摘要:向污水厂污水处理工艺段投加聚合氯化硫酸铁（PFS）,可在实现污水脱氮除磷的同时，显著降低污泥厌氧消化产生沼气中硫化氢的含量，脱硫效果明显优于传统的湿式和干式脱硫工艺。通过对比北方某污水厂污水处理系统投加PFS前后沼气中硫化氢含量的变化发现，沼气经传统的湿式和干式脱硫后硫化氢平均含量可由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，污泥消化所产生的沼气中硫化氢含量下降到100 mg/m3以下，最低达到48 mg/m3，沼气无需再经传统脱硫就可直接用于发电。
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.
