Description

Technical Field

[0001] The invention relates to the field of sewage purification, and in particular to an environmentally friendly purification device for chemical sewage containing fluorine polymers. Background Art

[0002] The wastewater generated in chemical production contains a variety of pollutants, such as fluoride. Fluoride generally needs to go through neutralization, adjustment, coagulation, flocculation, precipitation, adsorption and other processes during the treatment process. There are many ways to purify chemical wastewater in the prior art. Among them, the method of purifying wastewater by utilizing the synergistic effect of the physiological functions of algae and bacteria has attracted widespread attention. The purification effect of bacteria and algae is first used to treat other organic pollutants in the wastewater, and the remaining fluoride and other pollutants that are difficult to be purified by bacteria and algae are treated separately, thereby saving the treatment cost of fluoride. For example, the Chinese patent with publication number: CN108892228B discloses a bacteria-algae composite biofilm wastewater treatment device, the light emitted by its fluorescent lamp provides illumination for the respiration of bacteria and algae, promotes their rapid growth and metabolism, and accelerates the purification of sewage. The cage realizes the dispersion and buffering effect of the airflow generated by aeration, avoids the generation of large airflow impact, ensures that the bacteria and algae on the biofilm fully purify the sewage, and effectively improves the sewage treatment efficiency.

[0003] If fluorescent lamps are used all the time to provide light to satisfy the photosynthesis of algae, a lot of electricity will be wasted and the cost of sewage treatment will be too high.

DETAILED DESCRIPTION

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Example 1 A fluorine-containing polymer chemical wastewater environmental protection purification device, such as Figure 1-Figure 7 As shown, it includes a fixing seat 1, a box body 2, a cover plate 3, a water inlet pipe 4, a water outlet pipe 5, a sewage pipe 7, a net cylinder 101, a cylinder 102 and an aeration pipe 103; the fixing seat 1 is fixedly connected to a box body 2 made of tempered glass; the box body 2 is connected to a water inlet pipe 4; the box body 2 is connected to a water outlet pipe 5; the box body 2 is connected to a sewage pipe 7, and the sewage pipe 7 is lower than the water inlet pipe 4 and the water outlet pipe 5; the box body 2 is detachably connected to the cover plate 3; the box body 2 is fixedly connected to the net cylinder 101, and the net cylinder 101 is detachably connected to the cover plate 3; the net cylinder 101 is connected to a cylinder 102 for inoculating biofilm; the inner side of the net cylinder 101 is fixedly connected to the aeration pipe 103; It also includes a light sensor 6, an electric guide rail Ⅰ104, a moving block Ⅰ105, a lamp tube 106, an electromagnet 107, a magnetic block 108 and a filter film 109; the box body 2 is provided with an annular groove 21; the cover plate 3 is fixedly connected to the light sensor 6; the cover plate 3 is bolted to the electric guide rail Ⅰ104; the electric guide rail Ⅰ104 is slidably connected to at least ten moving blocks Ⅰ105; each moving block Ⅰ105 is connected to a lamp tube 106 through a buckle, and the lamp tube 106 is located in the annular groove 21; each lamp tube 106 is fixedly connected to an electromagnet 107; the box body 2 is fixedly connected to a plurality of filter films 109, and the filter films 109 are located in the annular groove 21, and the position and number of the filter films 109 correspond to the lamp tube 106; each filter film 109 is fixedly connected to a magnetic block 108, and the magnetic block 108 and the electromagnet 107 are attracted to each other.

[0022] It also includes a focusing plate 1010; each lamp tube 106 is fixedly connected to two curved focusing plates 1010, and the focusing plates 1010 collect light emitted by the lamp tube 106 onto the biofilm of the cylinder 102 to improve the photosynthetic efficiency of the algae.

[0023] The spectral wavelengths of the light emitted by the lamp tube 106 are red light and blue light. Since red light and blue light are most beneficial to the growth of most algae, the spectral wavelengths of the light emitted by the lamp tube 106 are adjusted to red light and blue light to adapt to most algae and improve the adaptability of bacteria and algae.

[0024] When in use, first connect the external sewage pump to the water inlet pipe 4, connect the external sewage pump to the sewage pipe 7, connect the external clean water pipe to the water outlet pipe 5, and then connect the external air pump to the aeration pipe 103, manually open the cover plate 3, and set the cylinder 102 with the biofilm grown on the outside of the net cylinder 101, and the biofilm of the cylinder 102 is inoculated with bacteria and algae in advance. Then, put the cover plate 3 back, control the external sewage pump to transport sewage to the water inlet pipe 4, close the water outlet pipe 5, and then let the sewage enter the box body 2, the water level is flush with the upper surface of the cylinder 102, and when there is sunlight during the day, the sunlight shines through the tempered glass box body 2 onto the bacteria and algae on the cylinder 102, thereby killing the algae. Provide light, and control the start of the external air pump to pump air into the aeration pipe 103. The air coming out of the aeration pipe 103 passes through the mesh tube 101, and after the buffering and dispersion effect of the mesh tube 101, it flows to the biofilm on the cylinder 102 to improve the mass transfer of dissolved oxygen content in the sewage. At this time, the fungi consume oxygen through respiration to produce carbon dioxide, and the algae consume carbon dioxide in the sewage through photosynthesis to produce oxygen, forming a symbiotic relationship with the fungi, thereby promoting the growth of the fungi and algae, achieving full absorption and decomposition of nitrogen, phosphorus compounds and other organic matter in the sewage, and achieving efficient purification of the sewage.

[0025] The purified sewage is discharged through the outlet pipe 5, and then the sludge generated at the bottom of the box 2 is pumped away through the external sewage pump and the sewage pipe 7. Since the sewage pipe 7 is lower than the outlet pipe 5, the sludge will not enter the outlet pipe 5. In the above purification process, other organic pollutants in the sewage are first purified by the symbiotic purification system formed by bacteria and algae. The fluoride in the sewage that cannot be treated by bacteria and algae is treated separately in the subsequent purification process, which saves the treatment process and reduces the purification cost. It should be noted that the bacteria and algae inoculated in the cylinder 102 can be specific microorganisms or algae, which can effectively decompose or convert part of the fluoride ions in the wastewater through the metabolic activities of specific microorganisms or algae, which is more conducive to reducing the subsequent treatment cost.

[0026] When there is no sunlight at night, the lamp 106 is powered on, and the fluorescence emitted by the lamp 106 is irradiated through the box 2 onto the biofilm of the cylinder 102, providing light for the algae and ensuring the purification of sewage. When the sunlight is strong during the day, the lamp 106 is turned off, and the electromagnet 107 is powered on. The electromagnet 107 and the magnetic block 108 are mutually attracted by the magnetic force, and then the electric guide rail Ⅰ104 is controlled to make the moving block Ⅰ105 drive the lamp 106 to rotate, and then the lamp 106 makes the electromagnet 107 and the magnetic block 108 pull the filter film 109 which is initially in a folded state until the filter film 109 is in an unfolded state, as shown in FIG. Figure 6 As shown, the strong sunlight is filtered through the filter film 109 to reduce the intensity of the light entering the box 2, thereby preventing the excessive sunlight from causing damage to the algae and reducing the activity of the algae.

[0027] However, since the irradiation angle of sunlight changes with time, the light on one side of the box 2 is too strong, while the light on the other side is too weak, resulting in the algae in the weaker light area unable to carry out normal photosynthesis, thereby reducing the sewage treatment efficiency. Therefore, the direction of sunlight is detected by the light sensor 6, and then the light sensor 6 controls the electric guide rail Ⅰ104 to make the moving block Ⅰ105 drive the lamp tube 106 to rotate, so that multiple lamp tubes 106 are gathered on the weaker light area of ​​the box 2, and then the lamp tube 106 is energized, so that the multiple gathered lamp tubes 106 can irradiate the weaker light area on the box 2 together for supplementary light, so that the light irradiated on the box 2 is relatively uniform, thereby improving the photosynthesis efficiency of the algae and enhancing the purification effect. When the lamp tube 106 is rotating, the electromagnet 107 is not energized.

[0028] Example 2 On the basis of Example 2, Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, it also includes an electric guide rail II 201, a moving block II 202, a rectangular plate 203, a screen 204, a collecting plate 205, a connecting ring 206, a collecting tube 207 and a camera 208; the cover plate 3 is bolted to the electric guide rail II 201; the electric guide rail II 201 is slidably connected to two moving blocks II 202; each moving block II 202 is detachably connected to a rectangular plate 203, and the rectangular plate 203 is located in the box body 2, and the rectangular plate 203 is in contact with the inner wall of the box body 2; a screen 204 is fixedly connected to the upper side of each rectangular plate 203; a collecting plate 205 is fixedly connected to the upper side of each rectangular plate 203; the cover plate 3 is rotatably connected to the connecting ring 206; the connecting ring 206 is fixedly connected to two collecting tubes 207, and the collecting tubes 207 are located above the corresponding collecting plates 205; a number of cameras 208 are fixedly connected to the lower side of the cover plate 3, and the cameras 208 face the corresponding collecting plates 205.

[0029] Each collecting plate 205 is provided with an inclined portion 2051 .

[0030] Three screens 204 with staggered meshes are fixedly connected to the upper side of each rectangular plate 203, so as to reduce the amount of algae leaking from the screen 204, enhance the interception effect on the algae, and further improve the collection effect on bacteria and algae.

[0031] It also includes guide plates 209; each rectangular plate 203 is fixedly connected with a plurality of guide plates 209 which are arranged obliquely.

[0032] A filter screen 2011 is also included; the filter screen 2011 is fixedly connected to the box body 2, and the filter screen 2011 is located below the rectangular plate 203.

[0033] First, the external pump is connected to the collection pipe 207, the inclined part 2051 is located in the sewage, and the lower part of the screen 204 is located above the sewage. Since algae will bloom in the process of purifying pollutants in the sewage, a large amount of algae will float on the surface of the sewage, affecting the water quality of the sewage after purification and reducing the treatment efficiency of the purification system. Therefore, the electric guide rail II 201 is controlled to drive the moving block II 202, the rectangular plate 203 and the screen 204 to rotate counterclockwise from the perspective of looking down, and then the screen 204 rotates to The algae on the surface of the sewage are scraped and collected, and the collected algae fall onto the collecting plate 205. The inclined portion 2051 guides the sewage, and the amount of algae collected on the collecting plate 205 is observed through the camera 208. When there are more algae on the collecting plate 205, the external pump is controlled to start, and the algae on the collecting plate 205 are pumped away through the collecting pipe 207, and then the algae are collected to avoid algal blooms in the sewage. The moving block II 202 drives the collecting pipe 207 and the connecting ring 206 to rotate, and the connecting ring 206 rotates on the cover plate 3.

[0034] During the sewage treatment process, sludge will be attached to the biofilm of the cylinder 102 and the inner wall of the box body 2. The rectangular plate 203 drives the guide plate 209 to rotate when it rotates counterclockwise, and then the guide plate 209 guides the sewage upward, so that the impurities and algae suspended in the sewage float to the surface of the sewage, which is convenient for the screen 204 to collect. At the same time, the guide plate 209 guides the sewage to the outer area of ​​the cylinder 102, so that the sewage flushes the outer area of ​​the cylinder 102, reducing the amount of sludge attached to the biofilm of the cylinder 102. By utilizing the growth of bacteria and algae, the rectangular plate 203 contacts the inner wall of the box body 2 when rotating, and then the rectangular plate 203 scrapes off the sludge attached to the inner wall of the box body 2. The sludge passes through the filter screen 2011 and falls to the bottom of the box body 2. The filter screen 2011 blocks the settled sludge, reducing the degree of rising of the settled sludge caused by the rotation of the rectangular plate 203, which is beneficial to subsequent discharge.

[0035] Example 3 On the basis of Example 2, Figure 2 and Figure 7 As shown, it also includes a scraper ring 301, a connecting plate 302, a connecting frame 303 and a sealing ring 304; the net cylinder 101 passes through the cover plate 3; the scraper ring 301 is fixedly connected to the box body 2, and the inner diameter of the scraper ring 301 is the same as the outer diameter of the cylinder 102; the cover plate 3 is fixedly connected to two connecting plates 302, and the connecting plates 302 are detachably connected to the net cylinder 101; the box body 2 is fixedly connected to a connecting frame 303, and the connecting frame 303 is detachably connected to the net cylinder 101; the box body 2 is detachably connected to a sealing ring 304 for sewage seepage prevention, and the sealing ring 304 is in contact with the outer surface of the net cylinder 101.

[0036] The cross section of the scraper ring 301 is set in an eight-shaped shape, thereby directing the scraped old biofilm and bacteria and algae to the bottom of the box 2, avoiding the scraped old biofilm and bacteria and algae from remaining on the scraper ring 301, and improving the dropping efficiency of the old biofilm and bacteria and algae.

[0037] During normal sewage treatment, the connecting plate 302 and the connecting frame 303 fix the net cylinder 101 together to enhance the fixing effect of the net cylinder 101. When the biofilm on the cylinder 102 needs to be replaced, the connecting frame 303 is first removed, and then the sealing ring 304 is taken out. Then, the old cylinder 102 is manually pulled downward, and the cylinder 102 contacts the scraping ring 301 when it moves downward, and then the scraping ring 301 scrapes off the old biofilm and algae on the cylinder 102, and the scraped old biofilm and algae fall below the filter screen 2011. The bottom of the box body 2 is then reinstalled, the sealing ring 304 is reinstalled into the box body 2, and the connecting frame 303 is refixed to the lower side of the net cylinder 101. Next, the connecting plate 302 is removed, and the cylinder 102 with the new biofilm is downwardly sleeved on the net cylinder 101, and the new biofilm is inoculated with bacteria and algae until the cylinder 102 is completely sleeved on the net cylinder 101, and then the connecting plate 302 is refixed to the upper side of the net cylinder 101, so that the new cylinder 102 is sleeved on the net cylinder 101, which is convenient for replacing the biofilm.
