前言为了合理地确定青岛市李村河污水处理厂的工艺流程和设计参数,中国市政工程华北设计院于1992.7.14—1992.9.10在青岛市进行了现场试验,分别采用AB工艺和A/O脱氮工艺进行了动态试验。由于李村河污水属于高浓度有机污水,其中TKN经常在80mg/L以上,有时高达100mg/L,在应用AB工艺进行试验的过程中,B段曝气池容易发生硝化反应,造成出水中NO_3-N含量很高,导致最终沉淀池经常大量浮泥,影响出水水质的稳定。针对上述问
Preface In order to reasonably determine the process and design parameters of Licunhe WWTP in Qingdao City, North China Design Institute of China Municipal Engineering undertook a field test in Qingdao City from July 14, 1992 to January 9, 1992, using AB technology and A / O Denitrification process was tested dynamically. Due to the high concentration of organic wastewater from Licun River, TKN is often above 80mg / L and sometimes up to 100mg / L. During the process of applying AB process, the B-section aeration tank is prone to nitrification, resulting in NO3 -N content is very high, resulting in a large amount of final sedimentation tank often floating mud, affecting the stability of water quality. For the above question
