Abstract

Energy efficiency and economic viability are the often-quoted issues in aquaponic farming. This work aims to (i) identify process technologies and technical measures which would enhance the profitability of aquaponics business while conserving energy and other resources, and (ii) to validate the determined optimal measures on the testing aquaponics farm. The process network synthesis technique was used to search for an optimal process pathway while the image processing technique was applied to automatically monitor the growth rate of produce since it is the main revenue stream in aquaponics. With the aid of P-graph method, the optimal feasible structure has 9 times higher annual net income than that of the existing process. This optimal solution includes the integration of electrical heat pump, biogas system, and utilizes black solider fly (BSF) facility to produce fish feed. Additional light energy savings were achieved by practical installation of reflective foils which improved 16.88% of Photosynthetic photon flux density (PPFD) on growth beds. These measures can help the aquaponics farms to become more competitive and to decrease their ecological footprint.

基于过程监测和图形理论方法的鱼菜共生设施资源优化

在水培养殖中，能源效率和经济可行性是经常被提及的问题。这项工作旨在(i)确定在节约能源和其他资源的同时提高鱼菜共生业务盈利能力的工艺技术和技术措施，以及(ii)在测试鱼菜共生养殖场验证确定的最佳措施。利用过程网络综合技术寻找最优的过程路径，利用图像处理技术自动监测农产品生长速度，因为农产品是鱼菜共生的主要收入来源。借助于p图法，最优可行结构的年净收益比现有工艺高9倍。该优化方案包括电热泵、沼气系统的集成，并利用黑兵蝇(BSF)设施生产鱼饲料。通过实际安装反射箔，提高了生长床上16.88%的光合光子通量密度(PPFD)，实现了额外的光能节约。这些措施可以帮助水培养殖场提高竞争力，减少生态足迹。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
