摘　　要：试验以梅州市典型黑臭水体采集的水样为处理对象,研究微纳米曝气联合微生物促生剂处理黑臭水体的效果。试验设置3种处理方案,持续27d。A组无曝气,仅投加微生物促生剂;B组采用普通曝气,联合投加微生物促生剂;C组采用微纳米曝气,联合投加微生物促生剂。试验期间,C组溶解氧(Dissolved Oxygen,DO)浓度提升至6.2mg/L,化学需氧量(Chemical Oxygen Demand,CODcr)去除率为73.22%,总氮(Total Nitrogen,TN)去除率为93.44%,氨氮(NH3-N)去除率为96.11%,总磷(Total Phosphorus,TP)去除率为85.35%;C组最佳进气量为0.5L/min,最佳处理温度为25℃。结果表明,微纳米曝气联合微生物促生剂的方案在提升水体复氧能力和污染物去除效果方面具有显著优势。The experiment takes water samples collected from typical black and odorous water bodies in Meizhou city as the treatment object,and studies the effect of micro nano aeration combined with microbial growth promoters on the treatment of black and odorous water bodies.Three treatment plans are set up for the experiment,lasting for 27 d.Group A has no aeration and only microbial growth promoters are added;group B uses ordinary aeration combined with the addition of microbial growth promoters;group C adopts micro nano aeration combined with the addition of microbial growth promoters.During the experiment,the Dissolved Oxygen(DO)concentration in group C increases to 6.2 mg/L,the Chemical Oxygen Demand(CODcr)removal rate is 73.22%,the Total Nitrogen(TN)removal rate is 93.44%,the ammonia nitrogen(NH3-N)removal rate is 96.11%,and the Total Phosphorus(TP)removal rate is 85.35%;the optimal intake volume for group C is 0.5 L/min,and the optimal treatment temperature is 25°C.The results indicate that the combination of micro nano aeration and microbial growth promoters has significant advantages in enhancing water reoxygenation capacity and pollutant removal efficiency.
