Automatically-operated intelligent SBR (sequencing batch reactor) sewage treatment device and method

Abstract

The invention relates to the related field of sewage treatment, in particular to an intelligent SBR sewage treatment device and method capable of achieving automatic operation, an L2SBR controller achieves automatic control with the effluent quality as the target, and on the basis of common automatic control, automatic control is achieved. The operation time of each device is flexibly controlled according to the changes of the liquid level, the dissolved oxygen concentration, the oxidation-reduction potential value, the concentration value of suspended solids in a mixed solution and the pH value in a sewage pool, and the operation of various electromagnetic valves is matched, so that the operation efficiency of the devices is improved, and the purposes of energy conservation and consumption reduction are achieved; meanwhile, the device can be suitable for almost all SBR sewage treatment units in a sewage treatment plant or a sewage treatment station, and in the transformation of the sewage treatment plant or the sewage treatment station, if no control system exists in the original sewage treatment process, the L2SBR controller can be added, and a corresponding monitoring sensor can be configured, so that the effect of automatic control is achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an automatically operated intelligent SBR sewage treatment device and method. Background technique [0002] With the continuous development of human society, domestic and production water consumption has increased sharply, and at the same time it has brought serious water pollution problems. Sewage treatment is particularly important. With extensive and in-depth research on the material reaction and purification mechanism in SBR, the sewage treatment industry has emerged Various derivative treatment processes, but the traditional SBR process is still widely used. With the rapid development of the electronic computer industry, the hardware equipment and software technology of automatic monitoring and control are also gradually put into the SBR process. The SBR treatment effect is continuously improved, and the process Design and operation management are increasingly scientific. ...

AI Technical Summary

Problems solved by technology

[0005] The control and management of SBR by traditional fixed time series is simple, but unilaterally adjusting the time configuration in the cycle cannot completely solve the operating conditions caused by seasonal changes, less sewage volume, and changes in water quality concentration. Dissolved oxygen in SBR sewage treatment units Failure to replenish in time will cause the microorganisms in the reactor to fail to react normally, and eventually the effluent will still fail to meet the standard

At the same time, in the aeration stage, the blower usually maintains a certain air supply volume and operates continuously, and the air supply volume cannot be adjusted in real time according to the aeration oxygen demand, which is not conducive to improving the process capacity, greatly reducing work efficiency, and causing great damage. Energy waste, difficult to achieve energy saving
