For the purpose of improving water quality, biorotator is loaded with plenty of perforated plastie balls of which inner and outer appearances can adhere with biomenbrane, thus ‘having area increased about one time as with the same makes without the balls and water purifying rate over 80% while compared with the same sized biorotating disk. A long-term experiment has shown that the biorotator is well adaptable for fish farming, resulting in high yield per unit water area and low feed coefficient. Additionally, by means of biorotator the economic efficieney is 2.5-3 times higher than that without bloratator. 相似文献
