摘要：

A single basin biological denitrification system with alternative aeration is an excellent system which consists of simple components and performs flexible operation. Usually indirect parameters such as DO or ORP etc. have been used to control denitrification reactors. The authors tried to monitor NH4-N in a reactor by using a newly developed automated analyzer combined with UF sampler. Then the authors tried to control the operation of a denitrification reactor by using fuzzy inference. The fuzzy control system infers a suitable condition from multi variables (NH4-N, DO, ORP and pH) obtained in an actual process. The direct ammonium control system using fuzzy inference performed quick response and high nitrogen removal with stability and easy maintenance.
