Embodiment 1

[0026] The accelerated stabilization of the domestic waste landfill obtained in this example is implemented according to the following steps:

[0027] (1) The required concentration of chloroform and alkaline washing powder (Tide washing powder, item number 690314801922) are prepared in the quantitative domestic garbage leachate. In the "CSISC Brand Reputation Research Report", its quality and health are lower than the same price. The product is in the forefront), stir evenly, and obtain the accelerated stabilization reagent, wherein the mass ratio of the added amount of chloroform and the added amount of the leachate is 2.0:2000, and the alkaline washing powder and the leachate are dissolved and mixed according to the mass ratio of 5.0:2000 .

[0028] (2) Trichloromethane: alkaline washing powder: aged leachate: domestic waste in a mass ratio of 2.0:5.0:2000:10000; after mixing according to the proportion, simply throw and mix evenly.

[0029] (3) The domestic garbage heap a...

Abstract

The invention discloses an accelerated stabilization reagent for domestic waste in landfill, which is characterized in that it comprises: leachate, chloroform and alkaline washing powder, wherein the mass of the added amount of chloroform and domestic waste leachate is The ratio is 0.5:2000-2.0:2000, and the mass ratio of the added amount of alkaline washing powder to leachate is 2.0:2000-5.0:2000. The invention also discloses its preparation method. The invention utilizes the accelerated reduction effect of washing powder / chloroform on garbage, accelerates stabilization and increases landfill volume, and has certain technical support for increasing landfill storage capacity and circular landfill.

Description

technical field [0001] The invention belongs to the technical field of garbage disposal, and in particular relates to an accelerated stabilization agent for domestic garbage in a landfill and a use method thereof. Background technique [0002] In the domestic waste incineration and landfill treatment process, the landfill has the advantages of low construction investment and operation cost, and is also the main disposal method of domestic waste in my country at present. [0003] Since the garbage classification system in my country is not perfect, the domestic garbage entering the landfill contains a high proportion of perishable organic matter, which first degrades with the increase of landfill time, which is also reflected in the overall degradation and stabilization of the landfill garbage. According to the research results of scholars, the time required for the complete stabilization of the landfill is 8 to 10 years. [0004] At this time, the settlement of the landfill...
