摘要
自行设计了一台小型外循环生物流化床,并研究了该流化床处理垃圾渗滤液启动过程中,载体填充率、曝气量、水力停留时间(HRT)和进水碳、氮质量比(C/N)对椰壳活性炭载体表面生物膜形成的影响。结果表明,挂膜启动过程中较合适的条件为载体填充率5%(体积分数)、曝气量80L/h、HRT 8h、进水C/N 8~10。
An experimental external biological circulating fluidized bed was designed. The effects of carrier fill rate,aeration rate,hydraulic retention time （HRT）,C/N （mass fraction） on the formation of biofilm on coconut shell active carbons during the start of the reactor were studied. The results showed the suitable condition of the start was 5% （volume fraction） carrier fill rate,80 L/h aeration rate,8 h HRT and 8-10 C/N of the influent
