Embodiment Construction

[0017] The application of N-benzoyl-N-phenylhydroxylamine as a stabilizer for domestic waste incineration fly ash treatment and its application effect will be described in detail below with reference to the accompanying drawings.

[0018] 1. Composition analysis of domestic waste incineration fly ash

[0019] The incineration fly ash used in this embodiment is the domestic waste incineration fly ash of a certain waste incineration plant in Southwest China. The sampling and sample preparation techniques of the research samples are determined in accordance with Appendix A of the national standard GB5086.1-2007 and the industry standard HJ / T 20-1998. The freshly taken fly ash needs to be dried in an oven at 105°C to constant weight because it contains a small amount of water. The composition of incineration fly ash is based on USEPA3050 using HNO 3 -HF-HCl 4 After the fly ash is digested by the method, it is obtained by analyzing it with a 6410 flame photometer. The results a...

Abstract

The invention discloses an application of using N-benzoyl-N-phenylhydroxylamine as a stabilizing agent in domestic waste incineration fly ash treatment. The N-benzoyl-N-phenylhydroxylamine is efficient, stable, cheap, and easy to get, and has the advantages of less amount, simple stabilizing treatment method, low cost and no secondary pollution for heavy metal in domestic waste incineration fly ash. A leaching concentration of the heavy metal in a fly ash stabilizing product accord with a provision about leaching toxicity of dangerous wastes, and has better anti-acid properties. The stability effect is obviously influenced when a pH is lower than 3. The invention provides a low-cost method in the domestic waste incineration fly ash treatment to remove an important barrier for limiting the cleaning development of a rubbish incineration enterprise. Not only can the large environmental benefits be obtained, but also the obvious social effects and the good social effects can be obtained.

Description

technical field [0001] The invention belongs to the technical field of waste incineration fly ash stabilization treatment and relates to the application of N-benzoyl-N-phenylhydroxylamine as a stabilizer for domestic waste incineration fly ash treatment. Background technique [0002] At present, developed countries such as Japan, the United States, Germany, Switzerland and Canada widely use incineration to deal with municipal solid waste. Because waste incineration technology can effectively destroy organic toxic substances, greatly reduce the volume of waste, and can recover energy, it will become an important development direction of waste resource, harmless and volume reduction treatment technology in China. [0003] After garbage incineration, incineration fly ash equivalent to 3-5% of the original garbage weight will be produced, which is the residue collected in the flue gas purification system and heat recovery system. Incineration fly ash contains heavy metals such ...
