水质 微型生物群落监测 PFU法
Application Summary AI generated
This standard specifies the PFU (Polyurethane Foam Unit) method for monitoring water quality by analyzing the microbial community structure that colonizes artificial substrates. It is applied in environmental monitoring and ecological assessment of freshwater bodies, such as rivers, lakes, and reservoirs, to evaluate the biological effects of pollution or water treatment processes. The method is used by environmental agencies and research institutions for long-term or rapid bioassessment of aquatic ecosystem health.
