Description

Technical Field

[0001] This utility model relates to the field of phenol-containing wastewater treatment technology, and in particular to a device for treating phenol-containing wastewater based on biological enzyme catalysis. Background Technology

[0002] Phenol-containing wastewater mainly comes from petrochemical plants, resin plants, etc. Phenol is a raw material and intermediate in the production of paper, plastics, pharmaceutical synthesis and other industries. Phenol wastewater flows into rivers, causing serious pollution to the environment and posing a significant threat to people's health.

[0003] Bioenzymes are organic proteins with catalytic functions produced by living cells. Bioenzymes used in industrial wastewater treatment are catalytic proteins extracted from natural plants. When these catalytic proteins are added to a wastewater biological treatment system, they can bind to microorganisms, thereby enhancing the resistance of the microorganisms in the biological treatment system to toxins (especially salt resistance) and shock resistance; in addition, they can also catalyze the degradation of organic matter in wastewater that is difficult to biodegrade.

[0004] However, biological enzymes are prone to losing their activity due to significant changes in ambient temperature. Both high and low temperatures can reduce or eliminate enzyme activity. Traditional wastewater treatment devices cannot effectively control wastewater temperature and biological enzyme storage temperature. As biological enzymes are continuously fed, their activity is easily reduced, resulting in a significant decrease in wastewater treatment quality. Utility Model Content

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this invention are as follows: In the actual treatment of phenol-containing wastewater, a biological enzyme system can be established first. The wastewater is introduced into the treatment tank through the inlet, followed by the operation of a cooling water circulator. The circulator cools the water to a suitable temperature and then introduces it into the cooling chamber of the cooling tank through the inlet pipe. This allows the cooling water to flow into the additive mechanism, enabling temperature-controlled storage of the biological enzymes and their excipients stored there. Subsequently, the cooling water in the cooling chamber flows through the first inlet into the gap between the inner wall of the cooling tank and the outer wall of the treatment tank. The wastewater in the treatment tank is transferred to the cooling water via heat transfer. The cooled water, having absorbed heat, then enters the cooling water circulator through the outlet pipe for further cooling. This allows for better temperature control of the wastewater and biological enzymes. When further treatment is needed... When adding bio-enzymes and their excipients to wastewater, the addition mechanism can be operated to introduce the bio-enzymes and excipients into the treatment tank. Subsequently, through the action of the enzymes, the activity of the microbial community is quickly activated, thereby accelerating the overall biodegradation and decomposition process and gradually forming an enzyme system. After the enzyme system is gradually formed, in order to maintain its balance, it is necessary to continuously replenish the lost bio-enzymes and their excipients. The addition mechanism can be operated again to replenish the bio-enzymes and excipients into the wastewater. This allows for better temperature control of the bio-enzyme storage device in the wastewater treatment unit. During the temperature-controlled storage of the bio-enzymes, the wastewater temperature is also controlled, ensuring that the bio-enzymes, when added to the wastewater, exert their maximum effectiveness and improve the quality of wastewater treatment.

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 3 As shown, the present invention provides a device for treating phenol-containing wastewater based on bio-enzyme catalysis, comprising a treatment tank 23, an addition mechanism, and a temperature control mechanism. The temperature control mechanism is provided on the outside of the treatment tank 23, and the addition mechanism is connected to the temperature control mechanism. The treatment tank 23 has an inlet at the top and an outlet at the bottom.

[0026] The temperature control mechanism includes a cooling tank 8, a cooling box 13, a cooling water circulator 11, an inlet pipe 19, and an outlet pipe 26. The cooling tank 8 is sleeved on the outside of the processing tank 23 and connected to the processing tank 23. A gap is provided between the inner wall of the cooling tank 8 and the outer wall of the processing tank 23. A first liquid inlet is provided at the upper part of the cooling tank 8, and a first liquid outlet is provided at the lower part of the cooling tank 8. A second liquid inlet is provided on one side of the cooling box 13, and a second liquid outlet is provided on the other side of the cooling box 13. The cooling water circulator 11 has a third liquid outlet at its upper part and a third liquid inlet at its lower part. The second liquid outlet is connected to the first liquid inlet. The second liquid inlet is connected to the third liquid outlet through an inlet pipe 19. The first liquid outlet is connected to the third liquid inlet through an outlet pipe 26. The cooling tank 13 has a cooling chamber inside. One side of the adding mechanism is located inside the cooling chamber, and the other side of the adding mechanism is connected to the upper part of the processing tank 23.

[0027] The working principle of this utility model is as follows: In the actual treatment of phenol-containing wastewater, a biological enzyme system can be established first. The phenol-containing wastewater is introduced into the treatment tank 23 through the inlet. Then, the cooling water circulator 11 is run to cool the water to a suitable temperature. The water is then introduced into the cooling chamber of the cooling box 13 through the inlet pipe 19. When the cooling water flows into the addition mechanism, it can control the temperature of the biological enzymes and their excipients stored therein. Subsequently, the cooling water in the cooling chamber flows into the gap between the inner wall of the cooling tank 8 and the outer wall of the treatment tank 23 through the first inlet. The wastewater in the treatment tank 23 is transferred to the cooling water through heat transfer, and then absorbs heat. The cooling water enters the cooling water circulator 11 through the outlet pipe 26 for further cooling, thereby enabling better temperature control of the wastewater and bio-enzymes. When it is necessary to add bio-enzymes and their excipients to the wastewater, the adding mechanism can be operated to add the bio-enzymes and their excipients into the treatment tank 23. Subsequently, through the action of enzymes, the activity of the microbial community is brought into play as soon as possible, thereby accelerating the entire biodegradation and decomposition speed and gradually forming an enzyme system. After the bio-enzyme system is gradually formed, in order to maintain the balance of the enzyme system, it is necessary to continuously replenish the lost bio-enzymes and their excipients. The adding mechanism can be operated again to replenish the bio-enzymes and their excipients into the wastewater.

[0028] Furthermore, the adding mechanism includes a storage box 21, a hanging platform 20, and an extraction component. The storage box 21 is provided with the hanging platform 20 on its upper part, and the cooling box 13 is provided with a limiting platform adapted to the hanging platform 20 on its upper part. The storage box 21 is pressed onto the limiting platform by the hanging platform 20. The storage box 21 is located inside the cooling chamber, and the storage box 21 is connected to the upper part of the processing tank 23 by the extraction component.

[0029] As can be seen from the above description, it is beneficial to add biological enzymes and their excipients into the storage tank 21. Before the cooling water cools the wastewater, it first passes through the cooling tank 13. Then the biological enzymes in the storage tank 21 are better preserved at the temperature. Subsequently, the wastewater in the cooling tank 13 continues to flow into the cooling tank 8 to cool the wastewater. When it is necessary to add biological enzymes and excipients into the wastewater, the extraction component can be operated to add the biological enzymes and their excipients in the storage tank 21 into the wastewater for reaction.

[0030] Furthermore, the extraction assembly includes a material extraction tube 25, a material extraction component 16, and a feed tube 17. The top of the processing tank 23 is provided with an opening, and a cover 5 is detachably connected to the opening. The cover 5 is provided with a feed inlet. The top of the storage tank is provided with a discharge outlet. The material extraction tube 25 passes through the discharge outlet. One side of the material extraction tube 25 is located inside the storage tank 21. The other side of the material extraction tube 25 is connected to one end of the feed tube 17 through the material extraction component 16. The other end of the feed tube 17 is connected to the feed inlet.

[0031] As can be seen from the above description, when it is necessary to add biological enzymes and auxiliary materials to the wastewater, the pumping unit 16 can be operated so that the pumping unit 16 can draw the biological enzymes and auxiliary materials in the storage tank 21 into the feed pipe 17 through the feed pipe 25, and then put them into the wastewater in the treatment tank 23.

[0032] Furthermore, it also includes a stirring mechanism. The processing tank 23 is equipped with a stirring mechanism, which is connected to the cover 5. The stirring mechanism includes a rotation drive 3, a first gear 1, a second gear 6, a stirring shaft 18, and stirring paddles 24. The stirring shaft 18 is rotatably connected to the cover 5. A plurality of stirring paddles 24 are arranged around the lower part of the stirring shaft 18. The stirring paddles 24 are disposed inside the processing tank 23. The first gear 1 is sleeved on the upper part of the stirring shaft 18. The second gear 6 is rotatably connected to the cover 5. The first gear 1 and the second gear 6 mesh with each other. The rotation drive 3 is drivenly connected to the second gear 6.

[0033] As can be seen from the above description, it is beneficial for the biological enzymes and their excipients to mix better with the wastewater. The rotating drive 3 can be operated so that the rotating drive 3 drives the first gear 1 to rotate through the second gear 6, thereby causing the first gear 1 to drive the stirring paddle 24 to stir the wastewater through the stirring shaft 18, so that the biological enzymes can mix better with the wastewater.

[0034] Furthermore, it also includes a pH probe 2. The stirring shaft 18 has a mounting groove in the middle that is adapted to the pH probe 2. The pH probe 2 passes through the mounting groove and has a probe head on it. The probe head is located below the stirring shaft 18.

[0035] As can be seen from the above description, the pH probe 2 is able to monitor the pH of the wastewater in the treatment tank 23 in real time, so that when the pH fluctuates greatly, it can be adjusted in time by supplementing biological enzymes and auxiliary materials.

[0036] Furthermore, it also includes several aeration rods 22, and several aeration rods 22 are laid at the bottom of the treatment tank 23.

[0037] As can be seen from the above description, the operation of the aeration rod 22 can prevent the suspended matter in the pool from sinking, enhance the contact between organic matter and microorganisms and dissolved oxygen in the pool, and thus ensure that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0038] Furthermore, it also includes a PLCPLC controller 12, which is electrically connected to the adding mechanism and the temperature control mechanism respectively.

[0039] As can be seen from the above description, it is beneficial to adjust the parameters of the device for treating phenol-containing wastewater based on bio-enzyme catalysis through the PLC controller 12, and to make it more convenient for operators to operate the device. Example 1
