Study on pollutant removal performance with low DO and sludge micro-bulking
低溶解氧污泥微膨胀污染物去除性能的研究

In order to investigate the pollutant removal effect with low DO and sludge micro-bulking,the sequence batch reactor(SBR) operated in aeration/anoxic(O/A) process with mean DO value 0.5~0.9 mg/L has been studied.The results showed that the effluent water quality was good with low SS value,the SVI could be controlled at 200 mL/g,and the removal rates of COD,ammonia and phosphorus could reach 80%,90% and 90%,respectively.At the same time the aeration flow could be saved to 46.7%.It is concluded that the activ...
