Medical waste water mainly tests room, dining room, bathroom, laundry, toilet, reagent chamber by inpatient department, clinic, reality (change)
The sewage composition of equal places discharge, sewage source and ingredient are sufficiently complex.The sewage is a kind of sewage of low concentration, water quality and one
As sanitary sewage it is similar, but with space-pollution, acute infection and latent infection feature.Medical waste water is wherein removed containing having
Outside machine and inorganic pollutant, such as various drugs, disinfectant, dissection abandon pollutant, also contain a large amount of pathogenetic bacterias, disease
Poison and helminth etc., composition is complex.It is harmless without disinfection, inactivation etc. if the medical sewage containing pathogenic microorganism
Change processing, and it is directly discharged into city sewer, it often will cause the pollution of water, soil, it is serious to cause various diseases, or lead
Cause the outbreak of epidemic of water-borne infection.
Domestic Grade III Class A hospital accounts for about the 5% of all hospital's sums, so 90% or more is all small-middle hospital.And one
As large hospital wastewater flow rate it is big, the medical waste water processing system for investment comparatively perfect of also having the ability, but the hospital of small scale is useless
Water treatment system construction aspect is just weaker, most of only just to discharge through simple disinfection.Medical waste water once repeatedly drew
Public attention is played, just discharge harm caused by water resource is huge without administering, and has become one for endangering health of the masses
" source ", some areas really are able to reach the only several hospital of national emission standard.Currently, law is not
Specification, the weakness of environmental consciousness, cause medical waste water it is in line or " high pollution, low improvement " status.
It is directed to medical waste water at present, most domestic hospital uses secondary biochemical treatment technique, such as: activated sludge process, SBR
Technique, biological contact oxidation process and cyclic activated sludge system biochemical treatment etc..Due to traditional handicraft and equipment design in without good needle
To property and strengthen unit, have much the same treatment effect for the medical waste water of no particularity, and for being more toxic, water quality
Non-uniform medical waste water is then without too apparent treatment effect.And traditional process equipment takes up a large area, is not compact enough, makes
The problems such as being wasted at land used, and peripheral ring is not only influenced with the processing such as sludge, foul smell improperly problem in technological design
Border, it is also possible to cause secondary pollution.
Medical waste water must it is sterile-processed after can discharge, currently used sterilizing equipment decontaminating apparatus be chlorination equipment, including
Chlorine, chlorine dioxide, sodium hypochlorite, wherein be known as effect it is best and it is most widely used be disinfection by chlorine dioxide.But
It is exactly chlorine residue excessive problem in water that a very big problem has been left in chlorination, this index is not paid attention to before, institute
This problem is just ignored from the beginning with the design of most medical waste water equipment, so also producing while administering waste water new
Pollution source problem.
