Abstract:

用甘蔗渣和蘑菇堆肥作为生物过滤器的填料,去除空气中的甲苯。生物过滤器长期连续运行,在无营养液和pH缓冲剂加入的条件下,研究了生物过滤器中填料含水量和pH的变化以及甲苯去除效率的变化规律,并对填料中的微生物菌属进行了初步鉴定。运行6个月后,填料含水量从56%降到约20%,pH从7.4降至4.5。生物过滤器可以保持4个月的稳定运行阶段,在甲苯进口浓度100~600mg/m3范围内,甲苯平均去除率在85%。填料内检出青霉、毛霉、曲霉和芽孢杆菌属。生物过滤器的较佳运行条件为:填料pH4.5~7.4,含水量30%~56%。填料含水量低于20%时,生物过滤器的稳定性和甲苯去除能力被破坏。
