摘要
对目前国内规模最大的上海市白龙港污水处理厂污泥厌氧消化系统的运行情况进行了系统分析。该污泥厌氧消化系统的设计规模为204 tDS/d,于2011年5月完成启动调试,稳定运行后的产气量受进泥流量和性质的影响呈现较为规律的季节性变化,单位污泥实际年均产气量为10.73 m3/m3污泥,沼气产率为0.82 m3/kgVSS。厌氧消化系统运行中存在的较为突出的问题包括浮渣泡沫、鸟粪石结晶、池内积砂等,分析了其产生原因,并给出了相应的解决措施。
The operation of the sludge anaerobic digestion system in Bailonggang WWTP, which has the largest treatment capacity (204 tDS/d) in China, was analyzed. After a successful commissio- ning in May 2011, the biogas production of the sludge anaerobic digestion system showed regular seasonal variation owing to the fluctuation of incoming sludge flow rate and sludge characteristics. The actual an- nual average biogas production and biogas yield were 10.73 m3/m3 sludge and 0.82 m3/kgVSS, respec- tively. Scum and foam, struvite scaling and sand accumulation were major problems affecting the opera- tion of the sludge anaerobic digestion system. The corresponding recommendations were given based on analyzing the causes of the problems.
