Studay And Design The Process Of Small Hospital Sewage Treatment And Effect

Medical concentration of wastewater organic pollution and urban sewage aresimilar, but has its own specialty-general hospital sewage water in addition tocontaining organic pollutants, but also contains some specific pollutants, such as drugs,disinfectant, diagnostic reagents, especially laundry rooms, laboratories, inpatientdepartment of sewage water, containing a large number of parasite eggs and bacteria,viruses and other pathogenic microorganisms. At present, the treatment of hospitalwastewater main physical, chemical and biological methods. Usually based on hospitalsize, nature and treatment of sewage discharge where the process selection, mainly inthe primary treatment, secondary treatment and biological treatment three treatmentprocesses.The small hospital in Northeast hospital wastewater, the Meihekou hospitalsewage treatment process design and operation, for example, a wastewater treatmentprocess to increase the biological regulation pool, the precipitation of dosing, thisthree-step negative pressure microfiltration process designed to strengthen a "process,the final selection of the ozone to complete the disinfection. Ozone as a dedicatedozone generators, low running costs.This study designed to strengthen all the structures of a sewage treatment processfor underground structures, and stamped with insulation in order to apply to thenortheast alpine region. Hospital wastewater unhandled have a certain odor, in order toavoid its emptying directly affect the quality of ambient air required the introduction ofdisinfection the Ikegami Ministry, through the pipe to collect the overflow pooldisinfection, ozone exhaust odor removal. Vacuum micro filter selection, taking intoaccount the precipitation is not sufficient, to further ensure the removal of effluent SS,but also reduce the COD, has greatly improved the subsequent disinfection effect.Microbubbles after the jet hybrid technology to improve disinfection efficiency;disinfection pool set baffle, increasing the contact time of ozone and water more evenlymixed, better disinfection. Ozone disinfection has a fast response, vote less; adaptable,pH5.6~9.8, the water temperature range of0~37℃, the performance of ozonedisinfection, no secondary pollution.This process has been stable operation of the year, water quality and stabilitystandards. This process has the processing capabilities, wide range of applications; Inaddition, a simple, stable, low processing costs, has a wide range of applications in thesmall hospital in northern wastewater treatment, has a positive processing of promoting small hospital wastewater significance.
