Description
Technical field
The utility model belongs to water and sewage treatment field, and in particular to a kind of resistance measurement system of biological activated carbon and
Test method.The method introduced in this utility model can quickly judge the resistance of drinking water or the used active carbon of sewage treatment
Power can provide Technical Reference for the operation and maintenance of activated carbon filter.
Background technique
Biological activated carbon (BAC) in drinking water treatment and sewage treatment using more and more.In drinking water treatment,
With the use in conjunction such as ozone, the quality of drinking water can be improved as advanced treatment process in BAC.Active carbon is multi-purpose in sewage treatment
In the processing of recycled water, secondary effluent can further decrease the pollutants such as ammonia nitrogen, organic matter after BAC is handled, and reach river benefit
The standard of water or landscape water.Therefore, importance of the BAC in drinking water and sewage treatment also increasingly increases.BAC is in addition to can be with
Organic matter, ammonia nitrogen, the particulate matter etc. in water removal are removed, to the pollutants such as personal care articles and drug and disinfection by-products formation potential
There is good removal to act on.Moreover, effect of the biological activated carbon by microorganism in active carbon, active carbon can be maintained to ammonia nitrogen and
The removal effect of the pollutants such as organic matter, therefore the service life of active carbon is very long.The water factory of actual motion and sewage plant experience
Showing that the active carbon of certain water factories uses the time is more than 10 years, but still can maintain stable treatment effect.
Although active carbon can be used for a long time, with the use of active carbon, active carbon will appear aging phenomenon,
Being embodied in active carbon, gradually aging, strength reduction, Particle Breakage, partial size become smaller.Property becomes after active carbon aging
Change, and then the operation that will lead to filter tank deviates design parameter, keeps filter tank operation impacted.Such as, as runing time extends, filter tank
Filtration resistance increases, and the fine grained active carbon for being accumulated in filter tank upper layer makes filter tank become surface filtration mode, reduces active carbon filtration
The pollutant carrying capacity in pond and the recoil time for shortening filter tank.
There is no the agings for active carbon to be designed in Practical Project at present, in order to cope with active carbon aging to activity
The influence of carbon filtering pool strainability, water factory, which generallys use waiting problem, to be occurred, then uses engineering means solution to the problem,
Or by the way of solving when groping, the operating parameter in filter tank is constantly adjusted.This considerably increases the operation risks of water factory
And operating cost.
According to Kozney-Karman formula it is found that particle diameter of filter medium is the primary parameter for influencing activated carbon filter filtration resistance.
Strength reduction after active carbon aging, active carbon particle phase mutual friction in backwash process can make Particle Breakage, and partial size reduces.This
It is the main reason for causing the increase of filter resistance, filter tank to be unable to operate normally.Due to the national standard measurement side of activated carbon particle size
Method is all comparatively laborious, and needs corresponding equipment, and measured parameter, which also needs to carry out model calculating, can just obtain resistance, belongs to
The indirect measurement of resistance, and the factors such as active carbon internal voids are not considered, it is easy to cause biggish deviation.Therefore, how fastly
Speed, the filtration resistance in easy direct filter tank, are of great significance to instructing filter tank to run.Pass through the filtering in periodic detection filter tank
On the one hand resistance can accumulate data in conjunction with partial size and intensive parameter, establish database, the use of prediction active carbon as early as possible
Service life；On the other hand filter tank operating parameter can also be adjusted in time according to testing result, such as improves backwashing strength, discharge part is small
Partial size charcoal particle reduces resistance.But through retrieving, there has been no relevant device and method to be related to the survey of BAC filtration resistance at present
Fixed or even relevant research is also rarely reported.
For example, prior art CN202393687U, water supply network pipe'resistance coefficient test device, including pipe-line system,
Pressure test module, flow rate test module and control system, the pipe-line system include main leg, branch pipeline section, preceding fire hydrant, in
Fire hydrant, rear fire hydrant, the pressure test module include pressure sensor, the pressure sensor be mounted on before fire hydrant and
On middle fire hydrant, it is equipped with rear control valve on the main leg, preceding control valve, the pressure are equipped on the branch pipeline section
Test module is connected to the control system by an interface convertor, and the flow rate test module includes ultrasonic flowmeter,
The ultrasonic flowmeter is mounted on rear fire hydrant, is equipped with a set of intelligence record system inside the control system described.This skill
Art measure object is the resistance coefficient of pipeline, and the resistance of pipeline is mainly derived from the boundary layer between fluid and tube wall, boundary layer
The interior biggish velocity gradient of fluid produces shearing force, and then shows as the frictional force of fluid resistance and pipeline.But this system without
The test of method realization active carbon resistance.Because in active carbon resistance measurement, exactly needing to shield the influence of pipe resistance bring.It is living
Property charcoal resistance measurement in, the parameter that needs to acquire is the resistance of active carbon, and therefore, when measurement needs resistance caused by pipeline to the greatest extent may be used
Can be small, reduce its influence to active carbon resistance measurement.Even if pipe resistance is very low, it is also desirable to utilize the step in preceding method
2, the resistance measurement of blank system is carried out, to guarantee the accuracy of active carbon resistance measurement.In addition, this system measurement is desirable
Using test device, fire hydrant is dismounted at the scene, and need higher flow rate of water flow, can just be detected between two fire hydrants
To pressure drop.It reduce the feasibilities of test.
The filtration resistance for how fast and accurately measuring the filter tank BAC, instructs the operation in filter tank to have important meaning to actual production
Justice.It is also possible to carry out relevant research using the drag data obtained, designing institute is helped to improve the design ginseng in the filter tank BAC
Number, improves the design specification of current BAC technique.Therefore, a kind of system and method for measuring active carbon resistance of utility model, become
Current urgent problem.
