Abstract
Description
Technical Field
[0001] The invention relates to the field of river water purification, and in particular to an artificial wetland system suitable for river water purification. Background Art
[0002] The complete set of technologies for river artificial wetland restoration includes river channel in-situ artificial wetland restoration technology and river channel ex-situ artificial wetland restoration technology. The river channel in-situ artificial wetland restoration technology purifies water quality by directly building artificial wetlands on the river channel, so that the functional indicators of the river water body reach the expected range. This technology has the defects of changing the original state of the river channel and affecting the flood control function of the river channel. The river channel ex-situ artificial wetland restoration technology is based on the tributaries of the polluted river. According to the principles of regulation, retention, purification and natural river channel simulation, a drainage channel is built to form a bypass. The polluted river water is introduced from the tributaries into the bypass to increase the residence time of the polluted river water in the bypass. In the bypass, the combination of offline and online ecological engineering technology and environmental engineering technology is optimized to artificially strengthen the self-purification function of the river. The purified river water is then merged into the mainstream, gradually improving the river water quality and restoring the river ecology. This technology has many advantages such as not changing the original state of the mainstream river channel, not affecting the flood control of the mainstream, and good water quality purification and ecological restoration effects.
[0003] Generally speaking, river ex situ artificial wetlands and rivers are independent aquatic ecosystems. Using the riverbed to construct wetlands in situ can not only reduce the amount of engineering work, but also organically combine artificial wetlands and rivers. However, there are few technologies and methods for purifying river water using this technology. Therefore, using part of the riverbed to construct wetlands and purify the river water in the entire section is of great significance for the prevention and control of river pollution. Summary of the invention
[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a suitable river water purification system.
[0005] In order to solve the above technical problems, the present invention is a water purification system suitable for river channels, including a water storage area, an overflow dam, a water intake dam, a water intake system, an artificial wetland, a river bank, a downstream discharge area, and a waterfall step below the overflow dam. The river bank is divided into two sides, one of which is divided into a purification section river bank with a middle part protruding outward, an upstream river bank located upstream of the overflow dam, and a downstream river bank located downstream of the overflow dam. The water storage area is located upstream of the overflow dam, the overflow dam is connected to the water intake dam, and the overflow dam is lower than the water intake dam. The water intake dam is closely connected to the purification section river bank. The water intake dam and the purification section river bank enclose the upstream water intake area. A water transfer hole is set below the water intake dam, and the height of the water intake dam is higher than the highest flood level of its river section. The water intake system includes a water intake head, a buoy and a hose. The upper disc and the lower disc of the water intake head are connected by a vertical water baffle. The gap between the water baffles forms a water inlet section. There is an opening in the center of the lower disc. The lower disc is connected to one end of the hose. The other end of the hose is connected to the water delivery hole of the water intake dam. The buoy is fixed to the water baffle through a connecting rod. A positioning rod is arranged at the lower part of the buoy. The positioning rod is inserted into the hollow positioning cylinder. The positioning cylinder is fixed to the bottom of the river. The partition wall connected to one end of the water intake dam and located downstream of the water intake dam, the water intake dam and the purification section of the river embankment form an artificial wetland area. The upstream river embankment, the downstream river embankment and the partition wall are in the same straight line. The partition wall is higher than the highest flood level of the river section where it is located. The artificial wetland is set at least one level and is set lower in sequence. A water distribution channel is set at the front end of the artificial wetland. The water delivery hole is connected to the water distribution channel of the first level artificial wetland. The downstream discharge area is located downstream of the artificial wetland.
[0006] The bottom of the upstream river embankment and the bottom of the water intake dam are connected by a sand retaining dam, and the upper part of the upstream river embankment and the upper part of the water intake dam are connected by a slag retaining dam. The gap between the sand retaining dam and the slag retaining dam forms a water channel, and the height of the slag retaining dam is higher than the highest flood level of its river section.
[0007] A fixing rod is arranged on the upper part of the buoy, and a weight is sleeved on the fixing rod.
[0008] Compared with the prior art, the present invention has the following beneficial effects: (1) The purification system introduces water from the upstream of the river into the wetland through the water intake system of the water intake area, so that the river water can be effectively purified; (2) At normal water level and flood level, the weight of the heavy object can be adjusted to adjust the depth of the buoy sinking into the water, and the water baffle is driven by the connecting rod to adjust its sinking depth below the water surface, and then the area of the water inlet section is adjusted, thereby adjusting the amount of water entering the hose, so as to achieve the purpose of adjusting the amount of water entering the artificial wetland for treatment. At the same time, the rise and fall of the liquid level will not affect the treatment amount of the artificial wetland, thereby stabilizing its operating effect; (3) The purification system utilizes the horizontal natural space of the river and the terrain with a drop, integrating water purification, water storage and waterfall landscape functions.

The river bank 600 is divided into two sides, one of which is divided into a purification section river bank 601 with a middle part protruding outward, an upstream river bank 602 located upstream of the overflow dam, and a downstream river bank 603 located downstream of the overflow dam. The water storage area 100 is located upstream of the overflow dam 200. The overflow dam 200 is connected to the water intake dam 300, and the overflow dam 200 is lower than the water intake dam 300. The water intake dam 300 is closely connected to the purification section river bank 601. The water intake dam 300 and the purification section river bank 601 enclose the upstream water intake area 301. A water delivery hole 302 is arranged below the water intake dam 300. The height of the water intake dam 300 is higher than the highest flood level of its river section.
[0014] The water intake system 400 includes a water intake head 401, a buoy 402 and a hose 403. The upper disc 4011 and the lower disc 4012 of the water intake head 401 are connected by a vertical water baffle 4013. The gap between the water baffles 4013 forms a water inlet section 4014. The lower disc 4012 has an opening at the center. The lower disc 4012 is connected to one end of the hose 403. The other end of the hose 403 is connected to the water delivery hole 302 of the water intake dam 300. The buoy 402 is fixed to the water baffle 4013 by a connecting rod 4021. A positioning rod 4022 is arranged at the lower part of the buoy 402. The positioning rod 4022 is inserted into a hollow positioning tube 4023. The positioning tube 4023 is fixed to the bottom of the river channel.
[0015] The partition wall 501 connected to one end of the water intake dam 300 and located downstream of the water intake dam 300, the water intake dam 300 and part of the purification section river embankment 601 form an artificial wetland 500 area, the upstream river embankment 601, the downstream river embankment 603 and the partition wall 501 are in the same straight line, the partition wall 501 is higher than the highest flood level of the river section where it is located, the artificial wetland 500 is set at least one level, and the setting is lowered in sequence, a water distribution channel 502 is set at the front end of the artificial wetland 500, and the water transfer hole 302 is connected to the water distribution channel 502 of the first-level artificial wetland 500, and then enters the downstream discharge area 700 after being purified by the subsequent artificial wetlands 500.
[0016] The bottom of the upstream river bank 601 and the bottom of the water intake dam 300 are connected by a sand retaining dam 303, and the upper part of the upstream river bank 601 and the upper part of the water intake dam 300 are connected by a slag retaining dam 304. The gap between the sand retaining dam 303 and the slag retaining dam 304 forms a water channel 305.
[0017] A fixing rod 4024 is provided on the upper part of the buoy 402 , and a weight 4025 is sleeved on the fixing rod 4024 .
[0018] The following is a detailed description of the use of the present invention.
[0019] Regulation of water volume in artificial wetland 500: By increasing or decreasing the weight of adjustment weight 4025, the depth of sinking of float 402 under water is adjusted, and the depth of sinking under water surface is adjusted by driving water baffle 4013 through connecting rod 4021, and then adjusting the area of water inlet section 4014, thereby adjusting the amount of water entering hose 403, so as to achieve the purpose of regulating the amount of water treated entering artificial wetland 500.
[0020] When the water volume in the river is normal, the normal water volume is greater than the processing volume of the artificial wetland 500. After the weight 4025 is adjusted to a suitable weight, part of the river water enters the water intake area 301 through the water trough 305, and the sand retaining dam 303 can prevent the sediment at the bottom of the river from entering the water intake area 301, and enters the hose 403 through the water inlet section 4014, and then enters the artificial wetland 500. The processing volume of the artificial wetland 500 remains normal and stable, and the river liquid level rises above the top of the overflow dam 200. The excess water flows downward from the overflow dam 200 and achieves energy dissipation, aeration and waterfall landscape effects through the waterfall steps 800.
[0021] When the river is in the dry season, the water volume in the river is small, less than the normal processing capacity of the artificial wetland 500, the liquid level in the river drops until it is lower than the overflow dam 200, and the buoy 402 and the water intake head 401 also drop until the bottom of the buoy 402 supports the upper end of the positioning cylinder 4023, so that the liquid level in the river no longer drops, ensuring the minimum liquid level in the water storage area 100, and all river water must enter the artificial wetland 500 through the water intake head 401.
[0022] When the river is in flood discharge, the water volume in the river is greater than the processing volume of the artificial wetland 500. The water level in the river rises sharply, and the water level is lower than the water intake dam 300, the slag retaining dam 304 and the partition wall 501. The slag retaining dam 304 prevents the turbulent flood from disturbing the water intake area 301 and destroying the water intake system 400. A large amount of flood water is discharged from the overflow dam 200. The water intake head 401 will also rise in height under the action of the buoy 402, but the weight 4025 does not change, the depth of the buoy 402 sinking into the water surface does not change, the area of the water inlet section 4014 remains unchanged, and the amount of water entering the artificial wetland 500 remains unchanged, thereby avoiding a huge change in the load of the artificial wetland 500.
[0023] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
