Description
Technical field
The present invention relates to a kind of automatic monitoring device of active sludge multiparameter.
Background technology
At present, municipal sewage plant 80% all adopts the active sludge treatment scheme both at home and abroad.Therefore, monitor the mass effect of wastewater treatment, at first should monitor the characteristic index of active sludge in the sewage: SV, MLSS, SVI, SDI.By the manual inspection technological approaches of current international norm, can't realize the technical goal of continuous monitoring round the clock.
In the operational management of Wastewater Treated by Activated Sludge Process process and in every test of activated sludge purification reaction, as the activated sludge concentration index and widely used be the number percent (SV of active sludge intermixture concentration of suspension (MLSS) and 30min subsidence volumn
30).
Mud MLSS is an important parameters very, on the engineering often with MLSS as the index of metering active sludge microorganism amount indirectly, it is an important control parameter of operational management.If MLSS exceeds particular range, must manage to make it to recover normal, otherwise certainly will cause the biological treatment system effluent quality to change, even the various discharge indexs that cause comprising suspension exceed standard.In addition,, the sludge volume index of mixed liquor be can also monitor, thereby the settling character and the activity of active sludge and other biological suspending liquid understood by measuring MLSS.
The mensuration of SV value can be used for monitoring the performance of active sludge intermixture.Usually instruct the operation of activated Sludge System with SV.If when the cohesion of active sludge, when settling property is good, the size of SV can reflect that (international standard is 2～4g/L) to the normal sludge quantity that moves of activated sludge tank.So in a lot of Sewage Plant, often control the discharge capacity of excess sludge with SV.
Sludge index SVI can reflect the quality of activated sludge settling property more accurately.Relatively SV has got rid of the influence of sludge concentration to settling volume in the notion of SVI, can reflect the loosening degree of active sludge and cohesion, sedimentation function preferably, is to judge that sludge settling concentrates a parameter commonly used of performance.
At present, the measurement of MLSS is also adopted the gravimetric analysis method of time and effort consuming both at home and abroad, often will be spent several hrs and just can detect the result.The optics turbidity detecting head of external import, price is more expensive, and the sensitivity religion is low, and it can only judge MLSS roughly, and it misses by a mile, and photoelectric colorimetry only can detect the MLSS single index in addition.In addition, SV and SVI are not also formed the more complete automatic monitoring route of a cover both at home and abroad, the monitoring of these two indexs is all undertaken by manual type, therefore the processing procedure that turns round continuously round the clock can't realize high-level efficiency, one day triple shift waste of manpower resource, it is untimely to cause information to compile automatically, causes the backwardness of wastewater treatment robotization mechanism.So instrument detecting is imperative fast.
Summary of the invention
The objective of the invention is: a kind of automatic monitoring device of active sludge multiparameter is provided, for sewage disposal system provides a kind of intelligent multiparameter device for monitoring simultaneously to the detection of the every index of active sludge, human resources and waste of time that labor measurement brings have been exempted, and improve the accuracy that detects data, can be widely used in the sewage disposal system.
