中文摘要：
以微生物增殖动力学的基本方程-莫诺方程为出发点,通过氮同位素分析比较了具有同源性微生物的生物陶粒滤床和生物活性炭床的有机物生物降解规律,建立了生物活性炭床的有机物生物降解动力学方程,提出在污水再生利用过程中生物活性炭床符合高基质有机物降解动力学模型,即有机物降解呈一级反应动力学方程。以此方程为基础,分析计算了生物活性炭床沿炭床深度的吸附性能,结果表明,在生物活性炭床中,随生物功能的减弱,生物活性炭床对有机物的吸附能力逐渐加强。
英文摘要：
We established the biodegradation dynamic equation of organic matters in the bio-activated car- bon bed, which based on the fundamental equation of microorganism proliferation kinetic-Monod equation. Com- paring the biodegradation rule of organic matters in bio-activated carbon bed and bio-ceramic filter bed with ho- mologous microbial by nitrogen isotopes analysis, it was showed that the rule of the organic matter degeneration in bio-activated carbon bed conformed with the degeneration dynamics model of high matrix organic matters during the wastewater reclamation process, namely the first order reaction kinetic equation. Then the adsorption per- formance along the biological activated carbon bed depth was calculated by the equation. The results showed that the adsorption capacity of biological activated carbon for organic matters was gradually enhanced as the weakening of biological function.
