The laboratory wastewater treatment penalty is based on the principles of classification networks, on-site treatment, real-time on-site treatment penalties, simple operation, waste disposal, and cost reduction. For laboratory wastewater with high organic concentrations, strong toxicity, and unstable water quality, biological treatment methods are not ideal, and physical-chemical methods show a clear advantage in treating such wastewater. Different types of wastewater and compositions of pollutants require different treatment methods and levels. Organic wastewater has greater limitations and risks compared to inorganic wastewater.
