A new phenol-degrading bacterium with high biodegradation activity and high tolerance of phenol, strain B3, was isolated from the coking wastewater of Coking Plant of Shougang in Beijing. The physic-biochemical characteristics as well as 16SrDNA gene sequence analysis were applied to classify the bacteria and its characteristics of degrading phenol. The results showed that the strain B3 was identified...
The research studied enhanced treatment of sewage from discharging points of rivers by biofilm process dosing with enzyme and the effect of phenol on removal rates of the main pollution indexes, and investigated promotion effect of enzyme (including the laboratory developed compounded enzyme and the foreign composite enzyme) on treatment of sewage by biofilm process. The research results indicated...
A strain of bacterium, Rhodopseudomonas palustris PSB-1D, which could degrade o-chlorophenol (2-CP), was isolated and screened from shallow sediment in downstream side of the sewage outfall of an insecticide factory. The strain PSB-1D could not utilize 2-CP as the sole carbon source and energy resource. However, it could degrade 2-CP in the presence of co metabolism substrates. Seven kinds of additional...
Phenol is a highly toxic and carcinogenic compound and its biological treatment has been broadly agreed that it is economical, practical and it leads to a complete removal of phenol (degraded to inorganic, CO2 H2O etc.). The effect of acclimated activated sludge in the phenol biodegradation has been studied. First, the batch acclimated period have been performed gradually by elevated the activated...
