新型颗粒移动床连续过滤装置的特性研究
A New Type of Continuous Filtration Device with Particle-moving Bed and its Properties
摘要
Abstract
In order to change the intermittent operation of the traditional fixed bed and reduce energy consumption,a new continuous filtration device with the particle moving bed was developed by integrating cleaning scrubbers,a three-phase separator and the filter“anti-particle size distribution”method. The relationship between the intake rate,the cleaning water rate and the updating rate of the moving bed filter layer were discussed,and the best operating conditions were explored. The results show that the intake rate and wash water rate should have an appropriate ratio in order to ensure the stable operation of the device.When the ratio of gas volume to water volume is 7 to 12,the continuous operation condition is best,and at this time,the moving bed filter layer updates fast.The filter cycle period only needs 12,min. The filter aranges particles in anti-particle size natural distribution,so the particle size decreases from the inlet port to the outlet port. With the increase of proc-essing load,the moving bed has better effluent quality than the fixed bed. HRT and the influent concentration have a great effect on the effluent quality and removal rate.The removing rate of turbidity and COD can reach as high as 88.89% and 83.48%respectively.关键词
