摘要
山东省桓台县污水处理厂采用百乐克工艺(Biolak)进行提标改造,出水水质可达到《城镇污水处理厂污染物排放标准(》GB 18918—2002)的一级A标准,介绍了改造背景、工艺设计方案选择、工程实施效果等。结果表明,本次提标改造选用的生物处理工艺可行,出水COD、BOD5、NH3-N等均达到了处理要求,由于原水的C/N值偏低,反硝化时间虽较长,TN稳定达标仍有一定难度。
Biolak process was used in upgrading and retrofitting of WWTP in Huantai County, Shandong Province. The upgrading background, choice of process design scheme, practice of the engi- neering and so on were introduced. The results showed that the biological treatment process used in the upgrading and retrofitting was feasible, and the effluent COD, BOD5 and NH3 - N all met the treatment requirements. Although the denitrification time was long, the TN hardly met the discharge standard due to low C/N ratio of the influent.
