摘要:

以示范性循环水养殖厂产生的废水为监测分析对象, 采用在线连续监测和水样采集分析相结合的方法, 观测了该养殖厂废水的化学特征, 分析了影响水质的关键污染因子并探讨了其主要来源, 同时对当前循环水养殖技术进一步发展亟需改进的关键技术环节进行了分析。结果表明, 养殖废水中污染物的浓度与所养殖鱼的生长阶段相关; 废水化学耗氧量变化受到其中悬浮物的影响, 但化学耗氧量主要来源是水体中的溶解态物质; 废水中的氮、磷污染物主要以溶解态存在, 特别是无机形态。

Abstract:

In present study, we monitored the wastewater produced by a demonstrative recirculating aquaculture factory co-using on-line monitoring and grab sampling at multiple drainage ditches, investigated the major sources of the characteristic pollutants by data analysis, and brought our opinions forward for the further development of recirculating aquaculture. We found that the concentrations of pollutants were correlated with the growth phases of fish cultured in the corresponding tanks. COD was dominated by the dissolved matters, even though the variant amount of suspended solid resulted in the deviation of chemical oxygen demand (COD) of wastewater from the different tanks. Most of nitrogen or phosphorus compounds occurred in dissolved states, especially the inorganic forms.
