2种水葫芦-微生物系统水质净化效果的比较
Comparison of the Water Purification Effect of Two Kinds of Water Hyacinth-on Microbial System
摘要
Abstract
[ Objective ] This paper aims to study the effect of Wuxi water hyacinth and Yunnan water hyacinth with purple root on water purification. [ Method] The number and distribution of water hyacinth' s rhizospher microorganism are analyzed by using 10 types of cultural media.Biological traits of the water hyacinth and the water quality indicators are monitored. The water purification effect of Yunnan water hyacinth with purple root and Wuxi water hyacinth are compared and analyzed. [ Result] The microorganism, zooplankton and so on lived in the water have degradation effects on COD, NH3-N and TP. The plantation of water hyacinth could promote the degradation of TN, COD and TP. Wuxi water hyacinth has better ability on degradation TN than Yunnan purple root water hyacinth. Yunnan purple root of water hyacinth has better ability on degradation COD and TP. The Wuxi water hyacinth' s biomass is significantly larger than that of water hyacinth with purple root. The increased biomass of Wuxi water hyacinth is on the petiole while the increased biomass is on the rhizospher. Rhizospher actinomycete' s number of colonies of water hyacinth' s old roots haven' t significant difference, the new roots have significant difference. [ Conclusion ] The water purification effect of water hyacinth with purple root is stronger than that of Wuxi local water hyacinth, which provides theoretical basis for the rehabilitation of water nutrition enrichment of water hyacinth.关键词
