Description
It is on July 30th, 2014 applying date that the present invention, which is, and the patent application of Application No. 201410368768.4 is " seasonal
The divisional application of high turbid original sub-block technique ".
Technical field
A kind of reply seasonal high turbidity raw sewage treatment process of the present invention involved in water supply and sewage work, specifically
A kind of combined treatment process for being applied to take seasonal high turbidity raw sewage waterworks.The high concentrtion occurred for seasonality is former
Water, raw water preliminary sedimentation and sludge condensation processing are combined together, realize water factory's water outlet water under the high low turbidity difference operating mode of raw water
Matter is up to standard, and realizes the optimum organization treatment process of the concentration for producing sludge, dehydration and characteristic energy changes at the same time.
Background technology
Contain gas chromatography and inorganic matter in the water inlet of city tap-water factory, earth surface water source is easily flowed at the change of season
The factor change such as amount and water temperature, turbidity significantly raises in short-term for appearance, and water factory's process flow can not be tackled, while produces a large amount of raw
Waste water is produced as production accessory substance discharge technological process, surrounding enviroment are produced with larger pressure, becoming city tap-water factory must
The environment and social concern that must be solved.
At present, in the waterworks for taking high turbidity raw sewage generally simple preliminary sedimentation is used before routinely filtration treatment is precipitated
Technique tackles the high turbidity water quality of seasonal appearance, and produces contained sludge impurity in waste water and often treated as pollution sources,
By concentration, natural desiccation or mechanical dehydration, the contained production sludge in production waste water is set to be transported outward in the form of dry solid, to subtract
Few influence to environment.The major defect of above-mentioned technology is after working as ultra, and raw water of waterworks presents lasting relatively low turbid
When spending, preliminary sedimentation procedure can not play a role in treatment process, and produce the discharge of wastewater time and generally more concentrate, and processing is constructed
Thing floor space is larger, and operating cost is higher, and concentrated supernatant and dehydration filtrate are often relatively inaccessible to discharge standard, wherein largely
Organic matter becomes environmental pressure again as pollutant, it has also become the technical barrier of seasonal high turbidity raw sewage processing.
The content of the invention
The object of the present invention is to provide a kind of seasonal high turbid original sub-block technique, it is suitable for seasonal high turbidity raw sewage bar
Combined treatment process under part, the conventional art prejudice for overcoming water and sludge to handle respectively, preliminary sedimentation is handled, filtering is precipitated, is dirty
Mud thickening is combined together with Sewage treatment and characteristic energy changes function, is ensuring up to standard same for the treatment of process effluent quality
When, realize that the thickening of production spoil disposal water, Treatment of Sludge tail water qualified discharge and Organic substance in water are converted into bioenergy into one
Walk the function of recycling.
To achieve these goals, the technical scheme is that：A kind of seasonal high turbid original sub-block technique, its feature
After being that raw water is introduced into preliminary sedimentation concentration reuse tank preliminary sedimentation, water outlet is precipitated into sedimentation basin, after precipitation water outlet enters filter,
After water outlet is regulated and stored into clear water reserviors, pressurizeed by repumping house and be sent into city planting ductwork, the spoil disposal access balance of preliminary sedimentation concentration reuse tank
Pond is stored, and mud extraction is carried out dehydrating into dehydration machine room, deviates from dry mud outward transport disposal, and filtrate is discharged into concentration mass energy conversion
Pond.
According to an embodiment of the invention, when water factory's land used is well-to-do and construction fund is more nervous, depositing technology is contemplated that
Using the horizontal sedimentation tank or inclined-tube sedimentation tank that floor space is larger, horizontal sedimentation tank or inclined-tube sedimentation tank spoil disposal access spoil disposal pond
After be lifted into concentration basin concentration, concentration basin supernatant is discharged into concentration mass energy conversion pool, concentration basin spoil disposal and preliminary sedimentation concentration reuse
Pond spoil disposal is carried out dehydrating after counterbalance cell is regulated and stored into dehydration machine room in the lump.
After filter cell rinse waste water is discharged into blowoff basin, reuse is mixed with raw water after general lifting, concentration is discharged under emergency condition
Mass energy conversion pool.Concentration mass energy conversion pool carries out in-depth processing, part after receiving dehydration machine room filtrate and blowoff basin emergency drainage
Organic matter is converted into bioenergy recycling, remaining sludge carries out sludge drying processing；Concentration mass energy conversion pool filter liquor can be discharged into
Utilized after blowoff basin lifting as raw water, or up to standard be discharged into river water body.Usually raw water turbidity is less than during low turbidity operating mode
200NTU or silt content are less than 0.20 kg/m3, raw water can surmount preliminary sedimentation concentration reuse tank be directly entered sedimentation basin processing；Work as original
Water turbidity is more than 200NTU or silt content in 0.20 ~ 3.5kg/m3When, raw water should first pass through preliminary sedimentation concentration reuse tank preliminary sedimentation after again
Into sedimentation basin processing；When raw water silt content is more than 3.5kg/m3When, raw water should first be introduced into setting pot sand setting at dry point,
Water outlet concentrates reuse tank into sedimentation basin processing by preliminary sedimentation again.Increase potassium manganate before sediment outflow pond and preliminary sedimentation concentration reuse tank,
Add PAM before sediment outflow pond and preliminary sedimentation concentration reuse tank and in efficient sedimentation tank, alum is added before efficient sedimentation tank, before and after clear water reserviors
Chlorination, adds burgy after setting pot.
Sand setting is handled, precipitates filtering, sludge concentration and dewatering and Sewage treatment and characteristic energy changes function carries out group by the present invention
Close, be first combined together the Treatment for Reuse for producing waste water and preliminary sedimentation, be arranged on one as water-purifying process before sedimentation basin
Part, and the supernatant produced in wastewater treatment and dehydration filtrate are subjected to characteristic energy changes, the organic matter conversion of part is made a living
The thing energy.The different coprecipitation modes that the present invention is used according to treatment process, treatment process are classified, then according to different operations
Condition forms the complete process system of two sets for the treatment of process compositions with requiring.The advantages of technique, is to be adapted to different originals
Regimen condition and service requirement, water for drainage slurry technique and water-purifying process are combined together, at the same adapt to seasonal high concentrtion and
Usually low turbidity operating mode, will be easy to the concentration basin supernatant and dehydration filtrate of discharge beyond standards in production Waste water concentrating and dewatering process
After-treatment is carried out with concentration mass energy conversion pool, efficiently realizes water purification work using structures disposal ability to save floor occupying area
Skill standard water discharge is discharged and the useless Organic substance in water of production is converted into the effect that bioenergy further recycles.
