摘要:向污水廠污水處理工藝段投加聚合氯化硫酸鐵（PFS）,可在實(shí)現(xiàn)污水脫氮除磷的同時(shí)，顯著降低污泥厭氧消化產(chǎn)生沼氣中硫化氫的含量，脫硫效果明顯優(yōu)于傳統(tǒng)的濕式和干式脫硫工藝。通過對比北方某污水廠污水處理系統(tǒng)投加PFS前后沼氣中硫化氫含量的變化發(fā)現(xiàn)，沼氣經(jīng)傳統(tǒng)的濕式和干式脫硫后硫化氫平均含量可由7 696 mg/m3降至1 476 mg/m3；向MSBR池中投加19.13~24.60 mg/L的PFS后，污泥消化所產(chǎn)生的沼氣中硫化氫含量下降到100 mg/m3以下，最低達(dá)到48 mg/m3，沼氣無需再經(jīng)傳統(tǒng)脫硫就可直接用于發(fā)電。
Abstract:Dosing of polychloride ferric sulfate(PFS) in sewage treatment process could significantly reduce the content of hydrogen sulfide (H2S) produced in sludge anaerobic digestion while achieving denitrification and phosphorus removal, and the desulfurization effect was better than the traditional wet and dry desulfurization process. By comparing the content of H2S produced by sludge digestion before and after adding PFS to the sewage treatment system of a sewage treatment plant in North China, it was found that the content of H2S in biogas could be averagely reduced from 7 696 mg/m3 to 1 476 mg/m3 after traditional wet and dry desulfurization. After adding 19.13-24.60 mg/L of PFS to the MSBR, the content of H2S in biogas produced by sludge digestion could be reduced to below 100 mg/m3, and the lowest was 48 mg/m3, indicating that the biogas could be directly used for power generator without traditional desulphurization.
