Embodiment 1

[0050] see figure 1 A treatment process for wastewater from a medical waste disposal plant, including disinfection of vehicles and turnover boxes, disinfection wastewater for cleaning, medical waste leachate, domestic sewage, workshop wastewater, and primary rainwater. Wastewater from medical waste disposal plants is different from medical waste water. Wastewater from medical waste disposal plants mainly comes from medical waste high-temperature steam sterilization disposal plants or medical waste incineration disposal plants. Wastewater from medical waste high-temperature steam sterilization disposal plants mainly includes vehicle and turnover box cleaning and disinfection wastewater, medical waste leachate, domestic sewage, condensate produced in the inner cavity of high-temperature steam treatment equipment, condensate during waste gas treatment, workshop Ground flushing waste water, etc. The chlorine disinfection process used in general disinfection treatment has a great ...

Embodiment 2

[0079] This embodiment is an improvement made on the basis of Embodiment 1. For the same part as Embodiment 1 in this embodiment, please refer to the content disclosed in Embodiment 1 for understanding, and the content disclosed in Embodiment 1 should also be used as this embodiment. The content of the example will not be repeated here.

[0080] For the treatment process described in embodiment 1, the present embodiment also includes the process of backwashing the filter device; the waste water produced in the backwash process of the disinfection wastewater treatment process in the present embodiment can be discharged into the sedimentation tank, and mixed with other waste water They are treated together and recycled to achieve zero discharge of sewage, and can also be discharged into the sludge tank.

Embodiment 3

[0082] This embodiment is an improvement made on the basis of Embodiment 1. For the same part as Embodiment 1 in this embodiment, please refer to the content disclosed in Embodiment 1 for understanding, and the content disclosed in Embodiment 1 should also be used as this embodiment. The content of the example will not be repeated here.

[0083] In this embodiment, the primary rainwater described in Embodiment 1 is the flushing rainwater of the medical waste disposal plant collected within 15 minutes of the first rainfall. Medical waste mainly includes: infectious waste, pathological waste, traumatic waste, pharmaceutical waste, chemical waste, etc. Because medical waste contains a large amount of bacteria and organic matter, the rainwater of the medical waste disposal plant also contains certain organic matter. Therefore, the primary rainwater of the medical waste disposal plant needs to be treated, and cannot be directly discharged into the municipal sewage pipe or directly ...

Abstract

The invention relates to a process and an apparatus for treating waste water in a medical waste disposal plant. The process is used to treat a variety of waste water respectively and comprises treatment of disinfection waste water produced in disinfecting and cleaning of vehicles and pass boxes, treatment of leachate of medical waste and domestic sewage, and treatment of waste water of a workshop, effluent of a sedimentation basin and primary rainwater. The apparatus for treating waste water comprises a disinfection waste water treating device, a medical waste leachate treating device and an in-depth treating device. According to the invention, waste water in a medical waste disposal plant is treated by respectively using a physicochemical treating process and a biochemical treating process, and reclaimed water is reused at the same time; the treating apparatus has the advantages of small investment, low operational cost, simple operation and saving of the water resource.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a waste water treatment process and device of a medical waste disposal plant. Background technique [0002] Medical waste refers to directly or indirectly infectious, toxic and other hazardous waste produced by medical and health institutions in the course of medical treatment, prevention, health care and other related activities. Medical waste pollutes the environment, spreads diseases, and threatens health. It is very harmful. It is the primary waste among the 47 types of hazardous waste in the "National Hazardous Waste List". Since the implementation of the "National Hazardous Waste and Medical Waste Disposal Facilities Construction Plan" in 2003, technical routes such as rotary kiln incineration, pyrolysis incineration, steam sterilization, and microwave disinfection have been mainly used for medical waste disposal. The sewage treatment of medical waste disposal plant...
