Gelatinization sintering treatment method of waste incineration fly ash and waste treatment method

Abstract

The invention discloses a gelatinization sintering treatment method of waste incineration fly ash. The gelatinization sintering treatment method of waste incineration fly ash comprises the following steps: S1, performing sintering pretreatment on the waste incineration fly ash so as to form solidified fly ash; S2, conveying the solidified fly ash into an incinerator used for incinerating household wastes, and performing sintering treatment on the solidified fly ash so as to generate accumulated waste incineration fly ash. According to the gelatinization sintering treatment method of waste incineration fly ash, the incinerator used in waste incineration is utilized for sintering, the waste incineration fly ash and the household wastes are conveyed into the incinerator together for combustion, sintering conditions and equipment are not needed to be additionally set, technical problems are not needed to be additionally overcome, the cost is low, the flow path is short, the operation is convenient, and the method is convenient in construction and large-range engineering application; in addition, when the waste incineration fly ash is subjected to a gelatinization sintering process, after heavy metals and dioxin in the waste incineration fly ash are subjected to high-temperature sintering, slags in the incinerator have stable physical properties, cannot pollute environment and can be recycled.

Description

technical field [0001] The invention relates to the technical field of environmental protection and hazardous waste treatment, in particular to a gelling and sintering treatment method for waste incineration fly ash and a waste treatment method. Background technique [0002] With the rapid increase of population and the improvement of living standards, domestic garbage has increasingly become an important issue affecting the environment of our country. Waste incineration has become one of the common methods of domestic waste treatment due to its advantages of high efficiency, rapid capacity reduction, and high energy utilization rate. However, the waste incineration fly ash produced by waste incineration contains a large amount of heavy metals and organic pollutants. It is a hazardous waste (No. HW18) stipulated in the "National Hazardous Waste List" and must be stabilized before final treatment. [0003] Waste incineration fly ash is the reaction product of dust carried by...
