Abstract: With the rapid development of aquaculture industry, recirculating aquaculture system has become a research hotspot of intensive aquaculture at home and abroad. In recent years, the problem of suspended particulate matter caused by intensive farming has attracted the attention of environmental protection departments and related aquaculture enterprises. The suspended particulate matter removal equipment can effectively remove solid suspended particulate matter in circulating aquaculture system, and is the core equipment of recirculating aquaculture system. This paper introduces the research progress of particulate matter removal equipment at home and abroad from the aspects of sedimentation separation, cyclone separation, foam separation, ozone oxidation, hole filter and biological aspects, and also compares the advantages and disadvantages of various particulate matter removal equipment technologies, so as to provide reference for the development and application of suspended particulate removal equipment in recirculating aquaculture system.

Key words: recirculating aquaculture system, suspended particulate, water treatment, filtering technique

摘要： 随着水产养殖业的快速发展，循环水养殖系统已成为国内外养殖集约化的研究热点，近年来养殖集约化带来的悬浮颗粒物问题引起了环保部门以及相关养殖企业的重视。悬浮颗粒物去除装备能够高效去除循环水养殖系统中的固体悬浮颗粒物，是循环水养殖系统的核心装备。从沉降、旋流、泡沫分离、臭氧氧化、孔过滤和生物过滤方面，介绍悬浮颗粒物去除装备的国内外研究进展，对比各式悬浮颗粒物去除装备技术的优缺点，旨在为循环水养殖系统中悬浮颗粒物去除装备研发和应用提供参考。
