Description
Technical Field
The utility model belongs to the technical field of medical sewage treatment, in particular to hospital sewage pretreatment device.
Background
The functions, facilities and personnel composition conditions of each department of the hospital are different, and the main departments and facilities for generating sewage comprise: the drainage of diagnosis and treatment rooms, laboratory rooms, ward rooms, laundry rooms, X-ray photo processing and printing, animal rooms, isotope therapy diagnosis, operating rooms and the like. Domestic sewage discharged by administrative management and medical staff of a hospital is discharged from a dining room, a single dormitory and a family dormitory. The sewage components and the water amount generated by departments of different departments are different, such as heavy metal wastewater, oily wastewater, printing wastewater, radioactive wastewater and the like. But also the sewage generated by hospitals with different properties is very different. The hospital sewage is more complex than the general domestic sewage in discharge, and besides the general domestic sewage, the hospital sewage also contains chemical substances, radioactive waste water and pathogens. Therefore, the sewage can be discharged after being treated, in particular, the sewage discharged from the infectious disease wards such as hepatitis and the like can be discharged after being disinfected.
At present, hospitals without centralized sewage treatment equipment have to sterilize infectious excrement independently to make the excrement harmless. Common disinfectants include chlorine dioxide, bleaching powder, liquid chlorine, sodium hypochlorite, and ozone. Sewage containing radioactive isotope should be treated according to the isotope treatment requirement. In the hospital sewage treatment process, the precipitated sludge contains a large amount of bacteria, viruses and parasitic ova, and can be used as fertilizer after being disinfected (generally disinfected by slaked lime) or high-temperature composting.
In conclusion, the workload and difficulty of the subsequent treatment of the hospital sewage are so great that if the sewage is simply pretreated at the source, large-particle medical wastes (such as cotton, blood clots and the like) are separated in advance, the difficulty of the subsequent treatment is greatly reduced, and the hazard source can be blocked at the first time.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the background art, the utility model provides a hospital sewage pretreatment device can carry out the preliminary treatment to it at the head of sewage production, and the large granule medical waste who will mix in sewage filters, and has from the function of decontaminating.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a hospital sewage pretreatment device, includes the sewage jar, the sewage jar includes the horn mouth at top and sets up the shell of horn mouth below, be equipped with the filter screen in the shell, the horn mouth communicates with the inside filter screen of shell, the lower part of filter screen links to each other with the filth valve, the side bottom surface of shell is equipped with the sewage valve.
Further, the filter screen is arranged in the shell through an electric rotating shaft and can be driven by the electric rotating shaft to rotate.
Further, a pressure sensor is additionally arranged on the filter screen and provided with a preset value range, the pressure sensor detects that the internal pressure of the filter screen is within the preset value range, the sewage valve is opened, the sewage valve is closed, and when the pressure sensor detects that the internal pressure of the filter screen exceeds the preset value, the sewage valve is controlled to be closed and opened.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model carries out the first-hand pretreatment at the source of the hospital sewage, effectively filters the sewage which is easy to mix in the sewage (because the medical wastes such as needles, tubes and blades can be classified and collected in the current hospital, the hard and sharp medical wastes in the waste water are generally less), reduces the subsequent treatment difficulty; the convenient to popularize and apply is in the middle of the administrative or technical offices or even the ward of being in hospital, can in time carry out the first hand to hospital's sewage fast and handle, avoids the sewage that leads to for a long time further volatilize, backward flow, fermentation scheduling problem for a long time.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
the device comprises a bell mouth 1, a shell 2, a filter screen 3, an electric rotating shaft 4, a sewage valve 5, a sewage valve 6 and a pressure sensor 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
