V. Description of the invention (1) The present invention relates to a method for regulating multi-tributary rivers, especially a method for regulating rivers with seawater tides and using controlled water storage areas and dams. Those who return to the main channel. According to Taiwan, the terrain of Taiwan is narrow from east to west and long from north to south, and rivers mostly flow from east to west. Therefore, rivers have the characteristics of short flow and large gaps. The upper reaches of rivers have strong erosive forces because of high terrain and fast currents, often entraining large quantities. The sediment flows down the river, and when it reaches the downstream, the flat water flows slowly and causes a large amount of sediment to cause the river bed to rise and reduce the total water capacity of the river, and due to the mountains and the land, the over-exploitation of the soil and water is not good. A large amount of mud ::: brush the lower reaches of the Sichuan River, which makes the sediment deposition more serious, so the river valley is flooded with heavy rains and caused floods; furthermore, the river can be drawn by the water flow velocity. Ding Fa survives, 1 and Therefore, the low oxygen content of river water makes biology and microorganisms unreachable, and the population g can lose its self-cleaning function. In addition, Taiwan's industrial and commercial industries have developed, and most of the river wastewater and people's livelihood wastewater are directly discharged into the river to the river. Sewage discharged from the ocean will return to the sea when the tide rises, and the awareness will rise again. If tired, it will make the river stink. Although the environment has been in the billions of pairs in recent years, the renovation project has been undergoing years. Go ahead, the money spent is more difficult. —Yes, but it ’s difficult to improve river water pollution and river siltation. Therefore, the present invention λ its sedimentation fish ^ In view of the general river regulation which has not been improved for many years, there are applications > wood problems, so we are devoted to studying the method of river regulation "The law" proposed the application of "Master of the Master and No. 8 1 1 2 9 3 8" River Pollution Control Water Rising Tide Backflow 2 ^ Can effectively prevent the sewage discharged by the river from the sea '1' and was granted a patent by the Bureau of Jun Willingness

Page 4 593848 V. Description of Invention (2). Although the above-mentioned "River Pollution Remediation Method" can effectively improve river pollution problems, this method is mainly designed for the main river channel, and its effectiveness is limited to rivers with tributaries, and this method cannot solve the problem of river sedimentation. In view of this, the present inventors have devoted themselves to developing a method for remediation of multiple tributary rivers, in order to effectively reduce the degree of pollution of rivers and their tributaries, and to solve problems such as sedimentation in river channels, and to increase river capacity and reduce flooding. In order to achieve the above-mentioned object, the method and technical means of the "remediation method for multi-tributary rivers" of the present invention; an indefinite number of water storage areas or dams are set in the interval between the main channel of the river and its tributaries, and every two or two water storage areas Or the dam can divide the river's main channel or its tributary into several sections of flushing area, and then use the dam or water storage area to store water, and use the stored water to sequentially flush downstream from the upstream of the tributary of the river. Before flushing, the silt at the bottom of the river is stirred with a strong water column so that the sludge can move with the strong current during flushing and will not be deposited on the bottom of the river. Then the tributaries of the ocean and the main river channel jointly release the sewage before the tide recedes to the bottom. , Sewage and mud will be washed out into the sea with a strong current to make the next seawater rise: Sewage and sludge will not return to the river during the tide. In order to make your reviewing committee better understand the technical means of the present invention and the effects that can be achieved, it is explained in detail with the drawings and the Tamsui River and its tributaries as the preferred embodiments: Please refer to the first figure and The second picture shows the main channel 1 of its river

593848 V. Description of the invention (3) It is possible to set an irregular water storage area 2 or dam 3 according to the actual pollution, the degree of sedimentation and the size of the river. In this embodiment, the sides of the main channel 1 are adjacent to the estuary 4 A water storage area 2 is set as an example to explain in detail; each water storage area 2 is provided with a water inlet 2 1 on a side adjacent to the sea outlet 4, and each water inlet 21 has a controllable opening and closing The water inlet 2 1 1 is provided on the side of the water storage area 2 opposite to the water inlet 2 1 and the outlets 2 2 1 which are controlled to open and close are provided at each water outlet 2 2. The application is to open the water inlet 2 1 1 when the seawater is high tide. Clean seawater can enter the water storage area 2 through the water inlet 21 and close the water inlet 2 1 1 before the seawater ebbs, so the water storage area 2 The internal water level is the same as the main river channel 1. When the seawater ebbs, the water level of the main river channel 1 decreases and the water level of the impoundment area 2 is still maintained at a high level. The seawater will return to the bottom tide (about an hour ago). The gate 2 2 1 of the water outlet 2 2 of the water storage area 2 is opened, so that the clean sea water passes through the water outlet 2 2 Out, the sewage from the main river channel 1 is discharged to the open sea with a strong current, and the water gate 2 2 1 can be closed when the water level of the water storage area 2 is discharged to the same level as the water from the main river channel 1, so the above steps are repeated. Can reduce river pollution. Please refer to the third and fourth figures. The tributary 11 of the main channel 1 of the river can be set according to the actual pollution, the degree of sediment deposition and the size of the river. The embodiment is described in detail by setting several dams 3 on each tributary 11 of the main river channel 1; it is mainly because each tributary 11 on the main river channel 1 is provided with an indefinite number of dams 3, and each dam 3 is provided There is a gate 3 1 that can be controlled to open and close, and every two adjacent dams 3 separate each tributary 11 into several washing zones 1

593848 V. Description of the invention (4) In practical application, the dam 3 closest to the upstream of each tributary 11 is used as the starting point of the flushing. First, the three doors 3 closest to the upstream must be closed to reserve. The upstream clean river water is used for flushing: At this time, the gate 3 1 of the other dams 3 is open, and before the flushing, the silt at the bottom of the tributary 1 1 can be stirred with a strong water column to make the silt. Driven by the current, it will be stored near the dam 3 closest to the upstream; after enough water sluices can close its dam 3 gate 3 __, and then hit the closed door 3 i of the upstream dam 3 to keep the river water stored in the embassy from the dam 3 gushing shape 2 strong water flow to flush the flushing area 1 1 1 formed by the two dams 3, so repeat the steps described above to flush the flushing area of each tributary 1 1! i up to the tributaries i ^ the main channel Η confluence, and then cooperate with the main channel 1 and the tidal sand of the seawater to release the sewage from the tributaries i i lost to the mud, α strong mud is discharged from the estuary 4 to the sea. Please refer to the fifth and sixth figures for the paper. Take the production of Tamsui River 5 and its tributary 11 as an example. # 中 鲜 水河 5 is the main river 1 1 and its tributaries 1 1, Dahanxi 51, Xindianxi 5 2 and Ji ^ 3; according to the degree of pollution and sediment accumulation of Danshui River 5, several water storage areas 2 are set up on both sides of the Danshui River [watershed, to store water during high tide Water in order to dilute "5 tributaries of Dahan Creek 51, Xindian Creek" and more: Long River 5 3, also set up several dams according to the situation of each pollution and sedimentation ^, 甘 甘 ^^ 俏 狂 反 Ｍ And the beijing currents are divided into several stages of flushing = the two dams of the dam 3 are branched, and when the river is to be flushed, each branch 11 must be closest to the upstream

V. Description of the invention (5) Upper H: The door 31 is closed to store river water for flushing. After sufficient water has been stored on each branch, it can be washed in sections according to the method described above. The flushing area 1 1 1 up to the confluence of each tributary 11 and Tamsui River 5 · 1 and the sewage and silt at the confluence of each tributary 1 1 must be matched with the seawater tide / evening and the distance from the estuary 4, which is about one minute before the lowest tide Hours are released from the tributary 11 that is the furthest away from outlet 4 and this example is Dahanxi 5 1 which is the closest to estuary 4 in this embodiment, followed by Xindian Creek 5 2 and Keelung River 5 3 ' Dahan Creek 51 was released first. When the sewage sludge flows through the confluence of Xindian Creek 5 2 and Danshui River 5, the dam 3 of Xindian Creek 5 2 can open the gate 3 1 and flow through the Keelung River. When the confluence of 5 3 and Danshui River 5 is reached, the dam 3 of Keelung River 5 3 can open the gate 3 and merge with it to produce a strong water flow. The sewage from each tributary 1 and the mud in the river pass through the river 5 In the water zone 2 ', each animal water zone 2 can release its pre-stored water to make the water flow more powerful, and it can separate sewage and entrained sediment from Haikou 4 discharges to the open sea without returning the discharged sewage and freshwater to the freshwater river 5 when the mud is rising in the sea due to the slow flow of water. Therefore, repeatedly implementing the above method can gradually restore the freshwater river 5 and its tributaries 1 1 to the original clean. The appearance of the river and the increase of river capacity reduce the threat of floods to people's lives and property. It is worth mentioning that the dams of the tributaries 1 χ of the freshwater river 5 are capable of simultaneously storing an appropriate amount of river water and cooperating with the tide of the seawater. At the same time about one hour before the ebb tide, the river water to be stored by the tributaries is released at the same time. A stronger current can be generated to flush the freshwater river5, and the flushed sewage and sludge will be discharged to a farther sea, without returning to the freshwater river when the seawater rises.
