본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (2)

복합 중금속 성분 함유 폐수를 처리함에 있어서, 혼합폐수에 차아염소산나트륨을 가하고, 폭기시키면서 소석회 또는 가성소다 수용액으로 가하여 폐수액의 pH를 11∼12로 조정하고, 계속 폭기시키면서 황산철을 가하여 폐수액의 pH를 9∼8로 낮추고, 염화제1철 또는 염화제2철을 가해 pH를 4∼4.5로 조정한 후, 황화나트륨을 가해 pH를 6.5∼7로 맞춘 다음, 통상의 고분자 응집제를 가함을 특징으로 하는 중금속 함유 폐수의 처리방법.In treating wastewater containing complex heavy metal components, sodium hypochlorite is added to the mixed wastewater, and the pH of the wastewater solution is adjusted to 11-12 with aeration of limestone or caustic soda with aeration, and iron sulfate is added to the wastewater while continuing aeration. The pH is lowered to 9-8, ferric chloride or ferric chloride is added to adjust the pH to 4-4.5, and sodium sulfide is added to adjust the pH to 6.5-7, followed by the addition of a conventional polymer flocculant. A method for treating heavy metal-containing wastewater. 제1항에 있어서, 차아염소산을 폐수량에 대해 0.3∼0.6중량부 첨가함이 특징인 방법.The method according to claim 1, wherein hypochlorous acid is added in an amount of 0.3 to 0.6 parts by weight based on the amount of wastewater. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
