Technical field
The invention belongs to biochemical processing fields, and in particular to a kind of improvement biochemistry pool mixing effect method.
Background technology
Currently, method used in each sewage plant biochemistry pool is impeller power frequency operation, and can not according in biochemistry pool not
Change the running frequency of impeller with the sludge concentration of depth.Therefore, it is impossible to ensure that the sludge in biochemistry pool is uniformly mixed journey
Degree, in fact it could happen that sludge sinks to the bottom lamination.
Invention content
The present invention is directed to the situation of the prior art, overcomes drawbacks described above, provides a kind of improvement biochemistry pool mixing effect method.
The present invention uses following technical scheme, the improvement biochemistry pool mixing effect method to include the following steps：
Step S1：Obtain the sludge concentration of biochemistry pool predetermined depth successively according to default detection ordering；
Step S2：Using the sludge concentration of biochemistry pool current depth as the specified rate R (t) of control unit；
Step S3：By amount R (t) given herein above and feedback quantity Y (t) synthesis departure E (t)；
Step S4：By above-mentioned departure E (t) input control unit, and by control unit output controlled quentity controlled variable is adjusted through PID
U(t)；
Step S5：Above-mentioned controlled quentity controlled variable U (t) is inputted into impeller to control impeller converting operation；
Step S6：Counter give the feedback quantity Y (t) that impeller exports to control unit.
According to above-mentioned technical proposal, in step S4, controlled quentity controlled variable U (t) is embodied as the running frequency of impeller.
According to above-mentioned technical proposal, described control unit includes proportioner, differentiator and integrator.
Improvement biochemistry pool mixing effect method disclosed by the invention, advantage are, by each pre- depthkeeping of biochemistry pool
Input parameter of the sludge concentration of degree as control system is adjusted to obtain accurate impeller running frequency by PID closed loops, be made
Impeller is obtained according to above-mentioned running frequency converting operation.While promoting in biochemistry pool sludge to be uniformly mixed, it is effectively reduced consumption
Electricity, to reduce the station-service electricity of sewage plant.
