【摘要】：针对电磁场强化传质和抑制微生物生长现象,基于微生物生长动力学和双电层原理,对电磁场强化传质作用机理进行了理论推导,建立了电磁场作用下微生物污垢生长模型.模型以不同水质、流体流速和管道内壁粗糙度为参数,利用Matlab软件,绘制了仿真曲线,计算出微生物污垢热阻变化趋势和电磁抑垢率.结果表明:电磁场对微生物污垢有较强的抑制作用,该模型能够准确地计算出电磁抑垢率,为电磁抑垢装置的开发和应用提供了理论依据.
[Abstract]:In view of the phenomenon of enhanced mass transfer and inhibition of microbial growth in electromagnetic field, the mechanism of enhanced mass transfer in electromagnetic field was theoretically deduced based on the growth kinetics of microorganism and the principle of double electric layer. The model of microbial fouling growth under the action of electromagnetic field is established. The simulation curve is drawn by using Matlab software, taking different water quality, fluid flow rate and inner wall roughness of pipeline as parameters. The results show that the electromagnetic field has a strong inhibitory effect on microbial fouling, and the model can accurately calculate the electromagnetic scale inhibition rate. It provides a theoretical basis for the development and application of electromagnetic scale suppression device.
