摘要：
采用FeCl3-CaO混凝沉淀和Fenton氧化两步法处理高COD、含有机胂废水,结果表明,经该法处理后废水总砷质量浓度可降至0.5 mg/L以下,COD降至150 mg/L以下,达到国家二级排放标准要求,且产生的废渣和消耗的原料均大幅度下降,有较大的工业化推广价值。

Abstract:
The high COD and organoarsenic-bearing wastewater has been treated by means of the two-step process,coagulating sedimentation and Fenton oxidation.The results show that the total arsenic in the treated wastewater can be declined to below 0.5 mg/L and COD below 150 mg/L,and both of the waste residue produced and raw material consumed decline greatly.It has greater promotion value.
