摘要:
利用活性污泥2D模型(ASM2D)构建厌氧-缺氧-好氧(AAO)多模式工艺的模型,通过灵敏度分析,对模型的动力学参数进行校正.通过改变工艺运行模式,排泥量、内回流比和外回流比,优化多模式AAO工艺.结果表明:该污水处理厂的最优工艺运行模式为改良式AAO模式;当控制排泥量为2 000 m3·d-1时,内回流比为100%,外回流比为50%,出水CODCr、氨氮和总氮质量浓度等指标均可达到GB 18918-2002《城镇污水处理厂污染物排放标准》一级B标准;经过模拟和比较,曝气能耗比原来节省28.7%,内回流能耗相比原来节省37.3%.
Abstract:
Activated sludge model No 2D(ASM2D)has been used to establish the model of multi-mode anaerobic-anoxic-oxic(AAO)process. The kinetic parameters of the model were calibrated through the sensitivity analysis, and the sludge discharge capacity, the interior return ratio and external reflux ratio were adjusted in order to optimize the operation of multi-AAO process. The results showed that the optimal process operation of sewage treatment plant was the Modified AAO mode. If the capacity of sludge discharge was controlled to 2 000 m3·d-1, the interior return ratio could be 100%, the external reflux ratio 50%, and the concentrations of the effluent ρ(CODcr), ρ(NH3-N)and ρ(TN)all below the threshold values set out by the Chinese legislation of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants: GB 18918-2002 Class 1B. Meanwhile, after simulations and comparisons, the aeration energy consumption decreased by 28.7%, and the consumption of the internal reflux energy dropped by 37.3% compared to those of the past.
