In the filter chamber, a rectifying plate is provided in parallel with the inflow direction of the raw water above the supply pipe. Raw water is uniformly supplied into the filter chamber along this rectifying plate. While the filter medium layer formed by the floating fiber filter medium is raised, the solid component contained in the raw water is captured by the filter medium layer. The separated treated water flows into the water collecting chamber uniformly through a plurality of small holes in the entire surface of the water collecting plate opened in the upper part of the filtering tank. The place where the water is collected -9-(6) (6) 200410748 Water is discharged from the top of the filter tank to the outside. In this way, when the filtration operation is continued, if the filter material layer becomes clogged or the filtration speed is reduced, the filter material needs to be regenerated and washed. To clean and regenerate the filter medium, first stop the flow of raw water, open the drain valve, and drain the raw water in the filter. At this time, the treated water in the water collecting chamber is replaced with the raw water by the water collecting plate. When the treated water passes through the water collecting plate and the water level in the filter chamber reaches near the lower surface of the water collecting plate, the drain valve is closed to stop the discharge of raw water. Then, a stirrer provided in the filter tank is driven, and air is ejected from a diffuser pipe to generate a swirling flow in the filter chamber. The filter medium constituting the filter medium layer peels off the solid matter attached to the surface or the inside of the filter medium by repeatedly repeating the filter mediums or the conflict between the filter medium and the air bubbles while riding the swirling flow. Since the air diffuser is provided at a position that promotes the swirling flow generated by the agitator, it can be efficiently swiveled up to the upper part, and the solid can be peeled from the filter material in a short time. Furthermore, depending on the contaminated state of the filter medium, it is possible to regenerate the filter medium using only air from the air diffuser without using a stirrer. Then, the supply of the agitator and air was stopped, and the drain valve was opened to discharge the sewage in the filter chamber. When the discharge is completed, the drain valve is closed, the washing water is supplied from the raw water inlet, and the drain valve is opened. After a predetermined time has elapsed, the agitator is driven to eject air from the diffuser pipe to generate a swirling flow to clean the solids remaining in the filter medium. The washing drainage is discharged to the outside through the drainage valve. As described above, when the cleaning and regeneration of the filter medium is completed, the supply of the agitator and air is stopped. Then, the raw water is supplied again, and the washing and drainage remaining in the water collecting chamber are continuously replaced with the treated water. If the drain valve is closed at the time of replacement, the treated water valve is opened, and the filtering operation is started, then -10- (7) (7) 200410748 can take out the clear treated water.

The raw water flows in through the inflow port 19 of the raw water communication pipe 18 provided in the filter tank 1, and passes through the inflow valve 11 interposed in the raw water communication pipe 18. The raw water flows into the filter tank 1 from the bottom of the filter tank 1 through a plurality of supply pipes 20 connected to the raw water communication pipe 18. The raw liquid flowing into the filter tank 1 is guided by a rectifying plate 21 that is stretched near the upper portion of the opening of the supply pipe 20 and is uniformly supplied into the filter chamber 4. The fairing plate 21 is slightly larger than the width of the opening of the supply pipe 20. The rectifying plate 21 is stretched from the tank wall of the filter tank to the other tank wall in parallel with the inflow direction of the raw water. For the rectifying plate 21, a member having many small holes such as perforated metal is used.

The other end of the water collecting pipe 31 is connected to the treated water communication pipe 22. The treated water flowing into the water collecting chamber 3 is taken out through the treated water outlet port 2 3 through the treated water valve 1 3 interposed in the treated water communication pipe 2 2 to the outside. The treated water communication pipe 22 is branched in front of the treated water valve 13 and is connected to the L-shaped drainage pipe 24 with the drainage valve 14 interposed therebetween, and its terminal portion is used as the drainage port 25. Then, the drain pipe 24 is directly connected to the drain pipe 26 in which the drain valve 16 is inserted in front of the drain port 25. The other end of the drain pipe 26 is opened at the bottom of the filter tank 1. In the filter chamber 4, the air diffuser 8 and the mixer 9 are arranged in the lengthwise direction of the filter tank 1. The air diffusing pipe 8 extends from one side wall to the other side wall of the filtering tank 1 along the horizontal axis, and is arranged near the peripheral wall below the filtering chamber 4. The mixer 9 is disposed near the peripheral wall on the side opposite to the diffuser pipe 8 with respect to the vertical axis, that is, a position where it does not interfere with the lower surface of the filter material layer 7 when stirring. An air removal valve 27 is provided on the top of the treated water communication pipe 22 to release the air in the filter tank 1 to the atmosphere. The filter tank 1 is provided with a manhole 28 for inspection. An inspection window 2 9 is provided in the filter chamber 4. Next, the mixer is explained in detail based on FIGS. 4A to 4C. The shaft 10 of the drive machine 30 embedded in the mixer 9 is extended from one side wall of the filter tank 1 to the vicinity of the other side wall. At both ends of the shaft 10, stirring blades 1 1 a and 1 1 b inclined at a 45-degree angle with respect to the shaft center are provided. Both ends of the shaft 10 are supported by bearings 10a at positions adjacent to the stirring blades 1a and 1b. The bearing 10 A is supported by a support member 1 Ob fixedly attached to the wall of the filter tank 1. A plurality of agitating blades 1 1 c are arranged parallel to the shaft center between the bearings 10 a. Furthermore, in FIG. 4, the agitating blade -12- (9) (9) 200410748 1 1 a is inclined with respect to the axis of the axis 10 by 45 degrees downward. The stirring blade 1 1 b is inclined at an angle of 45 ° with respect to the axis. The stirring blades 1 1 a and π b cause a flow toward the center of the shaft 10, respectively. The bearings 10a and 10b are configured to collect the fiber filter materials 5 and 6 near the side wall at the central portion of the filter tank 1 when the mixer 9 is driven. The stirring blade 丨 丨 c is caused by the swirling flow around the shaft 10, so the action is to rotate the fiber filter materials 5 and 6 in the up and down direction, that is, to rotate around the horizontal axis of the filter tank 1. Next, the filtration process according to the present invention will be described with reference to the flowchart in Fig. 5A and the timing charts in Figs. 5B and 6. During the filtering process, the inflow valve 12 and the treated water valve 1 3 are opened. The raw water is transported by raw water Xupu (not shown) through the inflow valve 12 and flows into the filter chamber 4 of the filter tank 1. The raw water flowing into the filter chamber 4 rises from below the filter medium layer 7 and captures solids in the raw water between the passing filter medium layers 7. The raw water becomes clear water, is stored in the water collecting chamber 3 through the water collecting plate 2, and is taken out from the upper part of the water collecting chamber 3 through the treatment water valve 13 to the outside. If the filtering process is continued, the filter material layer 7 is clogged by the captured solids, causing the pressure in the filter tank 1 to rise, and the filtering speed to gradually decrease. In such a state, the filter medium layer 7 needs to be washed and regenerated. In order to detect clogging of the filter medium layer 7, a pressure switch or the like (not shown) detects the pressure in the filter tank 1. If the pressure switch detects that the pressure is equal to or higher than the set pressure, the filtering process is stopped and the filter material layer 7 is stirred and washed. Next, the process of stirring and cleaning the filter material layer 7 will be described. Stop the raw water pump (not shown), close the inflow valve 12 and the treated water valve 1 3, and end the filtration process. Next, a stirring preparation step is performed before the stirring step. First -13- (10) 200410748 First, open the drain valve 16 so that the treated water stored in the water collection chamber 3 is reversed to the filter chamber 4, and the drain valve 16 discharges the remaining product in the filter chamber 4. Then, when the liquid level in the filtering chamber 4 becomes lower than that of the water collecting plate 2, the shallow water valve 16 is closed. Then, the disturbance workers to the subtractive layer 7 are removed. First, the agitator 9 is driven, the air supply valve 15 is opened, and the diffuser pipe 8 supplies air. The amount of air used for diffusing air is, for example, 10 2 Nm3 / m2 · Hr. The mixer 9 is rotated in an arrow P direction as shown in FIG. 5. As a result, a swirling flow is generated in the lower part of the filter chamber 4 in the direction of the arrow Q. The swirling flow of the arrow Q rises by the air increasing speed supplied by the air diffusing pipe 8, and a swirling flow of the arrow R direction is formed on the upper part of the filter chamber 4. By the swirling flow of the arrow Q and the arrow R, the fiber filter materials 5 and 6 constituting the filter material layer ride the swirling flow, and while rotating up and down, the fiber filter materials 5 and 6 repeatedly conflict with each other, or the fiber filter materials 5 and 6 It collides with air bubbles from the air diffusing tube 8. Thereby, the solid matter adhering to the surface or the inside of the filter materials 5, 6 is peeled off. The air supplied from the air diffusing pipe 8 is released into the atmosphere by an air removing valve provided at the top of the treated water communication pipe 22. Then, the agitator 9 is stopped and the air supply valve is closed to complete the agitating process. Next, the fiber filters 5 and 6 are washed. The above-mentioned diffuser pipe 8 is shown in Figs. 5A and 5B, and a plurality of branches are set at a position of 15 to 75 degrees from the horizontal line HL to the center of the water axis 0 of the filter tank 1. 2). The air diffusing pipe 8 is suitable for use according to the pollution degree or operating condition of the fiber filters 5 and 6. It is suitable to use one or more. First, open the shallow water valve 1 6 to discharge the sewage from the filter chamber 4, and in the drainage water sequence, flow from the side to the back 7 Bian Baiwei's 2 7 15 Re-leveling the branch water 14- (11) (11) 200410748 After closing, close the drain valve 16. Then, the drain valve 14 and the washing water valve 17 are opened, and the washing water is supplied into the filter tank 1. When the filter tank 1 is substantially filled with water, the mixer 9 is driven to open the air supply valve 15 to supply air. The fine fiber particles 5 and 6 remaining in the fiber filter materials 5 and 6 are removed by washing the fiber filter materials 5 and 6 with a swirling flow while stirring. The washing and draining water is discharged from the water collecting chamber 3 through the drain valve 14 to the outside. After the washing and regeneration of the fiber filters 5 and 6 are completed, the agitator 9 is stopped, and the air supply valve 15 and the washing water valve 17 are closed. The inflow valve 12 is opened and a raw water pump (not shown) is supplied. The raw water is supplied into the filter chamber 4 and the washing and draining water remaining in the water collecting chamber 3 is replaced with the treated water (water-retaining process). Then, when the drain valve 14 is closed and the treated water valve 13 is opened, the water-retaining process is completed, and the fiber filters 5 and 6 are washed and regenerated. Then, the filtration process was resumed. In addition, when the turbidity of the solid matter in the washing and draining water is low, or when the specific gravity of the solid matter is small, the separated solid matter may adhere to the fiber filters 5 and 6 again. Therefore, there may be a case where the drainage step is not performed after the completion of the stirring, and the washing step is performed immediately thereafter. φ In addition, in the stirring step, the stirrer 9 may be stopped and the filter material layer 7 may be stirred by the air bubbles from the air diffusing pipe 8. In this case, the amount of air used for diffusion is 15 to 25 Nm3 / m2 · Hr. The relationship between the installation position of the air diffuser and the stirring effect will be described with reference to Fig. 5B. Here, the horizontal angle HL on the right of the figure on the horizontal axis 0 is used as a reference, and the periphery around the counterclockwise is taken as a positive angle. First, in the filter tank 1, the air diffuser is positioned in a range A of -15 ° to + 180 ° for the horizontal line HL. In this case, only the upper part of the air diffusing pipe 8 and the filter material -15- (12) (12) 200410748 around the mixer 9 flowed, and the entire filter material layer 7 did not flow. Secondly, the diffuser tube 8 is positioned in a range B from +1 8 0 ° to + 2 4 0 ° for the horizontal line H L. In this case, the upper part of the diffuser pipe 8 and the filter material around the mixer 9 flow, but the entire filter and material layer 7 does not flow. Thirdly, the diffuser 8 is positioned in the range C from + 240 ° to +2 8 5 ° for the horizontal line HL. In this case, the filter medium around the mixer 9 and the lower portion of the filter medium flows, but the filter medium near the water collection chamber 3 on the upper side of the filter layer 7 does not flow. Therefore, the entire filter material layer did not flow. Fourth, the air duct is positioned in the range D from +28 5 ° to +3 4 5 °, or -15 ° to -75 ° for the horizontal line HL. In this case, the filter medium layer 7 flows as a whole and rotates inside the filter tank. From the above results, it can be seen that it is good to arrange the diffuser in the range D. Figures 7 and 8 are perspective views of the floating fiber filters 5 and 6 used in the present invention. This fiber filter is a non-woven fiber filter made of three types of synthetic resin fibers with different fiber diameters. The first fiber yarn 5a is a heat-fusible composite fiber coated with a polyethylene core material and has a fineness of 18 to 65 denier. The material of the second fiber filament 5 b is polypropylene fiber, and its fineness is 3 to 10 denier. The third fiber filament 5c is a heat-fusible composite fiber coated with a polyethylene core material and has a fineness of 1.5 to 6 deniers. The web with 5 a, 5 b, and 5 c blended with the fibers was shaped by acupuncture. 'The fluffing state of the web on both sides was not smoothed and heated to form a plate-like body, and the board was cut. Shape. The fiber filter material 5 is a rectangular parallelepiped or cube having an appearance specific gravity of 0.7 to 92, a thickness of 2 to 30 mm, a width of 5 to 30 -16- (13) 200410748 ηι, and a length of 5 to 30 mm. Since the fiber filter material 5 is composed only of polypropylene fibers, its specific gravity is approximately 0.92. When the specific gravity is adjusted to 0.92 or less, as shown in FIG. 8, as in the fiber filter material 6, the foamable resin plate 6 a is sandwiched in the above-mentioned plate state, and then bonded and cut. For the foamable resin plate 6a, expanded polystyrene having a smaller specific gravity than that of the fiber filter material 6 is used. Thereby, the specific gravity can be arbitrarily adjusted from 0.7 to 0.92. The specific gravity of the foamable resin plate 6a can be made smaller, and the specific gravity of the fiber filter material 6 can be made 0.7 or less. As described above, the most suitable fiber filter materials 5 and 6 can be selected in accordance with the raw water state or the direction of filtration operation.
第9圖是本發明的第2實施形態之過濾裝置。用來處 理含有石頭或布等的夾雜物或污泥殘渣之生水。在此情況 時，若這些夾雜物或污泥殘渣混入至過濾槽1內的話，則 會有形成濾材層7早期堵塞的原因，或損傷攪拌機9之虞 。在過濾處理如此生水的情況時，在過濾裝置的前段設至 除塵機等的前處理裝置，在藉由前處理裝置來除去這些夾 雜物或污泥殘渣後，進行過濾處理。在第9圖顯示內裝有 上述除塵機的過濾裝置。混入有夾雜物或污泥殘渣的污水 由生水供給管3 4流入至過濾槽1內。於是，藉由張設於 過濾槽1的下底部的圓筒狀篩網3 2捕捉除去夾雜物或污 泥殘渣等之大的固形物。已經通過前述篩網3 2的生水流 入至過濾室4。該生水受到濾材層7所固液分離，處理水 是由過濾槽1的頂部排出至外部。受到前述篩網32所捕 捉到夾雜部或污泥殘渣等是藉由內設於篩網3 2內之篩網 -17- (14) (14)200410748 輸送機3 3搬送至洩水排出口 3 5，由此洩水排出口 3 5排 出至外部。 篩網輸送機33是以捲掛有篩網葉片33b的篩網軸 3 3 a與驅動機3 6來構成的。藉由以驅動機3 6轉動篩網軸 3 3 a，來將已被捕捉到的夾雜物或污泥殘渣等由第9圖的 左朝右方向連續移送。在第10圖，在篩網32配設有複數 個生水供給管3 4與複數個洩水排出口 3 5。在混入有多量 的夾雜物或污泥殘渣的生水之情況時，夾雜物或污泥殘渣 等集中在一處所。藉此，當生水流入至過濾室4之際，能 夠防止形成阻抗，生水可在篩網3 2全面均等地供給至過 濾室4。在第1 0圖，在3處所配設生水供給管34、而在 2處所配設洩水排出口 3 5。篩網葉片3 3 b是被分割成4等 分，捲掛於篩網軸33a。第10圖左端的篩網葉片33b (第 1個）是可朝右方向移送。鄰接的篩網葉片33b (第2個 )是可朝左方向移送。第3個篩網葉片33b是可與第1個 相同方向、而第4個篩網葉片3 3 b是可與第2個相同方向 移送。由左端的生水供給管34所流入的夾雜物或污泥殘 渣等被移送至第1個（左側）的洩水排出口 3 5。由中央 的生水供給管3 4所流入的夾雜物或污泥殘渣等分割移送 至左右的洩水排出口 3 5。由右端的生水供給管3 4所流入 的夾雜物或污泥殘渣等被移送至第2個（右側）的洩水排 出口 3 5，而排出至外部。藉由上述的結構，因夾雜物或 污泥殘渣等之大的固形物不會流入至過濾室4內，所以能 夠防止濾材層7的早期堵塞，防止攪拌機9受到損傷。 -18- (15) (15)200410748 在第1 1 A〜1 1 D圖，說明使用於上述實施形態之集水 板2及篩網32的穿孔金屬50a〜50d。 在第11A圖，穿孔金屬50a是具有不銹鋼的薄片51a 、並列配置於薄片51a的圓形孔52a。孔52a的直徑是1 〜3腿〗，設定成較濾材的纖維的直徑（3 mm )小。 在第11B圖，穿孔金屬50b是具有並列配置於薄片 5 1b的圓形孔52b及十字（cross )狀的孔53b。32b、 53b被交互地配置。 在第1 1C圖，穿孔金屬50c是具有並列配置於薄片 5 1c的矩形孔52c。 在第1 1D圖，穿孔金屬50d是具有並列配置於薄片 5 1d的長孔52d、53d。孔52d、53d相互地呈相反傾斜。 〔產業上的利用可能性〕 使用於本發明的橫型高速過濾裝置之纖維濾材，是由 壓縮耐性及空隙率大，能夠調整成適合於生水性狀、處理 速度之比重，故能夠適用於各種領域的生水。例如，可作 爲以高速來將匯集式下水道之雨天時的大量未處理水進行 過濾處理，或使用於進行工業用水的高度處理之精密過濾 ，或水族館的水之淸淨化、游泳池或澡堂的循環過濾等之 各種方面的大容量過濾處理裝置來利用。 【圖式簡單說明】 第1圖是本發明的第1實施形態之橫型高速過濾裝置 -19- (16) (16)200410748 的正面圖。 第2圖是第1圖的橫型高速過濾裝置的側面圖。 第3圖是沿著第1圖的in-ill線之橫型高速過濾裝 置的縱斷面圖。 第4A圖是第1圖的攪拌機的詳細圖；第4B圖是顯 示第4A圖的由箭號IVB所觀看之攪拌葉的正面圖；第 4C圖是顯示第4A圖的由箭號IVC所觀看之攪拌葉的正 面圖。 第5A圖是第1圖的橫型高速過濾裝置的流程圖；第 5B圖是顯示第1圖的橫型高速過濾裝置之散氣管的安裝 位置的圖。 第6圖是第1圖的橫型高速過濾裝置的時間圖。 第7圖是顯示本發明之纖維濾材的單位片的斜視圖。 第8圖是顯示本發明之纖維濾材的單位片的其他實施 例之斜視圖。 第9圖是顯示本發明的第2實施形態之橫型高速過濾 裝置的斷面圖。 第10圖是顯示第9圖的橫型高速過濾裝置之篩網輸 送機的詳細圖。 第11A〜11D圖是顯示使用於第3圖的集水板及第1〇 圖的篩網之穿孔金屬的平面匱1 ° 〔圖號說明〕 1…過濾槽 -20- (17) (17)200410748 2…集水板 3…集水室 4…過濾室 5、6…纖維濾材 5a…第1纖維絲 5 b…第2纖維絲 5c…第3纖維絲 6a…發泡性樹脂板 7…濾、材層 8…散氣管 9…攪拌機 1 0…軸 1 la、1 lb、1 lc…攪拌葉 3 2…篩網 33…篩網輸送機 34…生水供給管 浅水排出口Fig. 9 is a filter device according to a second embodiment of the present invention. Used to treat raw water containing inclusions such as stones or cloth or sludge residues. In this case, if these inclusions or sludge residues are mixed into the filter tank 1, there is a possibility that the filter material layer 7 may be blocked early, or the mixer 9 may be damaged. In the case of filtering the raw water in this way, a pre-processing device such as a dust remover is provided at the front stage of the filtering device, and these inclusions or sludge residues are removed by the pre-processing device, followed by filtering. Fig. 9 shows a filter unit incorporating the above-mentioned dust remover. Sewage mixed with inclusions or sludge residues flows into the filter tank 1 through the raw water supply pipe 34. Then, a large-sized solid matter such as inclusions, sludge residues, etc. is removed by the cylindrical screen 32 2 stretched on the lower bottom of the filter tank 1. The raw water that has passed through the aforementioned screen 32 2 flows into the filtering chamber 4. This raw water is solid-liquid separated by the filter material layer 7, and the treated water is discharged from the top of the filter tank 1 to the outside. The inclusions or sludge residues captured by the aforementioned screen 32 are transferred to the drain outlet 3 through a screen 17- (14) (14) 200410748 which is built in the screen 32 2 5, whereby the drain outlet 35 is discharged to the outside. The screen conveyor 33 is constituted by a screen shaft 3 3 a with a screen blade 33 b wound thereon and a driver 36. By rotating the screen shaft 3 3 a with the driver 36, the trapped inclusions, sludge residues, and the like are continuously transferred from left to right in FIG. 9. In Fig. 10, a plurality of raw water supply pipes 3 4 and a plurality of drain outlets 35 are provided in the screen 32. When raw water containing a large amount of inclusions or sludge residues is mixed, the inclusions or sludge residues are concentrated in one place. Thereby, when the raw water flows into the filter chamber 4, it is possible to prevent the formation of impedance, and the raw water can be uniformly supplied to the filter chamber 4 on the screen 32. In Fig. 10, raw water supply pipes 34 are provided in three places, and drain outlets 35 are provided in two places. The screen blades 3 3 b are divided into four equal parts and are wound on a screen shaft 33 a. The screen blade 33b (the first one) at the left end of Fig. 10 can be moved to the right. Adjacent screen blades 33b (second) can be moved in the left direction. The third screen blade 33b can be moved in the same direction as the first, and the fourth screen blade 33b can be moved in the same direction as the second. Inclusions, sludge residues, etc. flowing into the raw water supply pipe 34 at the left end are transferred to the first (left) drain outlet 3 5. Inflows, sludge residues, and the like flowing in from the central raw water supply pipe 34 are divided and transferred to the left and right drainage outlets 35. Inclusions, sludge residues, etc. flowing in from the raw water supply pipe 34 at the right end are transferred to the second (right) drain outlet 35, and discharged to the outside. With the above-mentioned structure, since large solids such as inclusions and sludge residues do not flow into the filtering chamber 4, it is possible to prevent early clogging of the filter material layer 7 and prevent the mixer 9 from being damaged. -18- (15) (15) 200410748 Figures 1 1 A to 1 1 D illustrate perforated metals 50a to 50d used in the water collecting plate 2 and the screen 32 of the above embodiment. In FIG. 11A, the perforated metal 50a is a stainless steel sheet 51a and a circular hole 52a arranged in parallel to the sheet 51a. The diameter of the hole 52a is 1 to 3 legs, and is set smaller than the diameter (3 mm) of the fiber of the filter medium. In Fig. 11B, the perforated metal 50b has a circular hole 52b and a cross-shaped hole 53b arranged side by side on the sheet 51b. 32b, 53b are configured interactively. In Fig. 11C, the perforated metal 50c is a rectangular hole 52c having a parallel arrangement on the sheet 5 1c. In Fig. 11D, the perforated metal 50d has elongated holes 52d and 53d arranged side by side on the sheet 5 1d. The holes 52d and 53d are inclined opposite to each other. [Industrial Applicability] The fiber filter material used in the horizontal high-speed filter device of the present invention has a large compression resistance and a high porosity, and can be adjusted to a specific gravity suitable for a water-generating state and a processing speed, so it can be applied to various Field of raw water.
