Description

Technical Field

[0001] The invention relates to the field of municipal water supply treatment, in particular to a full-process water treatment integrated pool. Background Art

[0002] With the official implementation of my country's new "Standard for Drinking Water Quality" (GB5749-2022), water pollution issues have become increasingly prominent, and many water plants that rely on traditional water treatment processes are in urgent need of technical upgrades and transformations. Traditional water treatment methods, such as sedimentation, filtration, and disinfection, although they ensure the safety of water supply, have limitations in terms of the removal of tiny particles, organic pollutants, and pathogenic microorganisms. In particular, many old water plants in my country, due to the technical level and concept limitations of the construction period, their process flow, equipment selection, and layout can no longer meet the new water quality standards.

[0003] At present, ultrafiltration membrane treatment technology has been widely used in the field of municipal water supply due to its ability to efficiently remove suspended matter, microorganisms and organic matter in water. Ultrafiltration membrane technology can achieve deep purification of water bodies at a lower operating pressure, effectively avoiding tiny particles and organic pollutants that are difficult to remove with traditional filtration technology. A full-process water treatment process with membrane treatment technology as the core is as follows: mixing, flocculation → flotation → sand filtration → booster pump room → ultrafiltration membrane filtration → disinfection contact pool → product water pool → product water pump room. However, ultrafiltration membrane systems usually require a large space to accommodate membrane components, pump stations, cleaning equipment, etc. If each treatment unit is set up independently, it will not only increase the land area, but also increase the length and complexity of the connecting pipelines, resulting in an increase in construction and maintenance costs, and also increase the difficulty of management. It is also sensitive to changes in water quality and requires a strict water quality monitoring and adjustment system, which increases the complexity and cost of water plant construction and operation. Therefore, there is an urgent need for an efficient, integrated and compact water treatment structure to adapt to the limitations of the existing site and reduce construction and operation costs. Summary of the invention

[0004] In order to solve the above problems, the technical solution of the present invention is a full-process water treatment integrated pool, which adopts a full-process membrane water treatment process to improve water quality, intensively arranges various process units and auxiliary production facilities, and adopts multi-condition coupling switching to maximize the use of hydraulic process water pressure, thereby achieving water quality improvement, intensive, and low-carbon municipal water supply treatment, which is used for municipal water supply treatment.

[0005] The present invention specifically adopts the following technical solutions:

[0006] A comprehensive water treatment pool with a full process, including a mixing well, a mechanical flocculation well, a flotation filtration pool, an ultrafiltration workshop, a lower clear water pool, a pump room, an auxiliary workshop and a comprehensive dosing room;

[0007] The mixing and stirring well is close to the mechanical flocculation well. The mixing and stirring well adopts mechanical mixing and mixing to evenly mix the coagulant added to the influent. The effluent enters the mechanical flocculation well. Mechanical mixing and flocculation with different speed gradients are adopted to make the effluent of the mixing well flocculate. The effluent enters the main inlet channel of the flotation filter. The flotation filter is symmetrically arranged on both sides of the mixing and stirring well and the mechanical flocculation well. The single-grid flotation filter evenly receives the effluent of the flocculation well through the main inlet channel and the inlet distribution channel. The flotation filter is arranged with a dissolved air contact area, an air flotation separation area, a filtration area, a bread pipe and a water and air distribution vertical pipe, and a bottom distribution channel, wherein the bread pipe and the water and air distribution vertical pipe, and the bottom distribution channel are vertically arranged in the same grid of the flotation filter body; the lower stacked clear water tank is stacked as a whole below the flotation filter, the comprehensive dosing room, and the ultrafiltration workshop.

[0008] Furthermore, a water inlet gate is set between the main water inlet channel and each water inlet distribution channel to control the water inlet of each compartment, and can be isolated from the main water inlet channel during maintenance and backwashing. A water distribution weir is set in each water inlet distribution channel to evenly control the water inlet of each compartment.

[0009] Furthermore, the dissolved air contact area of ​​each flotation filter tank is close to the water inlet distribution channel and connected through the bottom water hole. A dissolved air release device is set near the bottom connecting hole at the bottom of the dissolved air contact area. The water flow section of the dissolved air contact area gradually increases from bottom to top, showing a diffusion shape, which is convenient for the uniform release of dissolved air and stabilizes the water flow. The rising flow rate of the contact area is 10mm / s-20mm / s. A stainless steel weir plate is set on the upper part of the dissolved air contact area, and the weir flow turns over the water and enters the flotation separation area.

[0012] Furthermore, the filtered water of the floating filter tank passes through the bread pipe, the water and air distribution vertical pipe, and enters the bottom distribution channel. The outlet pipe of the bottom distribution channel is connected to the water outlet overflow well.

[0013] Furthermore, the outlet pipe of the bottom distribution channel is connected to the outlet overflow well; the water from the outlet overflow well enters the outlet main channel; the outlet main channel is overlapped under the lower part of the pipe gallery; wherein the floating filter tanks are arranged in double rows, and the pipe gallery is arranged between the two rows.

[0014] Furthermore, the mixing well adopts mechanical mixing, and the G value is not less than 500s -1 , the volume cycle number is not less than 1.5 times, and the stirring uniformity is not less than 90%.

[0015] Furthermore, the mechanical flocculation well adopts paddle stirring, which is divided into two stages. The linear velocity of the center point of the first-stage flocculation paddle is about 0.50m / s, and the linear velocity of the center point of the second-stage flocculation paddle is about 0.35m / s. The linear velocity of the center point of the first and second-stage flocculation paddles can be adjusted in the range of 0.20-0.50m / s.

[0016] Furthermore, the outflow overflow well is provided with an outflow weir, and the outflow water enters the outflow main channel after the outflow weir. The outflow main channel is stacked under the lower part of the pipe gallery.

[0017] Furthermore, a backwash water storage tank is stacked on the top of the pipe gallery to provide backwash water for the floating filter tank; a blower for backwashing the floating filter tank and an air compressor for pneumatic valves are arranged on the upper layer of the pipe gallery, and a pressure water pipe, a dissolved gas tank, a dissolved gas water pipe, a bottom distribution channel outlet pipe, an outlet overflow well, and a backwash water pipe are arranged on the lower layer; the floating filter tank outlet main channel is stacked under the bottom of the pipe gallery. The backwash water pipe is arranged in the middle of the lower layer of the pipe gallery, and an inspection walkway is set on the upper part of the backwash water pipe. Pressure water pipes and dissolved gas tanks are arranged on both sides of the backwash water pipe. A dissolved gas water pipe is set between the self-dissolving gas tank and the dissolved gas release device of the floating filter tank.

[0018] Furthermore, the auxiliary workshop is arranged with a water suction channel and a semi-underground pump room; the main outlet channel is connected to the water suction channel of the auxiliary workshop through a channel, and the water suction channel is arranged to surpass the ultrafiltration outlet pipe, and a first electric valve is arranged on the ultrafiltration outlet pipe to switch the water outlet to the water inlet pipe of the lower clear water tank.

[0019] Furthermore, the semi-underground pump room is provided with a dissolved gas tank reflux pump, a filter tank backwashing booster pump, and an ultrafiltration booster pump for absorbing water from the water suction channel; the dissolved gas tank reflux pump sucks and filters water from the water suction channel to the dissolved gas tank at the lower layer of the pipe gallery; the filter tank backwashing booster pump sucks and filters water from the water suction channel to the backwashing water storage tank on the top of the pipe gallery. The ultrafiltration booster pump sucks and filters water from the water suction channel to the tank-type inorganic or vertical organic ultrafiltration membrane assembly.

[0020] Furthermore, the ultrafiltration workshop is arranged with tank-type inorganic or vertical organic ultrafiltration membrane components to receive and process the effluent from the outlet main of the ultrafiltration booster pump, and the ultrafiltration effluent enters the lower clear water tank through a pipeline connection.

[0021] Furthermore, the ultrafiltration booster pump has an override pipe that overrides the flotation filter tank on its outlet main pipe, and a second electric valve is provided on the override pipe. When the raw water quality is good and the pressure is sufficient, the raw water can be switched to be directly transported to the ultrafiltration treatment process, thereby realizing a short process and energy saving.

[0022] Furthermore, the comprehensive dosing room is arranged between the auxiliary workshop and the ultrafiltration workshop, and is equipped with a PAC dosing system, a sodium hypochlorite system, a chemical storage tank, and a compressed air system.

[0023] Furthermore, the pump room is equipped with a water supply pump, an ultrafiltration backwash pump, a CIP circulating water pump, and a CIP chemical agent storage tank; the water supply pump is used to draw water from the lower clear water tank to supply water to the user; the ultrafiltration backwash pump is used to draw water from the ultrafiltration backwash water storage tank to provide backwash water to the ultrafiltration membrane; the ultrafiltration backwash water storage tank is embedded in the lower clear water tank and isolated from the lower clear water tank. The CIP circulating water pump draws water from the CIP chemical agent storage tank to provide CIP chemical cleaning water to the tank-type inorganic or vertical organic ultrafiltration membrane assembly.

[0024] Furthermore, different water treatment process flows can be realized through valve switching and automatic switching control of each system:

[0025] 1) Close the first electric valve and the second electric valve, and start the ultrafiltration booster pump to realize the full process of coagulation, flotation, filtration, ultrafiltration and disinfection to ensure safe water supply;

[0026] 2) When the tap water quality is good, open the first electric valve, close the electric valve, and stop the ultrafiltration booster pump to achieve the water treatment process of coagulation, flotation, filtration, and disinfection;

[0027] 3) When the incoming water pressure is sufficient and the water quality is good, close the first electric valve, open the second electric valve, and stop the ultrafiltration booster pump to achieve a short-process ultrafiltration and disinfection water treatment process.

[0028] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0029] The full-process water treatment integrated pool in the present invention integrates multiple water treatment process units (such as mixing wells, mechanical flocculation wells, flotation filtration tanks, etc.) into one structure. This compact layout can reduce the floor space and reduce construction and maintenance costs. The close arrangement of the mixing wells and mechanical flocculation wells ensures that the flow distance of raw water between different processes is minimized, thereby improving the efficiency of water treatment. By reducing the diversion and delay time of the water flow, the flow rate and response speed of the entire treatment process can be improved.

[0030] By setting valves, the water treatment process can be switched flexibly. According to the water quality and pressure conditions, the system can switch between full-process water treatment and short-process ultrafiltration to make full use of hydraulic resources. Equipped with a variety of pumps (such as ultrafiltration booster pumps, backwash pumps, etc.), the flow and pressure can be automatically adjusted according to demand to adapt to different water treatment modes. The above dynamic adjustment capabilities make the water treatment process more flexible and efficient.

[0031] The gradually increasing water flow section in the pool structure ensures uniform gas release and water flow stability, thereby optimizing hydraulic conditions and improving the efficiency of flotation separation. The above design reduces water flow resistance and improves treatment efficiency. The relative position arrangement of the lower clear water pool and other process units uses gravity to enhance water flow, so that the entire system can rely on gravity and water pressure to drive water flow during operation, reducing energy consumption.

[0032] In summary, the present invention adopts a full-process water treatment with membrane water treatment technology as the core to improve water quality, intensively arranges various process units and auxiliary production facilities, and adopts multi-condition coupling switching to maximize the use of hydraulic process water pressure, thereby achieving water quality improvement, intensive, and low-carbon municipal water supply treatment.
