| titleOfInvention | Advanced treatment apparaters and method of sewage water by flow distribution ratio. |
| abstract | The present invention relates to an advanced treatment apparatus and method for highly removing nitrogen and phosphorus in sewage or wastewater by biological treatment method by predominantly prescribing specific microorganisms for each process in a sewage treatment plant or wastewater treatment plant and precisely establishing the necessary conditions.n n n The present invention utilizes different growth and growth conditions of microorganisms involved in anaerobic and aerobic and denitrification and uses submerged biofilm devices to achieve mass retention by predominantly attaching and attaching specific microorganisms and accurately maintaining the required nitrification rate. It is to effectively remove nutrients such as organic matter and nitrogen, and to obtain stable treated water quality even if the sewage inflow flow rate is changed by the sludge replenishment device and operation sequence water control.n n n To this end, an anaerobic tank is installed at the front of the process, and a submerged biofilm device is installed to mass-proliferate microorganisms suitable for anaerobic conditions to remove organic matter in anaerobic state, and then, an aerobic tank is installed to supply air and remove residual organic matter. And oxidize the ammonia and organic nitrogen in the sewage to nitrous acid, but about 56% of the sewage from the first anaerobic tank flows into the aerobic tank and about 44% is sent directly to the anaerobic denitrification tank installed after the aerobic tank. 56% of the ammonia in water is completely oxidized to nitrous acid. In the next anaerobic denitrification tank, a submerged biofilm is installed to mass-proliferate microorganisms suitable for anaerobic depletion of organic matter, converting ammonia and nitrite directly to nitrogen gas to remove most nitrogen, and NO₃) is denitrified in the anaerobic tank by internal return, and the sludge of the final sedimentation basin is returned to the anaerobic tank to maintain the required MLSS. It is an advanced treatment apparatus and method for treating sewage, which oxidizes and maintains ammonia as nitrous acid easily, accurately and stably, and also provides organic substances in sewage with lower C / N ratio and nutritional substances such as nitrogen and phosphorus. Can be removed effectively and the transportation cost and air supply amount is small This reduces the energy costs required for the treatment, eliminates the odor of the sludge and eliminates the odor, and provides stable discharge water quality against fluctuations in the influent sewage. |
