【摘要】 城市污水冷热源开发利用具有重要的节能与环保意义,但在寒区是否会对污水生化处理产生严重的影响是关键性问题.基于实际运行的两个典型项目,测试污水排放温度分布,研究城市污水干渠周边土壤对水温的调节特性,在此基础上进一步分析污水处理流程的温度分布情况,并从生化角度分析污水冷热源对污水生化处理的影响.研究表明:土壤对污水水温具有调节作用,被利用污水水温不低于8℃时,污水冷热源不影响污水处理厂进水水温,污水处理曝气池水温在5~7℃内,水处理能力由耐冷菌承担,再提取2~3℃污水热能对水处理无明显影响,水温均在耐冷菌活性范围内.
【英文摘要】 It's important to exploit and utilize the sewage as cool and heat source for energy saving and environmental protection,but we need to think of how great the effect on wastewater biological treatment is in cold area.Based on two typical engineerings which were operating in practice,the article analysed the temperature distribution of sewage system and demonstrated the adjustable characteristic of the ground in nearby sewage trench to water temperature.Furthermore,the study discussed the effect of the sewage...
