生物反应器填埋场系统有机物降解动力学模型

Biodegradation kinetic models of organic compound in bioreactor landfill system

为了研究生物反应器填埋场系统对生活垃圾的处理效果,在对系统的运行特性进行研究基础上,以COD表示有机物质量浓度的变化,建立了生物反应器填埋场系统有机物降解动力学模型.研究表明,系统对COD有较好的处理效果,至试验的145 d时,系统的COD已降至100 mg/L以下,不需要处理即可直接排放;模型的模拟值与系统的实测值基本一致,可以预测生物反应器填埋场系统的出水水质.

With parameter COD, the biodegradation kinetic models of organic compound in bioreactor landfill system were established. The results showed that COD was blow 100 mg/L when 145 d passed and the leachate could be discharged directly without treatment. The stimulated value of models and the measured value of the system were in agreement with each other, so the quality of leachate of the system could be predicted.
