Description
Technical field
The present invention relates to sewage treatment area, particularly about a kind for the treatment of unit about medical sewage.
Background technology
Medical sewage is mainly from the sewage that the consulting room of hospital, laboratory, ward, laundry, X sheet photo studio and Operation theatre etc. discharge, and its sewage source and composition are very complicated.Containing a large amount of pathogenetic bacteria, virus and chemical agent in hospital sewage, there is the feature of space-pollution, acute infection and latent infection.
Settling tank water outlet enters antisepsis contact tank, makes the contact residence time that sewage and sterilizing agent keep certain, and ensure that sterilizing agent kills bacterium in water effectively, Chinese effluent is to city planting ductwork.Require that infectious hospital's waste water time should not be less than 1.5 hours according to " Discharge standard of water pollutants for medical organization " (GB18466-2005), integrated hospital wastewater should not be less than 1.0 hours duration of contact.Beijing hospital is the general hospital polyclinic containing contagious department, so the hydraulic detention time of antisepsis contact tank adopts 1.5 hours.Adopt buried skeleton construction, together with building jointly with other processing unit, save initial cost, the upper earthing of Chi Ding, for maintenance and inspection are convenient, be provided with inspection window at the edge of contact-oxidation pool, can regularly safeguard equalizing tank.Why " Discharge standard of water pollutants for medical organization " (GB18466-2005) requires that infectious hospital's waste water time should not be less than 1.5 hours, integrated hospital wastewater should not be less than 1.0 hours duration of contact, major cause is sterilization is the key link of medical sewage, by extending the waste water time, thus guarantee that sewage fully contacts with sterilizing agent, ensure that sewage obtains sufficiently sterilised as far as possible, the waste water time longer in antisepsis contact tank, cause the decrease in efficiency that antisepsis contact tank is disposed of sewage, for ensureing that the sewage of hospital can obtain blowdown timely and process, can only the size of antisepsis contact tank be done very large, but because medical sewage treatment unit is positioned at the area, down town of an inch of land is an inch of gold mostly, buried structure can only be adopted, but the excessive antisepsis contact tank of floor space makes medical sewage treatment unit entirety excessive undoubtedly, the earth subsidence problem that easy initiation modern metropolitan cities is worried most, in addition, the excessive medical sewage treatment unit of area can bear larger hydraulic pressure and stronger sewage, the etching problem of sewage-treating agent, to the intensity of medical sewage treatment unit, there is higher requirement, both technical difficulty was increased, turn increase construction cost.
The bacterium of broad sense is prokaryotic organism and refers to that a large class nucleus wraps up without nuclear membrane, only there is the primordial unicellular organism being called the naked DNA in nucleoid district (or nucleoid).The bacterium of narrow sense that what people were usually said be, the bacterium of narrow sense is a class of prokaryotic micro-organisms, that a class shape is carefully short, structure is simple, the prokaryotic organism bred are carried out mainly with binary fission mode, being at the organism that distributed in nature is the widest and individual amount is maximum, is the Primary Actor of the Nature material cycle.But a lot of bacterium is with pathogenic, infringement human and livestock health, must be eliminated in the process of sewage disposal for the bacterium in sewage, the place that especially this pathogenic agent of hospital is concentrated, strictly must control the external infringement of bacterium in sewage treatment process.
