発明の名称 (英語) Biological purifier for water to be treated, biological purifying system, and method of biological purifying NEW
発明の概要(英語) A biological purifier using biomass sources which are unused is provided, which can sufficiently remove heavy metal ions from a water to be treated containing the heavy metal ions and sulfate ions over a long period of time, and can sufficiently suppress the organics pollution of the treated water.The purifier of the invention is characterized in containing a rice shell having sulfate reducing bacteria.In addition, a biological purifying system of the invention includes: a treatment container which contains the purifier and maintains anaerobic condition; a supplying system which supplies the water to be treated to the treatment container; and a discharging system which discharges the treated water, in which the heavy metal ions are removed in the treatment container by the purifier, from the treatment container.
