[0002] The laboratory wastewater circulation treatment device is a device specially used to treat laboratory wastewater. It aims to achieve the recycling of wastewater, reduce environmental pollution and save water resources.

[0003] Existing laboratory wastewater circulation treatment devices usually adopt a combination of physical, chemical and biological treatment methods; first, solid particles and suspended matter in the wastewater are removed by physical filtration; then, heavy metal ions, organic matter and other harmful substances in the wastewater are removed by chemical methods; finally, the organic matter in the wastewater is further degraded by biological treatment to meet the standards for recycling. However, laboratory wastewater is generally generated in various experimental processes, and the generated laboratory wastewater cannot be directly poured into the sink for discharge. Instead, the laboratory wastewater needs to be tested for acidity and alkali and differentiated, and the differentiated wastewater is uniformly collected and treated for centralized circulation treatment.
