The invention discloses a sewage treatment system with a sterilization function. The system comprises a contact oxidation tank, wherein the contact oxidation tank comprises a tank body, a filler support, aerobic filler, a microporous aerator and a rotary fan; one end of an air inlet pipe of the contact oxidation tank is communicated with the rotary fan, and the other end of the air inlet pipe is connected with the microporous aerator; the filler support is arranged in the contact oxidation tank and the aerobic filler is arranged on the filler support; the air inlet pipe comprises a main pipe and branch pipes, the main pipe is communicated with the rotary fan, ends of the branch pipes are uniformly arranged in the axial direction of the main pipe and communicated with the main pipe, and theother ends of the branch pipes are communicated with the microporous aerator; the diameter of the main pipe is gradually changed from one end to the other end, and the diameter of one end connected with the rotary fan is smaller than that of the other end. According to the sewage treatment system, the diameter of the end, far away from the fan, of the main pipe is larger, so that airflow pressurein different branch pipes is more uniform, aeration of the microporous aerator is more uniform, and the biological oxidation effect in a base oxidation tank can be improved.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment equipment, in particular to a sewage treatment system with a sterilization function. Background technique [0002] Hospital sewage, in addition to general domestic sewage, also contains chemical substances, radioactive wastewater and pathogens. Therefore, it must be treated before it can be discharged, especially the sewage discharged from infectious disease wards such as hepatitis must be disinfected before it can be discharged. For hospitals without centralized sewage treatment equipment, infectious feces must be sterilized separately to make them harmless. Commonly used disinfectants include bleach, liquid chlorine, sodium hypochlorite, and ozone. During the treatment of hospital sewage, the precipitated sludge contains a large number of bacteria, viruses and parasite eggs, which must be disinfected (usually slaked lime disinfection) or high-temperature composting before it can be us...
