Embodiment 1

[0021] Example 1, such as figure 1 As shown, the present invention provides an ozone disinfection device for medical wastewater. The ozone generator (1) is connected to the side port of the jet pump (13) through the pipeline P1, and the lower port of the jet pump (13) is connected to the circulation tank (5) through the pipeline. P7 connection, the pipeline P7 is inserted from the upper part of the circulation tank (5) to the bottom of the circulation tank (5) and connected to the liquid distributor (7), the circulation tank (5) is connected to the centrifugal pump (9) through the pipeline P3, and the centrifugal pump (9 ) is connected to the upper port of the jet pump (13) through the pipeline P4, the liquid phase ozone detector (6) is installed on the lower side of the circulation tank (5), the pipeline P9 is connected to the upper side port of the circulation tank (5), and the pipeline P9 The other end is connected to the discharge pool, one end of the pipeline P5 is connec...

Embodiment 2

[0028] Embodiment 2, the present invention provides a kind of medical waste water ozone disinfection method, utilizes the disinfection device described in embodiment 1 to carry out the technological process of medical waste water disinfection specifically as follows:

[0029] S1, inject waste water into the circulation tank (5), the liquid level reaches 200mm below the upper side port of the circulation tank (5), and the waste water flows through the circulation tank (5), pipeline P3, pipeline P4, under the action of the centrifugal pump (9). A circulation is formed between the jet pump (13) and the pipeline P7;

[0030] S2, turn on the ozone generator (1), the ozone is sucked into the jet pump (13) by the negative pressure formed by the jet pump (13) through the pipeline P1, and under the action of the jet pump (13), the ozone and wastewater are fully mixed and sterilized, and the wastewater Through the pipeline P7 to the liquid distributor (7) at the bottom of the circulatio...

Embodiment 3

[0035] Example 3, such as figure 2 As shown, the present invention provides an ozone disinfection device for medical wastewater. The ozone generator (1) is connected to the side port of the jet pump (13) through the pipeline P1, and the lower port of the jet pump (13) is connected to the circulation tank (5) through the pipeline. P7 connection, the pipeline P7 is inserted from the upper part of the circulation tank (5) to the bottom of the circulation tank (5) and connected to the liquid distributor (7), the circulation tank (5) is connected to the centrifugal pump (9) through the pipeline P3, and the centrifugal pump (9 ) is connected to the upper port of the jet pump (13) through the pipeline P4, the liquid phase ozone detector (6) is installed on the lower side of the circulation tank (5), the pipeline P9 is connected to the upper side port of the circulation tank (5), and the pipeline P9 The other end is connected to the bottom of the getter tank (11), the getter tank (11...

Abstract

The invention discloses a medical wastewater ozone disinfection device and a disinfection process method thereof, and relates to the technical field of medical wastewater disinfection, the device mainly comprises an ozone generator, a circulating tank, a buffer tank, an extraction tank, a jet pump and a centrifugal pump, and the disinfection process method comprises the following steps: injectingquantitative wastewater, circulating the wastewater among the circulating tank, the jet pump and a connecting pipeline, starting the ozone generator and the jet pump to fully mix ozone with the wastewater for disinfection, stopping circulation when ozone in the wastewater at the lower part of the circulating tank reaches a certain concentration, continuously introducing the wastewater again, and continuously overflowing and discharging standard water to form continuous disinfection. The system has the beneficial effects that a traditional chlorine-containing disinfectant dosing system is replaced, negative pressure formed by the jet flow injection system is used as gas conveying power, so that ozone is rapidly and fully dissolved in water, tail gas which is not reacted completely is recycled, the ozone utilization efficiency is improved, and before the tail gas is discharged, the gas enters the extraction tank to further destroy ozone in the tail gas, so that secondary pollution causedby ozone escape is avoided.

Description

technical field [0001] The invention relates to the technical field of medical wastewater disinfection, in particular to an ozone disinfection device for medical wastewater and a disinfection process method thereof. Background technique [0002] In the current medical wastewater treatment, chlorine-containing disinfectants or ozone are mainly used as disinfectants. Disinfection methods mainly include manual disinfection after collection in containers or use of corresponding gas generating devices for disinfection; the main problem of chlorine-based disinfectants is that they are easy to Residues in waste water and easy to cause secondary pollution; use containers to collect and manually add drugs for disinfection, the workload is heavy, and need to directly contact sewage and disinfectants; use corresponding system equipment for disinfection, such as when using an ozone generator for disinfection, the residual ozone The gas will overflow, and there is a danger of ozone leaka...
