Efficiency of Intermittent Baffled Biological Aerated Filter for Domestic Sewage Treatment in Small Towns 间歇曝气折流BAF处理小城镇生活污水的效能研究
Determination of the Maximum Production Capacity of Intermittent Filter 间歇过滤机最大生产能力的确定
Process design scheme and main equipment sizing was introduced, including hydrolysis process of intermittent stirred reactor, the washing by porous ceramic membrane, filtration of membrane press filter and calcinations of dynamic rotating flow calcinator-spin flash dryer, the existent problems were discussed. 介绍了间歇搅拌釜式水解工艺、多孔陶瓷膜洗涤、隔膜压滤机过滤、旋流动态煅烧炉-旋转闪蒸干燥组合煅烧的工艺设计方案和主要设备的选型,对存在的问题进行了讨论。
Through quoting the concept of equivalent non-isopiestic pressure filtering time, the formulas of the optimum operating cycle of intermittent filter were derived. The optimum operating cycle and the maximum production capacity of intermittent filter can be calculated rapidly and accurately by the formulas derived. 本文通过引入当量非恒压过滤时间的概念,导出了间歇过滤机最佳操作周期的计算公式,可以快速准确地计算间歇过滤机的最佳操作周期和最大生产能力,附有计算举例。

Selection of Intermittent Filter and Determination of the Operating Conditions 间歇过滤机的选择和操作条件的确定
Aiming at the domestic intermittent hydrolysis and backwardness of filter process, a new process of continuous hydrolysis to produce dicyandiamide has come true as a result of repeated experiment by our factory, thus making each item of technical index achieve or exceed the design level. 针对国内间歇式水解和过滤工艺技术落后的局面,我厂经反复试验实现了水解连续化生产双氰胺的新工艺,从而使各项技术指标均达到和超过设计水平。
The results are as follows: ( 1) Intermittent operating conditions when the water flow is too large, the ceramic filter clogging. 主要结果如下:(1)间歇操作条件下当废水流量过大时,陶瓷过滤器出现堵塞。
