DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides an assembled aerobic and anaerobic immobilized microbial sewage treatment device, which includes: a fixing unit 100 and a pretreatment unit 200.

[0031] The fixed unit 100 includes a fixed steel frame 101, an aerobic reaction zone 102 arranged on the fixed steel frame 101, an anaerobic reaction zone 103 arranged on the fixed steel frame 101, and a condensation and sewage discharge zone 104 arranged on one side of the fixed steel frame 101, and the aerobic reaction zone 102 is connected with the anaerobic reaction zone 103 and the condensation and sewage discharge zone 104. When the sewage is treated, the sewage is transported to the inside of the pretreatment unit 200, and the pretreatment unit 200 performs pretreatment, performs preliminary filtration, interception, and precipitation on the sewage to ensure that the pretreatment of the sewage is optimal, and the pretreated sewage enters the aerobic reaction zone 102 for aerobic reaction to ensure that the sewage in the aerobic reaction zone 102 is under aerobic conditions, and aerobic microorganisms decompose organic matter. The wastewater is aerobically treated and then transported to the anaerobic reaction zone 103 to undergo anaerobically treatment. The anaerobic reaction zone 103 is ensured to be in an anaerobic condition. The anaerobic microorganisms decompose the organic matter into methane and carbon dioxide, which are then recycled. Finally, the wastewater after the reaction is completed is transported to the condensation and drainage zone 104. The wastewater in the condensation and drainage zone 104 undergoes a condensation reaction through physical or chemical methods. The microorganisms are fixed on a carrier, such as a filler in a biofilm reactor. This helps to maintain the concentration of the microorganisms in the reactor and improve the treatment efficiency, so that the suspended solids and some soluble pollutants in the wastewater can be effectively removed. Finally, the wastewater is discharged in compliance with the standards. The pretreatment unit 200 includes a tank assembly 201 disposed on one side of the fixed steel frame 101, a filter assembly 202 disposed inside the tank assembly 201, a cleaning assembly 203 disposed on the filter assembly 202, and a conveying assembly 204 disposed on one side of the tank assembly 201. When the sewage is preliminarily pretreated, the sewage is conveyed to the inside of the tank assembly 201, and the sewage is preliminarily filtered by the filter assembly 202 inside the tank assembly 201 to intercept large impurities, and the preliminarily filtered sewage is flushed into the filter assembly 202. The impact force of the sewage causes the cleaning assembly 203 to start rotating, and the filter assembly 202 and the cleaning assembly 203 begin to cooperate to filter the sewage, and the outer wall of the filter assembly 202 and the cleaning assembly 203 are used to filter the sewage. The differentiated setting of the caliber of the filter holes at the bottom prevents large particles of sand and soil in the sewage from flowing out from the holes on the outer wall of the filter component 202, thereby causing the large particles of sand and soil in the sewage to be intercepted inside the filter component 202. At the same time, through the rotation of the cleaning component 203, not only can the sewage inside the filter component 202 be disturbed to accelerate the flow rate of the sewage, but also the impurity molecules in the sewage are affected by the centrifugal force to achieve separation from the water molecules. The pretreated sewage is transported to the next process through the conveying component 204, and the conveying component 204 can disturb the passing sewage, so that the flow rate of the sewage is accelerated, and impurities in the sewage cannot adhere to the inner wall of the pipe, thereby preventing impurities in the sewage from adhering to the inner wall of the pipe and causing pipe blockage.

[0032] Furthermore, the tank assembly 201 includes a tank body 201a arranged on one side of the fixed steel frame 101, a water inlet pipe 201b arranged on the top of the tank body 201a, a sewage pipe 201c arranged at the bottom of the tank body 201a, and a support column 201d arranged at the bottom of the tank body 201a. When sewage is transported to the inside of the tank assembly 201, the sewage is transported through the water inlet pipe 201b, so that the sewage can be transported to the inside of the tank body 201a for treatment. At the same time, the impurities collected at the bottom of the filter assembly 202 can be uniformly cleaned through the sewage pipe 201c, and the support column 201d stabilizes the device as a whole.

[0033] During use, when sewage is treated, the sewage is transported to the pretreatment unit 200, and the pretreatment unit 200 performs pretreatment, performs preliminary filtration, interception, and sedimentation on the sewage to ensure that the pretreatment of the sewage is optimal. The pretreated sewage enters the aerobic reaction zone 102 for aerobic reaction, ensuring that the sewage in the aerobic reaction zone 102 is under aerobic conditions, and aerobic microorganisms decompose organic matter and convert it into carbon dioxide and water, while releasing energy for discharge. The aerobic treated sewage is then transported to the anaerobic reaction zone 103, so that the sewage is anaerobically treated, ensuring that the anaerobic reaction zone 103 is under anaerobic conditions, and anaerobic microorganisms decompose organic matter into methane and carbon dioxide, which are then recycled. Finally, the sewage after the reaction is completed is transported to the coagulation and discharge area 104. The sewage in the coagulation and discharge area 104 undergoes a coagulation reaction through physical or chemical methods, and the microorganisms are fixed on a carrier, such as the filler in a biofilm reactor. This helps to maintain the concentration of the microorganisms in the reactor and improve the treatment efficiency, so that the suspended solids and some soluble pollutants in the sewage can be effectively removed. Finally, the sewage is discharged in compliance with the standards, and the pretreated sewage is transported to the next process for treatment through the conveying component 204. The conveying component 204 can turb the passing sewage, so that the flow rate of the sewage is accelerated, and the impurities in the sewage cannot contact the inner wall of the pipe, so as to prevent the impurities in the sewage from sticking to the inner wall of the pipe and causing the pipe to be blocked.

[0034] The sewage is transported to the pretreatment unit 200, and pretreated by the pretreatment unit 200, and the sewage is preliminarily filtered, intercepted, and precipitated to ensure that the filtration of the sewage is optimized. The pretreated sewage enters the aerobic reaction zone 102 for aerobic reaction, ensuring that the sewage in the aerobic reaction zone 102 is under aerobic conditions, and aerobic microorganisms decompose organic matter and convert it into carbon dioxide and water, while releasing energy for discharge. The aerobic-treated sewage is then transported to the anaerobic reaction zone 103, so that the sewage is anaerobically treated, ensuring that the anaerobic reaction zone 103 is under anaerobic conditions, and anaerobic microorganisms decompose organic matter into methane and carbon dioxide, and then recycle them. Finally, the sewage after the reaction is completed is transported to the condensation and drainage zone 104, and the condensation and drainage zone 104 allows the sewage inside to be fixed on a carrier by physical or chemical methods, such as the filler in the biofilm reactor, which helps to maintain the concentration of microorganisms in the reactor and improve the treatment efficiency, so that the suspended solids and some soluble pollutants in the sewage can be effectively removed, so that the sewage can be fully treated to meet the discharge standard.

[0035] Example 2, reference Figure 1 - Figure 8, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the filter assembly 202 includes a concave filter plate 202a arranged inside the tank body 201a, a filter barrel 202b arranged at the bottom of the concave filter plate 202a, and a collecting member 202c arranged at the bottom of the filter barrel 202b, and the collecting member 202c is connected to the sewage pipe 201c. When performing preliminary filtration, sewage enters the tank body 201a through the water inlet pipe 201b, and is preliminarily filtered by the concave filter plate 202a to filter and intercept large impurities in the sewage. The intercepted sewage is filtered by the concave filter plate 202a and flows into the filter barrel 202b, impacting the sewage. The sewage impacts the cleaning component 203 at the bottom of the concave filter plate 202a, causing the cleaning component 203 to start rotating and cooperate with the filter barrel 202b to filter the sewage. The sewage impacts the cleaning component 203, and the cleaning component 203 starts to disturb the sewage, so that the sewage hits the inner wall of the filter barrel 202b under the influence of centrifugal force, so that large particles of sand and soil are all intercepted and filtered inside the filter barrel 202b. At the same time, because the filter holes on the inner wall of the filter barrel 202b are smaller than the filter holes at the bottom of the filter barrel 202b, the sand and soil are all intercepted at the bottom of the filter barrel 202b, and the sand and soil are settled at the bottom of the filter barrel 202b, and finally enter the inside of the collecting piece 202c, which is convenient for the staff to collect.

[0036] Compared with Example 1, further, a transmission rod 202d is rotatably provided at the bottom of the concave filter plate 202a, and a reciprocating screw groove 202e is provided on the outer diameter of the transmission rod 202d, and the reciprocating screw groove 202e is rotatably connected to the cleaning component 203, and the diameter of the filter hole on the outer wall of the filter barrel 202b is smaller than the diameter of the filter hole at the bottom of the filter barrel 202b, and a propeller blade 202f is provided on the top of the outer diameter of the transmission rod 202d. When the sewage enters the interior of the filter barrel 202b, the sewage filtered by the concave filter plate 202a is flushed. At the same time, because the surface of the concave filter plate 202a is provided with a concave inclination, the direction in which the sewage filtered by the surface of the concave filter plate 202a impacts the propeller blade 202f changes, and the sewage always impacts toward one side of the transmission rod 202d, thereby driving the transmission rod 202d to rotate, and the cleaning component 203 begins to rotate and move along the outer diameter of the transmission rod 202d, so that the sewage inside the filter barrel 202b is disturbed, thereby realizing the separation of water molecules and impurity molecules.

[0037] Preferably, the cleaning assembly 203 includes a rotating ring 203a arranged on the reciprocating screw groove 202e, a connecting ring 203b arranged on the outer diameter of the rotating ring 203a, a supporting rod 203c arranged on the outer diameter of the connecting ring 203b, a return spring 203e slidably arranged inside the supporting rod 203c, a buffer block 203d arranged at the other end of the return spring 203e, and a cleaning ring 203f arranged at the other end of the buffer block 203d. A moving member 203a-1 is arranged inside the rotating ring 203a, and the moving member 203a-1 is slidably connected to the reciprocating screw groove 202e. When the propeller blade 202f rotates, the moving member 203a-1 also starts to rotate and rise along the reciprocating screw groove 202e due to the rotation of the transmission rod 202d. At the same time, the rotating ring 203a and the connecting ring 203b also rotate with the supporting rod 203c and the cleaning ring 203f. And because the reciprocating screw groove 202e on the transmission rod 202d intersects end to end, the movable part 203a-1 can be made to reciprocate and rotate up and down, and the cleaning ring 203f rotates inside the filter barrel 202b, causing the sewage to generate a vortex. The sewage begins to impact the inner wall of the filter barrel 202b under the influence of centrifugal force, and the sewage that has been preliminarily filtered is filtered again through the inner wall of the filter barrel 202b to prevent large particles of sand in the sewage from affecting subsequent treatment. The cleaning ring 203f can also sweep the inner wall of the filter barrel 202b during rotation, so that all the sand and soil attached to the inner wall of the filter barrel 202b can fall to the bottom of the filter barrel 202b, and finally fall into the collecting part 202c for unified collection and treatment, ensuring that there is no impurity adhering to the inner wall of the filter barrel 202b, thereby increasing the service life of the filter barrel 202b and ensuring the stability of the filtering ability of the filter barrel 202b.

[0038] During use, when performing preliminary filtration, sewage enters the tank body 201a through the water inlet pipe 201b, and is initially filtered by the concave filter plate 202a to filter and intercept large impurities in the sewage. The intercepted sewage passes through the concave filter plate 202a and flows into the filter barrel 202b. The sewage that is impacted impacts the cleaning component 203 at the bottom of the concave filter plate 202a, causing the cleaning component 203 to start rotating to cooperate with the filter barrel 202b to filter the sewage. The impact cleaning component 203 starts to disturb the sewage, so that the sewage hits the inner wall of the filter barrel 202b under the influence of centrifugal force, so that large particles of sand and soil are all intercepted and filtered inside the filter barrel 202b. At the same time, because the filter holes on the inner wall of the filter barrel 202b are smaller than the filter holes at the bottom of the filter barrel 202b, the sand and soil are all intercepted at the bottom of the filter barrel 202b. The sand and soil are settled at the bottom of the filter barrel 202b and finally enter the collection piece 202c, which is convenient for the staff to collect.

[0039] When the sewage enters the filter barrel 202b, the sewage filtered by the concave filter plate 202a rushes into the filter barrel 202b. At the same time, because the surface of the concave filter plate 202a is provided with a concave inclination, the direction in which the sewage filtered by the surface of the concave filter plate 202a impacts the propeller blade 202f changes, and the sewage always impacts one side of the transmission rod 202d, thereby driving the transmission rod 202d to rotate, and the cleaning component 203 begins to rotate and move along the outer diameter of the transmission rod 202d, so that the sewage inside the filter barrel 202b is disturbed, thereby realizing the separation of water molecules and impurity molecules.

[0040] The reciprocating screw groove 202e on the transmission rod 202d intersects end to end, so the movable part 203a-1 can be rotated up and down reciprocatingly, and the cleaning ring 203f rotates inside the filter barrel 202b, so that the sewage generates a vortex, and the sewage begins to impact the inner wall of the filter barrel 202b, and the sewage that has been preliminarily filtered is filtered again through the inner wall of the filter barrel 202b to prevent large particles of sand in the sewage from affecting subsequent treatment, and the cleaning ring 203f can also sweep the inner wall of the filter barrel 202b during rotation, so that all the sand and soil attached to the inner wall of the filter barrel 202b can fall to the bottom of the filter barrel 202b, and finally fall into the collecting part 202c for unified collection and treatment, ensuring that there is no impurity adhering to the inner wall of the filter barrel 202b, which affects the sewage filtration, thereby completing the pretreatment of the sewage, making it filtered completely, and continuing the subsequent treatment.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3, reference Figure 1 - Fig.10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the conveying assembly 204 includes a conveying pipe 204a arranged on one side of the tank body 201a, a guide block 204c arranged inside the conveying pipe 204a, and a propeller blade 204d rotatably arranged inside the conveying pipe 204a. After the pretreatment of the sewage is completed, the sewage reaches the active adsorption layer 204b, and the small molecular impurities contained in the sewage are adsorbed by the active adsorption layer 204b. Then the sewage enters the conveying pipe 204a. The guide block 204c inside the conveying pipe 204a can change the flow direction of the sewage and concentrate it all, so that the sewage can impact the propeller blade 204d. 204d, so that the propeller 204d can rotate inside the delivery pipe 204a, and rotate with the sewage inside the delivery pipe 204a, so as to speed up the flow rate of the sewage inside the delivery pipe 204a, and by speeding up the flow rate of the sewage, it is prevented that the sticky impurities in the sewage adhere to the inner wall of the delivery pipe 204a, causing the delivery pipe 204a to be blocked, affecting the transportation of the sewage, and the delivery component 204 is provided in the sewage delivery section that completes the pretreatment and the aerobic and oxygen delivery section, which can effectively prevent the sewage from adhering to the inner wall of the pipe during the transportation process, causing the impurities in the sewage to adhere to the pipe, causing the pipe to be blocked, and affecting the sewage transportation.

[0043] Compared with Example 2, further, an active adsorption layer 204b is provided on one side of the delivery pipe 204a, and the active adsorption layer 204b is connected to the tank body 201a. The active adsorption layer 204b adsorbs small molecule impurities and performs the final interception step to prevent small molecule impurities from being missed, and ensures pretreatment filtration to prevent insufficient impurity treatment inside the sewage from affecting subsequent reactions.

[0044] During use, after the pretreatment of the sewage is completed, the sewage reaches the active adsorption layer 204b, and the small molecular impurities contained in the sewage are adsorbed by the active adsorption layer 204b, and then the sewage enters the inside of the delivery pipe 204a. The guide block 204c inside the delivery pipe 204a can change the flow direction of the sewage and concentrate it all, so that the sewage can impact the propeller 204d, so that the propeller 204d can rotate inside the delivery pipe 204a, and rotate with the sewage inside the delivery pipe 204a, thereby accelerating the flow speed of the sewage inside the delivery pipe 204a, and by accelerating the flow speed of the sewage, preventing the sewage from The sticky impurities carried in the sewage adhere to the inner wall of the delivery pipe 204a, causing the delivery pipe 204a to be blocked, affecting the delivery of sewage, and a delivery component 204 is provided in the sewage delivery section that completes the pretreatment and the aerobic and oxygen delivery section, which can effectively prevent the sewage from adhering to the inner wall of the pipe during the transportation process, causing the impurities in the sewage to adhere to the pipe, causing the pipe to be blocked and affecting the sewage transportation. The active adsorption layer 204b adsorbs small molecular impurities and performs the last step of interception to prevent small molecular impurities from being missed, and ensures the pretreatment filtration to prevent the impurities in the sewage from being insufficiently treated and affecting the subsequent reactions.

[0045] The remaining structure is the same as that of Example 2.
