摘要:

選用(yong)(yong)鐵碳(tan)微電解處(chu)理水(shui)(shui)(shui)源(yuan)中(zhong)的Cr(Ⅵ),研(yan)究其對Cr(Ⅵ)的去除效(xiao)(xiao)果和各(ge)種因素(su)的影響。結果表明,在不調pH的條件下(原水(shui)(shui)(shui)pH=5.8~6.4),反應時間為(wei)(wei)(wei)40min,六(liu)價鉻為(wei)(wei)(wei)1mg/L,Fe/C=7/3,總量為(wei)(wei)(wei)14g的鐵碳(tan),重復處(chu)理100mL的鉻液可(ke)以(yi)利(li)用(yong)(yong)6~8次,水(shui)(shui)(shui)樣經該條件處(chu)理后去除率達(da)95%以(yi)上,效(xiao)(xiao)果良好(hao)。在此基礎上進行(xing)動態連續實驗,流量為(wei)(wei)(wei)8mL/min,鉻液為(wei)(wei)(wei)1mg/L,不調節pH情況下,蒸餾水(shui)(shui)(shui)配鉻液的可(ke)以(yi)運(yun)行(xing)60d,出(chu)水(shui)(shui)(shui)濃度(du)為(wei)(wei)(wei)0.007~0.012mg/L,處(chu)理率都達(da)95%以(yi)上,出(chu)水(shui)(shui)(shui)達(da)到(dao)《生活飲用(yong)(yong)水(shui)(shui)(shui)衛生標準》(GB5749-2006)中(zhong)六(liu)價鉻的要(yao)求0.05mg/L,總鐵的要(yao)求0.3mg/L。該技術在實驗室實驗的基礎上,取得了較好(hao)的處(chu)理效(xiao)(xiao)果,對于研(yan)究水(shui)(shui)(shui)源(yuan)水(shui)(shui)(shui)處(chu)理新技術有參考價值。
