摘　　要：生物流化床是一种高效的、适应性广的新型污水处理技术,它是一个分布参数、非线性、时变、大滞后和多变量耦合的复杂系统,难以建立精确的数学模型,生物流化床的自动控制已经成为其推广的重要障碍之一。本文在简要介绍生物流化床污水处理技术的工艺特点及发展状况基础上,着重从控制方案、策略方面对其他流化床的控制方法进行总结,并提出生物流化床控制思路,最后分析生物流化床的发展前景,针对目前生物流化床存在的问题,提出未来的发展方向。Biological fluidized bed （BFB） is a new technology of sewage disposal with highly efficient and wide adaptability. BFB is a complex system of distribution parameters, nonlinear, time-variation, strong delay and multivariable coupling. It＇ s hard to build a precise mathematic model and the automatic control of BFB has become the main obstacle for its commercial application. The technological characteristics and the development status of BFB were introduced. Scheme and strategy of other control were summarized emphatically and the control thinking was proposed. Finally, the future of BFB is analyzed and the direction of development is pointed out according to the current problems of BFB.
