摘要
某水质净化厂原设计规模为2×104 m3/d,出水仅为二级出水标准。在充分挖潜现状构筑物处理能力的同时,将该厂进行提标改扩建,设计规模提升至4×104 m3/d,生化处理部分采用"A2/O+IFAS+二沉池"工艺及"高效沉淀池+生物曝气滤池",深度处理采用同一套工艺,水厂出水水质达到北京《水污染物综合排放标准》DB11/307—2013中一级B标准。水厂在运营中存在A2/O+IFAS池及臭氧接触池液位高于设计液位的问题,通过改进,液位达到设计要求。
The original design scale of a water purification plant is 2×10^4 m^3/d, and the effluent is only the secondary effluent standard.The reconstruction and expansion of the water purification plant was carried out based on fully exploiting the processing capacity of the current structure. The design scale was upgraded to 4×10^4 m^3/d. The biochemical treatment part of the water plant adopts"A2/O+IFAS" process and "high-efficiency sedimentation tank + bio-aeration filter". Advanced processing uses the same process. The effluent quality of the water plant reaches the first-class B standard in Beijing’s "Water Pollutant Comprehensive Emission Standard" DB11/307-2013. In the operation of the water plant, there was a problem that the liquid level of the A2/O+IFAS pool and the ozone contact pool was higher than the design liquid level. Through improvement, the problem has been solved.
