- 摘要:
- 某城市污水處理廠一期設(shè)計規(guī)模為2×104 m3/d,采用傳統(tǒng)A2/O工藝,出水水質(zhì)很難達(dá)到《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》(GB 18918—2002)一級A標(biāo)準(zhǔn)。二期擴(kuò)建工程設(shè)計規(guī)模為3×104 m3/d,在總結(jié)一期工程運(yùn)行經(jīng)驗(yàn)基礎(chǔ)上,提出倒置A2/O+A/O工藝,并輔以化學(xué)除磷及接觸過濾等深度凈化處理工藝,確保出水穩(wěn)定達(dá)標(biāo)排放。二期擴(kuò)建工程投入運(yùn)營后,出水COD、SS、氨氮、TP平均濃度分別為34.5、7.8、3.8、0.34 mg/L,穩(wěn)定達(dá)到一級A排放標(biāo)準(zhǔn)。
- Abstract:
- The first-phase design capacity of a wastewater treatment plant was 2×104 m3/d. With the traditional A2/O process, the effluent quality was very difficult to meet the first class A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The design capacity of second-phase extension project was 3×104 m3/d, on the basis of operation experience of the first-phase project, the combination process of reversed A2/O+AO followed by the advanced treatment process of chemical phosphorous removal and contact filtration were adopted in ensure the stable effluent quality. After second-phase extension project was put into operation, the effluent concentrations of COD, SS, ammonia nitrogen, TP were 34.5 mg/L, 7.8 mg/L, 3.8 mg/L, 0.34 mg/L, respectively, and all effluent indexes could meet the first level A criteria.
