Resumen de: CN122166932A

The invention relates to the technical field of resources and environments, in particular to a method for treating high-ammonia-nitrogen wastewater through a phycomycete mixed system and application. By regulating nutrition and operation parameters, a functional community with microalgae as a dominant and bacteria and cyanobacteria as a cooperative unit is constructed and maintained, and the relative abundance of the microalgae, the bacteria and the cyanobacteria is in a preset optimization interval. Microalgae such as nostoc and chlorella are mutualistic, bacteria such as flavobacterium and the microalgae are in an antagonistic relationship, and a positive and negative feedback mechanism maintains community balance and system robustness. The three functions complement each other, microalgae dominates CD-ROM nitrogen and phosphorus removal, cyanobacteria provide nitrogen fixation and stable support, functional bacteria participate in organic matter degradation and nitrogen circulation, and synergistic metabolism is realized through material exchange. Microbial ecology analysis proves that a stable community structure and an internal interaction mechanism are the core of efficiently and stably reducing ammonia nitrogen. The technology is accurate in regulation and control, stable in operation, environment-friendly and economical, and can be widely applied to treatment of various ammonia nitrogen polluted water bodies.
