DETAILED DESCRIPTION

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0017] like Figure 1As shown, a drainage system for a community hospital combining peace and epidemic prevention includes: a polluted area 1 and a clean area 2. The first drainage pipe 6 of the polluted area 1 is divided into two routes, one of which is connected to a pre-disinfection tank 10 via a first valve 8, and the other is connected to a septic tank 14 via a second valve 9. The second drainage pipe 7 of the clean area 2 is connected to the septic tank 14, and the septic tank 14 is connected to an integrated sewage treatment station 15. The sewage discharged from the septic tank 14 is treated by the hospital's integrated sewage treatment station 15 and then discharged to a municipal sewage pipe 16, so as to ensure that the sewage discharged by the community hospital meets the requirements of the drainage water quality of the system and avoids pollution to the environment. The outlet of the pre-disinfection tank 10 is connected to the septic tank 14, and a residual chlorine detector 11 is installed at the outlet of the pre-disinfection tank 10. One side of the pre-disinfection tank 10 is arranged to discharge chlorine into the septic tank 14. A dosing device for adding chlorine dioxide is used. During the epidemic period, the first valve 8 is opened and the second valve 9 is closed. The sewage discharged from the first drain pipe 6 enters the pre-disinfection tank 10 for pretreatment. The residence time of the sewage in the pre-disinfection tank 10 is greater than 1 hour. The disinfection method adopts chlorine dioxide disinfection. The residual chlorine detector 11 detects the residual chlorine in the outlet pipe of the pre-disinfection tank 10 in real time. For example, when the residual chlorine content is less than 0.5 mg / L, the dosing device adds chlorine dioxide to the pre-disinfection tank 10, otherwise it does not add chlorine dioxide; there may be virus-containing gas in the first drain pipe 6 that is discharged through the vent pipe 5. Therefore, the vent pipe 5 connected to the first drain pipe 6 is connected to the disinfector 4 to filter and disinfect the gas in the vent pipe 5. The first valve 8 and the second valve 9 are preferably electric valves.

[0018] The septic tank 14 directly collects sewage from the entire hospital during normal times, and collects sewage discharged from the second drainage pipe 7 of the clean area 2 and sewage from the contaminated area 1 after disinfection in the pre-disinfection tank 10 during the epidemic. The sewage stays in the septic tank 14 for no less than 36 hours. The integrated sewage treatment station 15 mainly includes three parts: sewage pretreatment, physical or biochemical treatment, and disinfection treatment. It removes particles carrying viruses and bacteria through coagulation sedimentation (filtration).

[0019] Furthermore: the ventilation pipe 5 connected to the first drain pipe 6 adopts roof ventilation, and the sterilizer 4 is arranged on the roof of the building in the contaminated area 1. The sterilizer 4 may not be activated at ordinary times, but is automatically activated during the epidemic to ensure that the toxic gas in the first drain pipe 6 is completely filtered and disinfected during the epidemic. In this embodiment, the sterilizer 4 can choose to use a nanophoton purification device.

[0020] It should be noted that the dosing device includes: a dosing room 12 located on one side of the pre-disinfection tank 10, a dosing pump 13 is arranged in the dosing room 12, the dosing pump 13 is used to add chlorine dioxide to the pre-disinfection tank 10, the dosing pump 13 is electrically connected to the residual chlorine detector 11, the dosing pump 13 and the residual chlorine detector 11 are linked to realize automatic dosing according to the detection result of the residual chlorine detector 11, so as to meet the automatic dosing of the pre-disinfection tank 10 during operation during the epidemic.

[0021] It should be noted that the entire system also includes: a rainwater pipe 17, which maintains a certain distance from the sewage pipe 16 and is located on different sides of the building. The rainwater pipe 17 and the sewage pipe 16 are tightly sealed to prevent the spread of the virus caused by the mixing of rainwater and sewage during the epidemic. At the same time, an impermeable membrane is laid throughout the contaminated area 1 to prevent pollutants from penetrating into the ground and contaminating the groundwater.

[0022] It should be noted that the first drainage pipe 6 and the ventilation pipe 5 in the contaminated area 1 and the second drainage pipe 7 in the clean area 2 should be independently arranged and strictly separated to prevent diffusion and cross contamination.

[0023] It should be noted that the outdoor sewage system in contaminated area 1 should be connected using pipes without inspection wells, and reliable connection methods such as bonding and hot-melt connection should be used to avoid the spread of pathogens. In order to meet the cleaning requirements, a closed cleaning port should be installed instead of the inspection well, and the cleaning port should be set inside the well chamber.

[0024] It should be noted that the first drainage pipe 6 in the contaminated area 1 should be subjected to a water-tightness test, and measures should be taken to prevent the sewage in the first drainage pipe 6 from seeping out and leaking. Sealing measures should be taken where the drainage pipe passes through floors and walls to prevent the air in different spaces from penetrating each other. Strengthened sealing measures should be adopted for the openings on the walls connecting the clean area, semi-contaminated area and contaminated area.

[0025] It should be noted that a dedicated ventilation system is set up parallel to the sewage network, with the connection distance not exceeding 50 meters.

[0026] It should be noted that the system should ensure continuous power supply to ensure that the system can operate normally and continuously to avoid sudden power outages causing system failures.

[0027] The working principle of the drainage system of the community hospital combined with epidemic prevention and control is as follows:

[0028] The hospital buildings in the community hospital park are divided into a contaminated area 1, a clean area 2 and an outdoor area 3, which can be adjusted and used during normal times and epidemic periods to ensure the normal operation of the hospital drainage system and prevent cross infection. During the epidemic period, the first valve 8 is opened and the second valve 9 is closed. The sewage discharged from the first drainage pipe 6 in the contaminated area 1 enters the pre-disinfection tank 10 for pretreatment. The residual chlorine detector 11 on the outlet pipe of the pre-disinfection tank 10 detects the residual chlorine in the outlet pipe in real time. The residual chlorine detector 11 is linked with the dosing pump 13 for control. When the residual chlorine content is small, it means that the sewage has not been disinfected. The dosing pump 13 is controlled to increase the dosage of the disinfectant until the residual chlorine content meets the requirements. The sewage discharged from the pre-disinfection tank 10 enters the septic tank 14;

[0029] During the non-epidemic period, the first valve 8 is closed, the second valve 9 is opened, and the sewage discharged from the first drainage pipe 6 of the polluted area 1 enters the septic tank 14;

[0030] The septic tank 14 is located behind the pre-disinfection tank 10. The septic tank 14 collects the disinfected sewage of the community hospital and stores it for a short period of time. The integrated sewage treatment station 15 is located behind the septic tank 14 and systematically treats the sewage of the entire community hospital and finally discharges it into the municipal sewage pipe 16.

[0031] The system has a simple structure and is easy to integrate control and system adjustment operation. It can meet the normal operation of the drainage system in normal times and during epidemics, ensure that the sewage discharged by the community hospital meets the system drainage water quality requirements, avoid pollution to the environment, reduce the spread of viruses and cross-infection caused by epidemics, meet the needs of multi-scenario operations in normal times and during epidemics, improve the safety and reliability of drainage system operation, realize the safe and stable operation of the community hospital drainage system, avoid cross-contamination of water quality, reduce the probability of virus transmission, and reduce the chance of infectious diseases due to the drainage system, meet the efficient operation and use of community hospitals in multiple scenarios, and have good technical and economic effects.

[0032] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
