摘　　要：用铁屑-粉煤灰微电解和生化法组合工艺对矿区生产污水进行治理,研究了pH、反应温度、曝气量、驯化菌对其处理效果的影响。处理结果表明,微电解处理DDNP工业废水的最优反应条件是:m(Fe)/m(C)为10 g/5 g、反应温度为30℃、反应时间为24 h、曝气量30 L/h、生化处理pH值为4.5、温度为35℃。生化反应时间108 h,对废水COD的去除率可达90%以上,处理后废水的各项指标均达到国家规定的排放标准。The industrial wastewater in Xiejiaji coal mining area was treated by the integration processes of microelectrolysis of scrap iron with fly-ash and biochemical method. The factors that influence on treatment efficiency, such as pt-I value of wastewater, reaction temperature, air blast volume and domesticated bacteria were studied. The results of wastewater treatment shows, that the optimal reaction conditions in DDNP industrial wastewater treatment by microelectrolysis are m（Fe）/m（C）= 10 g/5 g, reaction temperature 30 ℃, reaction time 24 h, air blast volume 30 L/h, pH volume in biochemical process 4.5 and temperature 35 ℃. After 108 h biodegradation, removal rate of COD can be over 90% and all kinds of pollution indexes of the treated wastewater satisfy the national norms of China.
