摘要:
基于活性污泥数学模型ASM2D,参照实测出水水质对所建模型进行校准与验证,优化常州市戚墅堰污水厂微孔曝气氧化沟工艺。探究微孔曝气氧化沟处理低碳源城市污水的效能。针对进水分配比、污泥回流比、SRT及曝气区容积4个方面,进行模拟分析及优化调节。结果表明:缺氧段与厌氧段进水分配比为4:6时,系统可最大程度利用原水碳源; SRT控制为24.2 d、污泥回流比控制在60%～67%时,可达到较好的脱氮除磷效果; 将好氧区的前1/3停止曝气,对TN和TP的去除都有贡献。该优化方案的实施能在一定程度上提高污水处理厂运行效率,并节能降耗。
Abstract:
The microporous aeration oxidation ditch process of Changzhou Qishuyan Sewage Plant was optimized based on the activated sludge model ASM2D. The process model was structured and adjusted referring to the practical processes, the effluent water quality components and the parameters of the model.The efficiency of microporous aeration oxidation ditch was explored in the treatment of low carbon source municipal sewage. The simulation and optimization were carried out in four aspects: water inlet distribution ratio, return sludge ratio, SRT and aeration volume. The results show that the system can make full use of the raw water carbon source when the water inlet ratio was 4:6 in anoxic zone and anaerobic zone. When the SRT was 24.2 d and the return sludge ratio was controlled at 60%～67%, a good nitrogen and phosphorus removal effect can be achieved. The aeration of the first 1/3 of the aerobic zone was stopped, which contributed to the removal of TN and TP. The optimization scheme can improve the operation efficiency of sewage treatment plant, save energy and reduce consumption.
