摘要:- 北方某污水处理厂一期设计规模为50×104 m3/d，设计出水水质执行国家一级A标准，需要提标至《子牙河流域水污染物排放标准》（DB 13/2796—2018）中重点控制区排放限值标准。该污水厂采用移动床生物膜反应器（MBBR）工艺进行升级改造，改造后生化池出水COD、TP、NH4+-N、TN分别为（16.2±3.9）、（0.2±0.2）、（0.18±0.1）、（8.1±2.2） mg/L。改造后出水水质稳定优于设计排放标准，原水碳源利用率提高了63.14%，减少了36.5%的外碳源投加量和43.4%的聚合氯化铝（PAC）投加量。系统中的优势硝化菌属为Nitrospira，其在生物膜中的相对丰度达到7.31%，是活性污泥中的6.5倍。基于MBBR的原位改造实现了系统脱氮与除磷能力的同步提升，保障了出水水质的稳定达标，同时降低了运行费用。
Abstract:- The design capacity of the phase Ⅰ project of a wastewater treatment plant in northern China is 50×104 m3/d. The effluent quality is designed to meet the first level A criteria specified in the national discharge standard, but it needs to be upgraded to comply with the discharge limit for key control areas as specified in Ziya River Basin Water Pollutants Discharge Standards (DB 13/2796-2018). The project employed the moving bed biofilm reactor (MBBR) process for its upgrade and transformation. After transformation, the chemical oxygen demand, total phosphorus, ammonia nitrogen and total nitrogen in the effluent from the biochemical tank were (16.2±3.9) mg/L, (0.2±0.2) mg/L, (0.18±0.1) mg/L and (8.1±2.2) mg/L, respectively. In addition, the effluent quality was stable and better than the design discharge standard. The utilization rate of the carbon source in the raw water increased by 63.14%, while the dosage of external carbon sources and polyaluminum chloride (PAC) was reduced by 36.5% and 43.4%, respectively. The predominant nitrifying bacteria in the system was Nitrospira, with a relative abundance of 7.31% in the biofilm, which was 6.5 times higher than that in the activated sludge. The MBBR-based in-situ transformation achieved concurrent enhancement of the system’s nitrogen and phosphorus removal capabilities, ensured stable and compliant effluent quality, and reduced operation costs.
