生活垃圾焚烧发电飞灰处置方法

Disposal Methods of Fly Ash in Waste Incineration Power Generation

随着我国城镇化进程的加快,生活垃圾产生量也在增加,原有的垃圾填埋导致土地资源越来越紧缺,作为生活垃圾处理的另一主要途径——焚烧发电技术得到了较大的发展。该技术不仅能变废为宝,将生活垃圾转变为电能和热能,更能促进生活垃圾减量化,有效解决了“垃圾围城”现象,缓解了土地资源压力。但焚烧过程中会产生含有二噁英、重金属等有害物质的飞灰,若飞灰处置不当则会对周边环境造成危害。

With the acceleration of urbanization,the amount of garbage has increased and land resources are in short supply.As the main method of domestic garbage treatment,the technology of power generation by incineration of domestic garbage has been greatly developed.The development of this technology can not only turn domestic waste into treasure to produce electricity and heat,but also effectively solve the social problem of"garbage besieged city"by reducing the amount of domestic waste incineration,saving a lot of land resources for the society.However,the fly ash that contains harmful substances such as dioxins and heavy metals generated during the incineration of domestic waste will cause certain harm to the environment if it is not disposed of properly.
