摘要
目前周进周出二沉池的技术仍然被国外制造商垄断,特别是关于配水渠均匀布水的设计计算方法是国外制造商的专有技术.探讨了两种配水渠参数的计算方法:一种是布水孔的孔径和孔距不变、只改变配水渠的宽度的计算方法;又探讨了一种施工方便、精度容易保证、更实用的计算方法:配水渠宽度线性改变、同时布水孔的孔径和孔距随着孔口淹没出流总水头的变化相应改变,从而实现均匀布水.
The technology for periphery-feed secondary clarifier has been monopolized by the foreign manufacturer, particularly, the calculation method for equally water distributing by influent channel is business secret. In this paper, two calculation methods for influent channel parameters were developed. In the first method, the diameter and pitch of orifices are consistent, and only the width of the influent channel is varied. The author developed another more practical calculation method so that the construction process can be convenient and the accuracy can be ensured. In the second method, the width ofinfluent channel varys linearly, and the diameter and pitch of orifices varys with the variation of gross headwater for submerged outflow orifice.
