专利汇可以提供Method and apparatus for batchwise activated sludge treatment utilizing rotary disc专利检索,专利查询,专利分析的服务。并且PURPOSE: To increase the contact area with sewage by a rotary disc and to enhance aeration effect, by adding a rotary disc apparatus and a jet aerator to the interior of a recirculation flow type treatment tank.
CONSTITUTION: Sewage is introduced into a treatment tank 1 so as to reach a low water level L immersing about 40% of rotary discs 2a and a rotary disc apparatus 2 is operated at a high speed to adhere a biofilm to the surface of each disc. At the point of time when the purifying capacity of the biofilm was stabilized, a jet aerator 3 is operated to perform nitrating operation. Subsequently, the jet aerator 3 is stopped and sewage is introduced into the treatment tank up to a high water level H perfectly immersing the rotary discs 2a by a sewage inflow apparatus 4 to perform denitrifying treatment. The jet aerator 3 is again operated in the high water level state to perform aeration operation generating the recirculation flow and aeration of sewage in the treatment tank 1. Thereafter, the jet aerator 3 is stopped to generate sedimentation action and supernatant water is extracted through a supernatant water discharge apparatus 5.
