纤维球

Then , the paper suggested that the good mashan manganese grain with strong adsorption has a better effect on removing fe ( superscript 2 + ) and mn ( superscript 2 + ) at the same time , while fiber ball and quartz grain are not suitable for removal of mn ( superscript 2 + )
其次，吸附能力较强的优质天然马山锰砂滤料有较好的同时去除铁锰的效果，而纤维球和石英砂则不适宜除锰。
The results showed : fiber ball has the highest efficiency among the three , its water - consumption is small in backwash and it is more wear - resisting ; the comprehensive property of quartz grain filter material is poorer ; manganese grain has an effective removal of fe ( superscript 2 + ) and mn ( superscript 2 + ) but water - consnmption is big
结果表明纤维球滤料除铁滤速高，反冲洗耗水量小且耐磨损；石英砂滤料综合性能次之；锰砂虽然除铁效果较好，但反冲洗耗水量大。
