Respirometric methods for rapid toxicity/inhibition assessment of industrial wastewater

摘要

The failure of biological treatment processes in industrial and municipal wastewater treatment plants is one of the major causes of toxic throughput and noncompliance with discharge permit limits. Both operators and regulatory agencies are placing increased emphasis of controlling toxic or inhibitory discharges. Monitoring the oxygen uptke rate (OUR) of industrial wastes or mixed influent and prompt determination of their treatment inhibition potential (TIP) to the plant's biomass (RAS) can prevent costly upsets. Rapid monitoring techniques using respirometry are valuable for both industries and municipalities becase they make data availale in a preventive, rather than historical, time frame.
