Small pilot test of a resin wastewater biochemical treatment of the effluent Fenton reaction to determine the optimal control of the Fenton reaction conditions were as follows： n （H202） ： n （FeSO4） of 3：1, reaction time 120 min, the initial reaction pH 3, in these conditions, wastewater CODcr removal rate can reach 90 %. Wastewater treatment plant in accordance with the design of the optimal reaction conditions, after a week of continuous operation, CODc~ removal stabilized at around 90 %, better than the effluent water pollutant discharge limits （DB44/26-2001） level emission standard requirements.%通过对树脂废水一级生化处理出水Fenton反应的小试试验，确定出Fenton反应最佳控制条件为：n（Hz02）：n（FeS04）为3：1，反应时间120min，反应初始pH3左右，在此条件F，废水CODc，去除率可达到90％。按照该最佳反应条件设计的废水处理装置，经过一周的连续运行，CODc，去除率稳定在90％左右，处理后的出水优于《水污染物排放限值》（DB44／26—2001）一级排放标准要求。
