Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to an algae-bacteria sewage treatment device. Background Art

[0002] Traditional sewage treatment methods are costly and produce greenhouse gases such as carbon dioxide and methane during the treatment process. In some developed countries, sewage treatment plants have been listed as key emission reduction industries due to their obvious carbon reduction benefits. The removal of new pollutants in sewage has also driven the development of sewage treatment. The algae-bacteria treatment system can not only remove new pollutants in sewage, but also reduce carbon emissions.

[0003] At present, when algae and bacteria are used to treat sewage, the algae and bacteria are usually placed inside the sewage treatment room for cultivation. The sewage is passed through the sewage treatment room and the synergistic physiological functions of algae and bacteria are used to purify the sewage. Specifically, algae plants use CO2 and NH4 in water through photosynthesis. + PO4 3- and other nutrients, synthesize their own cellular substances and release O2; aerobic bacteria use the O2 in the water to decompose and transform organic pollutants, producing CO2 and the above-mentioned nutrients to maintain the growth and reproduction of algae. This cycle repeats itself to achieve the biological purification of sewage.

[0004] However, in the actual sewage treatment process, it is found that as the sewage treatment proceeds, the algae and fungi gradually grow and the space they occupy gradually increases. If they are not treated in time, it is easy to cause secondary pollution. At the same time, the volume of the algae and fungi increases and accumulates, which will cause the light intensity of the algae and fungi located inside to be limited. Some algae and fungi will adhere to the inner wall of the sewage treatment room, which will also affect the light of the algae and fungi. The efficiency of algae and fungi in treating sewage depends on many factors such as solar radiation, temperature, degree of pollution and residence time. The light intensity will have a greater impact on the sewage treatment efficiency. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5 A device for treating algae and bacteria sewage comprises a sewage treatment chamber 1, wherein the sewage treatment chamber 1 comprises a main body and two covers, wherein the two covers are respectively threadedly connected to the two ends of the main body, and the interior of the sewage treatment chamber 1 can be cleaned or algae and bacteria can be placed by unscrewing the covers, and further comprises a plurality of algae and bacteria partition plates 2, a plurality of water inlet pipes 3, a plurality of water outlet pipes 4, an excess algae and bacteria discharge system 100 and a light angle adaptation component 300.

[0031] See also Figure 1 , Figure 4 and Figure 5 The algae and bacteria separation plate 2 is fixedly installed on the inner bottom wall of the sewage treatment chamber 1, and is used to separate the algae and bacteria. A plurality of algae and bacteria separation plates 2 are equidistantly arranged, which can separate and limit the algae and bacteria, so that the algae and bacteria are evenly distributed at the bottom of the sewage treatment chamber 1, and the algae and bacteria are prevented from accumulating on the side of the sewage treatment chamber 1 with a lower height under the action of gravity, resulting in the algae and bacteria inside the accumulation place. The light and gas environment are limited, and the sewage treatment effect of the algae and bacteria is reduced.

[0032] See also Figures 1 to 5 The water inlet pipe 3 and the water outlet pipe 4 are respectively connected to the two sides of the sewage treatment chamber 1, and valves are arranged on the water inlet pipe 3 and the water outlet pipe 4. The sewage treatment chamber 1 is inclined, and the water inlet pipe 3 is connected to the lower side of the sewage treatment chamber 1, and the water outlet pipe 4 is connected to the higher side of the sewage treatment chamber 1. The water inlet pipe 3 is connected to the external sewage pump, and the sewage is sent into the sewage treatment chamber 1 through the water inlet pipe 3 by the sewage pump. The sewage flows from bottom to top and stays in the sewage treatment chamber 1 for a long time, so that the algae and bacteria can fully carry out biological purification on the sewage. The water inlet pipe 3 and the water outlet pipe 4 can be opened and closed by the valve to control the flow of sewage.

[0033] See also Figure 1 , Figure 4 and Figure 5The excess algae and fungi discharge system 100 includes a plurality of algae and fungi discharge pipes 101, a plurality of algae and fungi push-pull plates 102 and a discharge pipe opening and closing assembly 200. The algae and fungi discharge pipe 101 is connected to the sewage treatment chamber 1. A stop cover 103 is sealed and installed at one end of the algae and fungi discharge pipe 101 away from the sewage treatment chamber 1. The periphery of the stop cover 103 is provided with anti-slip grooves 104, which are convenient for rotating the stop cover 103 to open and close the algae and fungi discharge pipe 101. The algae and fungi push-pull plates 102 are fixedly connected with a push rod 105. The push rod 105 and the stop cover 103 are in sealed sliding cooperation. A plurality of filter holes are provided on the algae and fungi push-pull plates 102. The algae and fungi push-pull plates 102 and the algae and fungi discharge pipe 101 are sealed and slidable. 1 is in sliding cooperation, the curvature of the algae and bacteria push-pull plate 102 corresponds to the curvature of the sewage treatment chamber 1. During the sewage treatment process, the algae and bacteria push-pull plate 102 fits with the inner wall of the sewage treatment chamber 1 to reduce the space occupied. Pulling the push rod 105 can make the algae and bacteria push-pull plate 102 approach the discharge port of the algae and bacteria discharge pipe 101, and pull the excess algae and bacteria at a higher position into the algae and bacteria discharge pipe 101, so that the sewage passes through the filter holes and the algae and bacteria are retained between the algae and bacteria push-pull plate 102 and the baffle 103. Opening the baffle 103 can clean out the excess algae and bacteria cleaned into the algae and bacteria discharge pipe 101 for other sewage treatment or other purposes.

[0034] See also Figures 1 to 4 The discharge pipe opening and closing assembly 200 includes a rotating shaft 201 and a plurality of baffles 202. The rotating shaft 201 is sealed and rotatably connected to the sewage treatment chamber 1. The sewage treatment chamber 1 is in the shape of a circular tube. The rotating shaft 201 and the sewage treatment chamber 1 are concentric. One end of the rotating shaft 201 passes through the sewage treatment chamber 1 and is fixedly connected with a rotating handle 203. A reinforcement seat is fixedly installed on the inner wall of the sewage treatment chamber 1 on a side away from the rotating handle 203. The rotating shaft 201 and the reinforcement seat are in rotational cooperation, and the rotating shaft 201 can be supported to ensure the stability of the rotating shaft 201. The plurality of baffles 202 are fixedly connected by a connecting rod 204, and the plurality of baffles 202 are fixedly connected to the rotating shaft 201 by a plurality of rotating rods 205. The baffles 202 and the inner wall of the sewage treatment chamber 1 are in a sealed sliding cooperation. The area of ​​the baffles 202 is adapted to the size of the algae and fungus discharge pipe 101.

[0035] The rotating shaft 201 can be rotated by rotating the handle 203, thereby driving the baffle 202 to slide along the inner wall of the sewage treatment chamber 1. When the baffle 202 slides to the connection point between the algae and fungi discharge pipe 101 and the sewage treatment chamber 1, the algae and fungi discharge pipe 101 can be closed to reduce the sewage in the sewage treatment chamber 1 from flowing out of the algae and fungi discharge pipe 101. The algae and fungi discharge pipe 101 is located between two adjacent algae and fungi partition plates 2. Algae and fungi can be added to the interior of the sewage treatment chamber 1 through the algae and fungi discharge pipe 101. The algae and fungi push-pull plate 102 is pulled until it is close to the baffle cover 103, and the rotating shaft 20 1 drives the baffle 202 to close the algae and bacteria discharge pipe 101, unscrews the baffle 103, puts the algae and bacteria into the algae and bacteria discharge pipe 101, tightens the baffle 103 to close the algae and bacteria discharge pipe 101, rotates the rotating shaft 201 to drive the baffle 202 to rise to release the blockage of the algae and bacteria discharge pipe 101, pushes the algae and bacteria push-pull plate 102 to push the algae and bacteria in the algae and bacteria discharge pipe 101 into the interior of the sewage treatment chamber 1 and falls between two adjacent algae and bacteria partition plates 2 to purify the sewage, and the algae and bacteria push-pull plate 102 continues to move until it is close to the inner wall of the sewage treatment chamber 1.

[0036] It should be noted that after the blocking cover 103 is unscrewed, the push rod 105 can be slid off the blocking cover 103, so that the algae and fungus push-pull plate 102 and the blocking cover 103 can be disassembled, and the algae and fungus push-pull plate 102 can be replaced or other operations can be performed;

[0037] See also Figures 4 to 5 A baffle 206 is fixedly installed at one end of the sewage treatment chamber 1 close to the rotating handle 203, and the baffle 206 contacts the rotating handle 203. When the rotating handle 203 is rotated to contact the baffle 206, the baffle 202 just closes the algae and fungus discharge pipe 101, and the rotating handle 203 is positioned by the baffle 206. The rotation damping between the rotating shaft 201 and the sewage treatment chamber 1 is relatively large. When not subjected to external force, the baffle 202 can be in a relatively stable state;

[0038] When the baffle 202 is rotated by rotating the handle 203, the baffle 202 and the connecting rod 204 clean the inner wall of the sewage treatment chamber 1 to a certain extent, scrape off the algae and fungi attached thereon, ensure the illumination of the algae and fungi, and facilitate observation of the sewage treatment situation inside the sewage treatment chamber 1;

[0039] The sewage treatment chamber 1, the baffle 202, the connecting rod 204, the rotating shaft 201, the rotating rod 205, the push rod 105 and the algae and fungus push-pull plate 102 are all made of transparent materials, which can clearly observe the algae and fungi and sewage in the sewage treatment chamber 1 while reducing the impact on light.

[0040] See also Figures 1 to 5The light angle adaptation component 300 includes a base 301, a swivel seat 302 and a cylinder 303. The swivel seat 302 is fixedly installed on the top of the base 301, and the cylinder 303 is rotatably installed on the top of the base 301. Rotating frames 304 are installed on both sides of the bottom of the sewage treatment chamber 1. The top of the swivel seat 302 and the top output end of the cylinder 303 are rotatably connected to the corresponding rotating frames 304 respectively. As the cylinder 303 is extended and rotated, the side of the sewage treatment chamber 1 connected to the cylinder 303 can be driven to rotate around the swivel seat 302, thereby adjusting the angle of the sewage treatment chamber 1 so that it rotates with the deviation of sunlight to ensure the light required for the growth of algae and fungi. When the cylinder 303 is in a contracted state, the side of the sewage treatment chamber 1 connected to it is still higher than the other side, ensuring that the height of the outlet pipe 4 is higher than the height of the inlet pipe 3, so that the sewage stays in the sewage treatment chamber 1 for a longer time.

[0041] See also Figures 1 to 3 It should be noted that the top of the higher side of the sewage treatment chamber 1 is connected with an air pipe valve 5, and the height of the connection point between the air pipe valve 5 and the sewage treatment chamber 1 is higher than the height of the connection point between the water outlet pipe 4 and the sewage treatment chamber 1. A certain gas space is formed at the connection point between the air pipe valve 5 and the sewage treatment chamber 1. The air pipe valve 5 can be opened regularly to discharge the excess gas in the sewage treatment chamber 1, so as to avoid excessive air pressure inside the sewage treatment chamber 1, which may cause damage to the sewage treatment chamber 1 or affect the flow of sewage or the growth of algae and fungi.

[0042] See also Figures 1 to 3 The sewage treatment chamber 1 is connected with a test tube, and a pH tester 6 is installed inside the test tube. The probe of the pH tester 6 extends into the sewage treatment chamber 1 to perform a pH test on the sewage, thereby making a more intuitive observation of the growth of algae and bacteria and the purification of sewage;

[0043] See also Figures 1 to 5 The bottom of the sewage treatment chamber 1 is connected with a plurality of drain pipes 7, on which valves are arranged, and the drain pipes 7 can be opened and closed by the valves. The drain pipes 7 can be used to quickly discharge the sewage inside the sewage treatment chamber 1 in certain special circumstances, such as when cleaning the inside of the sewage treatment chamber 1 or replacing algae and bacteria.

[0044] When the algae-bacteria sewage treatment device is used to treat sewage, the device is placed outdoors or in a place with sufficient light. First, the cover 103 is opened, and the algae and fungi are placed into the sewage treatment chamber 1 through the algae-bacteria discharge pipe 101. The algae and fungi are in the space between the multiple algae-bacteria partition plates 2. The cover 103 is tightened to seal the algae-bacteria discharge pipe 101, and the push rod 105 is pushed to make the algae-bacteria push-pull plate 102 close to the inner wall of the sewage treatment chamber 1. Then the water inlet pipe 3 is connected to the external sewage pump, and the water outlet pipe 4 is connected to the clean water bucket or other clean water collection device. The external sewage pump sends the sewage into the sewage treatment chamber 1 through the water inlet pipe 3. The sewage slowly passes through the sewage treatment chamber 1, and the algae plants utilize CO2 and NH4 in the water through photosynthesis. + PO4 3- and other nutrients, synthesize their own cell substances and release O2; aerobic bacteria use O2 in the water to decompose and transform organic pollutants, produce CO2 and the above nutrients to maintain the growth and reproduction of algae, and so on and so forth, to achieve the biological purification of sewage, and the purified water is discharged through the outlet pipe 4 for collection or utilization. In this process, the air pipe valve 5 is opened regularly to discharge the excess air inside the sewage treatment chamber 1, and the PH tester 6 performs PH test on the sewage. At the same time, during the sewage treatment process, the cylinder 303 is opened, and the cylinder 303 drives the sewage treatment chamber 1 to rotate around the rotating seat 302, and the angle is adjusted according to the change of light.

[0045] When the algae and fungi grow and reproduce more and affect the light of the algae and fungi inside, it is necessary to discharge the excess algae and fungi. The push rod 105 is pulled to move the algae and fungi push-pull plate 102 towards the direction close to the baffle 103. The algae and fungi push-pull plate 102 drives the excess algae and fungi at a higher position to the inside of the algae and fungi discharge pipe 101. The rotating handle 203 is held to rotate the rotating shaft 201 and the baffle 202, so that the rotating handle 203 and the baffle 206 are close to each other. At this time, the baffle 202 is pressed against the algae and fungi discharge pipe 101. The tube 101 is closed, and the baffle 103 is unscrewed to discharge the algae and fungi and a small amount of sewage inside the algae and fungi discharge pipe 101. The collected algae and fungi can be used for other sewage treatment or other uses, and the collected sewage can continue to be introduced into the sewage treatment chamber 1 for sewage treatment. The baffle 103 is tightened, and the baffle plate 202 is turned away from the area of ​​the algae and fungi discharge pipe 101. The push rod 105 is pushed to push the algae and fungi push-pull plate 102 until it is in contact with the inner wall of the sewage treatment chamber 1, and the sewage treatment can continue.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
