Problems solved by technology

[0002] In recent years, calcium nitrite is an inorganic chemical product, which is an antifreeze component in antifreeze and water reducer. However, in the preparation of calcium nitrite, a large amount of waste residues will be produced. These waste residues have no value for reuse. If a large amount Long-term accumulation of waste slag pollutes the surrounding environment and also seeps into the ground, polluting groundwater
The output of waste slag is increasing every year, but there is no substantial progress in the project to deal with waste slag, and the environmental pollution needs to be solved urgently

Abstract

The invention relates to a waste residue treatment method. Waste residues are produced in the preparation of calcium nitrite. The waste residue treatment method disclosed by the invention is environmentally friendly, pollution-free, simple in operation process, and low in cost; and products prepared by firing can be reused, so that the method has good economic benefits, and is suitable for being widely popularized and applied.

Description

technical field [0001] The invention relates to a method for treating waste slag. Background technique [0002] In recent years, calcium nitrite is an inorganic chemical product, which is an antifreeze component in antifreeze and water reducer. However, in the preparation of calcium nitrite, a large amount of waste residue will be produced. These waste residues have no value for reuse. If a large amount The long-term accumulation of waste slag pollutes the surrounding environment and also seeps into the ground, polluting groundwater. The output of waste slag is increasing day by day, but the engineering of waste slag treatment has not made substantial progress, and the environmental pollution needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a method for treating waste residue. [0004] The technical scheme that realizes the object of the present invention is: a kin...
