摘要

在循环水养殖系统中培养水生生物的现代技术需要大量的生物过滤器(约占鱼类养殖系统总体积的10%),这就需要寻找比传统聚合物填料具有更大的微生物定植比表面积的新填料,这将减少生物过滤器的尺寸,相应地,水产养殖产品生产的水电费。该研究的目的是评估使用高多孔泡沫玻璃作为生物过滤器填料的有效性,与传统的浮动聚合物负载相比。为了实现这一目标,采用了对特定问题的系统方法和一般的科学研究方法:实验、建模、比较、分析、综合和概括。模拟实验是在乌克兰国立生命和环境科学大学水生生物资源和水产养殖中心的教育和科学实验室进行的。根据实验结果,发现测试材料具有明显高于聚合物负载的生物过滤器的生物清洁潜力。在生长鲟鱼的循环水系统中,氨的最大浓度在白天被一个生物过滤器氧化,其中有1 dm3的泡沫玻璃作为填料(32 mg/dm3)。对水系中水生生物养殖过程中的潜在生物负荷进行了计算,发现在种植密度为41.6 kg/m3或84.8 kg/m3的商品鱼养殖材料时,10 md3的该填料能保持最佳的含氮水平。确定生物滤池所需体积减少4.55倍,循环水系统运行的供水和供能成本也将成比例降低。因此,使用泡沫玻璃作为循环水系统生物过滤器的填料将增加水产养殖企业鱼类生产的盈利能力

Efficiency of using foamed glass for biofilter of an aquaculture recycling system
Modern technologies of cultivation of hydrobionts in recirculating aquaculture systems require significant volumes of biological filters (about 10% of the total volume of the fish farming system), which makes it relevant to search for new fillers that would have a larger specific surface area for colonisation by microorganisms than conventional polymer filling, which would reduce the size of the biofilter and, accordingly, the cost of water and electricity for the production of aquaculture products. The purpose of the study was to evaluate the effectiveness of using highly porous foamed glass as a biofilter filler, compared to conventional floating polymer loading. To achieve this goal, a systematic approach to a particular problem and general scientific research methods were used: experiment, modelling, comparison, analysis, synthesis, and generalisation. The model experiment was conducted in the educational and scientific laboratory of the Centre for Aquatic Bioresources and Aquaculture of the National University of Life and Environmental Sciences of Ukraine. Based on the results of the experiment, it was found that the test material has a significantly higher bio-cleaning potential than polymer loading for biofilters. The maximum concentration of ammonia in the water of the recirculating aquasystem for growing sturgeon fish, which is oxidised by a biofilter with 1 dm3 of foamed glass as a filler (32 mg/dm3) during the day, was determined. Calculations of the potential biological load during the cultivation of hydrobionts in the aquasystem were carried out, and it was found that 10 md3 of this filler maintains an optimal level of nitrogen content when growing sterlet fish planting material with a planting density of 41.6 kg/m3 or 84.8 kg/m3 of commercial fish. It is determined that the required volume of the biofilter is reduced by 4.55 times, and the cost of water and energy supply for the operation of the recirculating aquasystem will also be proportionally reduced. Thus, the use of foamed glass as a filler for biofilters of recirculating aquasystems will increase the profitability of fish production at aquaculture enterprises
