一般而言，污泥浓度愈大，反应器的最大处理能力也就愈大，因此应使反应器内污泥颗粒化。

In general, the greater the sludge concentration, the maximum handling capacity of the reactor, the greater, should be so granular sludge reactor.

经济曝气强度随污泥浓度的增加呈指数递增；

Economic aeration intensity is exponential increasing with sludge concentration enhancing.
