The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the conventional chemical sewage treatment process is as follows:
the sewage generated in the workshop 1 is discharged into a sewage adjusting tank 4 through a self-flowing pipe 2 or a drainage pump 3, is pumped into a first stirring tank 7 through a first water suction pump 11, adding a flocculating agent A into the sewage in the first stirring tank 7, stirring, after the flocculation in the first stirring tank 7 is finished, the sewage after the first-step flocculation reaction in the first stirring tank 7 is pumped into a second stirring tank 8 by a second water pump 12, adding a flocculating agent B into the sewage in the second stirring tank 8, stirring, after the flocculation reaction in the second stirring tank 8 is finished, the sewage after the two-step flocculation reaction is discharged into the sewage sedimentation tank 5 through the sewage discharge pipeline 17 for floccule sedimentation, finally, clear water on the upper layer in the sewage sedimentation tank 5 is pumped and discharged to a specified discharge port, and the residual sludge in the sewage sedimentation tank 5 is pumped out through the sludge pump 6.
In the above conventional flow, the amounts of the flocculants added to the first and second stirring tanks 7 and 8 are completely added according to past experience, and if the concentration of the pollutants in the sewage discharged from the workshop 1 changes, the amounts of the flocculants added to the first and second stirring tanks 7 and 8 need to be manually observed and analyzed to select whether the amount of the flocculants is increased or the amount of the flocculants is decreased. The accuracy of the judgment is completely related to the experience of technicians, and the scale is difficult to grasp. Moreover, it is difficult to judge whether the flocculating agent is used sufficiently or not in the stirring step by experience. If the amount of the flocculant is insufficient and the sewage is already discharged into the sewage settling tank 5, it is not reasonable to additionally add the flocculant to the sewage settling tank 5. If the addition of a significant excess of flocculant is made to ensure sufficient flocculation in the agitation stage, significant waste of flocculant will result.
For the above reasons, the present application proposes the following improvements.
The first embodiment of the sewage treatment chemical dosage control system based on image recognition is described with reference to fig. 2:

The image analysis process mainly analyzes and calculates the clear image and the floccule proportion of the water body after the reaction of adding the flocculating agent, and the higher the cleaning degree is and the higher the density of the identifiable floccule is, the more sufficient the flocculation reaction is. Therefore, a standard reference value needs to be set during image analysis, and whether the addition amount of the flocculating agent is enough or not is judged by calculating and comparing the image information acquired in real time. Namely, when the analysis result of the sewage photo taken above the first buffer tank 9 reaches the reference value, the addition amount of the flocculant is kept unchanged during the period. When the analysis result is lower than the reference value, the addition amount of the flocculating agent is increased in the period.
