adsorbed to and removed from the fine particles, and at the same time, organic sewage is aerobically treated. Thereafter, the slurry discharged from the first aeration tank is settled and separated, the separated water is treated water, most of the concentrated sludge is returned to the first aeration tank, and part of the concentrated sludge is aerated by the second aeration tank. The sludge is reduced by repeating the aeration treatment of the sludge that has been solubilized by ozone oxidation or ozone oxidation, and a small amount of sludge is discharged out of the system together with the iron oxide fine particles that have absorbed phosphorus to reduce the sludge. A method for treating organic sewage in which phosphorus-containing water generated as a result is returned to the first aeration tank. |
