DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0045] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features.

[0046] Please refer to Figures 1 to 8 The present application provides a pry integrated water treatment equipment 100, which comprises a frame 1, the frame 1 adopts a steel structure of frame type, which comprises horizontal rods and vertical columns. The pry integrated water treatment equipment 100 further comprises a membrane tank box 2, a dosing unit 3, an aeration unit 4, a backwashing unit 5 and an electric control unit 6 arranged on the frame 1.

[0047] The membrane tank box 2 is used to contain raw water and filter the raw water. The upper end of the membrane tank box 2 in the embodiment of the present application is open, which facilitates the maintenance operation from the upper end of the membrane tank box 2 into the membrane tank box 2.

[0048] As Figure 4 shown, the tank wall of the membrane tank box 2 is provided with a water inlet pipe 71 and a water production pipe 72, the water inlet pipe 71 is connected to raw water to be treated, and the water production pipe 72 discharges treated clean water.

[0049] As Figure 5 and Figure 6 shown, the membrane support 8 is fixedly installed in the membrane tank box 2, the membrane assembly 9 is installed on the membrane support 8, and the water outlet main pipe 91 is arranged on the membrane assembly 9 and communicates with the water production pipe 72.

[0050] The membrane assembly 9 of the embodiment of the present application is composed of a plurality of ultrafiltration membrane sheets, and the clean water is discharged from the water outlet main pipe 91 and the water production pipe 72 after the raw water in the membrane tank box 2 is filtered to obtain the clean water. The membrane support 8 of the present application is fixed in the membrane tank box 2, and only the single membrane sheet needs to be installed on the membrane support 8 during installation, so the installation is convenient. Meanwhile, the membrane support 8 and the membrane tank box 2 are fixed as a whole, which is equivalent to assembling the membrane assembly 9 and the membrane tank box 2 into an integrated structure. Therefore, the present application does not need to hoist and install the membrane assembly 9 and the membrane support 8, and does not need to reserve hoisting space on site, which reduces the requirements for the site conditions such as the floor height during indoor installation, and greatly reduces the construction difficulty.

[0051] Preferably, the membrane assembly 9 of the present application is arranged in upper and lower layers, and the membrane assembly 9 is composed of PTFE ultrafiltration membrane sheets. The upper and lower layer arrangement can reduce the width of the entire membrane tank box 2. Meanwhile, the membrane sheet of the present application adopts PTFE ultrafiltration membrane, and the hydrophilicity of the PTFE membrane material is better than that of the PVDF membrane, the flux is about 1.5 times that of the PVDF membrane, and the service life is more than 3 times that of the PVDF membrane, so the overall investment cost is also better than that of the PVDF membrane system. In addition, the PTFE membrane has high tensile strength, is not easy to break, has good drug resistance, and is less affected by human factors, and has long service life, reduces the replacement frequency, and reduces labor.

[0052] As Figure 7 and Figure 8 shown, the slope sludge discharge hopper 10 is formed below the membrane support 8 in the membrane tank box 2, the top of the slope sludge discharge hopper 10 is large, the bottom is small, and the bottom is connected with a sludge discharge pipe 11.

[0053] After the raw water enters the membrane pool box 2, after being filtered by the ultrafiltration membrane, the inorganic substances such as large particles in the raw water outside the membrane are settled to the bottom of the pool due to gravity and form sludge. The present application is provided with a slope sludge discharge hopper 10 at the bottom of the membrane pool box 2, the slope sludge discharge hopper 10 is a hopper structure formed by making the walls of the bottom of the membrane pool box 2 into a sloping four-wall slope towards the center, compared with the flat bottom membrane pool, the slope sludge discharge hopper 10 at the bottom of the membrane pool box 2 of the present application can effectively collect the sludge to the center of the bottom of the membrane pool box 2, i.e. the center of the bottom of the slope sludge discharge hopper 10, thereby effectively and smoothly discharging the sludge from the sludge discharge pipe 11, improving the sludge discharge effect. The sludge discharge can be automatically controlled by an electric control system, such as installing an electric valve in the sludge discharge pipe 11, and opening the electric valve at regular intervals to discharge the sludge.

[0054] The dosing unit 3 of the pry-mounted integrated water treatment equipment 100 of the present application is in communication with the membrane pool box 2 through a pipeline, and the backwashing unit 5 is in communication with the membrane assembly 9 through a pipeline. The dosing unit 3 generates sodium hypochlorite disinfectant and delivers it into the membrane pool box 2, and the backwashing unit 5 delivers clean water into the membrane assembly 92. The sodium hypochlorite disinfectant is mixed with the clean water delivered by the backwashing unit 5 to form a certain concentration of chemical solution for soaking and backwashing the membrane assembly, so as to restore the original filtration flux of the membrane assembly 9 and ensure the water flow. At the same time, the sodium hypochlorite disinfectant is also input into the raw water end of the water inlet pipe 71 and the clean water pool end of the water outlet pipe 72, the chemical solution injected into the raw water inlet end can inhibit the reproduction of algae or bacteria in the raw water, can effectively control the water quality of the inlet water, and slow down the speed of the membrane assembly being blocked, and the chemical solution injected into the rear-end clean water pool can effectively kill bacteria, pathogens and other microorganisms due to sufficient residence time in the clean water pool. Thus, the water treatment equipment 100 of the present application is strictly designed for filtration and disinfection from the initial inlet water to the terminal water supply, so as to meet the requirements of ensuring the water quality and water quantity.

[0055] The electric control unit 6 of the present application is electrically connected with the dosing unit 3, the fan 43 of the aeration unit 4 and the backwashing unit 5. The electric control unit 6 includes a main control module such as PLC or single-chip microcomputer and peripheral circuit. The PLC or single-chip microcomputer is built-in with a program for controlling the operation of the entire equipment.

[0056] Preferably, as Figure 2As shown, the electric control unit 6 of the present application is embedded on the wall of the membrane tank box 2, and the electric control unit 6 comprises a display screen 61 and a control panel 62. Specifically, the electric control unit 6 of the present application is designed as a power distribution cabinet, and the power distribution cabinet is designed as a whole with the membrane tank box 2, and the whole power distribution cabinet is embedded in the membrane tank box, and a certain space is left between the power distribution cabinet and the wall of the membrane tank box 2 for filling moisture-proof and leakage-proof filler to prevent the influence of water leakage and temperature on the power distribution cabinet; the space above the power distribution cabinet is installed with the display screen 61, and the display screen can realize the display of the running condition of the equipment and the information of water quality monitoring and the like. The space below the power distribution cabinet is installed with the control panel 62, and a plurality of control buttons are arranged on the control panel 62 to control and operate the water treatment equipment 100 of the present application.

[0057] Further, the electric control unit 6 of the present application is also provided with an intelligent voice control system, so that the operation personnel and maintenance personnel of small-scale centralized water supply in rural areas and towns can perform some simple operation control on the equipment through voice, thereby reducing the operation difficulty.

[0058] As shown, Figure 5 The present application is provided with a protective plate 14 around the rack 1 outside the membrane tank box 2, and the protective plate 14 protects the equipment in the rack 1, and the protective plate 14 is provided with a double-door 15, and the double-door 15 provides a larger operation space for the maintenance of the equipment in the rack 1. As shown in the drawings, Figure 5 The four walls 21 of the membrane tank box 2 form a rectangular box, and the bottom of the membrane tank box 2 is surrounded by the inclined sludge discharge hopper 10.

[0059] In combination with Figure 6 and Figure 8 The aeration unit 4 of the present application comprises an aeration main pipe 41, an aeration branch pipe 42 and a fan 43 arranged outside the membrane tank box 2, one end of the aeration main pipe 41 is connected with the fan 42, the other end is connected with the aeration branch pipe 42, the aeration branch pipe 42 is located in the inclined sludge discharge hopper 10 below the membrane support 8, and aeration holes are arranged on the aeration branch pipe 42. The fan 42 introduces and exhausts air into and out of the aeration main pipe 41 and the aeration branch pipe 42, and then the air is discharged into the membrane tank box 2 through the aeration holes on the aeration branch pipe 42 to perform aeration treatment on the raw water.

[0060] In the prior art, the aeration pipe and the membrane assembly 9 are in an integral structure, and in the present application, the aeration pipe, i.e. the aeration main pipe 41 and the aeration branch pipe 42, is arranged separately from the membrane assembly 9, i.e. the water treatment equipment 100 of the present application separates the aeration unit 4 from the membrane assembly 9 and moves downward to the space between the frame of the membrane support 8 of the membrane assembly 9 and the sludge discharge hopper 10. On the one hand, the aeration branch pipe 42 is installed by fully utilizing the slope space of the sludge discharge hopper 10, thereby saving space. At the same time, the aeration pipe is separated from the membrane assembly 9, and when the membrane assembly 9 is replaced, the aeration pipe does not need to be moved and disassembled.

[0061] Reference Figure 2 and Figure 6 The dosing unit 3 of the present application comprises a water softener 31, a brine pump 32, a sodium hypochlorite generator 33 and a first dosing pump 34.

[0062] The output ends of the water softener 31 and the brine pump 32 are connected with the input end of the sodium hypochlorite generator 33, the output end of the sodium hypochlorite generator 33 is used for connecting a liquid storage barrel 201, the input end of the first dosing pump 34 is connected with the liquid storage barrel 201, the output end of the first dosing pump 34 is connected with the membrane pool box 2, and the water softener 31, the brine pump 32, the sodium hypochlorite generator 33 and the first dosing pump 34 are electrically connected with the electric control unit 6.

[0063] The dosing unit 3 is used for disinfection process in the whole water treatment process, and in the embodiment of the present application, specifically:

[0064] The water filtered and purified by the membrane assembly 9 is taken as raw water to enter the water softener 31, and the ion exchange technology is used to remove the excessive calcium and magnesium ions in the water, and then the water enters the sodium hypochlorite generator 33. The sodium hypochlorite generator 33 of the present application is in a combined form, and the dilute brine (prepared in a salt dissolving barrel 202 by using edible salt as raw material to prepare brine with a suitable concentration) is injected into the electrolytic cell in the sodium hypochlorite generator 33 through the brine pump 32, the silicon rectifier in the electrolytic cell is connected with the direct current power supply of the anode and the cathode to electrolyze the dilute brine and the soft water mixture to generate sodium hypochlorite medicine water, and the prepared sodium hypochlorite medicine water is stored in the liquid storage barrel 201. The first dosing pump 34 inputs the sodium hypochlorite medicine water in the liquid storage barrel 201 into the membrane pool box 2 to soak the membrane assembly 9, and combines with backwashing to restore the flux of the membrane assembly 9.

[0065] Preferably, the dosing unit 3 of the present application further comprises a second dosing pump 35 electrically connected with the electric control unit 6, the input end of the second dosing pump 35 is connected with the liquid storage barrel 201, and the output end of the second dosing pump 35 is connected with the water inlet pipe 71. The second dosing pump 35 inputs the sodium hypochlorite medicine water in the liquid storage barrel 201 into the raw water inlet end of the membrane pool box 2, and at the same time, the second dosing pump 35 of the present application also inputs the sodium hypochlorite medicine water in the liquid storage barrel 201 into the clear water pool 500 after the filtration of the membrane assembly 9, so that the present application can disinfect the water inlet and the water outlet of the whole water treatment equipment 100 to improve the water quality of the outlet water.

[0066] As Figure 2As shown, the backwash unit 5 of the present application comprises a backwash pump 51 electrically connected to the electric control unit 6, the input end of the backwash pump 51 is used to connect the backwash water tank 300, and the output end of the backwash pump 51 is connected to the membrane assembly 9. The water inlet end of the backwash water tank 300 of the present application is connected to the clean water filtered by the membrane assembly 9 and put into the backwash water tank 300, and the backwash pump 51 sends the clean water into the membrane assembly 9 to backwash the membrane assembly 9. The backwash pump 51 of the present application is installed on the rack 1 and located below the membrane tank box 2.

[0067] Preferably, as shown in Figure 6 and Figure 7 As shown, the rack 1 of the present application is divided into an upper layer rack 101 and a lower layer rack 102, the membrane tank box 2 is installed on the upper layer rack 101, the fan 43, the water softener 31, the brine pump 32, the sodium hypochlorite generator 33 and the first dosing pump 34 are installed on the lower layer rack 102, and the inclined sludge discharge hopper 10 extends from the upper layer rack 101 to the lower layer rack 102.

[0068] The bottom of the membrane tank box 2 of the present application is an inclined sludge discharge hopper 10 with an inclined slope, after the inclined sludge discharge hopper 10 extends from the upper layer rack 101 to the lower layer rack 102, there is a certain space around the bottom of the membrane tank box 2 outside the rack 1, which can be used as a space for installing the fan 43, the water softener 31, the brine pump 32, the sodium hypochlorite generator 33, the first dosing pump 34, the second dosing pump 35, the backwash pump 51 and other equipment. The remaining space of the rack 1 at the bottom of the membrane tank box is fully utilized, and there is no need to separately set up a equipment room to arrange the above-mentioned equipment, which not only saves space but also saves cost. Thus, the water treatment equipment 100 of the present application can be highly integrated and miniaturized. All units of membrane purification water treatment are integrated on the upper layer rack 101 and the lower layer rack 102 of the rack 1, which reduces the space occupation and is convenient for carrying, installation and maintenance.

[0069] Further, as shown in Figure 4 The present application installs a series of supporting pipes such as the water inlet pipe 71, the water production pipe 72 and the sludge discharge pipe 11 in the same side of the membrane tank box 2, and designs a double-door 15 pipe operation room to facilitate the operation of valves and instruments and the maintenance of pipes.

[0070] Preferably, as shown in Figure 8 The aeration branch pipe 42 of the present application is provided with a plurality of aeration holes, and the aeration branch pipe 42 is provided with a rotary mixing type aeration disc 44 on the aeration holes, and the rotary mixing type aeration disc 44 faces the bottom of the membrane assembly 9. That is, one rotary mixing type aeration disc 44 is installed at each aeration hole position of the aeration branch pipe 42. The rotary mixing type aeration disc 44 can increase the disturbance effect of aeration on the water body, so as to make the membrane filaments of the membrane assembly 9 shake and drop the dirt on the surface of the membrane filaments to slow down the pollution.

[0071] Further, please refer to Figure 4 and Figure 6 The membrane tank body 2 of the present application is provided with a slag overflow pipe 12 at each corner, one end of which is higher than the normal water level in the membrane tank body 2, and the other end of which penetrates the membrane tank body 2. The membrane tank body 2 of the present application is a rectangular tank body, and the four corners of the rectangular tank body are provided with the slag overflow pipe 12. The top of the slag overflow pipe 12 is provided with an overflow pipe opening 121.

[0072] Due to the aeration in the membrane tank body 2, fine particles and suspended solids and other impurities in the water will float to the surface of the upper end of the membrane tank body 2 with the bubbles, forming a layer of scum on the water surface, which needs to be discharged from the overflow pipe opening. The conventional membrane tank is generally provided with an overflow pipe opening at a high position of the membrane tank, which has a good effect on overflowing clean water and the like, but has a poor effect on slag discharge. A large number of field examples prove that a single overflow pipe can only discharge the scum near the pipe opening with the water flow, and the scum at other positions in the tank is difficult to be effectively discharged. The continuous aeration at the bottom of the tank pushes the scum on the water surface to the four corners of the tank wall. Since the tank body is a box structure, the aeration effect at the four corners of the tank body is not as strong as that at the center of the tank body, so the scum on the water surface will gather at the four corners of the tank wall and rotate in the corners for a long time, which cannot be effectively discharged. A slightly improved MBR membrane tank overflow or slag discharge is generally a flow guide groove made around the high liquid level in the tank, which can effectively discharge the scum. However, since a certain space is required for installing the flow guide groove, this structure necessarily increases the area in the tank, resulting in an increase in equipment cost and equipment floor area.

[0073] The embodiment of the present application sets the overflow system of the membrane tank to be provided with a slag overflow pipe 12 with an overflow pipe opening 121 at least at the four corners of the tank to replace the above two overflow system designs. At the same time, as shown in Figure 6 , the bottom of the membrane tank body 2 is provided with a slag overflow pipe 12 with a slope to connect the two vertical slag overflow pipes 12 at the left and right corners of the tank body 2, and then collect the scum on the tank wall at the lower part of the tank body and discharge it outside the tank, as shown in Figure 4 , the slag overflow pipe 12 at the lower part of the tank body discharges the scum outside the membrane tank. This design not only solves the problem that the scum on the water surface cannot be effectively discharged, but also does not occupy the space above the tank, effectively reducing the equipment floor area.

[0074] Preferably, as shown in Figure 9 , the membrane support 8 of the present application comprises a reinforcing support frame 81 surrounding the periphery of the membrane assembly 9, the reinforcing support frame 81 is hollow for connecting the inside of the membrane assembly 9 with the water outlet header 91, and the reinforcing support frame 81 is fixedly connected with the inner wall of the membrane tank body 2.

[0075] The reinforcing support frame 81 fully utilizes the structural components of the membrane assembly 9 itself, uses a part of the membrane support 8 frame of the membrane assembly 9 installed in the membrane tank as a water production pipe, and is fixedly connected with the inner wall of the membrane tank box 2, so that the reinforcing support frame 81 can be used as both an internal reinforcing rib and a pipeline water outlet pipe, one thing with two uses, which reduces the equipment size, saves the internal space of the membrane tank, and reduces the manufacturing cost.

[0076] The reinforcing support frame 81 is fixedly connected with the inner wall of the membrane tank box 2 and used as a reinforcing rib inside the membrane tank, which increases the pulling force of the membrane tank wall plate inside the membrane tank and appropriately reduces the reinforcing rib design inside and outside the traditional membrane tank.

[0077] The pry-mounted integrated water treatment equipment 100 has the following advantages:

[0078] 1. Since the membrane sheet of the membrane assembly 9 is made of PTFE membrane material, it has strong bearing capacity for changes in water quality, and can quickly recover the initial flux after the matching backwashing and chemical washing procedures, so the pretreatment equipment matched with the front end of the traditional ultrafiltration membrane process is completely cancelled, which greatly reduces the cost and land occupation of the equipment.

[0079] 2. The traditional membrane assembly structure is optimized, and the membrane assembly 9 and the membrane tank become an integral whole, so that:

[0080] 1) The installation operation workload and hoisting difficulty are simplified;

[0081] 2) The requirement for the site conditions such as floor height during indoor installation is reduced;

[0082] 3) The structural components of the membrane assembly 9 itself are fully utilized, so that the membrane support 8 can be used as both an internal reinforcing rib and a pipeline water outlet pipe, which fully achieves one thing with multiple uses, reduces the equipment size, and saves the cost;

[0083] 4. The design of the four-corner slag overflow pipe avoids the problems of incomplete slag discharge of the traditional single overflow pipe and space occupation caused by the installation of a flow guide groove, and achieves the effect of effective slag discharge without occupying the effective space in the tank;

[0084] 4. The separate equipment room matched with the traditional membrane system is cancelled, the remaining space below the membrane tank box 2 of the rack 1 is utilized to install the matching operating equipment, which greatly reduces the required land occupation area of the entire equipment and greatly reduces the manufacturing cost of the equipment;

[0085] 5. The integrated intelligent voice control system realizes simple human-computer interaction and more convenient and direct acquisition of required operation guide information, and avoids professional and complex operation steps and procedures.

[0086] For example, Figure 10As shown, the application further provides an integrated water treatment system 400, comprising the above-mentioned skid-mounted integrated water treatment device 100, further comprising a backwashing water tank 300 and an integrated tank 200 integrated with a salt dissolving barrel 202 and a liquid storage barrel 201, wherein the backwashing water tank 300 and the integrated tank 200 are connected to the skid-mounted integrated water treatment device 100 through pipelines. Thus, the integrated water treatment system 400 has the advantages of the above-mentioned skid-mounted integrated water treatment device 100, and does not need to additionally build a backwashing pool, a salt dissolving pool and a liquid storage pool on site, thereby improving the installation efficiency of the system.

[0087] The skid-mounted integrated water treatment device 100 and the integrated water treatment system 400 provided by the embodiments of the application integrate the membrane pool tank 2, the dosing unit 3, the aeration unit 4, the backwashing unit 5 and the electric control unit 6 on the rack 1, so that the entire water treatment device 100 is integrated, a separate membrane pool and a separate equipment room are not needed, the site occupation is reduced, and the device is convenient to carry and install. The electric control unit 6 is intelligent and simple to operate, and is suitable for rural water treatment systems.
