【摘要】 采用新型复合酶制剂(BZ剂)处理城市受污染景观水体。研究结果表明:该制剂的使用对COD、NH3-N、TP等有明显的净化效果。在本试验条件下,BZ剂投加量为0.4 mg/(L.d)时,CODCr、NH3-N、TP的最终去除效果最好,分别达到25.0%7、7.6%2、6.1%;相同投加量条件下,水质净化效果不曝气优于曝气状况。更多还原

【Abstract】 The treatment of polluted urban scenic waters was studied by use of the compound enzyme preparations（Bacto-zyme agent）.The result indicates that COD,NH₃-N and TP can be obviously degraded by the compound enzyme.Under the conditions when the BZ agent added was 0.4?mg/Ld in the experiment,the maximal removal rates of COD,NH₃-N and TP could reach 25.0%,77.6% and 26.1% respectively.With the same amount of BZ agent added in the water,the effect of water purification without aeration was better than that with aeration.更多还原
