[0001] The utility model relates to the technical field of medical wastewater treatment, in particular to an improved medical wastewater quantitative disinfection pretreatment system, which is mainly used for the disinfection pretreatment of medical wastewater. Background Art
[0002] Medical wastewater contains a large number of pathogenic bacteria, viruses, and chemicals, and is characterized by spatial pollution, acute infection, and latent infection, making it very harmful. If medical wastewater containing pathogenic microorganisms is discharged directly into urban sewers without undergoing harmless treatment such as disinfection and inactivation, it will often cause water and soil pollution, and in serious cases, it will cause various diseases or lead to the outbreak of waterborne infectious diseases. The authorization announcement number is CN219689446U, and the patent name is: A medical wastewater quantitative disinfection pretreatment system. This is the first medical wastewater disinfection pretreatment system developed by the applicant. It can disinfect wastewater to ensure that medical wastewater meets discharge standards and reduce the risk of environmental pollution and disease infection. However, after a period of operation, it was found that this system still has the following problems: due to the high concentration of some medical wastewater, it is easy to form sediment on the inner wall of the buffer box. After reaching a certain amount, it will fall off by itself and block the drain pipe, resulting in the inability to operate the disinfection and discharge procedures normally. Therefore, it is necessary to improve the original medical wastewater quantitative disinfection pretreatment system. After the improvement, the cache box can be automatically flushed in all directions to dilute the wastewater to prevent the wastewater from forming sediment on the inner wall of the barrel and clogging the drain pipe, so as to achieve the purpose of normal operation of the disinfection and discharge program.

[0005] Furthermore, the timer is connected in parallel with the original quantitative disinfection control device and in parallel with the positive and negative poles of the power supply.
[0006] The beneficial effects of the present invention are as follows: by adding a timed automatic cleaning device above the cache box of the original quantitative disinfection control system, the present invention starts the automatic cleaning program at a fixed time every day to automatically flush the cache box in all directions, diluting the wastewater to prevent the wastewater from forming sediment on the inner wall of the cache box and clogging the drain pipe, so as to achieve the purpose of normal operation of the disinfection discharge program. The wastewater generated by the cleaning is sequentially fed from the cache box into the disinfection box, and is processed according to the normal disinfection program before being discharged, thus avoiding environmental pollution. The above improvement can fundamentally solve the problem of the disinfection discharge program not being able to operate normally due to sediment clogging the drain pipe.
