摘要
Provided is a biological purification agent capable of removing metal ions from water to be treated that contains metal ions and sulfate ions, the removal being achieved for extended periods of time even in low-temperature environments at water temperatures of 15°C or below. The present invention is a biological purification agent for precipitating sulfides of metal ions from water to be treated that contains the metal ions and sulfate ions, and removing the metal ions from the water to be treated, the biological purification agent being characterized in containing hulls of grain that harbor sulfate-reducing bacteria, and an organic substance-containing material that contains 5 mass% or more of crude protein.
