【摘要】 为比较分析不同类型机械增氧效果,选择扬水水车式、微管鼓风式、涡轮叶片式和扬水喷水式4种增氧机械,采用滴定法测定开机前后养鱼池塘溶氧量,用养殖种类、增氧时间校正,同一时间内,单位功率的产氧量分别是3953.42、735.66、616.58、177.55/(g/kw.h),扬水水车式显著高于其他增氧方式产氧量。更多还原

【Abstract】 In order to analyze the oxygen producing effects of different aerators,4 types of aerators including waterwheel aerator,microtubule blower,impellor aerator and water jet aerator were selected.By adopting titration,the dissolved oxygen contents before and after these aerators’ operation were determined,and the values were corrected with cultured species and the time of aeration,and the oxygen production was 3953.42 g/kw·h,735.66 g/kw·h,616.58 g/kw·h,and 177.55 g/kw·h,respectively,among which the waterwheel aerator produced more oxygen than other 3 aerators.更多还原
