摘要
采用进口高效微生物和普通微生物对校园生活污水进行处理,试验结果表明,高效微生物CODCr降解速率快,4 h时达到80.1%的CODCr最大去除率,能承受的最大进水负荷约为1.14 kg[CODCr]/(m3.d),而相同条件下普通微生物仅为69.2%,能承受的最大进水负荷约为0.76 kg[CODCr]/(m3.d)。根据两反应器稳态运行3个月的数据,前者对CODCr、LAS、NH3-N的去除率平均值为82%、75%、89%;而后者对CODCr、LAS、NH3-N的去除率平均值为72%、42%、78%。其它研究资料表明,高效微生物对高CODCr、NH3-N、挥发酚污水有很好的处理效果。高效微生物用于实际工程的实例也越来越多。
Domestic sewage from campus were treated by imported high-efficiency microorganism and general microorganism respectively, the results of the test showed that, the degradation rate of CODCr was faster by the highefficiency microorganism, the removal rate of CODCr reached the highest （80.1%） in 4 h, the maximum endurable influent loading was 1.14 kg[CODCr/（m^3·d）, while, under the same condition, the corresponding values were only 69.2% and 0.76 kg[CODCr/（m^3·d） respectively by general microorganism. According to the data got from the two reactors after 3 months of stable operation, the average removal rate of CODCr, LAS, NH3-N by the former one were 82%, 75%, 89% respectively, while, the corresponding values by the later one were 72%, 42%, 78% respectively. Some other research information showed that, highfficiency microorganism has a good effect on treatment of sewage with high concentration of CODCr, NH3-N, and volatile phenol, moreover, the examples of highefficiency microorganism used in practical projects also become more and more.
