Performance and Substrate Inhibition Kinetics Model of Nitritation Process in Inverse Turbulent Bed Reactor
逆流湍动床短程硝化反应器的运行性能及基质抑制动力学模型

The performance of a nitritation inverse turbulent bed(ITB) reactor was tested and the substrate inhibition kinetics characteristics of the reactor were analyzed.The results showed that a rapid reactor startup could be realized within 20 d with a strategy that combined the biofilm attachment method namedprecoating carrier treatmentandrapid suspending sludge discharge,with the feeding strategy namedlow strength,high load.When operated at a hydraulic retention time of 3 h and influent NH 4+-N of 700 mg.L-1,co...
