摘要

我们正在开发一种水处理系统，用于从地热水中去除砷。采用氢氧化铁(III)共沉淀法，将As吸附到氢氧化铁(III)团中，采用超导磁体高强度高梯度磁选(HIHGMS)提取团。我们证明，该方法将砷从3.4mg/L降至接近日本环境标准的0.015mg/L，并且我们高速净化了大量的水。我们还描述了一种可行的工厂的估计，用于去除地热水中的砷供公众使用。

Decontamination of Geothermal Water

We are developing a water processing system for the removal of arsenic from geothermal water. We adopt the coprecipitation method of Fe (III) hydroxide, in which As is adsorpted to the flocks of Fe (III) hydroxide, and the High Intensity and High Gradient Magnetic Separation (HIHGMS) by superconducting magnets to extract the flocks. We demonstrated that the method reduce arsenic to 0.015mg/L that closed to the environmental standard in Japan, from 3.4mg/L and we purified a large amount of water at high speed. We also describe an estimate of a feasible plant for removal of arsenic in the geothermal water for public use.
