专利汇可以提供PROCESS FOR PURIFICATION OF WASTE WATERS AND CONTAMINANT SPILLS BASED ON THE USE OF CULTIVATED EMERGENT MACROPHYTES CONVERTED INTO FLOATING CULTURES专利检索,专利查询,专利分析的服务。并且The present invention relates to a system for the purification of residual waters and contaminant effluents based on the use of aquatic plants of the type of emergent macrophytes which have been conditioned in order to keep floating at the surface of channels, ducts, lagoons or ponds where contaminated water flows. The plants form a mantle floating on the water surface, while keeping immersed the root system, and the rhizones and the basis of the stems. The immersed portion has a large specific surface to which an abondant microbial flora is fixed and of which the growth is enhanced by the oxygen pumped towards that area by the leaves. The assembly formed by the roots and the micro-organisms acts as a filter which eliminates the organic dissolved material in addition to mineral compounds (phosphor and nitrogen, amongst others) which are absorbed mainly by the plants. Periodically, the floating biomass can be easily removed and used for energetic or industrial purposes.,下面是PROCESS FOR PURIFICATION OF WASTE WATERS AND CONTAMINANT SPILLS BASED ON THE USE OF CULTIVATED EMERGENT MACROPHYTES CONVERTED INTO FLOATING CULTURES专利的具体信息内容。
