摘要
试验结果表明,养殖系统出水水质较进水水质有明显改善。经过100 d的循环水养殖,尼罗罗非鱼的平均体质量由30.34 g增加至120.08 g,平均生长速度为0.89 g/d,存活率为85.6%。
Water pollution and eutrophication as a bottleneck became serious with the development of aquaculture. Zeolite enhanced activated sludge process as an enhanced, which can efficiently remove chemical oxygen demand （COD） and NH4-N ,was applied in a pond of Nile tilapia Oreochromis niloticus culturing for 100 d. It was found that the effluent quality was improved compared with that of the affluent. The fish increased from 30.34 g to 120.08 g of body weight with the average growth rate of 0.89 g/d and survival rate of 85.6 %.
