| 简介 |
PURPOSE : A sewage/wastewater treatment facility and a method thereof are provided to prevent sludge deposition, and to have excellent aerobic degradation efficiency as the oxygen dissolution by aeration is possible in the whole aerobic digestion bath.CONSTITUTION : A sewage/wastewater treatment facility comprises an aerobic digestion bath(110) and a pressure port(112). The pressure port re-dissolves ammonia gas which is generated in the oxidation by the pressure control within the aerobic digestion bath in source water, to control the pH through controlling the collection amount of air and ammonia gas within the aerobic digestion bath. Multiple diffusers which are able to increase the unit pressure by injecting air or ammonia gas in multiple positions are installed in the aerobic digestion bath. The diffuser comprises a first diffuser(120) which is installed in the lower part of the aerobic digestion bath and injects air, and a second diffuser(130) which is installed in the upper part of the aerobic digestion bath and injects air and ammonia gas.COPYRIGHT KIPO 2013 |
