The effect of various operating variables such as initial inoculum circulation, dilution rate, chemical oxygen demand (COD) loading rate, and quantity and quality of inoculum on the process of film formation on sand surface and reactor performance were studied using synthetic glucose based wastewater. It was found that the film formation process is favored by a high dilution rate, a large quantity of inoculum, and an inoculum having high methane producing capacity. Experimental observations indicate that the biofilm formation process is initiated by methanogenic bacteria.
使用基于合成葡萄糖的废水,研究了各种操作变量,如初始接种物循环、稀释率、化学需氧量(COD)负荷率以及接种物的数量和质量对砂表面成膜过程和反应器性能的影响。结果发现,高稀释率、大量接种物以及具有高甲烷产生能力的接种物有利于成膜过程。实验观察表明,生物膜形成过程由产甲烷细菌启动。
