城市生活垃圾渗滤液处理技术的研究

垃圾填埋过程中产生的成份复杂、高浓度的垃圾渗滤液,如果不加处理而直接排放,就会对大气,水体及土壤造成严重的污染,对人体健康造成严重危害.因此,寻求一种高效经济的垃圾渗滤液处理技术显得尤为重要.为此阐述了城市生活垃圾渗滤液的处理技术:生物处理法,物理化学法和其他方法.其中,生物处理法包括:好氧生物处理,厌氧生物处理,厌氧-好氧生物处理法;物理化学法包括:Fenton法,电解氧化法,光催化氧化法和等离子体处理技术;其他方法包括:土地处理法,回灌法和有效微生物(EM)法.

Studies on Treatment Technologies of Municipal Domestic Refuse Leachate

A great of complicate and high-concentrate organic wastewater would appear in the course of landfilling.The leachate will cause serious environment pollution if discharged without treatment,such as air pollution,water pollution and soil pollution,which may cause harmful to human health.Therefore,it was serious important to find a kind of economical and effective treatment for municipal domestic refuse leachate.Several treatment technologies for landfill leachate are summarized and analyzed,for example,biological treatment,physical-chemical treatment and others.Aerobic biological treatment,anaerobic biological treatment and combing Anaerobic-Aerobic biological were introduced in biological treatment;Fenton reagent,electrolytic oxidation,photocatalytic oxidation,plasma technology were recommend in physical-chemical treatment.Other treatment also presented including soil treatment,recirculation treatment and effective microorganism.
