Abstract

The invention discloses a desulfurization wastewater peptizer as well as a preparation method and an application thereof. The desulfurization wastewater peptizer comprises the following components inparts by mass: 30-60 parts of a carboxylic acid polymer, 20-45 parts of liquid water glass, 6-18 parts of a regulator, 1-5 parts of liquid caustic soda and 1-10 parts of water. The desulfurization wastewater peptizer is prepared by the following method: mixing liquid sodium silicate, liquid caustic soda, a part of regulator and water, and uniformly stirring; and then sequentially adding the carboxylic acid polymer and the rest of the regulator in a stirring state, and uniformly mixing to obtain the desulfurization wastewater peptizer. The desulfurization wastewater peptizer disclosed by the invention is wide in raw material source, low in price, green and environment-friendly, and can be used for recycling desulfurization wastewater to prepare slurry with good viscosity and thixotropy. Theinvention overcomes the problem of failure of the conventional peptizer in desulfurization wastewater, can effectively treat desulfurization wastewater, has favorable economic and environmental benefits, and has favorable application prospects.

Description

technical field [0001] The invention belongs to the technical field of ceramic industry and fine chemical industry, and in particular relates to a gel debonding agent for desulfurization waste water and its preparation method and application. Background technique [0002] Desulfurization wastewater contains impurities such as suspended solids, supersaturated sulfites, sulfates, and heavy metals, many of which are the first category of pollutants that require strict control in the national environmental protection standards. Desulfurization wastewater has complex components and is difficult to treat. It requires equipment, treatment agents, energy, etc., takes up a large area, takes a long time to process, and has high overall costs. Commonly used desulfurization wastewater treatment technologies include settling tanks, chemical sedimentation, biological treatment, and zero-discharge technologies (evaporation pools, complete circulation, mixing with fly ash, etc.). Among the...
