Description
Technical field：
The invention belongs to environmental project technical field of sewage, anti-particularly to a kind of multi-mode for sewage disposal
Ying Chi, the process that can be used for sanitary sewage and the industrial organic waste water of Wastewater Treated by Activated Sludge Process can be adopted.
Background technology：
Water resources in china occupancy volume per person is few, and spatial distribution is unbalanced.With Chinese Urbanization's, industrialized acceleration, water
The demand gap of resource also increasingly increases.Under such background, sewage treatment industry becomes new industry, current and aquatic from the beginning
Product, water supply, draining, Treated sewage reusing industry are in status of equal importance.
In recent years, wastewater treatment in China industry is advanced by leaps and bounds, and overall development is in the fast-growing period, is mainly manifested in sewage
The aspects such as disposal ability is expanded rapidly, wastewater treatment rate steadily improves, sewage load rapid growth.End in by the end of June, 2016,
National the planned city, county (without other organic towns) add up to build up sewage treatment plant 3934, and sewage treatment capacity 1.69 hundred million is stood
Square rice/day.
The sewage treatment plant's majority building up adopts Wastewater Treated by Activated Sludge Process, and Activated Sludge Process more ripe at present is divided into
Three series：(1) oxidation ditch series；(2) batch-type reaction tank (SBR)；(3)A2O series.
Oxidation ditch process can be divided into card Losail oxidation ditch, Orbal oxidation ditch, double channel type oxidation channel, three working position
Deng, be a kind of modified of activated sludge process, there is dephosphorization denitrogenation function, its reaction tank be closing irrigation canals and ditches, waste water and activity
The mixed liquor of mud constantly circulates wherein, therefore oxidation ditch also known as " continuous cyclic aeration method ".Such reaction tank lack
Point is that pond is deeply shallower, and floor space is larger, and surface mechanical aeration is larger to surrounding environment influence, and municipal sewage temperature is low in the winter time
Regional denitrification effect is poor.
The operation operation in the key reaction pond of batch-type reaction tank (SBR) is by inflow, reaction, precipitation, discharges and idle
Five operation compositions.Sewage in reaction tank by sequence, intermittently enter each reaction process, the operation in each sbr reactor pond
Operation is also arrangement intermittent duty in order in time.Before flowing into operation and implementing, the sewage after idle operation process is
Through discharge, in reaction tank remaining the active sludge intermixture of high concentration.When sewage injection flows into, reaction tank can play tune
The effect in section pond, if carrying out aeration can obtain preaeration effect, also can make mud regenerate, recovering its activity.Reaction process
It is the topmost procedure of SBR technique.After sewage injection reaches predetermined volume, operation can be started, such as removal BOD,
Nitrification, the absorption of phosphorus, and denitrification etc..In spoil disposal operation, stop aeration and stirring, so that mixed liquor is remained static, live
Property mud is separated from water, and is equivalent to the effect of secondary sedimentation tank.Supernatant after precipitation, as processing Chinese effluent, precipitates
Mud stay in reaction tank as kind of mud, play the effect of returned sludge.In idle operation, after processing Chinese effluent, reaction
Pond stays cool, and waits the next operation cycle.The subject matter that batch-type reaction tank (SBR) exists is：Complex operation,
Automatic control is had high demands；In addition to determine apparatus utilization rate in itself low for its technological process.
A2The reaction tank of O is made up of anaerobism, anoxic and aerobic three sections, and flora is mainly by nitrifier and denitrifying bacterium, poly- phosphorus
Bacterium etc. forms.In aerobic section, will become a mandarin middle organic nitrogen and ammonia nitrogen of nitrobacteria changes into nitrate by biological nitration effect；?
Anoxic section, the nitrate that interior backflow is brought into is passed through biological denitrification by denitrifying bacteria, changes into nitrogen and escapes into air
In, thus reaching the purpose of denitrogenation；In anaerobism section, polyP bacteria discharges phosphorus, and absorbs the degradable organic matter such as lower fatty acid；
And in aerobic section, polyP bacteria excess absorbs phosphorus, and by the discharge of excess sludge, phosphorus is removed.Because denitrogenation and dephosphorization are external
The requirement of portion's environmental condition is conflicting, and denitrogenation requirement organic loading is relatively low, and sludge age is longer, and dephosphorization requires organic bearing
Lotus is higher, and sludge age is shorter, is often difficult to balance；PolyP bacteria discharges phosphorus under anaerobic state and the denitrification of anoxic zone generation is past
Compete toward being formed in carbon source；Generally, for the more rich situation of carbon source, reliable and stable, the dephosphorization of operating of this reaction tank
Denitrogenation degree is high, water outlet high treating effect.
