Description

TECHNICAL FIELD

[0001] The utility model belongs to the surface water purification facilities of park lake or river. BACKGROUND

[0002] For the ecological management of semi-open water bodies such as park lakes or rivers, reducing external river water pollution is the key to maintaining the water quality of the internal water body. The commonly used external river interception structure includes oil containment boom, ecological screen, etc. The oil containment boom structure includes impermeable PVC cloth, foam float, stone cage ballast, and its principle is to float on the water surface by using foam float, block water by using PVC cloth, reduce water flow to maintain internal water quality. The ecological screen structure includes perforated HDPE net, foam float, stone cage ballast, and its principle is similar to that of the oil containment boom, but it has a certain water permeability. Compared with the structure of the utility model, the oil containment boom can only block water and cannot adsorb and degrade water pollutants, and the impermeable PVC cloth is easily broken by water flow during flood discharge, and the structure is unstable; the ecological screen can only filter large particles and cannot effectively reduce incoming water pollutants, and the structure is thin and only suitable for static water bodies. SUMMARY

[0003] The utility model provides a kind of semi-open water body water purification barrier structure, including fixed stake, barrier main body, top beautification device, wherein, the fixed stake is vertically driven into riverbed, and the barrier main body is tied on the fixed stake, wherein the barrier main body is that composite fiber mixed press layer is tied on square PVC pipe frame, and the top beautification device is installed on the top of the barrier main body.

[0004] Compared with the existing conventional technology, such as oil containment boom, ecological screen, etc., the water purification barrier main body is composed of composite fiber press layer, which can filter and adsorb and degrade the flow on one hand, and can avoid structural damage caused by excessive water flow resistance due to its water permeability. The water purification barrier has the pollution blocking effect of oil containment boom and the water permeability of ecological screen, and also has better filtering and biodegradation performance and better structural stability. It can play an important role in maintaining the water quality and transparency of park lakes, rivers and other ecological management water bodies.

[0005] Optionally, the specific surface area of the mixed press layer of plant fibers and polyester fibers is 2000 square / meter.

[0006] Optionally, the mixed press layer of plant fibers and polyester fibers is a 3D wire-like structure.

[0007] Optionally, the fixed stake is fixed at the junction of the management water body and the external polluted water body, and the barrier main body is tied to the fixed stake.

[0008] Optionally, the mixed press layer of plant fibers and polyester fibers has indigenous microorganisms aggregated therein.

[0009] In addition, the water purification barrier structure can greatly slow down the influence of the external pollution source on the water transparency and water quality indexes while maintaining the normal exchange of water flow. The water purification barrier first intercepts the polluted water flowing through, reduces the flow rate of the water flowing into the barrier, reduces the suspended impurities entering the barrier, and at the same time, the local microorganisms gathered in the purification barrier absorb and decompose the pollutants in the water, thereby reducing the pollutant concentration entering the internal water body.

[0014] In order to make the purpose and embodiments of the present application more clear, the exemplary embodiments of the present application will be described clearly and completely in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only some of the embodiments of the present application, not all the embodiments.

[0015] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0016] As Figures 1-3As shown, the device includes three parts of fixed pile 1, barrier body 2, and top beautifying device 3. The position and connection relationship between the parts are as follows: the fixed pile 1 is vertically punched into the riverbed, and the barrier body 2 is bound on the fixed pile 1, wherein the barrier body 2 is a composite fiber mixed pressure layer bound on a square PVC pipe frame, specifically including a single layer of 4cm thick plant fiber and polyester fiber mixed pressure layer 201 (total of 2 layers) and a 100 mesh HDPE net 202 (total of 3 layers), and the top beautifying device 3 is installed on the top of the barrier body 2. The beautifying device 3 can be only a horizontal rod 301 or be matched with a PVC pipe floating frame and floating plants 302. The fixed pile 1 functions to fix the entire water purification barrier, the barrier body 2 functions to slow down the flow rate and filter and adsorb and degrade the flow, and the top beautifying device 3 functions to beautify the top of the barrier and improve the ornamental value.

[0017] The device mainly relies on the barrier body 2 to achieve the water purification effect. The water purification principle is that the plant fiber and polyester fiber mixed pressure layer 201 has a specific surface area of 2000 square / meter, which can be used as a good biological carrier for the attachment and growth of microbial communities in rivers and lakes to form a microbial membrane and provide breeding space for planktonic animals to adsorb and degrade pollutants in water. At the same time, the HDPE net 202 filters the suspended solids in water. The use method is that the water purification barrier is fixed by the fixed pile 1 at the junction of the treated water body and the external polluted water body, the barrier body 2 is bound on the fixed pile 1, when the polluted water body flows through the water purification barrier, the barrier body 2 first intercepts the flow, can generate resistance to the water flow, reduces the flow rate of the water flow into the barrier, uses the HDPE net 202 to reduce the suspended impurities entering the internal water body, and uses the local microorganisms gathered in the plant fiber and polyester fiber mixed pressure layer 201 to adsorb and decompose the pollutants in water to reduce the pollutant concentration entering the internal water body.

[0018] Compared with the existing conventional technologies such as oil containment boom and ecological barrier net, the water purification barrier body is composed of a composite fiber pressure layer, which can have a good filtration and adsorption and degradation purification effect on the flow, and can avoid structural damage caused by excessive water flow resistance due to its water permeability. The water purification barrier has the pollution blocking effect of the oil containment boom and the water permeability of the ecological barrier net, and has better filtration and biodegradation performance and better structural stability. It can play an important role in maintaining the water quality and transparency of the ecological management water body of the park lake, river and the like.
