Overview:
The integrated ceramic membrane medical sewage purification and disinfection equipment (CMMT) integrates biological methods (activated sludge), physical methods (ceramic membrane filtration) and chemical methods (chlorine disinfection) to achieve efficient and stable removal of organic matter, inorganic matter, bacteria and viruses in medical wastewater.
Processing principle:
(1) The principle of whole-process control: control the whole process of hospital sewage generation, treatment and discharge.
(2) Reduction principle: strict internal health and safety management system of the hospital, strict control and separation of sewage and sewage sources, rainwater, domestic sewage and ward sewage in the hospital are collected separately, that is, source control, sewage cleaning and diversion. It is strictly forbidden to dispose of the sewage and sewage of the hospital into the sewer (which is hazardous waste).
(3) The principle of on-site treatment: In order to prevent pollution and harm in the process of hospital sewage transportation, it must be treated locally in the hospital.
(4) Classification guidelines: Classification guidance for hospital sewage treatment is carried out according to the nature, scale, sewage discharge destination and regional differences of hospitals.
(5) The principle of combining compliance and risk control: comprehensively consider the basic requirements of sewage discharge in general hospitals and infectious disease hospitals, strengthen the awareness of risk control, and improve the ability to respond to emergencies from the aspects of process technology, engineering construction and supervision and management.
(6) Ecological safety principle: effectively remove toxic and harmful substances in sewage, reduce the production of disinfection by-products in the treatment process and control excessive residual chlorine in the effluent, and protect the safety of the ecological environment。
◆ Anaerobic zone: high-efficiency filler, adsorption, hydrolysis, ammoniation
◆ Aerobic zone: high sludge concentration, biochemical degradation
◆Membrane area: the sixth generation of inorganic nano-ceramic membrane (pore size 50~100nm) separation, the first disinfection, can physically block all non-viral microorganisms (100~ 5000nm) and new coronavirus (125nm)
◆ Disinfection area: quantitative second contact disinfection of subsodium, double insurance
Merit:
◆ Integrated, small footprint, good effluent quality, membrane pore size of 50~100nm, can effectively separate Escherichia coli, new coronavirus and other microorganisms, the physical filtration of the membrane can be used as the first guarantee of effluent
◆The anaerobic zone is equipped with high-efficiency filler, which strengthens the ammonia and hydrolysis of the anaerobic zone and improves the biodegradability of organic pollutants in medical sewage
◆ The sludge concentration of aerobic system operation can be as high as 20000mg/L, which improves the impact resistance of the system, the sludge age is long, the sludge output is only 1/3 of the traditional process (belonging to hazardous waste), and no chemical sludge is generated, which greatly reduces the secondary pollution spread caused by sludge transfer
◆The life of the membrane is more than 15 years, and there is no risk of membrane material replacement and secondary pollution
◆ The membrane material has strong chemical stability, high temperature resistance, acid and alkali resistance, and can be widely used in various water quality
