摘要
膨胀式发泡陶瓷微球是一种新型的特种陶瓷材料。设计了一种简易的过滤装置,初步研究了膨胀式发泡陶瓷微球在污水藻体过滤中的应用。研究表明,利用完整陶瓷微球颗粒作为介质过滤含藻水效果较差,破裂的陶瓷微球瓷块作为介质能取得较好的过滤结果,形态不同的陶瓷微球瓷块混合按大小梯度填充型滤柱的过滤效果最佳。陶瓷微球在藻体过滤中可实现二次利用。藻体过滤效果可通过过滤前后被测水样在485nm波长处的可见光光吸收变化来体现。
Expanded foam ceramic microsphere is a new special ceramic material. This paper designs a simple filtration device, and studies the application of expanded foam ceramic microspheres in sewage algal filtration. The results show that the effect of using intact ceramic microspheres as media to filter algae-laden water is poor. Using cracked ceramic microspheres as media, better filtering results can be obtained. Using cracked ceramic microspheres with different sizes and shapes mix together as media, the best filtering results can be obtained. Ceramic microspheres can be used for two or more times in algae filtration. The effect of algal filtration can be reflected by the changes in visible light absorption of water samples before and after filtration at the wavelength of 485nm.
