利用网袋、浮器、枯草芽胞杆菌、缓释培养基有机组合成固定化枯草芽孢杆菌净化器.通过36 d的试验，结果显示固定化枯草芽孢杆菌净化器组水体pH稳定，化学需氧量( COD)降低33.5%，氨氮降低，亚硝态氮未升高，硝态氮保持恒定；固定化枯草芽孢杆菌净化器组池塘中异养菌总数未出现明显升高，弧菌数量差异不显著，芽胞杆菌数量增加.养殖鱼类增重率显著高于对照组.固定化枯草芽孢杆菌可以起到良好的调节水质效果，有效时间长，成本低.

The experiment was conducted to study the effects of immobi1ized Bacillus subtilis purifier, which consists of mash bag, f1oating device, B. subtilis, and sustained re1ease medium, on the purification of aquacu1ture water. After 36-d experiment, the pH va1ue of water was kept stab1e, whi1e the chemica1 oxygen demand ( COD) was decreased by 33. 5%as compared to the contro1, the ammonia nitrogen content was 1owered, and nitrite nitrogen content and nitrate nitrogen con-tent remained stab1e. The tota1 heterotrophic bacteria1 counts, the number of vibrios stayed steady, and the B. subtilis counts were increased. The fish weight gain in immobi1ized B. subtilis purifier treatments was higher than that in contro1. It is suggested that immobi1ized B. subtilis purifier cou1d improve water qua1ity for a 1ong period of time at a 1ow cost.
