Description
Technical field
The present invention relates to a plant growth carrier, be specifically related to a kind ofly be applied to biological floating bed Inorganic material carrier.
Background technology
In the last thirty years, along with socioeconomic fast development, a large amount of undressed industry and sanitary sewage are directly entered river, lake, cause the loads of nutrition in its water body water system sharply to increase, and eutrophication is abnormal serious.And the improvement in polluted river, lake is a very thorny and arm and a leg difficult problem in water pollution control, biological floating bed purification techniques based on higher plant has that efficiency is high, cost is low, easy care, landscape effect are good, can realize the feature such as in-situ immobilization and control polluted articles, and can the various depth of water be adapted to, also comparatively artificial wet land system is easy for the management of plant and results, is therefore applied to more and more and administers or repair eutrophication water.
At present, artificial floating rafts construction is in various forms, but the research of floating bed carrier application mainly contains three major types: the first kind is plant roots and stems carrier, this carrier just utilizes pleuston the earliest, after develop into gradually and directly in eutrophication water, plant emergent and submerged plant, achieve many achievements in research.But due to the easy excessive multiplication of waterplant and aging death, not easily, thus this technology fails to directly apply in the improvement of fairly large eutrophic lake for results and process, Equations of The Second Kind is organic polymer carrier (as polystyrene foam and material modified etc.), because the manufacture craft of organic polymer material is very ripe, cheap, install, transport and remodeling are conveniently, thus floating bed makes in material and occupies an leading position at home, but there is critical defect in this kind of material in application, floating bed resistance to corrosion is poor, easily aging, can not life-time service, inconvenient maintenance, more seriously these materials are easily lost under stress, break, run off and not easily to salvage in water, cause secondary environmental pollution and potential safety hazard on the contrary, become one of principal element of its spread of restriction, 3rd class is inorganic carrier, inorganic materials has obvious advantage compared with organic polymer material in environmental benefit and raw material sources, thus Inorganic material carrier will become the main trend of floating bed carrier development undoubtedly, but current in the majority with laboratory study, there is no can the actual achievement in research dropping into application.
Summary of the invention
The technical problem to be solved in the present invention is to provide and is a kind ofly applied to biological floating bed Inorganic material carrier, this carrier is environment friendly and pollution-free, there is stable physico-chemical property, higher physical strength and stronger microorganism affinity, and be beneficial to microorganism growth, breeding, improve microorganism colonization efficiency, and work-ing life is longer.
