摘　　要：利用平板分离方法,从废纸造纸封闭循环废水处理的生物接触氧化池中筛选出优势的高效菌株,采用形态学观察和生理生化试验发现主要由动胶菌属(Zoogloea sp.)和假单胞菌属(Pseudomona sp.)组成。用吸光光度法,确定其最佳生长时间。通过平行对比实验,在不同时间取样测定COD值,比较得出高效菌对废纸造纸循环废水的处理能力远高于普通菌。Two preferential strains mainly consist of Zoogloea sp. and Pseudomonas sp. respectively were screened for wastewater treatment in recycled paper mills, and the composite strain with a ratio of 1∶1 was used in a bio-contact oxidation basin. The 10 day bio-film colonization with the strain resulted in a stable COD removal of 93%, satisfying the quality requirement for recirculation of treated wastewater.
