Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage biological treatment, in particular to a sewage biological treatment reaction device based on high-molecular dissolved peptides. BACKGROUND

[0002] The high-molecular dissolved peptides are decomposability, also synthetic, facultative, good, and have a variety of molecules of organisms, which are a mutually beneficial biological community.

[0003] In the dissolved peptide composition, the yeast cells are hypersuperoxide, which can effectively decompose superoxide anions, free radicals into harmless water and oxygen, and eliminate the toxic effects on the organism. In addition, they grow and metabolize to generate physiological active substances, help other microorganisms and plants to absorb nutrients, and enhance the activity of effective peptides. The dissolved peptides have strong ability to decompose complex organic matter containing nitrogen and nitrogen, and play an important role in converting the substances in the sewage into water and oxygen. Under the condition of micro-nutrition, the dissolved peptide molecules can also work normally, and under anaerobic conditions, they ferment lactose to produce lactic acid to form an acidic environment, effectively inhibit the reproduction of corrosive microorganisms, promote the growth of beneficial microorganisms, improve the microbial community structure, accelerate the rapid reproduction of dissolved peptide molecules in the sewage, and accelerate the decomposition of organic matter in the dissolved sewage, thereby generating a stable and complex microecosystem, inhibiting the growth of harmful microorganisms, and simultaneously dissolving the odor generated by sulfur, nitrogen and other odor substances. The dissolved peptides can effectively and significantly remove the odor gas emitted by hydrogen sulfide and nitrogen in the sewage, effectively dissolve feces and urine into peptides, amino acids and other substances required by plants, have high activity, strong adaptability, and can perform biodegradation activities under high osmotic pressure environment.

[0004] The existing biological sewage treatment device is mostly for static treatment, and the contact area between the microorganisms and the sewage is small, so the sewage cannot be decomposed and treated at a high rate. The sewage cannot be disturbed when it is in contact with the microorganisms, and the biological treatment effect is not ideal. Moreover, the existing sewage treatment mostly uses multi-stage sedimentation media such as filter screens in the sedimentation tank to perform sedimentation and filtration treatment on the sewage. The removal effect of the filter screens on small-particle organic matter and emulsified oil is poor, and the monitoring of the treated water after the subsequent sewage treatment is not timely enough.

[0005] Therefore, the sewage biological treatment reaction device based on high-molecular dissolved peptides is proposed to solve the above problems. SUMMARY

[0006] In view of the deficiencies of the prior art, the present application provides a sewage biological treatment reaction device based on high molecular dissolved peptides, which significantly improves the removal efficiency of organic pollutants and nutrients by providing abundant high molecular dissolved peptides and optimizing the microbial environment, and exhibits significant advantages in energy saving, environmental protection and operation cost, while comprehensively monitoring the sewage treatment results by using monitoring equipment, thereby meeting the demand for high efficiency and sustainable development of modern sewage treatment.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0030] Please refer to Figures 1-7 The sewage biological treatment reaction device based on the high-molecular dissolved peptide in the embodiment comprises a base 1; a support 2 is assembled on the top of the base 1; a mixing cylinder 3 is arranged on the support 2;

[0031] A sewage biological mixing assembly 4 is arranged in the mixing cylinder 3;

[0032] A sewage sedimentation tank 5 is arranged on one side of the base 1, and the sewage sedimentation tank 5 is a rectangular pool body and is provided with a sedimentation tank cover plate 51 on the top;

[0033] The lower end surface of the sedimentation tank cover plate 51 is provided in parallel with two groups of movement adjusting assemblies 10, and a bearing seat 11 is assembled between the two groups of movement adjusting assemblies 10. The lower end surface of the bearing seat 11 is assembled with a protection frame 12, and the lower end surface of the protection frame 12 is assembled with a push rod motor 131. The output end bottom of the push rod motor 131 is assembled with a sewage monitoring sensor 13.

[0034] The upper end surface of the base 1 is supported with a mounting seat 6, and the mounting seat 6 is supported with a filter cylinder 7. A plurality of activated carbon plates 71 are arranged in the filter cylinder 7, and a biological cotton net 72 is arranged between adjacent two activated carbon plates 71.

[0035] In the embodiment, when the sewage to be treated is poured into the filter cylinder 7, the grease and various organic matters mixed in the sewage in the filter cylinder 7 can be uniformly filtered through the movement cooperation of the activated carbon plates 71 and the biological cotton net 72 arranged in the filter cylinder 7. Compared with the traditional single filter plate filtering mode, the activated carbon plates 71 of the application can effectively remove organic matter in the sewage, and the biological cotton net 72 arranged can act as a biological filtration medium, further filtering and separating the sewage, thereby improving the treatment effect of the sewage treatment reaction device as a whole.

[0036] It should be noted that the biological cotton net 72 is a mature medium, which is a high-efficiency filtration and support material specially designed for sewage treatment and other biological engineering applications. It mainly serves as a growth substrate for microorganisms, promotes the formation and development of biofilm, and enhances the degradation capacity of pollutants. The biological cotton net 72 is usually made of corrosion-resistant and wear-resistant high molecular materials, has good water permeability and high specific surface area, and can play multiple functions in sewage treatment.

[0037] Further, the dissolved peptide substances can promote nitrification and denitrification and biological absorption of phosphorus, effectively reduce the content of ammonia nitrogen, total nitrogen and total phosphorus in the effluent, prevent water body eutrophication, and at the same time, the high molecular dissolved peptides can cooperate with the microorganisms in the biological cotton net 72, thereby promoting the microorganisms to utilize organic matter more efficiently, reducing the proliferation of the microorganisms, and thereby reducing the production amount of activated sludge.

[0038] Please refer to Figures 1-2In order to allow the wastewater after primary filtration to enter the wastewater sedimentation tank for sedimentation treatment, the bottom of the filter cylinder 7 in this embodiment is provided with an opening, and a filter pipe 8 is connected to the opening; the upper end of the base 1 supports the wastewater sedimentation tank 9, and a pump 91 is assembled on the outside of the wastewater sedimentation tank 9. The input end of the pump 91 is connected to a pipeline that extends through the wastewater sedimentation tank 9 and into its interior. One end of the filter pipe 8 is connected to the wastewater sedimentation tank 9; the output end of the pump 91 is connected to a conveying pipe 92, and the other end of the conveying pipe 92 extends into the interior of the mixing tank 3 and is connected to the mixing tank 3.

[0039] In this embodiment, during wastewater treatment, the connection between the filter pipe 8 and the wastewater sedimentation cylinder 9 allows the wastewater in the filter cylinder 7 to undergo preliminary filtration via the activated carbon plate 71 and the bio-cotton mesh 72, and then re-enter the wastewater sedimentation cylinder 9 for preliminary sedimentation treatment.

[0040] It should be noted that the connection between the conveying pipe 92 and the mixing cylinder 3, and the connection between the pump 91 and the conveying pipe 92, enable the pump 91 to transfer the sewage flowing into the sewage sedimentation cylinder 9 to the mixing cylinder 3, so as to carry out a second sewage treatment in the mixing cylinder 3.

[0041] Please see Figures 3-4 In order to efficiently mix the high molecular weight soluble peptides and sewage, thereby improving the effect of biological treatment, the sewage biological mixing component 4 in this embodiment includes a drive shaft 42 rotating inside the mixing cylinder 3. Several positioning shafts 43 are sleeved on the outside of the drive shaft 42, and stirring blades 44 are arranged around the outside of each positioning shaft 43. A water outlet valve 31 is provided at the bottom of the mixing cylinder 3. The output end of the water outlet valve 31 is connected to a water outlet pipe 32, and the other end of the water outlet pipe 32 is connected to the sewage sedimentation tank 5. The sewage biological mixing component 4 also includes a drive motor 41 located at the upper end of the mixing cylinder 3. The output end of the drive motor 41 passes through the mixing cylinder 3 and is connected to the drive shaft 42.

[0042] In this embodiment, when the user connects the drive motor 41 to the power supply, the drive motor 41 is rotated to the transmission shaft 42, allowing the transmission shaft 42 to rotate within the mixing cylinder 3. When the transmission shaft 42 rotates, the user pours the high molecular weight dissolving peptides for wastewater treatment into the mixing cylinder 3. Combined with the rotation of the positioning shaft 43 and the stirring blade 44, the wastewater can fully react with the high molecular weight dissolving peptides within the mixing cylinder 3, achieving further treatment of the wastewater.

[0043] Furthermore, when the products of sewage sedimentation remain in the sewage sedimentation tank 9, the user can clean the sewage sedimentation tank 9 after each sewage treatment to facilitate the next sewage reaction treatment. In a preferred embodiment, the sewage sedimentation tank 9 is provided with a cleaning hatch on its side.

[0044] It should be noted that the upper part of the mixing cylinder 3 is provided with a feeding port, which can be used for the user to add the polymer dissolved peptide.

[0045] Please refer to Figures 5-7 In order to monitor the treated sewage, so as to ensure that the sewage is completely treated, the two groups of mobile adjusting assemblies 10 in the embodiment each include a lead screw seat 101 arranged below the sedimentation tank cover plate 51, a lead screw 103 rotatably arranged in the lead screw seat 101, and a sliding block seat 104 arranged outside the lead screw 103. Two deep groove ball bearings 102 are assembled on the lead screw seat 101, and the two ends of the lead screw 103 are rotatably arranged between the two deep groove ball bearings 102. Two side rods 106 are further assembled on the two lead screw seats 101, and the two side rods 106 are arranged in parallel on the two sides of the lead screw 103 and penetrate through the sliding block seat 104. One end of each of the two lead screws 103 penetrates through the lead screw seat 101 adjacent thereto and extends to the outside of the lead screw seat 101 and is connected with a reciprocating motor 105. The output end of the reciprocating motor 105 is connected with one end of the lead screw 103.

[0046] In actual use, the reciprocating motor 105 is arranged to drive and control the lead screw 103. When the mobile adjusting assembly 10 is controlled, the user connects the motor controller to the two reciprocating motors 105, so that the two reciprocating motors 105 rotate at the same frequency. At this time, the lead screw 103 connected with the output end of the reciprocating motor 105 can rotate.

[0047] Further, the reciprocating motor 105 is provided with a motor synchronizer and a motor controller. The power connection mode of the reciprocating motor 105, the motor controller, and the motor synchronizer is prior art, and the control circuit can be realized by simple programming of those skilled in the art. It is common knowledge in the art, only its use is described, without modification, so the control mode and circuit connection are not described in detail.

[0048] It should be noted that the side rod 106 can laterally limit the sliding block seat 104. When the lead screw 103 rotates, it is connected to the bearing seat 11 and laterally limited by the two side rods 106, so that the sliding block seat 104 arranged can move linearly along the stroke range of the lead screw 103. At this time, the sliding block seat 104 can drive the protection frame 12 and the sewage monitoring sensor 13 to move linearly. The protection frame 12 can effectively prevent the direct collision and damage of external objects to the sewage monitoring sensor 13.

[0049] The working principle of the above embodiment is as follows:

[0050] First step, in the actual sewage treatment operation, the user pours the sewage to be treated into the filter cylinder 7, at this time the oil and various organic matter mixed in the sewage in the filter cylinder 7 can be uniformly filtered through the multi-stage filtering treatment between the active carbon plate 71 and the biological cotton net 72;

[0051] Second step: through the communication treatment between the filter pipe 8 and the sewage sedimentation cylinder 9, when the sewage in the filter cylinder 7 is preliminarily filtered through the active carbon plate 71 and the biological cotton net 72, it can enter the sewage sedimentation cylinder 9 again, at this time the user connects the power supply to the pump 91, and communicates between the conveying pipe 92 and the mixing cylinder 3, so that the pump 91 can transmit the sewage flowing into the sewage sedimentation cylinder 9 to the mixing cylinder 3, so as to carry out the second sewage treatment in the mixing cylinder 3;

[0052] Third step: when the sewage enters the mixing cylinder 3, the user can drive the sewage biological mixing assembly 4, and pour the high molecular dissolved peptide for sewage treatment into the mixing cylinder 3, and cooperate with the rotation of the positioning shaft 43 and the stirring blade 44, so that the sewage can fully react with the high molecular dissolved peptide in the mixing cylinder 3. The high molecular dissolved peptide provides sufficient carbon source to support the rapid reproduction and metabolic activity of microorganisms, significantly improves the degradation speed and efficiency of organic pollutants such as BOD and COD, so as to realize further treatment of the sewage;

[0053] Fourth step: the user can connect the external power supply to the push rod motor 131, so that the push rod motor 131 driving output end lifts or lowers the sewage monitoring sensor 13 until the sewage monitoring sensor 13 is close to the water surface and fully contacts with the sewage. Then the user can drive the moving adjusting assembly 10, so that the sewage monitoring sensor 13 moves in a straight line along the horizontal stroke range of the sedimentation tank cover plate 51, realizes the horizontal monitoring of the sewage monitoring sensor 13 to the sewage sedimentation tank 5, and through the cooperation of the moving adjusting assembly 10 and the push rod motor 131, the sewage monitoring sensor 13 can collect data at different positions and heights.

[0054] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
