Brewery wastewater from Baijiu production is characterized by high organic concentration, high energy consumption for treatment and low resource recovery rate, which seriously restricts the green transformation of the Baijiu industry and the achievement of the “dual carbon” goals. In this study, a coupled process of anaerobic hydrogen production and microalgal carbon sequestration was proposed, and a trinity low-carbon resource utilization technical system integrating wastewater treatment, energy recovery and carbon emission reduction was constructed. Through optimizing pretreatment processes, screening hydrogen-producing microbial communities, regulating microalgal carbon sequestration conditions and analyzing the algae-bacteria synergetic mechanism, the efficient conversion of organic matter in wastewater into hydrogen and microalgal biomass was realized. The experimental results showed that under the optimal parameters (anaerobic fermentation temperature of 35˚C~40˚C, hydraulic retention time (HRT) of 38 h and C/N ratio of 20~30; microalgal culture with light intensity of 6000 Lux and CO₂ aeration rate of 7% v/v), the hydrogen production rate was no less than 1.5 L H₂/(L∙d), the COD removal rate exceeded 85%, the microalgal carbon sequestration efficiency was not less than 0.8 g CO₂/g microalgal biomass, the carbon emission reduction per cubic meter of wastewater reached no less than 15 kg CO₂, and the treatment cost was no more than 15 CNY/m3. This process breaks through the high energy consumption bottleneck of traditional technologies, provides a novel technical approach for the low-carbon resource utilization of wastewater in the Baijiu industry, and has both theoretical value and engineering application prospects. %K 白酒酿造废水， %K 厌氧产氢， %K 微藻固碳， %K 低碳， %K 资源化利用
