According to the survey, most laboratories discharge wastewater after simple treatment without any additional processing. It is known that the quality of laboratory wastewater is complex, with irregular discharge cycles and unsteady drainage. The pollutants in the wastewater are also complex, containing not only organic substances like detergents but also acids, bases, and toxic/hazardous materials. If such wastewater containing heavy metals and other complex substances is discharged without treatment, it could cause significant harm to human health and the surrounding environment.

If wastewaterPHThe facility can be omitted if the value fluctuation is minimal. Waste water treatmentpHThe neutralized wastewater is then 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 defoamer. 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 the microorganisms. This requires a heat exchanger to alter the temperature of the microorganism environment. Stabilize the temperature of the microorganism environment at40Approximately degrees Celsius. Wastewater is sent to a sedimentation tank for secondary treatment after biological aeration. After sedimentation, part of the sludge is recycled to the aeration tank 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 sustain the continuous growth of microorganisms, further biologically treat malodorous gases, and significantly reduce harmful substances. It can be directly discharged to meet standards.
