A heavy metal stabilizer with water-reducing and flocculating properties and preparation method thereof

Abstract

The invention discloses a heavy metal stabilizer with a water-reduction property and flocculability and a preparation method thereof. The heavy metal stabilizer comprises the following raw materials of dithiocarbamate, dithio amino-acetate, ethyl xanthate, allyl alcohol polyoxyethylene ether, isoamyl alcohol polyoxyethylene ether, isobutyl alcohol polyoxyethylene ether, hydroxyethyl acrylate, polyacrylamide, sodium ammonium triacetate, saccharose and sodium polyacrylate. The heavy metal stabilizer has the water-reduction property and the flocculability, through the water-reduction and flocculation effects, the dosage of the stabilizer is reduced, and various metal can be simultaneously treated, secondary pollution does not occur to the environment, harmless treatment cost of waste incineration flying ashes can be remarkably reduced, and the usage amount can be reduced above 30 % relative to other organic chelating agents. Apparent color of the heavy metal stabilizer is changed along with changing of the dosage of all components, but the practical effect of the heavy metal stabilizer is not affected.

Description

technical field

[0001] The invention relates to the technical field of environmental engineering, in particular to a heavy metal stabilizer with water-reducing and flocculating properties and a preparation method thereof. Background technique

[0002] Domestic waste treatment and disposal is one of the important topics in the field of environmental engineering and environmental sanitation. At present, the disposal methods of domestic waste include sanitary landfill, aerobic composting, anaerobic fermentation, pyrolysis, and incineration, among which sanitary landfill is the most common application. The sanitary landfill of domestic waste has the advantages of low cost and simple operation. However, with the sharp increase in the generation of domestic waste, the site selection of landfill and its potential secondary pollution risks have been greatly challenged. The incineration method is a new way to reduce, harmless and recycle domestic waste, and it has been more and more...
