活性污泥工艺模拟系统软件在氧化沟中的应用

The application of the activated-sludge-process-stimulated system software on the oxidation ditch

采用基于IAWPRC活性污泥法模型开发的活性污泥工艺模拟系统软件,对氧化沟的运行结果进行了模拟.结果表明,实际运行的水力停留时间满足去除COD和氨氮的需要,模拟出水与实际氧化沟相应的出水值相一致,该软件具有稳定性好,收敛速度快的特点.

The activated-sludge-process-stimulated system software on the basic of IAWPRC activated sludge model was used to stimulate the oxidation ditch operation. The results showed that hidrodynamic retention time (HRT) in the actual operation satisfied the demand of the COD and ammonia-nitrogen removal; and the stimulated outflow values were consistent with the values of the actual oxidation ditch. The software has the characters of good stabilization and fast convergence speed.
