生态浮床技术应用研究进展

近年来,随着工农业的发展,人类对水环境的破坏日益严重,全球出现水资源短缺的现象,如何有效利用水资源及将污废水处理回用已经成为摆在人们面前的头等大事.传统的物理、化学方法虽然理论基础比较扎实,但是在实际应用中出现了不少的问题,如投资大、难操作、产生二次污染等.为了解决这些问题,人们将目光转向了利用高等植物净化污水.生态浮床技术作为其中一种生物处理技术,已经被越来越多地用于治理富营养化水体.生态浮床以其独特的优点,通过植物根系的吸附和吸收作用,富集水中的N、P等元素,降解、富集其他有害无毒污染物,并以收获植物体的形式将其搬离水体,从而达到治理水体的目的,既保护了水生态环境,又带来了一定的经济效益.

Application of Ecological Floating Bed Technology

In recent years, with industrial and agricultural development, human has increasingly caused serious environmental damages on water, leading to the global shortage of water. Therefore, how to use water efficiently, how to treat and reuse sewage and waste water are placing in front of people, and have become a top priority. Although both traditional physics, chemistry have a solid theoretical foundation, there are a lot of practical applications, such as great investment, difficulty of operation, secondary pollution. In order to solve these problems, people turn attention to the use of higher plants in purification of sewage. Ecological floating bed technology as one of biological treatment technology has been used by more and more people to treat eutrophic water, as the bed is capable of absorbing N, P and other elements in water by plant roots, and degrading other harmful pollutants. As long as the plants are harvested so that these pollutants are moved out from the water body. It not only purifies the water and protects aquatic environment, but also brings a certain economic benefits.
