Description
Technical field
The present invention relates to sewage treatment technology field, a kind of specifically novel wisdom aeration.
Background technique
Requirement with country to environmental protection is increasingly stringenter, and Chinese sewage treatment plant is also more and more.Heavy civil is dirty
Water factory just has more than 6000 at present, and industrial is more.So more sewage plants is almost and builds up in 10 years, and relevant
Designing technique and operational management skill relatively lag behind, and the talent of operational management does not catch up with yet, and most sewage plants are in extensive
Formula controlled state.Aerating system energy consumption accounts for 60% or so of entire sewage plant entirety energy consumption, and not only only a large amount of electric energy is unrestrained
Take, and aeration quantity can not carry out dynamic adjustment according to the water and water quality of water inlet, water outlet is also not easy stably reaching standard, often
Also environmental fines are caused.In face of such status, our company is according to the accumulation of more than 10 years blast aeration technologies and numerous projects
Experience proposes " wisdom aeration ", it would be desirable to well solve operation and the management pain spot of existing sewage plant biochemistry pool.
Also there is the company for promoting accurate aeration technology in the market, but there is apparent defects for their technology: excessive
Ground relies on in-line meter, flowmeter and accurate control valve.These in-line meters can often drift about as time goes by, that
Accuracy will be lost, stable operation can be also unable in " accurate aeration " scheme read on these meter contacts by establishing；Again
It exactly needs to establish complicated model, sets a model in a sewage plant in advance, one is done to model over time
Fixed optimization, but it is uncomfortable once such model after Effluent criteria has changed or flooding parameter varies widely
With, that is, model is with certain scope of application.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, one kind is provided and needs not rely on in-line meter, based on big
The accurate intelligent aeration method of data.
To achieve the goals above, design a kind of novel accurate aeration method, comprising: one be placed in it is molten in the middle part of aeration tank
Solve oxygen measuring point；One template sedimentation basin being discharged for filling aerobic tank, which is equipped with inclined plate or inclined tube, for increasing
Add desilting area；
Step 1: obtaining sewage plant influent quality parameter, biochemistry pool parameter, simulation inclined plate or inclined-tube sedimentation tank water outlet parameter and dirt
Water factory's effluent quality parameter is saved in database；
Step 2: simulation inclined plate or inclined-tube sedimentation tank water outlet actual parameter and setting value are compared,
A, for actual parameter in ± 0.1 range of setting value, preservation rotation speed of fan is constant, and sewage plant influent quality at this time is joined
Number, biochemistry pool parameter, fan operation parameter, simulation inclined plate or inclined-tube sedimentation tank water outlet parameter and sewage effluents water quality parameter are protected
It is stored to database；
B, actual parameter > setting value+0.1 increases rotation speed of fan automatically, and record simulation inclined plate or inclined tube export water quality parameter, then
Relationship between secondary relatively simulation inclined plate or inclined-tube sedimentation tank water outlet actual parameter and setting value；
C, actual parameter < setting value -0.1 reduces rotation speed of fan automatically, and record simulation inclined plate or inclined tube export water quality parameter, then
Relationship between secondary relatively simulation inclined plate or inclined-tube sedimentation tank water outlet actual parameter and setting value；
Step 3: database finds similar influent quality situation to control fan parameter；
Step 4: system compares simulation inclined plate or inclined-tube sedimentation tank water outlet parameter and sewage effluents water quality parameter automatically, automatically
The setting value of amendment simulation inclined plate or inclined-tube sedimentation tank water outlet parameter, guarantees sewage effluents water quality reaching standard.
DO determination probe is placed in the middle part of the aeration tank, which can store determination data and be uploaded in real time
In PLC control cabinet.
The template sedimentation basin has an aerobic tank sewage access port, connect with aerobic tank, sewage and dirt after measurement
Mud is discharged into biochemistry pool.
The template sedimentation basin has a supernatant outlet, and exit increases detection sewage disposal device, and will measure
Data are transmitted to PLC control cabinet.
The template sedimentation basin has a heavy bucket region, and a mud discharging mouth.
The template sedimentation basin is placed in after the aerobic tank in sewage treatment process, and aerobic tank herein refers to sewage
The biochemical reactor being aerated in treatment process, including it is aerobic in treatment tank, and conventional activated sludge process
Pond.
The template sedimentation basin is to be arranged in parallel with the secondary settling tank in sewage treatment process.
After the template sedimentation basin supernatant outlet detection device data detected are transmitted to PLC control cabinet, control
Cabinet adjusts the air quantity of aerobic tank Aeration fan further according to program, to realize the accurate aeration of blower.
The present invention compared with the existing technology, the advantage is that:
1., can be more clearly from because the oxygen supply of aeration tank end often has more than needed, the Forward if measurement that will solve oxygen is popped one's head in
Solution dissolved oxygen situation into aerobic tank can allow system program timely and effectively to adjust aeration situation, be truly realized " essence
Really aeration ".
2. aerobic tank data measured is with secondary clarifier effluent mouth data measured, there are 3-4 hours even greater time lags.
By providing a template sedimentation basin, increase inclined tube or inclined plate in the template sedimentation basin.Because the template precipitates pool volume very
It is small, so that the time lag between aerobic tank data measured and simulation sedimentation basin shorten to 20-30 minute or even shorter, thus
The defect that data delay can be eliminated, substantially increases aerobic tank Fan Regulation air quantity and regulates oxygen pond dissolved oxygen content in turn
Accuracy.
3. being used to judge trend with a small amount of in-line meter, data are read after long-time, not shadow drift occurs
Trend judgement is rung, system can still operate normally.The foundation for teaching system judgement by big data simultaneously, can not only save
About a large amount of energy consumptions, and it is discharged more stably reaching standard.Not only mint of money has been saved, but also has reduced environmental protection punishment risk, moreover it is possible to subtracted
Few dependence to operations staff.
