Riverway sludge repairing material and preparation method thereof

Abstract

The invention relates to a riverway sludge repairing material and a preparation method thereof. The riverway sludge repairing material is prepared from, by weight, 15-25 parts of diatom ooze, 3-5 parts of disodium edetate dihydrate, 4-8 parts of calcium peroxide, 25-35 parts of carrier base material, 9-13 parts of compound flora, 4-6 parts of chitin, 5-7 parts of polyacrylamide, 10-15 parts of humus, 3-4 parts of sorbic acid and 100-120 parts of deionized water. The riverway sludge repairing material is easy to obtain, a fixed layer is formed on the surface of bottom sediment through biological breeding, the relation between a water source and sludge is effectively blocked, effective nutrients in the sludge are absorbed and released into the water source, heavy metal ions, sulfide and phosphide in the water source are effectively removed, the dissolve oxygen concentration in the water source is improved, the stink is eliminated, water quality is improved, aquatic plant growth is promoted, and restoration and development of a riverway ecosystem are accelerated.

Description

Technical field [0001] The invention relates to a river silt repairing material and a preparation method thereof. Background technique [0002] The black and odor of the river is mainly the result of the imbalance of oxygen supply and oxygen consumption in the water body caused by excessive pollution, especially the slow flow river, which has poor self-purification ability, and the water body is under anoxic or even anaerobic conditions for a long time. A large amount of retained pollutants are transformed and produced ammonia nitrogen, Malodorous substances such as hydrogen sulfide and volatile organic acids, and black substances such as iron and manganese sulfides. After the bottom mud is black and smelly, the output, transfer and purification of pollutants cannot be completed. The pollutants are seriously accumulated and a vicious circle, resulting in very serious internal pollution, resulting in a sharp deterioration of the bottom habitat, and a large number of deaths of fish...

AI Technical Summary

Problems solved by technology

After the bottom mud is black and smelly, the output, transfer and purification of pollutants cannot be completed, and the pollutants are seriously accumulated and vicious circle, resulting in very serious endogenous pollution, resulting in a sharp deterioration of the bottom habitat, a large number of fish and other aquatic animals die, sinking Aquatic plants such as water plants are difficult to survive, and the ecosystem is seriously degraded
