Hospital sewage and sludge automatic separation and filtering system

Abstract

A hospital sewage and sludge automatic separation and filtering system comprises a sewage bin provided with a bottom cone, a sewage output pipeline mounted on the bottom cone of the sewage bin, a water inlet nozzle located in the sewage bin and mounted on the sewage output pipeline, a mesh filter connected to the sewage output pipeline through two flange plates and fastening bolts, a straight-through pipe vertically mounted on the sewage output pipeline and communicated with the atmosphere, a filtered water drainage pipe mounted at the tail end of the sewage output pipeline, and a sterilization and disinfection treatment tank placed at the lower end of the filtered water drainage pipe. The hospital sewage and sludge automatic separation and filtering system provided by the invention occupies small space; after sludge is settled, water is automatically drained; the mesh filter can be cleaned and replaced at any time; maintenance is simple and convenient; sterilization and disinfection and sewage treatment effects are good; treated clean water can be recycled; water pollution is eliminated; the environment is protected; and zero discharge of the sewage is realized. The hospital sewage and sludge automatic separation and filtering system can be widely applied to a hospital sludge water treatment process.

Description

technical field [0001] The invention relates to an automatic separation and filtration system for hospital sewage and sludge, which can be widely used in the treatment process of hospital sludge water. Background technique [0002] Medical sewage is mainly the sewage discharged from the hospital's consulting room, laboratory, ward, laundry room, X-ray room and operating room, etc. The source and composition of the sewage are very complicated. Hospital sewage contains a large number of pathogenic bacteria, viruses and chemical agents, and has the characteristics of space pollution, acute infection and latent infection. Medical wastewater has attracted public attention many times. The discharge of medical wastewater has caused great harm to water resources and has become a "source" that endangers public health. In some areas, only a handful of hospitals can truly meet the national discharge standards. At present, irregular laws and weak awareness of environmental protection h...

AI Technical Summary

Problems solved by technology

At present, the irregularity of laws and the weak awareness of environmental protection have resulted in the direct discharge of medical wastewater and the current situation of "high pollution and low governance" in major hospitals.

[0003] At present, China's medical waste disposal mode is centralized treatment, and the state has made detailed regulations on the problems in the collection, storage, handover, transportation, and treatment of medical waste liquid; although the state consumes a lot of manpower in the treatment of medical waste liquid Material resources, but the transportation and storage link is still the most problematic link of medical waste liquid at present, and it is also the most serious problem link; because the waste liquid treatment center adopts the principle of "one city, one station", many medical institutions are far away from the treatment center, and these wastes contain a large number of bacteria There are certain characteristics of space pollution, acute virus infection and latent infection. If the management of medical waste liquid is not strengthened during the transportation and storage process, it is discarded at will, and it is allowed to mix with domestic waste and disperse into people's living environment. Pollution of air, water sources, land, animals and plants, causing disease spread, seriously endangering people's physical and mental health; most of the waste liquid produced by the existing operating room care is treated by drying and incineration measures, and the waste liquid contains waste. At the same time, during the treatment process, the waste liquid is easy to evaporate and gasify, thus spreading into the air, causing the spread of bacteria

[0004] Existing hospital sewage treatment usually includes multiple sub-units such as hydrolytic acidification unit, biological contact oxidation unit, secondary sedimentation tank unit, contact disinfection unit, etc., involving many devices and huge equipment. In health centers and hospitals, its application is limited. In addition, due to various design or manufacturing reasons, the existing devices still have some problems of poor treatment effect and low degree of automation, which make them unable to meet the needs of hospital sewage treatment.
