Problems solved by technology

[0003] With the development of science and technology, the progress of society, and the continuous improvement of people's concept of environmental protection, the requirements for sewage discharge are also getting higher and higher, especially the sewage discharged from hospitals. Sewage treatment devices are required for hospital sewage treatment. However, most of the reaction tanks in the current sewage treatment devices use low-efficiency clapboard reaction tanks, and most of the sedimentation tanks use ordinary sedimentation tanks, which leads to the problem of low sewage treatment efficiency in the existing hospital sewage treatment process. Therefore, We propose a hospital sewage treatment process

Embodiment 1

[0028] First, primary treatment: discharge hospital sewage into septic tanks, through which some impurities are precipitated and anaerobic decay is carried out, thereby killing mosquito eggs: then preliminary filtration: filter sewage through grilles , so as to remove suspended solids, masks and gauze, etc.; then adjust: discharge the sewage into the regulating tank, so that the regulating tank can adjust the water flow, and at the same time carry out preliminary sedimentation of the sludge: then preliminary separation: through the submersible sewage pump The sewage in the regulating tank is discharged into the biofilter, and the sewage is in contact with the microbial film growing on the surface of the filler to purify the sewage. At the same time, the sludge at the bottom of the regulating place is discharged into the sludge digestion tank through the sludge pump. In the tank, after being degraded by facultative microorganisms and obligate anaerobic microorganisms, the organi...

Abstract

The invention discloses a hospital sewage treatment process. The hospital sewage treatment process comprises the following steps: performing primary treatment: discharging hospital sewage into a septic tank and performing anaerobic decay while precipitating impurities through the septic tank so as to kill mosquito and fly eggs; and performing primary filtration: filtering the sewage through grilling so as to eliminate suspended materials, a mask and gauze. A honeycomb inclined pipe heterodromous precipitation pool is provided and the sewage precipitation speed is increased, so that the sewagetreatment progress is increased and the sewage treatment time is saved; a power mixed reaction pool is provided, and obvious improvement is achieved relative to that a partition plate reaction pool mixes the sewage and a coagulant for about 20 minutes through the water flow speed and the assistance of the partition plate, so that the sewage treatment progress is increased, the sewage treatment efficiency is improved and the problem in the existing hospital sewage treatment process that the sewage treatment efficiency is low is solved.

Description

technical field [0001] The invention relates to the technical field of hospital sewage treatment, in particular to a hospital sewage treatment process. Background technique [0002] Hospital sewage, in addition to general domestic sewage, also contains chemical substances, radioactive waste water 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 with centralized sewage treatment equipment, infectious feces must be sterilized separately to make them harmless. [0003] With the development of science and technology, the progress of society, and the continuous improvement of people's concept of environmental protection, the requirements for sewage discharge are also getting higher and higher, especially the sewage discharged from hospitals. Sewage treatment devices are required for hospital sewage treatment. How...
