GB/T 21796-2022
ActiveChemicals—Activated sludge respiration inhibition test
化学品 活性污泥呼吸抑制试验
Application Summary AI generated
This standard specifies a test method to determine the inhibitory effect of chemical substances on the respiration rate of activated sludge microorganisms. It is applied in environmental risk assessment and wastewater treatment contexts, particularly for evaluating the potential toxicity of industrial chemicals, pesticides, or pharmaceuticals to biological wastewater treatment systems. The test helps predict how a substance may disrupt microbial activity in activated sludge plants, guiding regulatory classification and safe discharge limits.
