Kinetic study on the biodegradation of organic pollutants in coastal seawater of Dalian

, : Kinetic study on the biodegradation of organic pollutants in coastal seawater of Dalian. Huanjing Kexue 18(4): 41-44, 93

In this paper, studies were carried out to determine the biological degradation kinetic characteristics of four kinds of organic pollutants in coastal seawater of Dalian. By adding benzene, nitro-benzene, phenol and aniline to natural sea water, respectively, the biochemical oxygen demand (BOD) of the organic compound was tested under different concentration groups of 0.1 mg/L, 0. 3 mg/L, 0.5 mg/L, 1 mg/L etc. Through data analysis, the kinetic parameters K and L-0 of the compound were obtained (K represents first-order biodegradation rate constant, L-0 represents ultimate BOD). The mathematic model y = L-0 (1-10-Ki) of the BOD, which was expressed by the variation of BOD with time. The results calculated according to the model were similar to the experiment values. Some influence factors on the biodegradation rate of the compound were also analyzed and discussed in this paper. The conclusion was that biodegradation was mainly affected by molecular structure.
