丝状菌性污泥膨胀及生物选择器控制

The Filamentous Sludge Bulking and the Control of the Biological Selector

论述了利用生物选择器来控制活性污泥的丝状菌膨胀问题,阐述了选择器的作用原理、动力学选择性理论、积累/再生理论、饥饿理论,指出菌胶团的吸附储存能力比丝状菌强得多,从而在选择器中可以大量储存有机物,在后续的曝气池中得到大量的增殖,但选择器无法控制丝状菌M.Parvicella引起的膨胀。

This paper discusses on the problem of controlling the filamentous b ulking of the active sludge by using the biological selectors, analyzes on the w orking principle of the selectors: kinetics choice theory, accumulation/regenera tion theory and starvation theory, and points out that chiefly because of sticki ng storage capability of zoogloea is much more powerful than the filamentous, th e selectors can store a great quantity of the organic matters and get great prol iferation in the subsequent aeration tank, but the selectors can't control the b ulking caused by the filamentous of M.Parvicella.
