This invention relates to the field of resource and environmental technology, specifically to a method and application of an algae-bacteria hybrid system for treating high ammonia nitrogen wastewater. By regulating nutrient and operational parameters, a functional community is constructed and maintained, dominated by microalgae and supplemented by bacteria and cyanobacteria, with their relative abundance within a preset optimized range. A clear interspecific interaction network forms within the system: microalgae such as *Nostoc* and *Chlorella* exhibit mutualistic symbiosis, while bacteria such as *Flavobacterium* show antagonistic relationships with these microalgae. Positive and negative feedback mechanisms maintain community balance and system robustness. The three components complement each other: microalgae primarily drive photocatalytic nitrogen and phosphorus removal, cyanobacteria provide nitrogen fixation and stability, and functional bacteria participate in organic matter degradation and nitrogen cycling, achieving synergistic metabolism through material exchange. Microbial ecological analysis confirms that a stable community structure and internal interaction mechanisms are the core of efficient and stable ammonia nitrogen reduction. This technology offers precise regulation, stable operation, and is environmentally friendly and economical, and can be widely applied to the treatment of various types of ammonia nitrogen-polluted water bodies.
