摘要
电气石是一种价格低廉容易获取的天然矿物。做为一种具有独特表面特性的矿物材料,在水处理领域具有广阔的应用前景。文章针对生物浮动床,对其添加电气石前后对焦化废水的降解特性进行了研究,结果表明,在系统中添加电气石可以有效的提升生物浮动床(MBBR)对化学需氧量(COD)的去处效果。由于电气石自然电极的存在,可以促进废水中有机物的降解,同时,通过显微镜观察可以发现,电气石还可以成为生物载体,提升反应器的处理效果。
Tourmaline is a kind of natural low-cost mineral material. It has a number of unique physical properties and has been a kind of promising environmental material in wastewater treatment. This study was to investigate the aerobic biofilm treatment of coking wastewater with and without tourmaline addition. The results indicated that tourmaline added in moving bed bioreactor （MBBR） process could enhance the removal efficiency of chemical oxygen demand （COD）. The organic contaminants could be removed by tourmaline added. The mechanisms of increase of organic contaminants removal may correlate to the existence of toumlaline spontaneous electrode. Micrograph of the excess sludge in the tourmaline-MBBR system indicated that the toumaaline added could be the carrier of the microbe and also affect the biomass and pollutant removal.
