摘要
对影响固定化颗粒密度的几种因素进行探讨,结果表明,增大污泥的比例、氯化钙浓度及减少颗粒粒径都能提高固定化颗粒的密度,提出了几种改善固定化颗粒密度的方法,改用氯化钡作为固定溶液或加入砂子、活性炭等物质能够有效地增加固定化颗粒的密度。
It was discussed that several factors influencing the density of immobilized beads.The results showed increasing the proportion of sludge,changing the concentration of calcium chloride and reducing the diameter of particles,all could increase the density of immobilized particles;altering barium chloride as immobile solution,adding materials such as sand or activated carbon etc.could effectively increase the density of immobilized particles.
