Method for disposing sludge at the bottom of fishpond

Abstract

The invention discloses a method for disposing sludge at the bottom of a fishpond and relates to the technical field of aquaculture. The method comprises the steps of obtaining a combustion product of the mixture of bamboo, wood and corn straw, mixing the combustion product with silicate, quick lime, pleurotus eryngii slags, freeze-dried lactic acid bacteria powder, saccharomycetes powder, monopotassium phosphate, alums and sodium hypochlorite, adding the mixture into a ball mill, and conducting ball milling on the mixture into powder materials of 300 mesh; adding 20% beer mash into brewer's grains, putting the mixture of the beer mash and the brewer's grain into a vat, adding rainwater into the vat, conducting open fermentation for seven days, and obtaining the brewer's grains which are subjected to fermentation treatment; spreading the powder materials all over the bottom of the fishpond, and airing the powder materials from one to three days until the surface of the sludge at the bottom of the fish pond is dry; conducting dilution by adding water into the brewer's grains which are subjected to the fermentation treatment until the weight of the brewer's grains is doubled, spreading the diluted brewer's grains all over the fishpond until the bottom of the fishpond is all wet, adding new water to the fishpond next day, and conducting standing from five to seven days. According to the method, after the new water is added, the beneficial bacteria in the fishpond and the plants required by the growth of fishes can be recovered rapidly.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a treatment method for sludge at the bottom of fish ponds. Background technique [0002] Without water, there will be no life, and there will be no human beings. However, with the increase of the social population, the demand for life is increasing, and the emissions are also increasing. Therefore, people need food for life, and food production requires pesticides and chemical fertilizers. A large number of chemical fertilizers and pesticides are used to increase production and harvest. Excessive use of chemical fertilizers and pesticides causes water pollution. Toxic and harmful substances such as arsenic, cadmium, and cyanide in pesticides flow into ditches, ponds, dams, and rivers and lakes when it rains. , pollute water resources, make green water smelly, cause fish and shrimp not to grow, spread harmful microorganisms, produce germs and viruses, pollute the ecological en...

[0002] Without water, there will be no life, and there will be no human beings. However, with the increase of the social population, the demand for life is increasing, and the emissions are also increasing. Therefore, people need food for life, and food production requires pesticides and chemical fertilizers. A large number of chemical fertilizers and pesticides are used to increase production and harvest. Excessive use of chemical fertilizers and pesticides causes water pollution. Toxic and harmful substances such as arsenic, cadmium, and cyanide in pesticides flow into ditches, ponds, dams, and rivers and lakes when it rains. , pollute water resources, make green water smelly, cause fish and shrimp not to grow, spread harmful microorganisms, produce germs and viruses, pollute the ecological environment, and bring safety hazards to people's domestic water; people need living utensils, transportation and accommodation, etc., need Mining and factory production, factory production, and mine mining, a large amount of heavy metals flow into the water body, polluting water resources; the tailings extracted from the metal ore are piled up and stored improperly, and the remaining heavy metals in the tailings that have not been quenched will also be released when it rains. Rainwater flows into rivers and lakes, causing heavy metals in the water to exceed the standard and causing pollution

[0003] Therefore, at present, the situation of water pollution is increasing day by day, especially in the current rural water bodies, because there are a large number of fish ponds in the countryside, there will be such problems in these fish ponds, and long-term pollution will lead to eutrophication of water bodies , leading to ecological balance
