Abstract

The invention provides a granular material for water area governance as well as a preparation method and application method thereof. The granular material comprises raw materials including the following components in percentage by mass: 70-90% of fly ash, 5-20% of cement, 2-10% of clay, 10-100ppm of biological enzyme and 15-30% of water, wherein the total mass percentage of the flay ash, the cement and the clay is 100%. The granular material has a particle size of less than 5cm, has a plurality of micropores, is relatively light, air-permeable and water-permeable, can be used for absorbing and inhibiting hydrogen sulfide, phosphate and ammonia nitrogen dissolved out from sludge at the bottom of a water area, degrading organic matters in water, purifying the water and forming a good microbial environment and an underwater flora and fauna biological environment, is simple in preparation process, wide in raw material source and low in cost, and has significant economic and social benefits.

Description

technical field [0001] The invention belongs to the field of water body control, and in particular relates to a granular material for water area control and a preparation and use method thereof. Background technique [0002] Sludge in lakes is a relic of the water purification process. It is an aggregate of acidic substances containing a variety of harmful components. Not only will it not cause too much harm to the water body when the stock is small, but it can also prevent lake water leakage like a layer of ultra-fine membrane. However, the existence of a large amount of sludge in the lake is an important factor leading to the eutrophication of the water body. At present, the main treatment methods are as follows: (1) Most of the domestic dredging methods are adopted, and the cost of mechanical labor is huge, because it is only a temporary reduction, and the subsequent repetition cannot be controlled. Moreover, the water body is seriously polluted during dredging, which c...
