Research progress on the enhanced and combined method biofloc technology
摘要
Abstract
Biofloc technology(BFT)is a promising technology for the sustainable improvement of aquaculture productivity.In BFT,maintaining an appropriate C∶N ratio(10∶1-20∶1)by adding a carbon source promotes the growth of heterotrophic bacteria in water,heterotrophic bacterial assimilation of ammonia-nitrogen to bacterial biomass.In practical use,however,BFT system wastewater treatment functions remain limited in aquaculture.Besides,adding organic carbon also produces large amounts of suspended particulate that affects the health of aquatic animal.Therefore,it is necessary to optimize the BFT system wastewater treatment capability by using a variety of technical methods.Here,we introduce the principle of BFT and the problems in its application.The enhanced and combined methods of BFT,principles,application scopes and effects are discussed.We also highlight the effects of enhanced methods on the BFT system,including pollutants removal efficiency,microbial communities,and the growth performance of aquatic animals.The main messages from the result can be summarized as follows.Firstly,the cultivation of nitrifying bioflocs alleviates the need for organic carbon and dissolved oxygen in aquaculture systems,and reduces suspended solids.Besides,BFT reactor can cultivate high concentrations of bioflocs and improve the removal efficiency of nitrogenous compounds.Adding probiotics,microalgae,and substrates to BFT system improves the growth performance and immunity of aquatic animal,as well as enhance the microbial life and decomposition process,increasing the removal efficiency of nitrogen,phosphorus and organic matter.The coupled Integrated Multi-Trophic Aquaculture System,Recirculating Aquaculture System,and Aquaponics System with BFT can not only improve the nutrient use efficiency and production of aquatic animal,but also reduce the operating costs of the system.We also foresee the application of BFT would bring a change in the aquaculture mode in China.The in-depth research and application for an enhanced and combined method of BFT would further promote the sustainable development of the aquaculture industry.关键词
