摘要:
天津某沿海污水处理厂规模为10×104 m3/d，进水含盐量较高，2017年进行提标改造，要求出水水质稳定达到天津市地方标准《城镇污水处理厂污染物排放标准》（DB 12/599—2015）A标准。污水厂面临进水全盐量高抑制生物系统、生化池反硝化脱氮能力不足及占地受限、进水水温较低抑制硝化、难降解有机物含量较高使COD达标困难等问题。选择改良Bardenpho-MBBR工艺对生化池进行原位升级改造，以强化系统脱氮效果，同时提高生化段对高盐废水的抗冲击能力；选择新建臭氧催化氧化系统，以提高对难降解有机物的去除能力。改造后污水厂出水水质稳定达标，系统脱氮能力大幅提升，出水TN和氨氮分别低于8.0 mg/L和1.5 mg/L，COD稳定低于30 mg/L，应用效果良好。
Abstract:
The treatment capacity of a coastal wastewater treatment plant (WWTP) in Tianjin is 10×104 m3/d, and the influent contains high salinity. In 2017, upgrading and reconstruction of the WWTP was carried out, and the effluent water quality was required to meet level A limitations of Tianjin local Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (DB 12/599-2015). The WWTP faced with problems as follows: high influent total salinity inhibiting biological system, poor denitrification capacity of biochemical tanks with limited footprint, low influent water temperature inhibiting nitrification, high content of refractory organic matter and difficulty in meeting COD discharge limitation. The modified Bardenpho-MBBR process was selected to upgrade the biochemical tank in situ to strengthen the denitrification performance of the system and improve the impact resistance of the biochemical section to high salinity wastewater. A new ozone catalytic oxidation system was selected to improve the removal ability of refractory organic matter. After the reconstruction, all the control indexes reached the discharge limitations stably, and the denitrification capacity of the system was greatly improved. TN and ammonia nitrogen in the effluent were less than 8.0 mg/L and 1.5 mg/L, respectively, and COD was always less than 30 mg/L, indicating that good removal performance was obtained.
