[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1-3In this embodiment, a multi-stage purification treatment device for medical waste water includes a treatment box 1, wherein a disinfection zone 101, a mixing zone 102 and a filter box 104 are formed inside the treatment box 1, wherein the mixing zone 101 is conical, and an air duct 6 connected to an external air pump is provided on the upper surface of the treatment box 1, wherein the air duct 6 is located at the center of the treatment box 1, and the air duct 6 spans the mixing zone 102 and the disinfection zone 101, and a plurality of air ducts 7 are fixed on the outside of the air duct 6, which are equidistantly distributed and extend to the inside of the disinfection zone 101, and the number of the air ducts 7 is not less than seven, so The air duct 7 is T-shaped, and the cross-section of the air duct 7 is in contact with the inner bottom wall of the disinfection zone 101. Four aeration heads 8 are installed on the upper surface of the cross-section of the air duct 7 and are arranged at equal distances. An overflow pipe 4 is connected between the disinfection zone 101 and the mixing zone 102. The overflow pipe 4 is L-shaped, and the protruding end of the overflow pipe 4 faces upward. A serrated overflow groove 13 is installed at the top of the mixing zone 102. The tooth end of the overflow pipe 4 and the upward opening of the protruding end of the overflow pipe 4 are located on the same horizontal plane, and the serrated overflow groove 13 is connected to the filter box 104 through the overflow port 14.
[0016] In the above structure, wastewater is introduced through the left side of the treatment box, so that the wastewater is guided into the disinfection area, and chemicals are added into the disinfection area. The air pump is running, and the air guide pipe plays an air guide role. The air guide pipe plays a role in diverting the air pressure in the air guide pipe, and then it is exposed through the aeration head. Because the aeration heads are equidistantly distributed at the bottom of the disinfection area, the mixing of the chemicals and the wastewater can be improved, thereby improving the ability of the chemicals to disinfect the viruses in the wastewater. After the water rises to a certain height, it will be guided to the mixing area through the overflow pipe for precipitation until the water rises to a certain height, and then the treated water source is guided into the filter box through the cooperation of the serrated overflow groove and the overflow port, and then discharged after filtration, thereby improving the quality of medical water source treatment.
[0017] In order to improve the efficiency and quality of mixing, a medicine box 103 is formed in the treatment box 1, and the medicine box 103 is fixedly connected to the mixing area 102. The filter box 104 is located between the medicine box 103 and the disinfection area 101, and a medicine guide pump 9 connected to the medicine box 103 is installed on the frame of the treatment box 1. The outlet pipe of the medicine guide pump 9 is fixed with a U-shaped tube 10 located on the top edge of the disinfection area 101, and a plurality of dosing heads 11 arranged and distributed at equal distances are installed on the U-shaped tube 10. When dosing is required, start the medicine guide pump 9, and the medicine is guided by the U-shaped tube and then exported through the dosing head, so that the dosing position can be dispersed, so that in cooperation with the effect of aeration, the mixing efficiency and quality of the medicine and wastewater can be improved.
[0018] In order to prevent wastewater from splashing out, a support plate 2 is fixed on the top of the treatment box 1, a sleeve 3 extending into the mixing zone 102 is fixed on the bottom of the support plate 2, the sleeve 3 extends to the middle section of the mixing zone 102, and one end of the overflow pipe 4 extends to the inside of the sleeve 3. When the water depth in the disinfection zone reaches a certain height, the overflow pipe will guide the water source into the mixing zone, so under the action of the sleeve, the introduced wastewater can be prevented from splashing and the splashing can be prevented from affecting the external environment.
[0019] In order to improve the quality of wastewater treatment, a branch pipe 12 passing through the sleeve 3 and extending to the bottom of the mixing zone 102 is fixed on the outside of the air guide pipe 6, a valve is installed on the outside of the branch pipe 12, the bottom end of the branch pipe 12 is an arc-shaped tilted end, and a drug guide pipe 5 connected to an external drug guide device is fixed on the top of the treatment box 1, and the bottom end of the drug guide pipe 5 is located above the arc-shaped tilted end of the branch pipe 12. Under the action of the sleeve, the drug guide pipe can be prevented from splashing when guiding the drug. At the same time, because the branch pipe is connected to the air guide pipe, the branch pipe can also achieve the effect of aeration, so that the impurities in the wastewater are fully mixed with the medicine, and then the valve is closed to make the mixing zone still until the impurities are precipitated at the bottom of the mixing zone, thereby improving the quality of wastewater treatment.
[0020] The working principle of the above embodiment is:
[0021] By introducing wastewater into the disinfection area, and then running the air pump and the drug guide pump at the same time, the drug guide pump distributes the medicine in the medicine box to the top edge of the disinfection area through the U-shaped pipe, and then disperses and adds medicine through the dosing head. At the same time, the air pump cooperates with multiple air guide pipes and branch pipes to guide air, and completes the aeration treatment in the disinfection area through the aeration head. Therefore, the wastewater and the medicine can be fully mixed to complete the disinfection. After the water source rises to a certain height, under the action of the overflow pipe, the disinfected wastewater is guided to the mixing area through the sleeve, and then the drug guide pipe is added to the mixing area again. Another kind of agent, under the action of the sleeve, can prevent wastewater and agents from splashing, and then open the valve on the branch pipe to connect the branch pipe with the air duct. Therefore, under the action of the branch pipe, the wastewater and the agent in the mixing zone can be fully mixed. After the mixing is completed, the branch pipe is closed to make the mixing zone still until the water depth reaches the sawtooth overflow groove and overflows. It then flows into the filter box through the overflow port and is discharged after filtration. Therefore, the quality of wastewater can be improved through multi-stage treatment, so after discharge, it can avoid affecting the environment.
