针对我国北方寒冷地区农村分散源养殖废水污染,以粒状活性炭为吸附剂,研究了低温（10℃）和常温（25℃）两种工况下静态吸附对养殖废水COD的去除效果和吸附特性。结果表明,低温下活性炭对废水COD的吸附饱和量为14.472mg/L,常温下饱和吸附量为7.564mg/L;二级吸附动力学方程可较好地描述该吸附过程;Langmuir等温吸附方程比Freundlich等温吸附方程能更好地拟合实验结果。本研究可为北方寒冷地区农村分散源养殖废水的处理提供数据参考和理论指导。

To resolve the aquaculture wastewater pollution in the cold regions of northern China countryside based on granular activated carbon as an adsorbent, this study researched the characteristics of adsorption aquaclture wastewater and remove COD efficiency under two situation of a low temperature （10 ℃） and room temperature （25 ℃） .The results showed that the low temperature activated carbon adsorption saturation on COD 14.472mg / L, room temperature, saturated adsorption capacity of 7.564mg / L; Both adsorption kinetic equation can well describe the adsorption process; The Langmuir isothermal adsorption equation more fit experimental results than the Freundlich isotherm equation. This study can provide data reference and theoretical guidance for the aquaculture wastewater treatment in the cold northern rural areas.
