The present invention disclosed an aeration device based on the A1‑A2‑O process, involving the field of wastewater treatment technology.Including a centrifugal pump component, there are several mixed rooms on the sides of the centrifugal pump component. The surface of several mixed rooms is connected to a diversion pipe. One end of the diversion pipe is connected to a mixed pipe.There are three -way pipe connecting one end of the mixed pipe. One end of the three -way pipe is connected to the trachea. One end of the three -way pipe is connected to the material tube. The surface of the centrifugal pump component is fixed with a control box. The control box is equipped with a solubility sensor. The internal fixation of the control box is fixed.Processor, power module and AD converter.The present invention is detected by the dissolved oxygen in the water through the control box with the control box, and controls the intake and salt control of the pipeline of the centrifugal pump component, pump pump and solenoid valve to achieve automated control in the range of dissolved oxygen.The stability and processing efficiency of the A1‑A2艺 0 process sewage treatment system reduced the manual workload.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to an aeration device based on the A1-A2-O process. Background technique [0002] The concentration of pollutants in coke wastewater is high, which is a typical refractory organic wastewater. Due to the complex organic components and high ammonia content in coking wastewater, it is difficult to meet the treatment standards. At present, the treatment of coke wastewater is more difficult. A good way is to use the A1-A2-0 process. The A1-A2-0 process can not only remove phenol, fluorine and other pollutants in wastewater well, but also deaminate macromolecular organic nitrogen during the acid production stage, which can better remove organic nitrogen and make it meet the new discharge standard requirements. [0003] In the A1-A2-0 process of coke wastewater treatment, the pretreated wastewater is sequentially subjected to three processes of anaerobic, anoxic and aerobic....
