【摘要】 从水处理角度研究了剑水蚤生存和繁殖条件,通过模拟试验发现,水蚤繁殖速度的影响因子依次是:温度>水体营养物>光照时间。剑水蚤的适宜繁殖条件是:CODMn5.8~11.4mg/L、总氮0.53~0.77 mg/L、总磷0.025~0.041 mg/L、水温15~20℃以及光照时间12 h/d。剑水蚤大量孳生的显著征兆是水温15~20℃,通过监测水温变化可以预警剑水蚤暴发,提前采取有效的措施控制剑水蚤污染程度,保障饮用水安全。更多还原

【Abstract】 The survival and reproduction of Cyclops were studied from the point of view of water treatment,the results showed that influencing factors of reproduction rate of Cyclops were:temperature >nutrient in water > illumination time.The suitable condition for the reproduction of Cyclops were:CODMn5.8 to 11.4 mg/L,total nitrogen 0.53 to 0.77 mg/L,total phosphorus 0.025 to 0.041 mg/L,temperature 15 to 20 ℃,illumination time 12 h/d.Significant signs of a large number of breeding was temperature at 15 to 20 ℃.Detection of temperature variation could alarm the outbreak of Cyclops,effective measures could be taken in advance to control the degree of contamination in order to ensure drinking water safety.更多还原
