一种利用象草净化水质的方法及使用这种方法的生态浮床

Abstract

The invention provides a method for purifying water quality by using pennisetum purpureum and an ecological floating bed applying the method. The pennisetum purpureum is planted on the ecological floating bed, and is used for absorbing, adsorbing, retaining and degrading contaminant through growth, so as to realize the purification of water quality. The method specifically comprises the steps of winding the stem base of a pennisetum purpureum cutting with a sponge bar absorbing enough water, fixing in a flower pot, placing the flower pot with plants in planting holes distributed along the water level of an water edge through a pot transferring device, when the pennisetum purpureum grows to 1 to 1.3m in height, reserving stubble with the length of 5 to 6cm and cradling. The ecological floating bed designed for the method consists of PVC (polyvinyl chloride) pipes and PS extruded sheets, and has the advantages of being wind and wave-resistant, antioxidant, extrusion resistant, long in service life, low-cost and the like. According to the method provided by the invention, the characteristics of large biomass, quick growth, developed root systems, cradle resistance and the like, and feeding and electricity generation functions of the pennisetum purpureum are utilized, and by applying the pennisetum purpureum into an ecological floating bed system, not only can water quality be effectively purified, but also economic output can be realized, so that the method is worthy of large-scale promotion.
本发明提供一种利用象草净化水质的方法及使用这种方法的生态浮床,将象草种植于生态浮床上,通过其生长对污染物的吸收、吸附、截留及降解,实现水体水质的净化。具体方法为:使用吸足水的海绵条绕缠象草插条茎基处并固定于花盆中,通过移盆工具将带植物的花盆置于沿水岸水面布设的生态浮床的栽植孔中,待象草长至1~1.3m时进行留茬5~6cm刈割。为本方法设计的生态浮床由PVC管和PS挤塑板构成,具有抗风浪、抗氧化、耐挤压、使用寿命长、成本低廉等优点。本发明利用象草生物量大、生长快、根系发达、耐刈割等特点,以及饲用与发电功能,将其应用于生态浮床系统中,不但可高效净化水质,而且可兼顾经济产出,值得大规模推广。
