摘要
论述了石英砂、日本球和国产球滤料，过滤毛纺废水二级生物处理出水的试验情况。结果表明：纤维球的滤速可高达３０～４０ｍ／ｈ，而砂滤速只有９ｍ／ｈ左右；纤维球过滤的运行稳定，砂滤层则易堵塞；和日本纤维球相比，国产纤维球的出水水质较好些，滤阻较大。
This article describes the filtration of woolen mill wastewater through silicon sand and fiber-ball meddium. The results show that,the filtration velocity may be up to 30-40m/hr. through fiber-ball and is only gm/hr. through sand. The fiber-ball filtration is very steady while the sand bed is easy to be blocked up. Compared with Japanese fiber-balls,the Chinese ones can produce some what better effluent but with higher head loss.
