生物浮床技术在水产养殖中的应用概况

Ecological floating bed technology and its application advancement in aquaculture

生物浮床技术作为生物操纵方法的一种,是一种原位生态修复技术,它是利用浮床植物根系或者茎叶吸收、富集、降解或固定受污染水体中的(有机)污染物,通过对植物的收割(收获)以实现降低或者消除水体污染物,达到净化水质、修复环境的目的。综述了生物浮床技术的原理与特点及生物浮床的应用效果,并结合生物浮床的技术特点探讨其在水产养殖应用中存在的问题,最后对生物浮床技术在水产养殖中的应用前景进行了展望。

Ecological floating bed technology （EFBT） was one kind of biomanipulations, and also a in-situ remediation technology. It uses the floating bed plant root or stem leaf to absorb, enrich, degrad or fix the （organic） pollutants in the contaminated water. Following the plants gaining, pollutants are reduced or eliminated, for the purification of water quality, environmental restoration. Study on the principle and characteristics, the application effect of EFBT were conducted, the application problems in aquaculture was discussed. At last, a feasibility analysis about its applied prospect in aquaculture was made.
