Experimental Study on Activated Sludge Form Sewage Treatment of Different Oxygen Gradient Reactor

Abstract:

Article Preview

It used dissolved oxygen meter to detect dissolved different oxygen concentration within wastewater treatment reactor and analysed reasons for the formation of oxygen concentration gradient. In order to learn more about activated sludge form of different oxygen gradient in the reactor, biological microscope operated in characteristics of microfauna and activated sludge floc in the reactor has been studied. The results showed that Vorticella and Rotifera could grow normally in the high and low regional areas; there are more abundant micro-fauna species in the area of low oxygen, and the microfauna was more mature than those in the area of high oxygen; activated sludge was brown and floc size was small in the areas of high oxygen, activated sludge was black and floc size was big.
