摘　　要：试验研究了水温、曝气强度和气水比等因素对 YDT生物接触氧化池挂膜的影响。结果表明 :生物接触氧化池挂膜受水温影响很大 ,水温越高 ,挂膜时间就越短 ,水温低于 15℃自然挂膜难以成功。在挂膜期间 ,采用较小的曝气强度和气水比可缩短生物膜的成熟时间。对判断生物膜是否成熟的指示性参数——氨氮去除率和 CODMn去除率进行了比较 。The effects of water temperature,areation strength and air/water ratio on biofilm culturing of YDT biological contact oxidation pond(BOCP)have been investigated.The results show that biofilm culturing of BCOP is affected greatly by water temperature;the higher the water temperature,the shorter the biofilm maturiation time;natural biofeilm culturing is difficult to succeed below 15℃ of water temperature.During the biofilm culturing,less biofilm maturation time will be needed if smaller aeration strength and air/water ratio are used.The comparision of indicators for biofilm maturation such as ammonia nitrogen removal ratio and COD Mn removal ratio shows ammonia nitrogen removal ratio is more suitable for BCCP.as an indicator.
