稳定塘污泥降解的静态模拟研究

通过人工控制下的实验室内静态模拟,研究了稳定塘污泥降解过程中的pH值变化趋势?有机物浓度?淤积时间?温度对污泥降解速率的影响以及污泥降解的数学模型?结果表明:污泥降解过程的pH值先降低?后回升,继而趋于稳定;有机物浓度对污泥降解速率无影响,污泥降解速率与降解时间的关系为r∝t-α;温度对降解速率常数的影响符合Arhenius指数关系式;实验室内的污泥降解符合零级反应规律? 

Static Simulation Research on Sludge Degradation Law in Stabilization Pond

Through static simulation in laboratory under artificial control, sludge degradation model and its effects caused by pH value trend, organism concentration, deposition time and temperature were studied. The resultsshow that pH value decreases at first, then increases and gradually stabilizes;organism concentration has little effect on sludge degradation; the relation between the rate of sludge degradation and its time is r∝t -α ; the effect of temperature on the rate constant of sludge degradation coincides with the Arrhenius exponential expression; the sludge degradation law in laboratory coincides with zero order reaction law.
