摘要: 2015年3-4月,结合红螯螯虾(Cherax quadricarinatus Von Martens)育苗周期,对温室育苗系统水处理单元的水质指标实施周期监测。结果表明,水源水质的总氮(TN)、总磷(TP)、氨氮(NH3-N)、亚硝酸盐(NO2-N)、硝酸盐(NO3-N)和高锰酸盐指数(CODMn)均较低,符合养殖标准。在育苗期间,育苗池进水口的TN、TP、NO2-N和NO3-N的平均值最高,分别为6.2、0.76、0.035、4.2 mg/L;袋式过滤器的NH3-N浓度最高,平均为0.23 mg/L,各处理单元的CODMn值差异不大。随着育苗时间的延长,育苗水体各指标均有不同程度的升高。从处理单元分析,经处理后,水质指标明显改善,保证了育苗过程的顺利进行。

Abstract: During March to April in the year of 2015, we investigated and monitored the water quality changes of water treatment units in a closed recirculating nursery system for seed Cherax quadricarinatus Von Martens. The results showed that the values of TN, TP, NO2-N, NO3-N, NH3-N and CODMn were low in headwater and conform to the aqua-cultural standard. The highest average values of TN, TP, NO2-N and NO3-N appeared in nursery pond, the values were 6.2, 0.76, 0.035, 4.2 mg/L respectively. The highest average value of NH3-N was observed in the bagged filter(0.23 mg/L). There was no significant difference in CODMn in all water treatment units. The values of water quality indicators were increasing with breeding progress proceeding. The water quality was becoming better after water proceeding in various water treatment units and ensured the process of nursery breeding.

Key words: recirculating system, Cherax quadricarinatus Von Martens, nursery, water treatment
