摘要
目的研究海水养殖废水消毒效果,确定最佳消毒工艺技术。方法通过模拟海水消毒试验,比较次氯酸钠、二氧化氯、碘伏、戊二醛等4种消毒剂对海水中细菌杀灭效果。结果在海水废水中投加二氧化氯8 mg/L,作用10 min,可使海水养殖废水中异氧菌数下降至0 cfu/ml。二氧化氯投加量为6 mg/L,作用10 min,可使海水养殖废水中海洋弧菌数下降至0 cfu/ml。结论在所试验的4种消毒剂中,以二氧化氯杀菌效果最好,对环境污染轻微。
Objective To research the maricuhure wastewater disinfection effect, and to determine the best disinfection technology. Methods Simulated seawater disinfection test was used to compare bacteria killing effect of sodium hypochlo- rite, chlorine dioxide, iodine volts and glutaraldehyde. Result Waste seawater with chlorine dioxide 8 mg/L for 10 min, can make the heterotrophic bacterium number in maricuhure wastewater drop to 0 cfu/ml. Chlorine dioxide 6 mg/L for 10 min can make Marine vibrio number in maricuhure wastewater drop to 0 cfu/ml. Conclusion In the test of 4 kinds of disinfectant, disinfection effect of chlorine dioxide is the best., which has slight pollution to environment.
