摘要
高寒地区污水水温偏低,严重影响生化处理系统中微生物的生长繁殖和代谢活性,导致处理效率低下,出水水质难以达标排放.近年来,利用高效微生物菌剂强化污染物的去除已成为高寒地区水污染控制领域的研究热点.本文总结了温度对污水生化处理系统的影响,分析了高效微生物菌剂的强化机理与优势,探讨了微生物菌剂在低温污水处理领域的应用现状,评价了实际处理效果和应用前景.因微生物菌剂强化技术具有处理效率高、投资和运行成本低、抗冲击负荷能力强等优势,为高寒地区污水生物处理提供了新思路.
Abstract
The low water temperature of sewage in alpine areas seriously affects the growth,reproduction and metabolic activity of microorganisms in the biochemical treatment system,resulting in low treatment efficiency and difficult discharge of effluent water quality.In re-cent years,the use of high-efficiency microbial agents to enhance the removal of pollutants has become a research hotspot in the field of water pollution control in alpine regions.In this paper,the influence of temperature on the wastewater biochemical system is summarized,the strengthening mechanism and advantages of high-efficiency microbial agents are analyzed,the application status of microbial agents in the field of low-temperature sewage treatment is discussed,and the actual treatment effect and application prospects are evaluated.Due to the advantages of high treatment efficiency,low investment and operating costs,and strong anti-shock load capacity,the microbial agents enhancement technology has improved a new idea for the biological treatment of sewage in alpine areas.
