摘　　要：以安徽省某工业园区的低C/N比废水为研究对象,采用连续曝气、定期换水的方式对微生物进行培养驯化。结果表明,当COD∶N∶P为100∶5∶1,相当于COD、N、P浓度分别为600mg·mL-1、30mg·mL-1和6mg·mL-1时,COD的最高去除率为95.4%,出水COD为27.5mg·mL-1,出水氨氮稳定在5mg·mL-1;当COD∶N∶P调为100∶20∶1时,即COD、N、P浓度分别为600mg·mL-1、120mg·mL-1和6mg·mL-1时,出水COD的最低值为101.0mg.L-1,出水氨氮最低值为28.4mg·mL-1,低C/N比对微生物产生了抑制作用,经过20d的驯化基本达到排放标准。In order to enable the microorganisms to adapt low C/N for decreasing carbon source addition,the method of continuous aeration and refreshing the water periodically is adopted to acclimatize microbe.The wastewater is from one industrial park in Anhui province.The results show that when COD∶N∶P is 100∶5∶1,for which the concentration of COD,N,P is 600 mg·L-1,30 mg·L-1 and 6 mg·L-1 respectively,the highest removal rate of COD is 95.4%,the effluent concentration of COD is 27.5 mg·L-1,and the effluent concentration of NH3-N is stably at 5 mg·L-1.But when COD∶N∶P is 100∶20∶1,for which the concentration of COD,N,P is 600 mg·L-1,120 mg·L-1 and 6 mg·L-1 respectively,the minimum effluent concentration of COD and NH3-N is 101.0 mg·L-1 and 28.4 mg·L-1 respectively.Low C/N has inhibitory effect on microorganism.After twenty days＇acclimation,the effluent concentration of COD and NH3-N meet the discharge standard.
