Description
Technical field
The utility model is related to Progress in Technology of Hospital Wastewater Treatment fields, and in particular to one kind is suitable for small-middle hospital and small towns
Commune hospital, the more stable scale of water, the biodegradability and sanitary sewage of water quality are essentially identical, and sewage is mainly derived from medical care people
Member uses the integrated USOF hospitals of detergent cleaning and disinfecting medical instrument and the waste water of the discharges such as medical care and patient's daily hygiene
Sewage disposal device.
Background technology
Hospital sewage complicated component contains pathogenetic bacteria, virus, chemical agent, heavy metal, disinfectant, organic solvent, acid
The multiple pollutants matter such as alkali and radioactive isotope, has many characteristics, such as the infection of space-pollution, acute infection and latency, without
The important channel of an epidemic disease diffusion can be become by crossing processing, and seriously pollute environment.
The common Hospital Sewage Treatment method of tradition has biological oxidation process, also known as activated sludge process, is various sewage disposals
The most commonly used traditional treatment method.Using blast aeration, mechanical aeration etc., make a large amount of der Pilz and fungi etc. in sewage
Microbial reproduction, these microorganisms have adsorb and oxidation sewage in harmful substance ability, so as to reduce the COD of sewage and
BOD, sewage is made to achieve the effect that purification.Also some sewage farms using anaerobic and aerobic and method.I.e. in anaerobism mistake
Cheng Zhong, anaerobe breeding, nitrification and absorbing harmful substances in water.The drawback is that a large amount of activated sludge can be generated, and will
Treatment of Sludge is carried out, increases process flow, increases engineering cost, and the secondary pollution to air is caused in aeration process.
Common bio-oxidation process has biological contact oxidation process, bio-disc system, tower biological filter method, jet-flow aeration method and oxidation
Ditch method etc..
In addition there is chemical method, be exactly the throwing suitable chemical agent of people into sewage, aoxidize harmful substance in sewage,
Reach cohesion adsorption precipitation.The method is after traditional biochemical process, is gradually grown up in the late three decades.
1. liquid chlorine：Liquid chlorine with its disinfecting power it is strong, cheap be widely used in tap water and disinfection of hospital sewage.But chlorine
Gas is a kind of yellow poisonous gas of irritant smell, it is impossible to produce chlorine whenever and wherever possible, it is necessary to have special bunkerage and
Chlorination equipment.The adding equipment of liquid chlorine is complicated, is easily corroded, dangerous larger, thus is excessively concentrated in city or population
Region by limitation use.

Product is stable, convenient transportation, and equipment investment is few, and operating cost is low, and management is convenient, safe and reliable, will not be generated because of disinfectant dirty
Mud, application are relatively broad.But hypochlorite disinfectant's ability is weak, and waste residue is brought in processing procedure, is just gradually substituted by other products.
3. Ozone：Ozone is strong oxidizer, and suitable ozone is added in sewage makes microorganism and various gold in water
Belong to ionic oxide formation.Processing hospital sewage is more thorough in this way, and secondary pollution is few.Shortcoming is that mating equipment is more, one
Secondary property investment is big, and maintenance of equipment amount is big, and electricity consumption is also big, increases long-term running cost.
But especially villages and towns in rural areas hospital is generally on the field of population concentration, town.China small towns sewage is concentrated at this stage
It is low to handle emission index, township hospital's sewage is substantially direct or indirect to be discharged into environment water；And the life of our residents from villages and towns
Drinking water source living, mostly positioned at the surface water or phreatic water of neighbouring environment water, thus untreated hospital sewage, right
The Drinking Water of villages and towns in rural areas resident constitutes serious health threat.Thus it is proposed that a kind of integration USOF hospitals are dirty
Water treatment facilities.
