According to the results of the COD
detection in wastewater by the user using the COD analyzer, the reasons for the impact on the COD emission concentration are analyzed from the four aspects of man, machine, material and method, which may be due to the following reasons: 1. The operator's level is not enough. The operator is employed after rigorous training and has many years of experience in wastewater treatment. He can skillfully operate the entire set of wastewater treatment equipment and there are no operating errors. This is the secondary reason. 2. The dosage is not enough. The amount of industrial wastewater in the company is small, and batch treatment is adopted. According to our team, the amount of coagulant added each time is the same. If the concentration of wastewater to be treated in this batch is extremely high, insufficient coagulant reaction may occur. The discharge of wastewater without complete treatment may be the main reason for affecting the quality of effluent water. 3. The treatment process is not suitable. The company's wastewater treatment station adopts the air flotation process. The air flotation treatment process is simple, occupies a small area, has a small amount of coagulant dosage, and operates stably. It is more suitable for treating oily wastewater and is suitable for treating corporate wastewater. This is the secondary reason. 4. The processing flow is not perfect. The company's industrial wastewater first enters the air flotation tank after chemical coagulation treatment, and then is discharged into the outlet well after being treated by sand filtration. If the wastewater is not up to standard after treatment, it will also be directly discharged into the outlet well, which may cause excessive discharge. The lack of a necessary inspection link is the main reason. 5. The equipment is aging. The aging of wastewater treatment equipment will also affect the treatment effect of wastewater. At present, the company conducts routine maintenance work on the equipment every year. The equipment is in good condition and fully capable of processing the company's industrial wastewater, which is the secondary reason. After analyzing the causes, it was concluded that there are two main reasons affecting COD emission concentration: imperfect process and insufficient dosing amount. Therefore, we decided to renovate the wastewater treatment station, install a set of inspection equipment on the original equipment, and add a loop. If the water quality does not meet the standard, the wastewater will be re-treated through the loop to ensure that the COD concentration of the wastewater is discharged below the target value, thereby reducing Total COD emissions.
