The survey shows that most research institutions simply treat and discharge their wastewater without any additional processing. It is known that laboratory wastewater is complex in quality, with irregular discharge cycles and drainage patterns. The pollutants in the wastewater are also diverse, containing not only organic substances like detergents but also acids, bases, and toxic/hazardous materials. If such complex wastewater containing heavy metals is discharged without treatment, it could pose significant harm to both human health and the surrounding environment.

If the wastewaterPHIf the value fluctuation is minimal, the facility can be omitted. Wastewater treatmentpHAfter neutralization, the wastewater is sent to the biological aeration pond for biological treatment. The nutrient tank provides essential nutrients to the microorganisms during the wastewater treatment process, helping them maintain a stable population and survive stably. Blower24Continuous aeration of the biological aeration pond in hours. The function of the defoaming tank is to effectively remove foam by adding a certain proportion of defoaming agent. While microorganisms are growing, they often release a large amount of heat due to metabolism. If the heat is not released in time, it will directly affect the reproduction of microorganisms. This requires a heat exchanger to alter the temperature of the microorganism environment. Stabilizing the temperature of the microorganism environment at40Approximately centigrade. After biological aeration treatment, the wastewater is sent to a sedimentation pond for secondary treatment. The sludge settled out is partially recycled to the aeration pond for treatment, while the remaining portion is dewatered and discharged externally. By adding a certain amount of acid or alkali and a certain amount of nutrient solution, the biological filter can maintain the continuous growth of microorganisms, further biologically treating the malodorous gases, which will greatly reduce the harmful substances. It can be directly discharged to meet standards.
