Description

Technical Field

[0002] With the continuous progress of society and the continuous development of industry, environmental pollution issues have gradually emerged in people's vision. Water, as the source of life, is the primary problem people face in environmental pollution. Among them, microbial pollution in water pollution refers to microorganisms that are intentionally cultivated by humans in production and life, but are directly discharged and treated as ordinary sewage after use. The microorganisms that enter the ecosystem in this way multiply in large numbers in the water body in the absence of artificial control, consume a large amount of oxygen in the water body, seriously affect the survival of other organisms in the water body, and then lead to ecological imbalance.

[0003] However, due to the continuous generation of sewage from production and life, the purification of sewage needs to be carried out continuously to avoid affecting people's normal production and life. During the sewage purification process, microorganisms will continue to multiply under sufficient oxygen conditions, and they are difficult to remove by attaching to the water purifier. In addition to the microorganisms that need to be purified, there are also solid suspended matter that needs to be treated. These suspended matter generally also have microorganisms attached to them and cannot be discharged directly, and need to be centrally treated. After a period of use, the solid suspended matter needs to be cleaned.

[0046] Working principle:

[0047] Impurity purification and exhaust stage:

[0048] Referring to the accompanying drawings, Figures 1 to 8 and Fig.10 The specific implementation process shown is:

[0049] In order to continuously purify sewage, firstly, the sewage purifier is installed in the sewage purification room and connected to the indoor power supply. Due to the continuous sewage purification process, the flow rate of water in the sewage purifier decreases suddenly, and the impact of the water flow continuously impacts the sewage purifier, which is prone to shaking. Therefore, two groups of shock-absorbing frames 1 are used to reduce the impact of the shaking of the sewage purifier on the bottom surface. Then, the sewage is introduced into the purification tank 2 through the access pipe 3. At this time, the solenoid valve 6 blocks the slag discharge pipe 5. Therefore, after the sewage enters the purification tank 2, it can only flow from bottom to top, and then be discharged from the outlet pipe 4. Among them, the sewage first passes through the filter element 101 in the purification tank 2, and the filter element 101 blocks the suspended particles in the sewage. After the remaining sewage passes through the filter element 101, it is irradiated by three groups of ultraviolet lamps 9 to kill the microorganisms in the sewage, thereby reducing the microorganisms entering the local ecosystem with the sewage and affecting the ecological balance.

[0050] In the process of sewage purification, when there is sufficient oxygen, microorganisms continue to multiply, and the gases produced by the respiration of microorganisms and the gases dissolved in the water escape. The gases cannot be discharged in time, which affects the safety of sewage purification. The escape of air dissolved in the sewage or the gases produced by the respiration of microorganisms in the sewage will gather on the upper part of the purification tank 2. The accumulation of gases on the upper part of the purification tank 2 or the escape of dissolved gases in the water will help to reduce the air content in the purification tank 2 and further inhibit the reproduction of microorganisms in the purification tank 2. However, the more gas accumulated in the purification tank 2, the greater the pressure of the purification tank 2. This may easily lead to the danger of explosion of the purification tank 2, so it is necessary to exhaust the gas regularly. When the gas pressure in the purification tank 2 increases, the gas in the purification tank 2 pushes the conical head 404 upward, so that the conical head 404 is not tightly matched with the matching piece 405, and the elastic piece 403 is compressed. The gas in the purification tank 2 is discharged into the air through the through hole on the side wall of the exhaust pipe 401. After the gas pressure in the purification tank 2 is balanced with the atmospheric pressure, the elastic piece 403 recovers and synchronously drives the conical head 404 to move downward. The conical head 404 is tightly matched with the matching piece 405 again to complete the sealing process of the purification tank 2.

[0051] During the continuous sewage purification process, a large amount of suspended particles are enriched on the lower surface of the filter element 101. As the use time increases, the enriched suspended particles on the lower surface of the filter element 101 will react on the filter element 101, and the filtering capacity of the filter element 101 decreases. In addition, the flow velocity of the water at the filter element 101 decreases, the flow resistance of the water flow increases, and the impact force of the water flow on the filter element 101 increases, thereby increasing the working pressure of the filter element 101. Therefore, the power assembly 204 is controlled to be started, and the output shaft of the power assembly 204 rotates, synchronously driving the shunt pipe 205 to drive the three brush plates 206 to rotate. The bristles of different lengths at the bottom of the three brush plates 206 contact the filter element 101. During the rotation of the three brush plates 206, the enriched suspended particles in the front of the filter element 101 are disturbed from the back of the filter element 101 to prevent the enriched suspended particles from blocking the filter element 101, thereby ensuring the continuous sewage purification process and reducing the number of shutdowns for sludge cleaning.

[0052] After the sewage has completed the filtration of suspended particles, the sewage continues to flow upward. When the sewage contacts the partition plate 102, the partition plate 102 separates the lower part of the purification tank 2. At this time, the sewage passes through each piston 104 to push up, and each piston 104 drives a counterweight block 105 to move upward until the round hole opened on the side wall of the piston 104 extends out from the sleeve 103, until the block 106 abuts against the lower end of the sleeve 103, and the sewage first enters the piston 104, and then is discharged through the round hole on the side wall of the piston 104. In this way, the sewage is transferred from the bottom of the partition plate 102 to the top of the partition plate 102. At this time, the sewage contains a large number of microorganisms, and the microorganisms In order to reduce the growth and reproduction of microorganisms on the piston 104, a number of spirally twisted guides 107 are arranged in the piston 104, so that the sewage flows in a spiral shape after passing through the guide 107, and when the spirally flowing water passes through the circular hole on the side wall of the piston 104, the water flow initially rushes to the circular hole on the side wall of the piston 104 at an inclined angle, which effectively reduces the attachment of microorganisms around the circular hole on the side wall of the piston 104. Secondly, the guide 107 is set to a structure with a larger upper part and a smaller lower part, which makes the space in the piston 104 larger at the lower part and smaller at the upper part, so that when the water flows through the piston 104, the flow rate of the water flow increases, further reducing the attachment and reproduction of microorganisms at the position of the piston 104.

[0053] Desilting stage:

[0054] Referring to the accompanying drawings, Figures 1 to 9 The specific implementation process shown is:

[0055] After the sewage purifier has been working for a period of time, a large amount of sludge is accumulated at the bottom of the purification tank 2 and needs to be processed. At this time, multiple groups of independently operated sewage purifiers are set up to assist in sewage purification, increase the efficiency of sewage treatment, and provide backup for the sludge purifier. When one group of sewage purifiers is undergoing sludge treatment, the remaining sludge purifiers can still continue to purify sewage. At this time, the sewage stops being injected into the access pipe 3. Since the access pipe 3 is connected to the purification tank 2 in a downwardly inclined manner, and the sewage at this time contains a large number of microorganisms, after the access pipe 3 stops connecting to the sewage, all the sewage on the access pipe 3 flows into the purification tank 2 and does not remain in the access pipe 3, thereby reducing the growth of microorganisms in the access pipe 3.

[0056] Then, the solenoid valve 6 is controlled to open the slag discharge pipe 5. A sludge guide pipe is arranged below the slag discharge pipe 5. The sludge in the purification tank 2 is discharged downwardly and introduced into a special sludge pool for sterilization treatment, and then subjected to harmless processing. Therefore, the sewage and sludge below the partition plate 102 in the purification tank 2 are discharged first, while there is still sewage above the partition plate 102. At this time, the sewage above the partition plate 102 has been sterilized after being irradiated by the ultraviolet lamp 9. At this time, the electric actuator 302 is controlled to start one circle, and the electric actuator 302 is extended, synchronously driving the connecting rod 303 to drive the second annular plate 304 to move downward until the second annular plate 304 The lower surface contacts the bottom surface of the annular water trough 20101. At this time, the sewage above the partition plate 102 enters the annular water trough 20101 through a circle of water pipes 7, and then the sewage enters the diversion chamber 20501 through the confluence groove 20201, and then enters the drainage chamber 20601, and finally sprays out from the water spray port 20602. At this time, the brush plate 206 is still brushing the filter element 101. After water is sprayed out of the water spray port 20602, the filter element 101 is backwashed to wash down the stubborn sludge on the filter element 101, and the bristles of the brush plate 206 are assisted to clean the filter element 101, thereby reducing the residual sludge on the filter element 101.
