Problems solved by technology

At present, most of the fillers used in this type of ecological floating bed are soft fillers and elastic three-dimensional fillers. Since these fillers are developed for the application of sewage treatment plants, the geographical and hydrological characteristics of natural water bodies (such as rivers and lakes) are not considered. etc. In the application of natural water purification, there are difficulties in installation and replacement, large water flow resistance, easy to be damaged by water flow impact, and easy to knot, which greatly limits its practical application in the purification of polluted natural water.
Patent 200410099196.0 invented a kind of granular high-efficiency nitrogen and phosphorus adsorption materials such as granulated fly ash, zeolite, artificial zeolite, vermiculite and biological ceramsite under the floating bed for microbial film hanging, but such carriers have specific gravity Problems such as large and easy to block
On the other hand, although the use of the above-mentioned fillers has a good biological nitrification effect, due to the low concentration of organic matter in natural river and lake water, the supply of carbon sources for microbial denitrification is insufficient, which greatly limits its biological denitrification ability.

Abstract

The invention relates to a combined type ecological floating bed water purifying device used for in-situ purification treatment of polluted water in rivers and lakes. A floating body frame of a floating bed is provided with a grid-like bamboo charcoal floating bed main board made of bamboo charcoal pieces which are processed intensely by a compound enzyme biological promoter before being used, and when the bamboo charcoal pieces are used, the bamboo charcoal pieces can quite well adsorb nitrogen and phosphorus in the water and effectively promote the attached growth of indigenous microorganisms in the water; grid holes on the bamboo charcoal floating bed main board are used as planting holes of plants, and various aquatic plants or economic plants with water purification function can be mixedly planted; and biological fillers are arranged on the lower part of the floating bed, and biomass-based materials which are natural vegetable fibers are used by biofilm formation of microorganisms. The device can greatly improve the capability of removing nitrogen, phosphorus and organic matters from the eutrophication water of the ecological floating bed device and has the characteristics of simple structure, convenient mounting and control, high water flow impact resistance and the like, so that the device is quite suitable to be used for the in-situ purification treatment of water in natural rives, lakes and reservoirs and scenic water.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and specifically relates to a combined ecological floating bed water purification device for in-situ purification treatment of river and lake polluted water. Good landscaping effect. Background technique [0002] In recent years, with the rapid development of social economy, the discharge of water body pollutants has increased year by year. Natural water bodies such as rivers, lakes and reservoirs in my country have been polluted to varying degrees, and there is a tendency to intensify, which seriously threatens people's lives and health. Natural water bodies Pollution prevention and control has become a major problem that needs to be solved urgently. [0003] The existing river and lake polluted water treatment technologies mainly include physical and chemical methods and biological ecological methods. The physical and chemical methods mainly include diversion of water for water exchang...
