采用浸渍-焙烧法制备不同组分比例的Mn-Ce-Ox/γ-Al2O3双活性组分负载型催化剂,与臭氧联用降解模拟苯胺废水。催化臭氧氧化苯胺实验得出,浸渍液锰铈物质的量比为3:1、浸渍液Mn(NO3)2浓度为1.0 mol/L时,催化剂对苯胺模拟废水的降解效果最佳。用该催化剂催化臭氧氧化佛山市某纺织厂的实际废水,反应30 min后,苯胺质量浓度均在0.03 mg/L以下,达到国家行业废水排放标准。

通过梯度驯化,从土壤中分离筛选出能以毛用活性红PW-6g为唯一碳源的4株菌株,对其进行偶氮还原酶、苯胺双加氧酶、苯甲酸-1,2-双加氧酶、邻苯二酚-1,2-双加氧酶、邻苯二酚-2,3-双加氧酶活性测定,确定综合酶活性较好的菌株,鉴定其为Bacillus subtilis spp.菌株。对该菌株的脱色反应条件进行研究,结果表明,当PW-6g初始质量浓度为600 mg/L时,在pH为7.5、温度为35℃、接种量为4%、盐质量浓度小于40 g/L的条件下,Mabhk-3脱色48 h对PW ...
