Problems solved by technology

[0007] But the purification method of bottom mud that carries out now is to only use the method of dredging to carry away the bottom mud, and only use the method of carrying away to make the ecological system in the water be destroyed, for example just like seeing the fire prevention of the circulation of no ecological system like the water in the water tank

Embodiment 1

[0018] In the process of releasing the bottom mud of lakes, bays, rivers, etc. obtained by dredging, an inorganic electrolytic coagulant is added to the released bottom mud, and at the same time, a mixture of sodium silicate as a soil particle strengthening agent and a pH value adjusting agent is added. An aqueous solution of calcium carbonate, which can transform the soil.

[0019] In addition, the mixed water generated in this process can be clarified in turn and released.

Embodiment 2

[0020] Embodiment 2 Store the bottom mud obtained by the above-mentioned same dredging in a natural sedimentation tank, and after standing in the natural sedimentation tank for 2-3 hours, the floating water on the surface is clarified and released. Thereafter, the above-mentioned inorganic electrolytic coagulant is added to the bottom mud, and then an aqueous solution mixed with sodium silicate as a soil particle strengthening agent and calcium carbonate as a pH value adjusting agent is added to reform the soil.

[0021] Table 2 shows the addition amount of inorganic electrolytic coagulant, soil particle reinforcing agent and pH value adjusting agent to be added per 1 ton of bottom mud.

Abstract

The invention relates to an inorganic electrolytic coagulant and a soil reconstruction method using the inorganic electrolytic coagulant. Mix phosphonic acid and magnesium sulfate in a chlorine-free solvent and stir for several minutes, then mix aluminum sulfate and polyferrous sulfate, and stir for several minutes to obtain an inorganic electrolytic coagulant. The inorganic electrolytic coagulant and soil particle enhancer and pH The aqueous solution mixed with the regulator is added to the polluted bottom mud of lakes, bays, and rivers obtained by dredging, thereby changing the bottom mud into good soil.

Description

technical field [0001] The invention relates to an inorganic electrolytic coagulant capable of turning polluted bottom mud of lakes, marshes, bays, rivers, etc. into soil with excellent hydrophobicity, water retention and air permeability, and a soil improvement method using the inorganic electrolytic coagulant. Background technique [0002] Phosphorus, nitrogen, organic matter, sludge and other eutrophic salts and their undecomposed products are deposited in the bottom mud of lakes, bays, rivers, etc. The bottom mud increases oxygen consumption and reduces DO. [0003] At this time, the aquatic ecosystem is unbalanced, the self-purification ability of nature no longer exists, and the bottom mud becomes sulfide. Using it as an energy source produces various plankton and microalgae, which accelerates the deterioration of water quality. [0004] Bottom mud, also known as humus mud, contains a large number of corpses of insects, fish, algae, aquatic plants, etc., as well as fe...
