DETAILED DESCRIPTION

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the utility model provides a medical sewage treatment device, including a pretreatment tank 1, a partition 9 is provided in the middle position of the pretreatment tank 1, the partition 9 divides the inner cavity of the pretreatment tank 1 into an upper cache cavity and a lower pretreatment cavity, and a biological bacteria adding device 11 is provided on the side wall of the pretreatment cavity.

[0029] A drain outlet is provided on the partition 9, and a first electric valve 10 is provided on the drain outlet. An upper baffle ring 1201 and a lower baffle ring 1202 are arranged in an upper and lower interval in the pretreatment chamber. A first micro switch 14 is provided on the lower surface of the upper baffle ring 1201 and a second micro switch 15 is provided on the upper surface of the lower baffle ring 1202. A floating ring 13 is provided between the upper baffle ring 1201 and the lower baffle ring 1202.

[0030] A certain amount of biological bacteria is added through the biological bacteria addition port, and the sewage flows from the first electric valve 10 on the partition 9 into the pretreatment chamber. As the amount of sewage increases, the floating ring 13 floats upward. At the same time, the sewage decomposes the organic matter in the sewage into non-toxic inorganic matter under the action of biological bacteria. When the floating ring 13 hits the first micro switch 14, the electric control system controls the first electric valve 10 to close. At this time, the sewage flowing into the pretreatment tank 1 is stored in the buffer chamber. The sewage is preliminarily treated and settled in the pretreatment chamber. The control system controls the sewage to be pumped out. As the sewage decreases, the floating ring 13 sinks. After hitting the second micro switch 15, the electric control system controls to stop pumping sewage, and the first electric valve 10 opens. In this way, according to the sewage discharge volume, the start and stop of sewage treatment are controlled by the electric control system. When the amount of medical sewage generated in the hospital is small, the floating ring 13 will not trigger the first micro switch 14, thereby realizing the automatic control of the start and stop of sewage treatment according to the discharge volume of medical waste water.

[0031] The biological bacteria adding device 11 is controlled by an electric control system to discharge biological bacteria. After the sewage is pumped out, when the floating ring 13 hits the second solenoid valve 15, the electric control system controls the biological bacteria adding device 11 to add a quantitative amount of biological bacteria into the pretreatment chamber.

[0032] An ultraviolet lamp 4 is arranged on the side wall of the buffer cavity, and the sewage entering the pretreatment tank 1 is preliminarily disinfected under the action of the ultraviolet lamp 4 .

[0033] A solid waste filtering device is provided on the top of the pretreatment tank 1, and the solid waste filtering device includes a filter screen 2, a conveying auger 3 is horizontally provided on the upper end of the filter screen 2, a wastewater inlet 5 is provided on the upper side of the input end of the conveying auger 3, and a baffle 6 is hinged at the wastewater inlet 5. When no wastewater flows in, the baffle 6 is in a closed state to prevent the odor inside the equipment from overflowing.

[0034] The side of the pretreatment tank 1 is hingedly provided with a waste barrel packaging groove 8, in which a solid waste barrel 7 is placed. The upper opening of the solid waste barrel 7 is opposite to the output end of the conveying auger 3, and the solid waste filtered out by the filter screen 2 falls into the solid waste barrel 7 from the output end of the conveying auger 3.

[0035] A fixed handle is provided on the outside of the waste barrel packaging slot 8, and the fixed handle is fixed on the outer wall of the waste filtering device. When replacing the solid waste barrel 7, the fixed handle is loosened and the waste barrel packaging slot 8 is turned outward. Figure 2 As shown, the solid waste container 7 can be easily taken out.

[0036] The utility model further comprises a deep treatment tank 18 , which is connected to the pretreatment tank 1 through a sewage pipe. A water pump 16 is provided on the sewage pipe section, and the water pump 16 transports the sewage in the pretreatment cavity to the deep treatment tank 18 .

[0037] The deep treatment tank 18 is provided with a stirring device 21, which is driven by a driving motor 20. The deep treatment tank 18 is provided with a medicine box 19, which contains medicine.

[0038] An ozone generator 17 is provided on one side of the deep treatment tank 18 , and an air outlet pipe 23 is provided at the bottom of the deep treatment tank 18 . The air outlet pipe 23 is fixedly connected to the rotating shaft of the stirring device 21 , and the ozone generator 17 is connected to the air outlet pipe 23 via a rotary joint 22 .

[0039] The specific working principle of the utility model:

[0040] Medical sewage enters the solid waste filtering device from the wastewater inlet 5, and the sewage passes through the filter screen 2 and enters the pretreatment tank 1 at the lower end. The biological bacteria adding device 11 is controlled by the electronic control system to discharge a certain amount of biological bacteria; the sewage flows from the first electric valve 10 on the partition 9 into the pretreatment chamber. As the amount of sewage increases, the floating ring 13 floats upward. At the same time, the sewage decomposes the organic matter in the sewage into non-toxic inorganic matter under the action of biological bacteria. When the floating ring 13 hits the first micro switch 14, the electronic control system controls the first electric valve 10 to close. At this time, the sewage flowing into the pretreatment tank 1 is stored in the buffer chamber. The sewage is preliminarily treated and settled in the pretreatment chamber. The control system controls the water pump 16 to start, and the sewage is pumped out. As the sewage decreases, the floating ring 13 sinks. After hitting the second micro switch 15, the control system controls the water pump 16 to stop pumping sewage, and the first electric valve 10 opens, and the sewage continues to flow into the pretreatment chamber. When the amount of medical wastewater generated in the hospital is small, the floating ring 13 will not trigger the first micro switch 14, thereby realizing automatic control of the start and stop of the sewage treatment according to the discharge amount of the medical wastewater.

[0041] When the water pump 16 is started, the electronic control system controls the medicine box 19 to add medicine into the deep treatment tank 18, and the stirring device 21 starts stirring and the ozone generator 17 starts working; the sewage is deeply treated, and after the water pump 16 stops working, the electronic control system controls the second electric valve 24 at the bottom of the deep treatment tank 18 to open and discharge the sewage.
