Description

Technical Field

[0001] The invention belongs to the technical field of municipal engineering facilities, and in particular relates to a multifunctional integrated water distribution well for a water purification plant. Background Art

[0002] In a water treatment plant, the same water treatment structure is usually divided into multiple groups or compartments, and these parallel-operated water treatment structures need to be evenly distributed with water, so a water distribution well is often set up in front of the water treatment structure. Currently, water treatment plants usually set up two partition walls in the water distribution well. The incoming water first enters the middle water inlet chamber. When the water level rises to the height of the partition wall, the water enters the distribution chambers on both sides to evenly distribute the water for the subsequent treatment system.

[0003] At present, the distribution wells commonly used in water treatment plants only have the function of distributing water. However, the incoming water to the water treatment plant usually has seasonal water quality changes. In summer, the amount of organic matter in the incoming water tends to increase, and the treatment load of the water treatment plant will increase. At the same time, the new national standard "Sanitary Standard for Drinking Water" (GB5749-2022) has added new water quality indicators such as 2-methylisoborneol and geosmin, and the requirements for the effluent quality of the water treatment plant are getting higher and higher. At this time, the incoming water stays in the distribution well for a short time and only enters the subsequent treatment system after distributing the flow. This will inevitably increase the treatment load of the subsequent system and cause lag in the entire treatment system, especially in summer. A large number of algae will breed in the water body, resulting in a reduction in the flow section, affecting the effluent quality. In severe cases, it may even clog the treatment structure, and production needs to be stopped to clean the algae. Summary of the invention

An electric flushing valve 52 is installed on the part of the flushing pipe outside the flushing chamber. The end of the flushing pipe inside the flushing chamber is provided with multiple rows of flushing holes 54. Specifically, the row spacing between the multiple rows of flushing holes 54 is 50-100 mm. The flushing hole has an aperture of 20-30 mm, and a flushing elbow 53 is connected to the end of the flushing pipe. A flushing outlet hole 1522 is provided on the side wall of the fence cover 152 near the flushing elbow 53. Specifically, the horizontal distance between the two sides of the flushing outlet hole 1522 and the end of the flushing pipe is 300-500 mm. The height of the flushing outlet hole 1522 is the same as that of the fence cover 152. The flushing elbow is bent upward and extends into the fence cover 152 through the flushing outlet hole 1522;

[0087] A flushing confluence hole 72 is provided at the bottom of one side of the mud discharge chamber close to the flushing chamber. Specifically, the height of the flushing confluence hole 72 is 400-600mm, and the bottom of the flushing confluence hole 72 is flush with the bottom of the mud discharge chamber. The bottom of the flushing chamber and the bottom of the mud discharge chamber are connected through the flushing confluence hole. The width of the flushing confluence hole is the same as the width of the mud discharge chamber. A mud outlet pipe 73 is provided at the bottom of the side wall of one side of the mud discharge chamber, wherein the mud outlet pipe 73 is made of carbon steel or stainless steel, and is arranged on the same side as the water outlet pipe of the water distribution chamber.

[0088] By providing a flushing pipe, an electric flushing valve 52 and a flushing hole, the algae attached to the reciprocating fence assembly 15 can be efficiently and comprehensively flushed without stopping production, and discharged to the mud discharge chamber in time and discharged through the mud outlet pipe to prevent clogging of the entire water purification system, thereby facilitating operation and management. In addition, due to the presence of the fence cover 152, the flushing water sprayed from the flushing pipe and the flushing hole can be prevented from spraying onto the drive motor 1515.

[0089] For ease of understanding, the working process of the present invention is described in detail below:

[0090] First, potassium permanganate and other strong oxidants are added to the water inlet pipe 11, and the strong oxidants and the water are fully mixed by the pressure of the water, and then enter the water inlet chamber 1. The strong oxidants can oxidize the macromolecular pollutants in the water into small molecular pollutants in the water inlet chamber 1 due to their strong oxidizing properties, and can also oxidize and remove some algae;

[0091] The water flows into the water inlet chamber 1 and passes through the reciprocating fence assembly 15. Driven by the driving motor 1515, the reciprocating fence 151 in the fence cover 152 starts to rotate, and the algae are intercepted in the gap between the bars of the transmission fence 1511 of the reciprocating fence 151, which can prevent the algae from clogging the subsequent water purification system.

[0092] After that, the water flows through the circulating reciprocating fence assembly 15, is screened, and enters the mixing chamber 21 through the water outlet hole of the water inlet chamber 1. The powdered activated carbon is added into the mixing chamber 21 through the dosing main pipe 22 and the dosing branch pipe 23. The powdered activated carbon powder is fully mixed with the water in the mixing chamber 21, and then overflows the U-shaped trough-shaped mixing chamber 21 and enters the reaction chamber 2. In the reaction chamber 2, the powdered activated carbon adsorbs the oxidized small molecular pollutants in the water.

[0093] Then the water flows through the reaction chamber outlet hole 25 at the bottom of the reaction chamber 2 and enters the sedimentation chamber. The powdered activated carbon with high adsorption of small molecular pollutants is precipitated in the center of the sludge hopper under the action of gravity. At this time, the pollutants in the water are removed to a high degree, which can reduce the processing load of the subsequent overall water purification system.

[0094] The water in the sedimentation chamber accumulates continuously, and after moving upward and over the overflow weir, it is evenly distributed to the two small chambers in the water distribution chamber, and then enters the subsequent water purification system through the outlet pipe at the bottom of the small chamber;

[0095] After running for a period of time, the reciprocating fence assembly 15 intercepts more and more algae. Due to the increase in water loss, the liquid level in the water inlet chamber 1 becomes higher and higher. When the liquid level difference displayed by the first liquid level gauge 14 of the water inlet chamber 1 and the second liquid level gauge 24 of the reaction chamber 2 reaches a preset value, the electric flushing valve automatically opens, and the high-pressure flushing water efficiently flushes the reciprocating fence 151 through the flushing pipe and the flushing hole. At this time, the reciprocating fence 151 still operates normally, and the algae attached to the reciprocating fence 151 can be efficiently and comprehensively flushed without stopping production. The sprayed washing water is blocked by the fence cover 152 and will not be sprayed onto the drive motor 1515.

[0096] The flushing water flows to the bottom of the flushing chamber through the flushing outlet hole 1522 on the fence cover 152, then enters the mud discharge chamber through the flushing confluence hole at the bottom of the flushing chamber, and is discharged to the outside through the mud discharge pipe at the bottom of the mud discharge chamber;

[0097] After running for a period of time, more and more sludge is deposited in the sludge hopper. When the mud level meter 31 in the sedimentation chamber shows a high mud level reaching a preset value, the electric mud discharge valve 61 automatically opens, and the sludge in the sludge hopper is discharged to the mud discharge chamber through the mud discharge pipe under the action of static pressure, and finally discharged to the outside.

[0098] The present invention can, under the premise of ensuring that the water distribution well is evenly distributed, add a strong oxidant through the dosing pipe 12 and add powdered activated carbon to the mixing chamber 21 to pre-treat the water quality, so that the pollutants in the water are efficiently removed, reducing the processing load of the subsequent water purification system; and by setting a circulating reciprocating fence component 15, the algae can be effectively intercepted, and at the same time, the algae attached to the circulating reciprocating fence component 15 can be efficiently and comprehensively flushed without stopping production, so as to avoid the algae from affecting the subsequent water purification system, thereby achieving efficient removal of pollutants such as algae, organic matter, 2-methylisoborneol, and geosmin, thereby ensuring that the water quality meets the standards, and can even effectively improve the taste, meeting the higher requirements of the new national standard "Sanitary Standard for Drinking Water" (GB5749-2022); the present invention integrates the functions of water quality pretreatment, intercepting algae, flushing the circulating reciprocating fence component, discharging mud, and evenly distributing water, can realize full-automatic operation, reduce labor costs, and facilitate daily operation management and maintenance of the water purification plant.

[0099] The above description is only an embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the application scope of the present invention shall be included in the protection scope of the present invention.
