Composition and method for treating bottom sludge, and application

The invention provides a composition and a method for treating bottom sludge, and application. The composition comprises degradable materials and porous mineral particles. The degradable materials aremade from zeolite, calcium carbonate, bentonite and disinfectants by means of granulation. The composition, the method and the application have the advantages that odor of the bottom sludge in waterbodies can be eliminated by the aid of the composition and the method, the concentration of pollutants can be lowered by the aid of the composition and the method, the bottom sludge can be compressedand reduced in an in-situ manner by the aid of the composition and the method, and high-water-permeability hardening composite material matching process technologies and application for suspension bottom sludge can be implemented; the composition and the method can be implemented on the surfaces of the water bodies, adapt to operation in narrow and small spaces and are low in cost and easy to popularize and apply on a large
