Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of efficient hospital sewage processing process.
Background technology
In recent years, with China's expanding economy, scale, the quantity of hospital are continuously increased, and with vitamin, antibiosis
The medicines such as plain, advanced Medical Devices, the introducing of equipment, give up produced by comparing present hospital compared with early stage unicity hospital sewage composition
Water constituent is complicated, intractability increase.Conventional biochemical processing mainly has two kinds of techniques of A/O and SBR, but is tested by Practical Project
Demonstrate,prove both techniques and there are shortcomings, such as：A/O techniques are made up of hydrolysis acidification and Aerobic Pond two parts, major defect one
It is that the more single pond of construction investment is higher, the removal of ammonia nitrogen in sewage must be by mixed-liquor return in O ponds（Or second pond supernatant is returned
Stream）To A ponds, nitrate nitrogen is changed into nitrogen under anoxic conditions and removed, so A ponds, B ponds must be supported the use, it is indispensable,
Two be to verify size often more difficult control in practical operation that mixed liquor is measured in reflux course through practical experience, and three be specification
In require that A ponds HRT is 2.5h-3h, but be due to the backflow of mixed liquor, if continuing to keep constant HRT, cause A Chi Chi to hold
Increase about 20% before relatively flowing back, four be due to the introducing of the medicine with antibiotic, hospital sewage complicated component, biodegradability compared with
Difference, to ensure effective removal of the follow-up O ponds to organic pollution materials, in A ponds hydrolysis must occur for sewage, by difficult degradation
Organic pollution materials change into degradable simple organic matter, but the process will have to the difficult chain rupture material such as antibiotic
Longer HRT, according to practical experience, generally requires 8-12h, is 3.2-4 times of HRT as defined in specification, five be A needed for effect degraded
Preference temperature is typically run for 15-40 DEG C in pond, so in the winter time due to being limited by temperature, its treatment effect is undesirable, often
It is difficult to ensure that ammonia nitrogen is up to standard, especially in northwest cold district；SBR techniques are that sequencing batch active sludge is imitated with the PROCESS FOR TREATMENT
It is really good, but had the following disadvantages in Hospital Sewage Treatment：One is that the technique is suitable for 800 less doctors of the following water of bed
Institute, two be the technique in actual motion compared with unmanageable, and general most hospital lacks the operational management personnel of specialty, goes out
Existing " build must rise, afford to use, unmanageable " situation.
The content of the invention
There are problem present in technology and defect for above-mentioned, of the invention is a kind of efficient Hospital Sewage Treatment of offer
Technique, technique capital cost reduction 20-30%, system run all right, capacity of resisting impact load are strong, and operational administrative is simple.
Realizing the technical scheme that foregoing invention purpose is used is：A kind of efficient hospital sewage processing process, including it is following
Step：
1）Hospital's cesspool sewage is from placement swinging mechanical grille in frame trough, the frame trough is flow to, using stainless steel machine
Frame, pitch 5mm, for removing suspended pollution material larger in sewage, to prevent the blocking of subsequent pipeline equipment；
2）Step 1）On the one hand processing raw water carries out homogeneous homogenizing from flowing in aerating regulation pond to sewage, is on the other hand exposing
Gas bar part goes down except part organic pollution materials in sewage, reduces subsequent treatment load；
3）Step 2）The processing boosted pump of raw water is promoted to MBBR ponds, is aerated using swinging blower fan, and organic matter is provided
Oxygen, carries out Organic Pollution material and ammonia nitrogen carries out degradation treatment；
4）Step 3）Processing raw water, which is flow automatically to efficient filtering settling pond, carries out the removal of mud-water separation and suspended particulate contaminants matter；
5）Step 4）Raw water enters intermediate pool through pipeline after processing, and a part is by the backwashing pump that is set in intermediate pool to efficient
Filtering settling pond is periodically backwashed according to pressure difference, and backwash water outlet flow to aerating regulation pond and handled again；
6）Step 4）Raw water another part enters sterilization pool, the chlorine dioxide that sterilization is produced using chlorine dioxide generator after processing
Sewage is carried out disinfection through pipeline self to sterilization pool, it is sterilized after sterilization pool water outlet be used for chlorine dioxide generator and giving
Water, redundance outside pipeline through draining into city planting ductwork；
7）The sludge of precipitation enters sludge concentration tank through pipeline in high efficiency filter sedimentation basin, and anaerobism concentration is carried out to it
Afterwards, supernatant flow to aerating regulation pond certainly and handled again；
8）Step 7）Sludge after concentration enters folded spiral shell formula dewaterer through pipeline and carries out sludge dewatering treatment, the dry mud warp after dehydration
Transported after sterilization to the processing of solid waste processing center, the supernatant after concentration and the water through folded spiral shell formula dewaterer disengaging are through pipe
Road to aerating regulation pond.
A kind of efficient hospital sewage processing process main technique of the present invention is " mechanical grille+aerating regulation pond+MBBR+
High efficiency filter sedimentation basin+sterilization ".Grid is passed through in septic tank effluent gravity flow, to remove the suspended material that particle in sewage is larger；Lattice
On the one hand grid water outlet enters homogeneous homogenizing from aerating regulation pond is flow to sewage, and on the other hand removing small part by preaeration has
Organic pollutants matter reduces the processing load of subsequent cell；Aerating regulation pond discharges water to MBBR ponds（Denomination of invention：A kind of high efficiency
MBBR reaction units, the patent No.：201621103331.9）With removal under MBBR filler specials, special bacteria and aeration condition
Organic pollution materials and ammonia nitrogen in sewage, clearance are up to more than 90%, and the sewage self-flowing handled through MBBR is heavy to high efficiency filter
Shallow lake pond carries out the filtering of mud-water separation and suspended particulate；Water outlet is sterilized reaches for filtering《Discharge standard of water pollutants for medical organization》
GB18466-2005 discharge standards, sewage qualified discharge after realization processing can also be returned to sewage after processing according to the actual requirements
With for afforesting, irrigating.The technique is controlled using PLC simultaneously, solves west area managerial personnel and fund in pairs
The problem of shortage.
A kind of the characteristics of efficient hospital sewage processing process of the present invention is the same of the organic matter removal in meeting to sewage
The abjection of Shi Shixian ammonia nitrogen in sewage, so compared with traditional hospital sewage processing process, capital cost reduction 20-30% is
The stable, capacity of resisting impact load of system is strong, the advantage such as operational administrative is simple.It is poly- from new special using folded spiral shell dewaterer
Ethylene modified filler, effective ratio surface 500m2/m3, porosity is up to 85%, and density is slightly less than water, its material high purity, is difficult
Breakage, service life 20 years, and only need a small amount of aeration or slight agitation to can reach fluidized state, make filler complete with waste water
It is complete to combine, improve processing speed.
