Description

Technical Field

[0001] The invention relates to the field of river water treatment, and in particular to a water treatment system that is convenient for flood discharge. Background Art

[0002] At present, the drainage outlets of road drainage systems, various domestic sewage systems and industrial sewage systems are all introduced into the surrounding rivers, resulting in the discharge of muddy water, various domestic sewage and industrial sewage into the river in large quantities, causing serious river pollution. Over time, the sediments in the river continue to accumulate at the bottom of the river, increasing the difficulty and intensity of later cleaning. Cleaning is time-consuming and laborious, and requires frequent cleaning, consuming a lot of manpower and financial resources. At the same time, the large-scale discharge of various sewage has seriously polluted the water quality, making the river water black and smelly, and the water ecology has been severely damaged, losing its use value. Improving the water quality of the river is imminent.

[0003] Aquatic plants play a very important role in the purification function of water bodies. During their growth, aquatic plants absorb nutrients in the water, including nitrogen and phosphorus. By harvesting, the absorbed nitrogen and phosphorus are taken out of the water system. However, aquatic plants generally grow in water and close to the water surface, and the sewage treatment effect at the bottom of the river is not good. Therefore, it is necessary to add corresponding purification devices at the bottom of the river to treat the sewage at the bottom of the river. If corresponding purification devices are added at the bottom of the river, it will intercept the river water, resulting in poor drainage. During the rainy season and flood peak period, it will block the smooth drainage of water and cause the water level to rise, flooding the roads and fertile fields around the river, etc., posing a major safety hazard. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a water treatment system that is convenient for flood discharge and can effectively treat river water of any depth with good treatment effect.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] A water treatment system that facilitates flood discharge includes an ecological water purification device laid in a river channel, wherein the ecological water purification device is a microbial interception and attachment device vertically installed below the water surface, and the depth or thickness of the microbial interception and attachment device below the water surface can be adjusted to reduce the water blocking surface of the microbial interception and attachment device, thereby facilitating flood discharge.

[0007] The aforementioned microorganism interception and attachment device comprises a hanging layer and a microorganism interception and attachment layer. The upper end of the microorganism interception and attachment layer is connected to the hanging layer. The depth of the microorganism interception and attachment layer below the water surface is adjusted by lifting the hanging layer.

[0008] The aforementioned microorganism interception and attachment device includes a suspension layer, a microorganism interception and attachment layer and a bottom traction layer. The upper end of the microorganism interception and attachment layer is connected to the suspension layer, and the bottom traction layer is connected below the microorganism interception and attachment layer. The thickness of the microorganism interception and attachment layer below the water surface is adjusted by traction of the bottom traction layer.

[0009] The aforementioned hanging layer is a flexible net or a rigid grid or an ecological floating bed, and aquatic plants are arranged on the ecological floating bed.

[0010] A lifting anti-lodging net which is adjusted according to the growth height of the plants is arranged above the aforementioned ecological floating bed.

[0011] The aforementioned ecological floating bed is a fixed net or floating plate on which aquatic plant attachments are laid.

[0012] An aeration pipe is arranged at the bottom of the microorganism interception and attachment device, and the aeration pipe is connected with the air supply device on the river channel through an air transmission pipeline.

[0013] The aforementioned hanging layer is suspended on the water surface through a floating body, and the floating body is connected to a fixed object by a rope; or the hanging layer is connected and fixed to the fixed object by a rope.

[0014] The aforementioned bottom traction layer is connected to the traction rope or the lifting rod of the lifting mechanism. The bottom traction layer is lifted and lowered by dragging the traction rope or extending and retracting the lifting rod. The upper end of the traction rope is connected to the take-up device. The take-up device or lifting mechanism is located on a floating body, a hanging layer or a fixed object.

[0015] The aforementioned fixed object is a river bank or a vertical pile inserted into the river bed, and the suspension layer is composed of hollow tubes spliced ​​together; the suspension layer with buoyancy can be formed by sealing the ends of the hollow tubes.

[0016] Compared with the prior art, the present invention discloses a water treatment system that is convenient for flood discharge, which includes an ecological water purification device laid in the river channel. The ecological water purification device is a microbial interception and attachment device vertically arranged under the water surface. The depth or thickness of the microbial interception and attachment device under the water surface can be adjusted: during water treatment, the height of the microbial interception and attachment device is adjusted, and the microbial interception and attachment layer is completely under the water surface or unfolded, and the microorganisms in the river channel are vertically intercepted, providing favorable conditions for the attachment and growth of microorganisms. Then, the river water at the middle depth is treated with nitrogen, phosphorus, organic matter and suspended matter by microorganisms, which can effectively treat the deep water in the river channel; and during flood discharge, the microbial interception and attachment layer is lifted or completely condensed, which can reduce the water blocking surface of the microbial interception and attachment layer, which is convenient for flood discharge. Aquatic plants can be planted on the microbial interception and attachment device to remove nitrogen and phosphorus from the river water near the water surface, which is green and environmentally friendly; in addition, the microorganisms that have been attached and grown on the microbial interception and attachment device for a long time affect the beauty of the river channel, and the aquatic plants above the microbial interception and attachment device can be shielded to ensure the beauty of the river channel.

[0017] An aeration pipe is also provided below the microbial interception and attachment device. The gas released through the aeration pipe enables the activated sludge to effectively carry out aerobic respiration to separate organic matter into inorganic matter.

[0044] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0045] like Figure 1-Figure 3 As shown, a water treatment system that is convenient for flood discharge includes an ecological water purification device laid in a river channel 1.

[0047] Or, see Figure 3 The microorganism interception and attachment device 2 includes a hanging layer 201, a microorganism interception and attachment layer 202 and a bottom traction layer 203. The upper end of the microorganism interception and attachment layer 202 is connected to the hanging layer 201, and the bottom traction layer 203 is connected below the microorganism interception and attachment layer. The thickness of the microorganism interception and attachment layer 202 under the water surface is adjusted by traction of the bottom traction layer 203.

[0048] See Figure 4 The hanging layer 201 is a flexible net or a rigid grid or an ecological floating bed, and aquatic plants 3 are arranged on the ecological floating bed. The ecological floating bed can be a fixed net or a floating plate with aquatic plant attachment bodies. The aquatic plant attachment bodies are sponges, which are fixed on the fixed net or the floating plate. Or the aquatic plant attachment bodies include a permeable geotextile or a permeable geomembrane, which is filled with a filling matrix, and the permeable geotextile or the permeable geomembrane is arranged on the fixed net or the floating plate.

[0053] When it is necessary to adjust the depth of the microbial interception attachment layer 202 below the water surface, the rope tied to the fixed ring or the vertical pile can be untied, and the hanging layer 201 can be lifted up by the lifting device to adjust the depth of the microbial interception attachment layer 202 below the water surface to reduce the water blocking surface of the microbial interception attachment device and facilitate flood discharge.

[0054] See Figure 3-Figure 19 The bottom traction layer 203 is connected to the traction rope or the lifting rod 8.

[0063] See Figure 5 and Fig. 20The lifting anti-lodging net 11 includes a supporting layer 1101, on which a plurality of supporting grids 1102 are arranged for the three seedlings of aquatic plants to pass through. The four corners of the top of the supporting layer 1101 are connected to the fixed object through a pull rope or a lifting adjustment mechanism, and the bottom is connected to the hanging layer 201 through a telescopic rod 1103. In order to facilitate adjustment, the two ends of the telescopic rod 1103 are respectively hinged to the supporting layer 1101 and the hanging layer 201.

[0064] During the continuous growth of the aquatic plants 3, the length of the pull rope can be adjusted manually or by a winding mechanism, so that the support layer 1101 is raised as the aquatic plants 3 grow, preventing the aquatic plants 3 from falling over due to the influence of the water flow rate, which is more conducive to the growth of the aquatic plants 3.
