Description
Technical Field
The utility model relates to the field of wastewater treatment, in particular to a wastewater treatment device based on a magnetic loading activated sludge process.
Background
The traditional activated sludge process is one of the most commonly used methods in wastewater biological treatment processes. When the conditions such as the ratio of dissolved oxygen and carbon, nitrogen and phosphorus elements of the organic matter permit, the higher the sludge concentration is, the higher the organic matter removing ability is. However, the sludge concentration of the conventional activated sludge process can be maintained at most only about 3g/L for two reasons:
1) Too high sludge concentration, too many suspended matters carried by produced water, difficult sedimentation and separation, high turbidity of produced water, and adverse subsequent advanced treatment.
2) The higher the sludge concentration, the faster the sludge loss in case of difficult control of produced water turbidity, thus limiting further increase of the sludge concentration.
These factors limit the engineering applications of the activated sludge process at higher concentrations of wastewater organisms, requiring plant scaling or combination with other processes to achieve the desired treatment results, which can greatly increase investment and operating costs.
Therefore, there is a need for a wastewater treatment apparatus that increases the concentration of activated sludge while ensuring stable operation of the system.
