Abstract

The invention relates to a preparation method of a river and lake mud solidification and stabilization agent, and belongs to the technical field of environment engineering. The preparation method comprises the following steps: preparing production raw materials comprising phosphogypsum, potassium dihydrogen phosphate and over-burnt magnesium oxide; drying and grinding the production raw materials; uniformly mixing the dried and ground production raw materials according to a mss ratio of phosphogypsum to potassium dihydrogen phosphate to over-burnt magnesium oxide of 1:1:2 in order to obtain the river and lake mud solidification and stabilization agent. The agent produced through the preparation method has the advantages of low treatment cost, high mud solidification intensity, good pollutant stabilization effect and low environment risk.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a method for preparing a solidification and stabilization agent for river and lake sludge. Background technique [0002] With the rapid development of urbanization in China, a large number of black and smelly rivers and lakes urgently need to be treated. The root of black and smelly river and lake governance lies in silt control. River and lake silt has the characteristics of high water content, high organic matter content, low permeability, large volume, and contains different levels of pollutants and garbage, which makes it difficult to deal with in the project and is prone to secondary pollution. Therefore, how to standardize system processing and disposal is the key problem currently facing. [0003] Solidification and stabilization treatment is the key to realizing resource utilization of river and lake sludge, and the choice of solidification and stabili...
