preparation example Construction

[0045] The second aspect of the embodiment of the present application provides a method for preparing a water-repellent enhancing liquid, including the following methods:

[0046] S01. Provide components according to the water-repellent enhancing liquid;

[0047] S02. dissolving the alkaline additive in water to obtain an alkaline solution;

[0048] S03. Performing a first mixing treatment on the water repellent agent and the alkaline solution to obtain a first mixed solution;

[0049] S04. The first mixed liquid is sequentially mixed with the reinforcing agent and the dispersant for the second mixing process, and then left to stand to obtain the water-repellent reinforcing liquid.

[0050] The preparation method of the water-repellent enhancing liquid provided in the second aspect of the present application only needs to mix the components sequentially. The preparation method is simple and fast, does not require large-scale equipment, and can be widely used.

Abstract

The invention relates to the technical field of solid pollutant resource utilization, in particular to water-repellent enhancing liquid as well as a preparation method and application thereof. Wherein the provided water-repellent enhancing liquid comprises a water repellent, an alkaline auxiliary agent, an enhancer and a dispersing agent which are compounded for use, and the synergistic effect of the water repellent and the alkaline auxiliary agent can activate active ingredients such as iron oxide, aluminum oxide, magnesium oxide and calcium oxide in the sludge raw materials to perform a cross-linking reaction to improve the strength, and is beneficial to killing bacterial viruses in the product; effective components in the sludge raw material can be activated to generate chemical reaction under the synergistic effect of the reinforcing agent and the dispersing agent, so that a compact structure is formed in the material, and the strength of the material is greatly improved. Meanwhile, the use of the water-repellent reinforcing liquid can react and slightly expand the sludge particles, and the water can be completely rejected from permeating the sludge particles after the water-repellent reinforcing liquid is dried, so that the strength of the sludge particles and products can be better ensured, a solid foundation is laid for the complete utilization of the sludge, and the wide application of the water-repellent reinforcing liquid is improved.

Description

technical field [0001] The application belongs to the technical field of resource utilization of solid pollutants, and in particular relates to a water-repellent enhancing liquid and its preparation method and application. Background technique [0002] Silt is a cohesive soil deposited in still water or slow flowing water environment, formed by biochemical action, with natural water content greater than liquid limit and natural void ratio greater than or equal to 1.5. Modern sediments are formed under the condition of microbial participation, rich in organic matter, usually gray-black in color; low in mechanical strength and strong in compressibility. Silt is a special soil with characteristics different from ordinary soil. The silty soft soil has a high water content, generally greater than 40%, and has rheological and thixotropic properties; the color is generally dark gray or dark green, and has an odor; the natural void ratio is greater than 1.0; it contains organic mat...
