摘要
鳗鲡工厂化养殖池水经0.5-64 mg/L的高铁酸钾净化后,pH波动〈0.3,DO变化幅度〈4.4%。而悬浮物、COD、氨氮、亚硝酸盐、硫化物浓度等均有不同程度的改善。其中对COD、硫化物、亚硝酸盐的最高去除率分别为75.3%、97.4%、20.6%。同时,高铁酸钾超过5 mg/L可使养殖水体的总菌数下降愈98.7%。
The fluctuation only 0.3 in pH value and less than 4.4% in dissolved oxygen level and low concentrations of suspended solids,COD,ammonia-N,nitrite and,sulfide were found in the aquaculture water after the water was treated with potassium ferrate at a rate of 0.5～64 mg/L.Meanwhile,the COD,sulfide and nitrite in the water were eliminated at a rate of up to 75.3%,97.4% and 20.6%,respectively.The account of total bacteria in water was decreased significantly by over 98.7%,indicating that potassium ferrate was efficient for purification of aquaculture water without side effect.
