Problems solved by technology

However, fly ash contains high water-soluble salts, and most of the heavy metals will be distributed in the fly ash, which accounts for 0.5% to 3% of the total waste incinerated after garbage incineration. It is a hazardous waste and must be handled properly, otherwise it will be Cause heavy metal migration, pollute groundwater, soil and air
The existing fly ash treatment chemicals are expensive, and the treatment methods are complicated and difficult to deal with

Embodiment Construction

[0012] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0013] The medicament for treating incineration fly ash consists of 3-5% of phosphorus-based compounds, 2-8% of strong alkali, 8-15% of polymerization terminators, 4-6% of sulfur-based compounds, 2-4 % of hydrazine hydrate and 62-81% of water are stirred evenly through a batching tank and then filled.

[0014] The polymerization terminator is one of sodium dimethyl dithiocarbamate, sodium polysulfide, and sodium nitrite or a plurality of them in any mass ratio.

[0015] The polymerization terminator can also be sodium d...

Abstract

The invention relates to a medicament for treating incineration fly ash, which comprises the following components in percentage by mass: 3-5% of a phosphorus compound, 2-8% of a strong base, 8-15% ofa polymerization terminator, 4-6% of a sulfur compound, 2-4% of hydrazine hydrates and 62-81% of water, and the elements are uniformly stirred and filled through a mixing tank. The medicament of the invention is made by mixing mature chemical raw materials, with low production cost, small treatment addition amount, stable treatment effect and long-term effectiveness, and the medicament can also beapplied to the treatment of the waste residues, sediment mud and polluted soil with excellent popularization value.

Description

technical field [0001] The invention relates to the field of pollution restoration, in particular to a medicament for treating incineration fly ash. Background technique [0002] With the rapid development of industrial and agricultural production and the continuous improvement of people's living standards, the generation of urban waste is also increasing. At present, the annual discharge of urban waste in my country has reached more than 150 million tons, and it is still growing at an annual rate of 8-10%. rate keeps increasing. Therefore, how to deal with such huge urban garbage reasonably and effectively has become an environmental protection problem to be solved urgently. [0003] Waste incineration has been widely used in recent years because of its obvious advantages of reduction, sterility, and resource utilization. However, fly ash contains high water-soluble salts, and most of the heavy metals will be distributed in the fly ash, which accounts for 0.5% to 3% of the...
