Description
Technical field
The present invention relates to sewage treatment area, particularly relate at large-scale integrated sewage treating apparatus and sewage
Science and engineering skill.
Background technology
China's water pollution problem is the severeest at present.The particularly water pollution in city below two wires is suitable
Seriously.And these water pollutions arch-criminal be exactly large-scale polluter waters or administer halfway waters to
River course is drained, causes waters, river course to need to put into substantial amounts of manpower and materials and administer, and also can not get showing
The regulation effect write.Therefore, the sewage discharged for city below two wires carries out integrating improvement, and administers
Equipment investment and operation cost is low and sewage disposal is thorough, is only key point.
City below two wires the most concern is the Cost Problems of waste water control.And rely on current waste water control
Technology, if wanting to improve greatly the effect of waste water control on the basis of reducing cost, increases sewage disposal
The volume of equipment is one of good method.And to increase the volume of equipment, the building sides on ground will be increased
Long-pending.Although now many sewage disposal devices can be imbedded in underground, but the vertical earth's surface of equipment region, depend on
So cannot carry weight, and equipment easily corrodes, and the later stage is because sewage and mud after processing need equipment
Transport to ground, this adds increased the operation cost in later stage.The present invention is at the river course water surface of blowdown by equipment construction,
This just can solve problem above.

Detailed description of the invention
1 and Fig. 2 the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Setting artificial grid 2 in described grid 2, sewage introduces grid 2 well through sewage pipe 1, filters
Rear entrance sewage disposal system is uniformly processed.Grid 2 Main Function is to retain the bulk float in sewage and drift
Float, to ensure the safety of whole system plant equipment.Grid 2 is cleared up the most weekly once.
Being provided with liquid-level floater 4 and elevator pump 5 in described regulating reservoir 3, the sewage filtered through grid 2 enters
Entering in regulating reservoir 3, regulating reservoir 3 mainly stores sewage, and has the function of regulating pondage water quality, works as tune
Joint pond 3 liquid level reaches elevator pump 5 self-starting during the high level of liquid-level floater 4 setting, when liquid level drops to liquid level
Elevator pump 5 self-stopping technology during the low liquid level that ball float 4 is arranged.The Main Function of regulating reservoir 3 has 2 points: one is regulation
The water yield, buffering production line draining peak amount, provide stable service condition for follow-up sewage disposal system；Two is to examine
Considering and there are differences because of sequential difference to the pollutant levels contained by draining, equilibrium enters follow-up sewage disposal system
Sewage quality, eases off the pressure for subsequent treatment.
Described anaerobic pond 7 is built with elastic filler 14, and the boosted pump of sewage 5 carries to anaerobic pond 7,
Anaerobe, with elastic filler 14 as carrier, carries out anaerobic biodegradation, is divided by macromole complexity Organic substance
Solution becomes the labile material of little molecule to process for easy-to-keep biological provides support.Anaerobic bio-treated is as utilizing anaerobism
Property microorganism metabolic characteristic, provide under conditions of external source energy, to be reduced Organic substance as by hydrogen not needing
Body, has the methane gas of energy value simultaneously.Anaerobic biotreatment method is applicable not only to the organic dirt of high concentration
Water, water inlet BOD maximum concentration is up to tens thousand of milligrams per liter, it is possible to be applicable to low-concentration organic wastewater, such as city
Sewage etc..Anaerobic bio-treated process energy consumption is low；Organic volumetric loading is high, generally 5～10kgCOD/m3.d；
Surplus sludge volume is few；Anaerobe is low to nutritional need, resistance to poison is strong, degradable organic matter molecular mass high；Resistance to
Impact load ability is strong；The biogas of output is a kind of clean energy resource.
Hanging with elastic filler 14 in described contact-oxidation pool 10, sewage is flowed into through anaerobic pond overfall 8
In contact-oxidation pool 10, total residence time is more than 4 hours, and in sewage, major part Organic substance is dropped at this
Solving and purify, aerobic microbiological is with filler as carrier, and utilizing the Organic substance in sewage is food, by sewage
Organic substance resolves into inorganic salts and water, thus reaches the purpose purified.Contact-oxidation pool 10 air is by blower fan
30 provide.Using novel elastic filler 14 in pond, this filling surface is long-pending big, and service life is long, easy to be filmed,
Corrosion-resistant.Using rotary mixing aerator 11 at the bottom of pond, the rate of transform making dissolved oxygen is high, has lightweight, no simultaneously
Aging, be not easily blocked, service life the advantage such as length.Contact-oxidation pool 10 steam-water ratio is at 12:1, at biochemistry
In pond, interior circulation, contacts with the biomembrane on filler fully, reaches under conditions of blower fan 30 oxygen supply
To the rapid Degradation of Organic substance.Biological Contact Oxidation Process be a kind of between activated sludge process and biofilter it
Between bio membrane process, be characterized in arranging filler in pond, aeration at the bottom of pond carries out oxygenation to sewage, and makes
In cell body, sewage is in flow regime, to ensure that sewage is fully contacted with the filler in sewage, it is to avoid catalytic oxidation
Pond 10 exists sewage and contacts the defect of inequality with filler.Institute of Micro-biology is aerobic to be supplied by blast aeration, biological
After film grows to certain thickness, the microbes of filler wall carries out anaerobic metabolism because of anoxia, the gas of generation and
The souring that aeration is formed can cause biomembranous coming off, and promotes the growth of neoplasm film, now, comes off
Biomembrane will be flowed in sedimentation tank 18 by the overfall 15 of contact-oxidation pool with water outlet.
It is provided with reflux pump 20 and sludge pump 22 in described sedimentation tank 18, contact-oxidation pool 10 water outlet contains
Having a large amount of activated sludge, these mud are flowed in sedimentation tank 18 along with sewage, have under the effect of swash plate 19
The mud having good settling property can be good at carrying out mud-water separation, and isolated water up to standard is by opening draining
Electromagnetic valve 24 on mouth 23 is drained in river course 29 by drain pipe 25.In order to micro-in keeping contact-oxidation pool 10
Stable and the sludge aging impact on system of Biomass, a part of mud drains into contact oxygen by reflux pump 20
Changing in pond 10, another part drains in sludge-tank 27 by sludge pump 22, when concentrating full dirt in sludge-tank 27
During mud, mud can be discharged by sludge-tank manhole 28 by external device.
Described anaerobic pond manhole 9, contact-oxidation pool manhole 16, sedimentation tank manhole 26, sludge-tank manhole
28 are easy for staff enters each pond and safeguards equipment and keep in repair.
Described canyon 17 is internal has electric control gear, described electric control gear divide manual operation and are automatically brought into operation
Two parts.
With a certain engineering waste water control as background, the present invention is to the engineering index before and after sewage disposal such as
