Description

Technical Field

[0001] The utility model belongs to the technical field of printing and dyeing wastewater treatment, and specifically relates to printing and dyeing wastewater treatment equipment. Background Art

[0002] Printing and dyeing wastewater treatment refers to the treatment of wastewater generated in the printing and dyeing industry to reduce pollution to the environment and damage to the ecosystem. The characteristics of printing and dyeing industrial wastewater include high concentrations of organic matter, a large amount of pigments, fluctuations in pH, etc. At present, many printing and dyeing wastewater treatments will adopt the form of carbon water to neutralize wastewater, and remove organic matter, pigments and other pollutants in wastewater through adsorption and neutralization. Activated carbon can effectively adsorb organic matter and pigment molecules in wastewater, and can also adsorb substances such as ammonia and metal ions, and play a neutralizing role, which helps to adjust the pH value of wastewater.

[0003] Many existing methods for treating printing and dyeing wastewater use large-scale water storage tanks and sedimentation tanks. Chemicals are added to the wastewater during its flow and mixed uniformly in the water storage tank. Although the treatment effect can be achieved, this treatment method is relatively inefficient. Since the method of adding chemicals first and then mixing is adopted, the chemicals cannot be fully mixed with the wastewater during transportation, which can easily reduce the characteristics of the chemicals. As a result, when monitoring the treated wastewater later, it is often necessary to increase the dosage of the chemicals to achieve the treatment effect, thereby increasing the cost investment.

[0004] Therefore, a printing and dyeing wastewater treatment equipment is designed to change the above-mentioned technical defects. Utility Model Content

DETAILED DESCRIPTION

[0025] This specific embodiment is a printing and dyeing wastewater treatment equipment, and its structural schematic diagram is as follows Figure 1-Figure 6 As shown, it includes a water reservoir 1, a first mixing tank 2 and a second mixing tank 3. A wastewater pipe 4 is arranged on the water reservoir 1. A mounting plate 5 is fixedly connected to the right side walls of the water reservoir 1 and the first mixing tank 2 near the top surface. A first pump 6 is installed on the mounting plate 5. Two delivery pipes 7 are fixedly connected to the side wall of the first pump 6. The water inlet ends of the delivery pipes 7 are respectively connected to the water reservoir 1 and the first mixing tank 2, and the water outlet ends of the delivery pipes 7 are respectively connected to the first mixing tank 2 and the second mixing tank 3. Mixing components are arranged in the first mixing tank 2 and the second mixing tank 3, and a filling component is arranged on the left side wall of the first mixing tank 2.

[0026] The capacity of the water reservoir 1 is larger than that of the first mixing pool 2 and the second mixing pool 3. The water reservoir 1 is equivalent to a wastewater collection pool for diverting wastewater to multiple treatment pools. In some cases, the amount of wastewater generated is greater than the amount of wastewater treated, so the capacity of the water reservoir 1 must be ensured. The number of the first mixing pool 2 and the second mixing pool 3 can be set to multiple, so as to facilitate synchronous wastewater treatment.

[0027] like Figure 1-Figure 4 As shown, the mixing assembly includes an air inlet pipe 13, and two branch pipes 14 are fixedly connected to the side wall of the air inlet pipe 13. The branch pipes 14 extend to the first mixing pool 2 and the second mixing pool 3 respectively. The side walls of the branch pipes 14 are fixedly connected to a number of evenly distributed outlet pipes 15; the outlet pipes 15 are all bent in the clockwise direction.

[0028] Among them, the air inlet pipe 13 needs to be connected to the external air supply equipment, and the external air supply equipment can be in the form of an air pump, etc. The air flow is diverted to the diversion pipe 14 through the air inlet pipe 13, and combined with the bending form of the air outlet pipe 15, it can drive the wastewater to be aerated and rotated, thereby accelerating the flow rate of the wastewater.

[0029] A medicine tube 16 is disposed in each of the shunt tubes 14 . One end of the medicine tube 16 passes through the air inlet pipe 13 . A plurality of nozzles 17 are fixedly connected to the side wall of the medicine tube 16 . The nozzles 17 pass through the shunt tube 14 .

[0030] Specifically, the equipment used for adding the reagents can adopt the reagent adding equipment used in wastewater treatment in the prior art; and the reagents added mainly include PAC and PAM;

[0031] PAC is mainly used as a flocculant to form aluminum hydroxide flocs in water, which can absorb suspended matter, colloidal substances and particulate matter in the water and make them condense into larger agglomerates, which is convenient for subsequent sedimentation and filtration treatment;

[0032] PAM is usually used as an auxiliary agent for flocculants, which can enhance the flocculation performance of flocculants and promote the formation and sedimentation rate of flocs.

[0033] like Figure 6 As shown, a one-way valve 18 is fixedly installed in each of the reagent pipes 16. By providing the one-way valve 18, it is possible to prevent the pressure in the reagent pipe 16 from decreasing when no reagent is added, and to prevent waste water from entering the reagent pipe 16 when flowing.

[0034] like Figure 1 and Figure 5 As shown, the filling assembly includes a charcoal water tank 8 fixedly connected to the side wall of the first mixing tank 2, a filling pipe 9 fixedly connected to the top surface of the charcoal water tank 8, a second pump 10 fixedly installed on the top surface of the charcoal water tank 8, and two guide pipes 11 fixedly connected to the side wall of the second pump 10, which are respectively connected to the charcoal water tank 8 and the left delivery pipe 7. A valve 12 is installed on the side wall of the guide pipe 11.

[0035] Specifically, the carbon water tank 8 mainly contains pre-mixed activated carbon water. By using the carbon water neutralization method to treat the printing and dyeing wastewater, harmful substances can be effectively removed, water quality can be improved, and pollution to the environment can be reduced. This method can not only be used to treat organic matter and pigments in wastewater, but also effectively remove odors and improve the appearance of wastewater. At the same time, the activated carbon treatment method is relatively simple and easy to implement, and is one of the commonly used wastewater treatment technologies.

[0036] Working principle: First, the wastewater generated by printing and dyeing is discharged into the water storage tank 1 through the wastewater pipe 4, and then the first pump 6 on the left is started. The first pump 6 transports the wastewater in the water storage tank 1 to the first mixing tank 2 through the delivery pipe 7. At the same time, an air flow is injected into the air inlet pipe 13 by an external device, and PAC agent is injected into the agent pipe 16 by a dosing device. The agent flows out through the nozzle 17, and the inclined state of the air outlet pipe 15 is used to make the air flow drive the wastewater to rotate clockwise, thereby increasing the mixing rate with the agent.

[0037] At the same time, the valve 12 is opened according to the requirements of the printing and dyeing wastewater treatment, and the second pump 10 is started. The second pump 10 injects carbon water into the left delivery pipe 7 to neutralize the wastewater.

[0038] When the wastewater in the first mixing tank 2 is mixed, the first pump 6 on the right is started to transport the wastewater in the first mixing tank 2 to the second mixing tank 3. After the flocculant is added through the chemical pipe 16, it is fully mixed and then discharged to precipitate the organic matter and impurities in the wastewater, which are then discharged after filtration.

[0039] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation scheme of the utility model. In addition, the utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the utility model.
