Abstract

The invention discloses a sludge reducing agent. The sludge reducing agent comprises the following components in parts by mass: 8-15 parts of cow dung, 8-15 parts of sheep manure, 8-15 parts of straw,8-15 parts of vinasse, 8-15 parts of bean pulp, 8-15 parts of bits of wood, 10-15 parts of superphosphate, 1-5 parts of molasses, 5-10 parts of humic acid, 1-5 parts of maple leaf powder, 1-5 parts of bacillus, 1-5 parts of lactic acid bacteria, 1-5 parts of zymophyte, 1-5 parts of photosynthetic bacteria, and 10-20 parts of one or combination of shell powder and oyster powder. The sludge reducing agent is capable of reducing the sludge accumulation rate and improving the water purifying capacity; the benthos reproductive rate and the waterweed growing rate are greatly improved; the ecological environment of the bottom of a pool is optimized; and ammonia nitrogen and nitrite are effectively prevented from exceeding the standard.

Description

technical field [0001] The invention relates to a sludge reducing agent and a preparation method thereof. Background technique [0002] Silt is unconsolidated soft fine-grained or very fine-grained soil that is deposited in still water or slow flowing water environment and formed by physical, chemical and biochemical actions. Whether it is a river, a lake or a culture pond, silt will form at the bottom. Silt is an indispensable part of rivers and lakes, a storehouse of nutrients and salts in water bodies, and an ideal habitat for detritus organisms, which is conducive to maintaining the self-purification ability of water bodies. However, too much silt will lead to excessive accumulation of organic matter in the water body, resulting in eutrophication of the water body, corruption and blackening of the water quality, and even the outbreak of blue-green algae and other hazards. Contents of the invention [0003] The object of the present invention is to provide a silt redu...
