Abstract

본 발명은 중금속을 함유하는 폐수로 부터 중금속을 제거하기 위한 중금속 처리제 조성물에관 한것으로서, 본 조성물은 디메틸티오카바민산나트륨, 황화나트륨 및 수산화칼슘과 물로 이루어지며, 이러한 구성의 본 조성물을 중금속 함유 폐수에 소량으로 투입하면 폐수중의 중금속 이온이 침전방해물질의 존재에도 불구하고 불용성염 상태로 침전하므로 보조제를 사용하지 않더라도 충분한중금속제거 효과를 달성할 수 있게 된다.The present invention relates to a heavy metal treatment composition for removing heavy metals from wastewater containing heavy metals, the composition consisting of sodium dimethylthiocarbamate, sodium sulfide, calcium hydroxide and water, In small amounts, heavy metal ions in the waste water precipitate in an insoluble salt state despite the presence of precipitation inhibitors, so that sufficient heavy metal removal effects can be achieved without using an auxiliary agent.
