摘　　要：采用催化铁内电解-沸石床-生物活性炭组合工艺进行了处理重度富营养化水的中试试验。通过对进水与出水浊度、TP、CODMn、UV254、总铁、NH3-N、和NO2-—N的监测,研究了本组合工艺对重度富营养化水体的处理性能。试验期间,水温约在10℃。初步结果表明,本组合工艺对浊度、TP、CODMn和UV254均有较好的去除作用,平均去除率达到50%以上,出水中铁含量均低于进水。由于水温过低,未观察到氨氮和亚硝酸盐氮的明显变化。Catalyzed iron internal electrolysis -zeolite bed -BAC was used to treat severely eutrophic water. The performmace about severely eutrophic water treatment of this combination process is examined through the analysis of influent and effluent of turbidity, total phosphorus, CODMn, UV254, total iron, ammonia nitrogen and nitrite nitrogen. During the pilot experiment, water temperature was about 10℃. The results indicated that the average removal efficiency of turbidity, total phosphorus, CODMn and UV254 reached more than 50% , and the concentration of total iron in effluent was less than that in influent. Due to low water temperature, there was no significant change in the concentration of ammonia nitrogen and nitrite nitrogen.
