Experimental Study on the Treatment of Black and Odorous Water Bodies by Micro Nano Aeration Combined with Microbial Growth Promoters
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 ℃.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.
