Detailed ways

Fig. 1 has shown the basic structure of preferred embodiment of the present utility model, a kind of composite biological purification floating bed, comprises the three-dimensional frame that the upper layer can be suspended in the surface layer of water body, is located at the aquatic plant 1 of the upper layer of the three-dimensional frame, is located at the three-dimensional frame lower floor Biofilm Carrier Filler 2.

As shown in Figures 2, 3 and 4, the three-dimensional frame includes an upper frame 3 provided with at least one space unit, and a lower frame 4 arranged under the upper frame 3 and connected thereto. The upper frame 3 is made of glass fiber reinforced plastic hollow pipe with a rectangular cross-section. The hollow glass fiber reinforced plastic pipe is filled with polyurethane foam to make it a floating body. The upper frame 3 is further reinforced with reinforcements, which can highly resist and withstand the impact of large wind and waves Without being damaged, the reinforcements are plastic steel or aluminum alloy I-shaped or channel-shaped materials; the lower frame 4 is made of plastic pipes, such as pipes such as PVC, UPVC, ABS, etc. A plurality of equal-height plastic pipes arranged vertically, and connected with the ends of the vertical plastic pipes to form the plastic pipes arranged horizontally on the bottom surface of the three-dimensional frame, and the plastic pipes are connected to each other through elbows, three-way or four-way joints. In the present embodiment, the three-dimensional frame is a cuboid as a whole, and its upper frame 3 is made up of eight space units of 2.5m * 2.5m * 0.3m (thick). The specific height of the frame can be determined according to the depth of the water body to be treated.

As shown in Figure 2, in 8 space units of upper frame 3, honeycomb packing 5 is installed and filled in each space unit, and aquatic plant 1 is inserted in the honeycomb in honeycomb packing 5, and aquatic plant 1 can be selected as One of reeds, cattails, cattails, cannas, and narcissus. At the same time, aquatic plants can also be planted in a mixed variety. The aquatic plants adopt the water-borne method, and their flowers and leaves grow above the water surface, while their roots extend into the water layer below. middle. The biofilm carrier packing 2 is installed in the lower frame 4 , the biofilm carrier packing 2 is a braided curtain type soft filler 2 made of synthetic fiber fabric, and the braided curtain type soft filler 2 is fixed in the lower frame 4 . The braided curtain type soft packing 2 is arranged in parallel in multiple rows. According to the pollution degree of the water body to be treated, the layout spacing of each row of braided curtain type soft packing 2 is between 0.2 and 1m, and each row of braided curtain type soft packing 2 The spacing between the braids is between 3 and 10 cm.

The braided curtain-type soft packing 2 has a large surface area, and a large amount of biofilm can be attached and grown on its surface. The biofilm is composed of bacteria, fungi, algae, protozoa and metazoans, etc., and can efficiently remove pollutants in river or lake water. Various pollutants, such as organic matter (COD, BOD ₅ ), nitrogen, phosphorus, etc. The root system of the aquatic plant 1 on the three-dimensional frame is used as the living carrier of the biofilm, and the biofilm can also be attached and grown on its surface, which can degrade the pollutants in the river or lake water into inorganic products, such as CO ₂ , NH ₄ -N, NO ₂ ^- , NO ₃ ^- , Po ₄ ^3-, etc., they are absorbed by plant roots as nutrients and participate in the synthesis of new cells and the growth of new organisms, thereby promoting the metabolism of aquatic plants. Through the joint action of the purification of the root system of aquatic plants and the biofilm on the filler, pollutants in the water can be efficiently removed, and the ecological landscape of the treated river or lake is also improved (beautiful floating wetlands on the river bank and their good habitats) a variety of birds that are introduced from the land). The composite biological purification floating bed is a composite purification system composed of the root system of aquatic plants 1 and the biofilm on the braided soft filler 2. Compared with a single aquatic plant purification floating bed or biofilm purification hanging floating bed, it can more effectively decontaminate and purify river water or lake water.

When the composite biological purification floating bed is placed in the treated water body, the three-dimensional frame cooperates with a fixing device to fix the composite biological purification floating bed in the water body. One side adds iron anchor 7 to fix with stainless steel wire rope.

In this embodiment, according to the size and shape of the treated river or lake, the reservoir, multiple single compound purification floating beds can be connected and fixed together as required to form a larger floating bed, for example, 8 such The single floating bed is connected in a horizontal 4 vertical 2 way to form a conjoined floating bed with a width of 10m and a length of 40m; it can also be connected by more floating bed monomers to form a larger conjoined floating bed, such as a width of 20m and a length of 100m. Its periphery and middle are reinforced with I-shaped or channel-shaped stainless steel or carbon steel coated with anti-corrosion layer. These conjoined large-scale composite purification floating beds can be arranged along one side or both sides of the river, with a certain distance between them, such as 10m, where aeration units are installed to aerate the treated river or lake water Oxygenation to provide sufficient dissolved oxygen for the biofilm on the filler and the root system of aquatic plants to perform aerobic biological purification and maintain a good water ecological environment.

In order to improve the purification effect of polluted river water or lake water, special-effect bacteria can be added to the compound biological purification floating bed, such as iron flute bacteria, nitrifying bacteria, and anti-digestive bacteria that can effectively degrade those organic compounds that are difficult to biodegrade. denitrifying bacteria and aerobic denitrifying bacteria), phosphorus accumulating bacteria and sludge digestion bacteria, etc. They can attach and grow on biofilms and aquatic plant roots, and continue to grow and reproduce. They can purify river water or lake water more effectively than compound biological purification floating beds that do not add special-effect bacteria.

Through aeration and oxygenation, stirring and mixing, and adding special bacteria, the compound biological purification floating bed can remove pollution more efficiently, better improve the water quality of river or lake water, and better improve its ecological environment, and can also effectively restore Or improve the use value of its water resources. At the same time, by stocking snails, fish, etc. in the compound biological purification floating bed, a longer food chain can be established, the output of excess sludge can be effectively reduced, and the balance of sediment in the purified river section or lake area can be maintained for a long time.

Of course, the above-described embodiments are only the most typical embodiments of the present utility model, and do not limit the scope of protection of the present utility model, so all equivalent changes made according to the shape, structure and principle of the present utility model are acceptable.
