陈 海, 王 玥, 刘东海(大连市市政设计研究院有限责任公司,辽宁大连116011) : 大连市夏家河污泥处理厂采用污泥厌氧发酵/工业化生物制气处理工艺,处理规模为600t/d。运行实践表明,该处理工艺不仅符合我国现有国情,污泥处理成本低,也能够使处理后的污泥达到国家环境保护部关于污泥“减量化、稳定化、无害化、资源化”的要求,而且遵循循环经济的理念,使污泥变废为宝,每年产生664.3×104m3沼气、4000t鸟粪石、4×104t优质腐殖土,同时减少排放温室气体6.18×104t,进而使污泥得到充分的综合利用。 : 污泥处理; 污泥厌氧发酵/工业化生物制气工艺; 沼气:X703.1 :C :1000-4602(2010)12-0042-04ProcessDesignandOperationExperienceofXiajiaheWWTPinDalianCityCHENHai, WANGYue, LIUDong-hai(DalianMunicipalDesignandResearchInstituteCo.Ltd.,Dalian116011,China) Abstract: DalianXiajiaheWWTPadoptssludgeanaerobicfermentation/industrializedbiogaspro-ductionprocesswithacapacityof600t/d.Theoperationpracticeshowsthatthecombinedprocessac-cordswithChineseconditions,haslowsludgetreatmentcostandenablesthetreatedsludgetomeettherequirementsofMEPforsludgereduction,stabilization,innocuity,reclamationandreuse.Byfollowingtheconceptofcirculareconomy,thesludgeisturnedfromtrashintotreasure.Thebiogasof664.3×104m3,struviteof4000tandhighqualityhumusof4×104tareproduced,andthedischargeofgreenhousegasesof6.18×104tisreducedannually.Thefullcomprehensiveuseofsludgeisachieved.
