Abstract：Vibrio Fischeri as spawn, a comprehensive test of the waste water discharged by medical institutions was carried out, combine with the determination of fecal coliform. Monitoring results of fecal flora of waste water conformed to the requirements of the corresponding standard limit, but medical waste water with biological toxicity generated certain biological inhibition rate to photogenic bacterium. The waste water of infectious diseases and tuberculosis medical institutions possessed biological inhibition rates as high as 44.7%and 49.8%. The inhibition rate of waste water from traditional Chinese medicine medical institutions caused a minmum inhibition rate of 8.1%. The experimental results showed that the luminescent bacteria method could be applied to the determination of waste water of medical institutions.
