生物滤塔处理VOCs的挂膜启动方法研究

Study on the Start-up of Biotrickling Filter for Treatment of Volatile Organic Compounds

通过中试规模的生物滤塔的两种填料挂膜方法的试验研究 ,表明填料接种后可以直接装入生物滤塔 ,进行直接通气挂膜 ,该方法符合生物膜在载体表面的固定机理和形成过程 ,可在较短的时间内完成系统启动。

Through the test for biofilm developing measures on two types of medium in pilot-scale , a conclusion is drawn that medium are packed into biotrickling filter and ventilated directly after vaccination, which accords with fixation mechanism and formation process of biofilm developing on the surface medium.The system can be started up by using this method in short time.Some influencing factors on biofilm developing are discussed.
