Problems solved by technology

[0003] However, in the above-mentioned method, the covering of the floating bed carrier blocks the water-air exchange between the surface of the water body and the atmosphere, which is not conducive to the natural reoxygenation of the water body. The carrier material itself is obtained by chemical synthesis, which belongs to non-environmental protection products, and The cost is also high, because the root system of the plant destroys the floating bed carrier, the floating bed carrier cannot be reused many times, it is inconvenient to carry out the seasonal connection of plants, and the waste is serious

Embodiment Construction

[0011] As shown in Figures 1 and 2, the floating bed 1 is made of natural materials such as wood, and a plurality of wooden strips 2 are arranged in the middle of the floating bed 1, and a plant area 3 is set on the wooden strips 2, and plants 6 are planted thereon; At the same time, set the filler hanging place 4, and hang the filler 7 here. The filler 7 is made of polyolefin and polyamide composites, and the materials selected are corrosion-resistant, temperature-resistant, and aging-resistant. Oxygen and other additives are radially distributed, and its structure is bionic, which is a three-dimensional elastic biofilm filler, which will not cause harm to aquatic animals such as fish; the multiple wooden strips 2 are hollowed out to form water-air exchange Zone 5: put a lot of floating beds 1 into the polluted water body to be treated, form a row and arrange them regularly, and the bionic filler 7 is arranged in a triangular shape at the bottom of the floating bed, and is reg...

Abstract

The present invention is method of in-situ purifying pollutant river water with combined floating bed plant and biomembrane technology. The float bed has float bed plant in the upper part, stuffing of polyolefin and polyamide suspended in water, and hollowed water-air exchange area in the middle part favorable to natural oxygen restoring of water. The bionic stuffing can intercept great amount of suspended matter in water and has biomembrane to eliminate organic matter, nitride and phosphate from water. The optimal float bed plant can remove nutritious pollutant from water. The present invention can stereo purify pollutant water and the float bed of timber and other natural material has long service life and facilitate plant replacement.

Description

technical field [0001] The invention relates to a treatment method or process for purifying polluted river water, in particular to a treatment method for in-situ purification of polluted river water using the biological-ecological technology of floating bed plant and biofilm composite technology. Background technique [0002] Before the present invention, there were many existing methods for purifying polluted river water, especially for waste water and eutrophic water bodies, artificially planting higher plants or improved terrestrial plants in eutrophic waters, through plant roots The mechanism of absorption, adsorption and competition between species can remove nitrogen, phosphorus and other pollutants and harmful substances in eutrophic water, so as to achieve the purpose of purifying water quality. For example, the use of floating bed technology to purify polluted water is a specific method, that is, the floating bed made of polystyrene foam board is used as a floating ...
