摘要:本研究基于BSM2-G经典仿真模型,以造纸废水处理过程中的溶解氧浓度为控制变量,采用生命周期分析方法评估了6种不同控制方案下造纸废水处理过程的环境影响。结果表明,提高溶解氧设定值虽可改善出水水质,但由曝气电力消耗增加所导致的全球变暖潜值(1.86×![]() 104~2.07×![]() 104 kg CO2 eq)与人体毒性潜值(1.71×![]() 103~2.69×![]() 103 kg DCB eq)等增大,使环境影响总值呈先降低后升高的趋势,而通过调节溶解氧浓度和优化控制算法分别能够有效减少整体环境影响的15.2%和0.54%。 |
| Abstract:This study based on the BSM2-G simulation model, took the dissolved oxygen concentration in the papermaking wastewater treatment process as the control variable, and employed a life cycle assessment to evaluate the environmental impacts of six different control cases. The results showed that increasing the dissolved oxygen setpoint could improve effluent quality, but the resulting increased in aeration electricity consumption leaded to higher global warming potential (1.86×104~2.07×104 kg CO2eq) and human toxicity potential(1.71×103~2.69×103 kg DCB eq), causing the total environmental impact to initially decrease and then rise. However,by adjusting the dissolved oxygen concentration and optimizing control algorithms, the overall environmental impact could be effectively reduced by 15.2% and 0.54% respectively. |
