本文以最大容积有效利用率为考察指标,在相同膨胀高度和相同回流量条件下,用正交试验和数理统计的分析方法,对下向流布水装置的结构组合型式进行了优化试验研究。得到了布水装置工况影响因素的重要性顺序和显著性因素,以及最佳布水装置的结构组合型式。

In this paper,with the object of maximum usefulvolume effieiency,the optimization of structures of downflow wastwaterdistributors in an anaerobic fluidized bed under the condition of sameexpansion height and same return flow rate is studied by means oforthogonal test and statistical analysis.The sequence of importance ofthe factors affecting the performance of the distributors is given andthe optimum structure of downflow wastewater distributors is obtained.
