- 摘要:
- 河南黄河流域某污水厂规模为4×104 m3/d,采用组合式氧化沟工艺,提标工程要求出水主要污染物指标达到地表水准Ⅳ类标准和《河南省黄河流域水污染物排放标准》(DB 41/2087—2021)一级标准。针对进水以工业废水为主,水质波动大、浓度高的特点,综合考虑用地条件、停水周期、水力高程、消防要求、施工影响、节能降耗等因素,提标改造工程新建了厌氧池并改造氧化沟为A2O+MBBR池,且增加了臭氧(O3)氧化深度处理工艺,改造后各项出水水质均满足标准要求。设计中生物池加固采用池壁凿孔结构设计,悬浮风机房进风考虑有效过滤,并对高效沉淀池沉淀区进行了配水均匀性改造。
- Abstract:
- The process of a wastewater treatment plant with scale of 4×104 m3/d in the Yellow River basin of Henan Province was combined oxidation ditch. The main pollutant indexes in the effluent of the upgrading project are required to meet the class Ⅳ limit specified in the surface water standard and the first level limit specified in Discharge Standard of Water Pollutants in Henan Province Located in the Yellow River Basin (DB 41/2087-2021). The influent is mainly industrial wastewater, and the water quality is characterized by large fluctuation and high concentration. The upgrading project built a new anaerobic tank, transformed the oxidation ditch into A2O and MBBR tank, and added an ozone oxidation advanced treatment process based on comprehensive consideration of the factors such as land conditions, water cut-off period, hydraulic elevation, fire requirements, construction impact and energy saving and consumption reduction, and the effluent quality met the requirements specified in the discharge standard after the transformation. The design reinforced the biological tank with a perforated structure on the wall, considered the effective filtration of the air from the suspension fan room, and improved the uniformity of water distribution in the sedimentation area of the high efficiency sedimentation tank.
