摘要：
A biological purifier of the present invention includes chaff retaining sulfate-reducing bacteria. A biological purification system of the present invention includes a treatment container in which anaerobic conditions are maintained, and the above biological purifier is stored; a supply system for supplying the untreated waste water into the treatment container; and an discharge system for discharging treated water from which the heavy metal ions have been removed in the treatment container by the purifier, from the treatment container. In a biological purification method of the present invention, the biological purifier and the untreated waste water are brought into contact with each other under anaerobic conditions, thereby precipitating and removing the heavy metal ions as sulfide from the untreated waste water.
