【摘要】 对西安某酒店的生活污水处理系统进行工艺设计、设备安装与系统调试。采用水解酸化与二级生物接触氧化结合的分散式污水处理工艺,稳定运行后对原污水中COD、BOD5、SS、NH3-N、TP的去除率分别为91.3%、94.1%、84.1%、75.8%、78.8%,出水水质满足《黄河流域(陕西段)污水综合排放标准》一级标准要求(DB 61/224—2011)。更多还原

【Abstract】 The technical design,equipment installation and system debugging of the domestic sewage treatment systems of a hotel have been accomplished. The results show that after the system runs steadily,the removing rates of COD,BOD5,SS,NH3-N and TP reach 91.3%,94.1%,84.1%,75.8% and 78.8%,respectively,by using the combined hydrolysis acidification and two-stage biological contact oxidation process of distributed sewage treatment technology. The treated effluent quality is in line with the relevant first class of Shaanxi Section of the Yellow River Basin Comprehensive Sewage Discharge Standard(DB 61/224—2011).更多还原
