摘要
山东某大型水质净化厂迁建项目设计规模25×10^(4) m^(3)/d,根据原水水质特点和出水水质要求,针对性地采用“预处理+初沉池+多点进水多级AO生物反应池+高效沉淀池+V型滤池+臭氧催化氧化池+接触消毒池”主处理工艺路线,并运用厂内光伏和多级AO工艺耦合精确控制系统等节能降耗工程实践来降低运行成本。实际运行效果表明,出水水质可稳定达标,节能降耗工程成效显著,2023年光伏绿色发电量约占总用电量的15%,精确曝气系统降低平均吨水电耗约12%,精确碳源投加系统降低平均吨水碳源药耗约10%。
The design capacity of the relocation project for a large‑scale wastewater treatment plant in Shandong Province is 25×10^(4) m^(3)/d.Based on the characteristics of the raw wastewater quality and the effluent quality requirements,the main treatment process route is specifically selected as follows:pretreatment,primary sedimentation tank,multi‑point feeding multi‑stage AO biological reaction tank,high‑efficiency sedimentation tank,V‑shaped filter,ozone catalytic oxidation tank and contact disinfection tank.Additionally,energy‑conservation and consumption‑reduction measures,such as on‑site photovoltaic power generation and multi‑stage AO process integration with precise control systems,are implemented to reduce operational costs.The actual operational results demonstrated that the effluent quality consistently met the requirement specified in the discharge standard,and the energy‑conservation and consumption‑reduction initiatives yielded significant outcomes.In 2023,the share of green photovoltaic power generation accounted for approximately 15%of total electricity consumption.The implementation of the precise aeration system reduced the average energy consumption per ton of treated wastewater by approximately 12%,while the precise carbon source dosing system decreased the average consumption of carbon source per ton of wastewater by around 10%.
