摘要
考察了高速给水曝气生物滤池预处理西江微污染原水的中试启动情况。试验表明,对于西江原水,高速给水曝气生物滤池在启动12 d后,滤池挂膜成功,氨氮去除率稳定在60%左右;COD的去除率在20%左右;气水体积比为0.1:1;采用气水联合方式进行反冲洗。系统启动稳定后,氨氮、CODMn等指标出水完全符合生活饮用水卫生标准(GB 5749-2006)要求。
This study investigated the start-up of high-rate UBAF pretreating for micro-polluted raw water of Xijiang River. The results showed that mature biofilm was formed in the filter after 12 days. The removal efficiency of ammonia nitrogen, COD achieved about 60% and 20%, respectively. And the gas water ratio was 0.1：1. Backwashing was conducted by air-water combination flush. When the system was operated steadily, the level of ammonia nitrogen, CODMn and other index could well meet the national standards for the daily drinking water quality（GB 5749--2006）.
