Abstract:
The substrate biodegradation kinetics of domestic seawater was studied by using the completely-mixing activated sludge system.The degradation rate constant of the substrate and kinetics models have been discovered when the wastewater contains 12 %, 24%and 36%seawater, respectively.With the seawater salinity increasing,the degradation rate constant of substrate drops.

摘要：
作者采用完全混合活性污泥法研究了大生活用海水进入城市污水系统后,不同海水盐度下污水的基质降解动力学。得出了污水中分别含 12 %、24 %和 36%海水时的基质降解速率常数和基质降解动力学模型。随着污水中海水比例的增大,基质降解速率常数逐渐变小。
