Abstract

Abstract: In order to study the rapid start⁃up of biofilters in seawater recirculating aquaculture systems, this study investigated the removal effects of seawater biological fluidized bed on pollutants under different hydraulic retention time (HRT) and temperature conditions, and explored the impact on initiation of seawater biological fluidized bed. The results show that: HRT=1 h experimental group can achieve material conversion and return to equilibrium more quickly, which is suitable for membrane loading; the high temperature conditions (28 ℃) are suitable for fluidized bed initiation, and the biofilm attachment growth can be observed more quickly.

Key words: Marine aquaculture wastewater, Biological fluidized bed, Temperature, Hydraulic retention time, Nitrification

摘要： 为研究海水循环水养殖系统生物滤器的快速启动，考察了不同水力停留时间（HRT）和温度条件下，海水生物流化床（BFB）对污染物的去除效果，探讨其对海水生物流化床启动的影响。结果表明，当HRT=1 h时，实验组能较快地实现物质间转化且更快恢复平衡状态，适合挂膜；高温条件（28 ℃）适合流化床启动，可更快观测到生物膜附着生长。
