The active sludge biological treatment method is relatively common in industrial wastewater treatment. The process control of this method mainly involves the control of dissolved oxygen content in the aeration tank, the control of sludge return flow, and the control of excess sludge discharge. All these controls are inseparable from the detection of dissolved oxygen, organic matter content and sludge concentration. Let’s take a look at the water quality monitoring issues in the sewage treatment process together!
The content of organic matter can be obtained by monitoring the detection of COD and BOD, and photometric methods can be used for detection. Its water treatment process monitoring items such as dissolved oxygen, COD, and BOD! Both dissolved oxygen and sludge concentration are measured by online analyzers. Therefore, for the control of water treatment processes, monitoring sewage discharge is very important! Online detection of dissolved oxygen control can achieve the biological treatment state and reduce the energy consumption of the operation of sewage treatment plants.
In addition, in the phosphorus removal and degassing process, the online monitoring of phosphate and ammonia concentrations is also very important for optimizing the water treatment process, saving energy, and ensuring the effluent quality meets the discharge standards.
During the acid-base treatment process, pH value is an indispensable monitoring parameter. Aerobic, anaerobic and anoxic treatments can only be carried out within a certain pH value range and also require pH value detection.
During the oxygenation disinfection stage, it is necessary to measure the residual chlorine content in the water and control the amount of chlorine added.
