摘要: In recent years, aquaculture plays an important role in life and has great economic value. With the rapid development of aquaculture industry and the increase of fish stocking, a large amount of feed and fish excreta need to be put into aquaculture, which leads to the problem of endogenous pollution in aquaculture environment, which leads to frequent occurrence of fish diseases and huge losses to aquaculture industry. In order to solve this problem, based on the advantages of constructed wetlands, such as good water purification ability and strong nitrogen and phosphorus removal ability, this paper studies a circulating aquaculture system based on constructed wetlands, which can improve the aquaculture quality and promote the healthy development of aquaculture industry. Firstly, this paper introduces the related knowledge and application of constructed wetlands; secondly, different types of wetlands are combined into a composite wetland to achieve better water purification effect; finally, the water purification effect, nitrogen and phosphorus removal effect and comprehensive benefits are analyzed. Experiments show that the proposed circulating aquaculture system based on constructed wetlands can effectively purify aquaculture water and remove nitrogen and phosphorus pollution, which has a good development prospect in aquaculture industry.
