Abstract
본 발명은 폐수중에 고농도로 함유된 시안화합물을 제거하는 방법에 관한 것으로, 폐수의 pH를 조절하고 아황산가스와 산기장치에 의해 주입되는 공기를 이용하여 폐수중의 시안화합물과 반응시켜 고농도의 시안화합물을 산화시켜 제거함으로서, 처리설비 용량이 적고 운전조작이 간편하며, 슬럿지 발생량이 매우 작을 뿐 아니라 폐수중의 시안화합물을 99% 이상으로 제거가 가능한 효과적이고 안정적으로 고농도 시안함유 폐수를 처리할 수 있는 방법을 제공하고자 하는데, 그 목적이 있다. 상기한 목적을 달성하기 위한 본 발명은 페수중에 함유된 시안화합물을 제거하는 방법에 있어서, 상기 폐수의 유량 및 농도가 일정하게 공급되도록 조정하여 폐수를 균등화시킨 후, 균등화된 폐수를 황산 또는 소설회를 이용하여 pH를 6-9로 조절하는 단계; 및 pH가 6-9로 조절된 폐수에 산화촉매로서 구리이온을 40-80mg/L로 투입하고, 폐수중의 시안화합물 농도 대비 아황산가스를 5-7배 주입함과 동시에 아황산가스 유입유량 대비 공기를 15-20배 폭기함으로서 폐수중의 시안화합물을 산화분해시켜 제거하는 단계를 포함하여 이루어지는 폐수증의 시안화합물 제거방법에 관한 것을 그 요지로 한다.The present invention relates to a method for removing cyanide compounds contained in high concentrations in wastewater, and to control the pH of the wastewater and reacting with cyanide compounds in the wastewater using air injected by sulfurous acid gas and an acid generator to obtain a high concentration of cyanide compounds. By oxidizing and removing chlorine, the capacity of treatment facility is small, the operation is easy, and the sludge generation amount is very small. The purpose is to provide a method. The present invention for achieving the above object in the method for removing the cyan compound contained in the waste water, after adjusting the flow rate and concentration of the waste water is uniformly supplied, the equalized waste water is sulfuric acid or novel ash Adjusting the pH to 6-9 using; And 40-80mg / L of copper ions as an oxidation catalyst in the wastewater adjusted to pH 6-9, injecting sulfuric acid gas 5-7 times to the concentration of cyanide in the wastewater, The present invention relates to a method for removing cyanide compounds in wastewater, which comprises oxidatively decomposing and removing cyanide compounds in wastewater by aeration of 15-20 times.
