摘要:- 北方某污水處理廠一期設(shè)計規(guī)模為50×104 m3/d，設(shè)計出水水質(zhì)執(zhí)行國家一級A標(biāo)準(zhǔn)，需要提標(biāo)至《子牙河流域水污染物排放標(biāo)準(zhǔn)》（DB 13/2796—2018）中重點控制區(qū)排放限值標(biāo)準(zhǔn)。該污水廠采用移動床生物膜反應(yīng)器（MBBR）工藝進行升級改造，改造后生化池出水COD、TP、NH4+-N、TN分別為（16.2±3.9）、（0.2±0.2）、（0.18±0.1）、（8.1±2.2） mg/L。改造后出水水質(zhì)穩(wěn)定優(yōu)于設(shè)計排放標(biāo)準(zhǔn)，原水碳源利用率提高了63.14%，減少了36.5%的外碳源投加量和43.4%的聚合氯化鋁（PAC）投加量。系統(tǒng)中的優(yōu)勢硝化菌屬為Nitrospira，其在生物膜中的相對豐度達到7.31%，是活性污泥中的6.5倍�；贛BBR的原位改造實現(xiàn)了系統(tǒng)脫氮與除磷能力的同步提升，保障了出水水質(zhì)的穩(wěn)定達標(biāo)，同時降低了運行費用。
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.
