Progress in the application of microbial agents in low temperature wastewater treatment
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.
