According to the principle of fluid mechanics and the law of conservation of energy, the equipment skillfully converts potential energy into kinetic energy, and adopts the technological process of "septic tank sewage → grid well → quantitative pool (unpowered integrated equipment) → mixed well → contact disinfection pool → sampling well → discharge", so that the treated sewage completely meets the requirements of the national standard GB 18466—2005 Discharge Standard of Water Pollutants for Medical Institutions. Tested by health and epidemic prevention and environmental protection agencies, it has been used in hundreds of hospitals all over the country, which proves that the equipment is reasonable in design, advanced in technology, stable in performance, safe in use, and the technical performance ranks first in China. It is suitable for large, medium and small hospitals, medical colleges, rural health centers and medical clinics. This equipment is a national patented product (patent number: 96220373.4), which has passed the appraisal of scientific and technological achievements in Guizhou Province, won the second prize of scientific and technological progress in Guizhou Province, and has been included in the national key promotion plan of scientific and technological achievements and national key new products. The equipment has the following characteristics:
1, high degree of automation and stable disinfection effect.
The equipment can realize the automation of the whole process of hospital sewage treatment without power supply; It can satisfactorily solve the problems of uneven hospital sewage flow and difficult control of dosing concentration, accurately control the thickness of water layer, and thus flexibly adjust the sewage flow. Moreover, according to different properties and needs, the dosage of disinfectant can be freely adjusted through the adjustment mechanism to ensure the disinfection effect.
2. Wide adaptation range
This equipment is an ideal sewage disinfection equipment, which can operate normally in a very low drop state. The civil structures supporting the equipment can be scattered underground, occupying less or less land and without power supply. Suitable for large, medium and small hospitals, medical colleges, rural health centers and medical clinics.
3. Significant economic benefits.
The use of this equipment does not need sewage pump, metering pump, chlorinator, vacuum pump, electronic liquid level controller, console and other electromechanical equipment, which can save about 50% of the equipment investment cost and greatly reduce the operation and management cost.
4. Convenient management, safety and reliability
Due to the high degree of automation, the equipment can be calibrated once to ensure the long-term disinfection effect, which saves time and effort for managers and only needs one person in charge to complete the task.
5, long service life
The equipment adopts plastic steel structure, which is not corroded by acid, alkali and salt, does not need power supply, has no friction and mechanical wear, has long service life and does not need frequent maintenance.
6. Wide application range
The equipment can use oxidizing bactericides such as sodium hypochlorite, calcium hypochlorite, sodium dichloroisocyanurate, potassium persulfate complex, chloramine, chlorine dioxide, liquid chlorine, non-oxidizing bactericides such as dodecyl dimethyl benzyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, dithiocyanomethane, and viscous bactericides such as rosin amine, hydrogen peroxide and guanidine polymer. The maximum dosage is more than 60 mg/L. In addition to ensuring the contact time, the residual chlorine can be flexibly increased or decreased according to the nature of the hospital and the national discharge standard, and generally can be adjusted at will between 3 and 9 mg/L.
