Hospital sewage treatment treatment process is based on the size of the hospital, the nature and treatment of sewage discharge destination, process selection.
Hospital wastewater treatment treatment process is mainly used in three processes: to strengthen the treatment effect of primary treatment, secondary treatment and simple biochemical treatment.
Hospital wastewater treatment process is generally taken to the engineering design, construction and acceptance of the operation and management practices, its treatment facilities need to undergo a certain period of trial operation, the treatment effect to achieve the desired purpose. Chemical treatment requires one month of trial operation, secondary biochemical treatment requires more than three months of trial operation.
1. Usually use physical + biochemical method treatment process, the treatment of hospital wastewater treatment of the main processes are: flocculation and sedimentation (physical) + hydrolysis acidification (biochemical) + depth oxidation (biochemical) + disinfection --- up to the standard discharge
Flocculation and sedimentation (physical) + hydrolysis acidification (biochemical) + MBR (biochemical) + disinfection --- > up to the standard discharge
2 ...Treatment of hospital wastewater treatment process materialization: mainly to allow microorganisms can not decompose the harmful precipitation, flocculants, coagulants and other chemicals will be added to the sewage, the harmful substances will be transferred to the sludge, through the treatment of sludge to achieve the purpose.
Hospital wastewater treatment treatment process biochemical: is the human discovery of microorganisms in the natural water decomposition of organic matter, analysis and summary: microorganisms in different environments can decompose different harmful substances, the general use of anaerobic bacteria + aerobic bacterial cultures, i.e., hydrolysis acidification and deep oxidation.
3. Hospital wastewater treatment treatment process disinfection method
There are many ways to disinfect hospital wastewater, such as liquid chlorine, ozone, sodium hypochlorite, chlorine dioxide and so on. But the commonly used disinfection method is: chlorination method which has the advantages of casting formula, low price, high reliability, ozone method for hospital sewage disinfection, can effectively kill coliform bacteria, polio and other viruses. And it is not affected by the content of ammonia and nitrogen in wastewater and pH value
