최근 폐광 주변지역에서 발생되는 광해문제가 심각한 환경문제로 대두되고 있는 실정에 있으며, 이러한 광해문제중에서 폐광 주변에 산재되어 있는 폐석들에서 유출되는 침출수들은 높은 산성도를 가짐과 아울러 유해한 각종 중금속을 함유하고 있어 이 침출수 처리에 대한 대책이 더욱 절실하게 요구되고 있는 것이다.In recent years, the mining problem occurring in the area around abandoned mines has emerged as a serious environmental problem. Among these mine problems, the leachate flowing out of the waste rocks scattered around the mine has high acidity and contains harmful heavy metals. Therefore, measures against this leachate treatment are urgently required.

또한, 상기한 침출수는 외부의 공기와 반응하면서 발생되는 침전물에 의하여 원활하게 배수되지 못하여 그 피해 범위도 확산되며, 또한 이러한 침출수문제는 장기간 지속적으로 일어날 뿐만 아니라 수질 오염과 토양 오염과 그리고 생태계에 직접적인 영향을 미치고 있는 것이다.In addition, the leachate is not drained smoothly by the sediment generated by reacting with the outside air, and the damage range is also spread, and the leachate problem is not only occurred continuously for a long time, but also directly related to water pollution, soil pollution, and ecosystem. It is affecting.

그러나 종래에는 폐석으로부터 발생되는 침출수가 그대로 외부로 배출하게 되어 있으므로 침출수에 포함된 중금속과 높은 산성도 및 낮은 용존산소로 인하여 환경을 극심하게 오염시키게 되며, 또한 상기한 침출수가 산소등과 반응하여 각종 산화물을 형성하면서 침전되어 침출수가 흐르는 통로를 막게되어 침출수가 원활하게 배수되지 못하는 문제점이 있었다.However, conventionally, the leachate generated from the waste-rock is discharged to the outside as it is, so that the heavy metal and high acidity and low dissolved oxygen contained in the leachate severely pollute the environment, and the leachate reacts with oxygen and various oxides. Sedimentation was formed while blocking the passage of the leachate flow, there was a problem that the leachate can not be smoothly drained.

따라서 본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 폐석으로부터 발생되는 침출수에 포함된 중금속을 제거함과 아울러 높은 산성도를 중화하고, 침출수가 흐르는 통로의 막힘을 방지할 수 있도록 하여 환경 오염을 방지함과 아울러 침출수가 원활하게 외부로 배수될 수 있도록 한 폐광산 침출수의 중금속 제거 및 중화장치를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to remove heavy metals contained in the leachate generated from the waste-rock and to neutralize high acidity, and to prevent the passage of the leachate flow path It is to provide a heavy metal removal and neutralization device of the waste mine leachate to prevent environmental pollution and to allow the leachate to drain to the outside smoothly.
