摘　　要：自清洗式活性生物滤池是一种改良的生物砂滤池,具有投资及运行费用低、脱氮效果好、管理简单等多重优点。本文研究了在不同清洗方式下自清洗式活性生物滤池的过滤效果,实验发现间歇清洗与连续清洗各有优劣:连续清洗不仅能获得稳定高效的过滤效果,SS去除率可稳定在50%以上,而且操作简单运行方便,但从节能方面考虑,开发具有稳定高效运行效果的自动间歇清洗装置是一个好的思路。Self-cleaning activated bio-filter is a modified biological sand filter, which has many advantages, such as low investment and operating costs, good nitrogen removal effect and simple management. The filtration performances with different cleaning methods of self-cleaning activated bio-filter were studied. It found that intermittent cleaning and continuous cleaning both had their advantages and disadvantages, continuous cleaning not only could obtain stable and efficient filtering effect, the SS removal rate could reach more than 50%, but also the operation was simple and convenient. For the aspects of energy saving, developing a stable and efficient automatic intermittent cleaning device was also a good idea.
