Description
Technical field
The invention belongs to sewage treatment area, a kind of biological oxidation system of Aerobic biological process method is specifically related to.
Background technology
Activated sludge process is a kind of Aerobic biological process method of sewage, by the Clarke of Britain（Clark）And Gage
（Gage）About invented and applied in Mancunian Lao Lunsi sewage experiment station in 1913.Nowadays, activated sludge process and its spread out
Raw improved process is the most widely used method of Treating Municipal Sewage.It can remove deliquescent and colloidal state from sewage
Biochemical organic matter and can be by the suspended solid of activated sludge absorption and some other material, while can also remove a part of phosphorus
Element and nitrogen, are the general designations of the various methods for the microorganism (micro-organism) that biological wastewater treatment is suspended in water.
Typical activated sludge process is made up of aeration tank, sedimentation basin, sludge recirculation system and excess sludge removal system.
Sewage and the activated sludge of backflow enter aeration tank and form mixed liquor together.The compressed air sent from air compressor station, leads to
The air-diffuser for being laid on aeration tank bottom is crossed, to enter in the form of tiny bubble in sewage, it is therefore an objective to increase in sewage
Dissolved oxygen content, also make mixed liquor be in vigorous agitation state, in suspended state.Dissolved oxygen, activated sludge and sewage are mutual
Mix, fully contact, activated sludge reaction is normally carried out.
The ratio between organic matter and microorganism claim mud load rate (F:M).The metabolism depth of its influence process and the sedimentation of sludge
Performance, also influences the stability and capital cost of operation.Mud load rate is lower, and the running and comparing of process is easy, treatment effeciency
More stable, surplus sludge volume is fewer, but capital construction and operating cost typically will height.The load of conventional activated sludge process
Rate is often between 0.15~0.3 kilogram of BOD/ kilograms of sludge.High Load Rate activated sludge process use more than 1, sludge back flow quantity and
Air capacity can greatly reduce, and save expense, but BOD clearances are reduced to 60~70%, therefore also referred to as modification activated sludge
Method, the occasion for only needing to medium degree for the treatment of.
Existing biology aerobic oxidative system, it is up to standard to ensure, typically it is underrun, is partly designed with high load capacity fortune
Row section, need to increase filler, and Wind Volume aeration, can increase equipment investment and a large amount of energy consumptions, and exist after long period operation,
The problem for the treatment of effeciency is reduced, mainly sludge are largely adsorbed after organic matter, it is impossible to degraded in time, while microorganism was rised in value
It hurry up, biomembrane updates frequent, cause internal sludge blanket anoxic aging, organic matter release phenomenon, and then influence effluent quality again.
The content of the invention
Goal of the invention：Present invention aims at can lift microbial metabolism there is provided one kind in view of the shortcomings of the prior art
Speed, and the high load capacity biology aerobic oxidative system being aerated without Wind Volume.
Technical scheme：High load capacity biology aerobic oxidative system of the present invention, including former pond and high load capacity oxidation pond, institute
State and gas dissolver is additionally provided between former pond and the high load capacity oxidation pond, the gas dissolver is provided with water inlet, gas feed
And water out, the water inlet connected with the former pond, and the gas feed is connected with air compressor, and the gas dissolver will
The air that the gas feed is passed through is dissolved under pressure state in the water that the water inlet is passed through, and forms dissolved air water；The water
Export and connected with the release being arranged in the high load capacity oxidation pond, the dissolved air water in gas dissolver is passed through height by the release
In load oxidation pond, reacted with the activated sludge in the high load capacity oxidation pond.
Further preferably technical scheme is to be additionally provided with agitating device in the high load capacity oxidation pond to the present invention, described
Release is arranged on the bottom of pond of the high load capacity oxidation pond.
Preferably, the delivery port of the former pond is connected by water pump with the water inlet of the gas dissolver.
Preferably, the water inlet of the former pond is connected with upper level sewage disposal system.
Preferably, described upper level sewage disposal system is that sewage SS removes system.
Preferably, the release is aerosol release.
Preferably, the release is multiple, and multiple releases are arranged in the bottom of pond of the high load capacity oxidation pond, and divide
Do not connected with the gas dissolver, the dissolved air water in the gas dissolver is discharged into the high load capacity oxidation pond.
The present invention principle be：Biology aerobic oxidation is broadly divided into organic matter absorption, organic matter storage metabolism, needs simultaneously
Sufficient oxygen supply.Organic matter is better to be released with mud, gas, and the function of all microorganism individuals can be more fully utilized,
And strengthen its metabolic rate.In the present invention, raw water is pumped into gas dissolver by water pump and is pre-mixed with air, by gas dissolver
Seal-off pressure, by air compression enter water in, realize that water is fully contacted with the first step of gas, the raw water after molten gas is through release
Release, into bio-oxidation pond, completes the utilization rate for being sufficiently mixed contact, improving air of water, gas, mud, improves micro- in sludge
Biological effective metabolic rate.
Beneficial effect：（1）Former water and air is pre-mixed in the present invention, by release by dissolved air water to oxidation
Discharged in pond, it is ensured that oxidation pool inner water, gas, mud are sufficiently mixed contact, complete high load capacity active sludge oxidation process, improve sky
The utilization rate of gas, is improved in effective metabolic rate of microorganism in sludge, also, whole reaction without Wind Volume aeration, Jin Erda
To reducing investment outlay, the purpose of energy consumption is reduced；
（2）Agitating device is additionally provided with the present invention in high load capacity oxidation pond, release is arranged on the high load capacity oxidation pond
