Wastewater treatment agent for aquaculture

Abstract

The invention discloses a wastewater treatment agent for aquaculture. The wastewater treatment agent contains an ingredient A, an ingredient B, an ingredient C and an ingredient D, wherein the ingredient A is at least one of dicalcium phosphate, sodium dihydrogen phosphate, sodium selenite and magnesium sulfate; the ingredient B is at least one of DL-methionine, a L-lysine salt, tryptophane, threonine, betaine, astaxanthin, glucan, peptidoglycan, yeast and lipopolysaccharide; the ingredient C is at least one of sodium humate powder, sodium thiosulfate powder and aluminum potassium sulfate powder; and the ingredient D is at least one of glycyrrhiza uralensis, mung bean flour, acanthopanax bark, codonopsis pilosula, dried tangerine peel, Chuanxiong rhizome, gardenia, gypsum, dittany bark, folium isatidis, cortex phellodendri, radix isatidis, eupatorium fortunei and radix bupleuri. According to the wastewater treatment agent for aquaculture, through promoting the growth of plankton in culture water, the water treatment rate is accelerated, the self-purification ability of the water is improved, the improvement on water environment is promoted, influence on fishes in the water cannot be caused, and secondary pollution cannot be caused.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an aquaculture wastewater treatment agent. Background technique [0002] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country, and its aquaculture production has accounted for about 2 / 3 of the world's aquaculture production. However, most domestic aquaculture uses closed waters such as ponds and reservoirs. The self-purification ability is far lower than the eutrophication speed of the water body, and the water environment is greatly damaged. The same area cannot meet the sustainable development of aquaculture for a long time. The application of feed, the use of fungicides and disinfectants, and the accumulation of animal and plant carcasses and animal manure lead to a large accumulation of organic matter, nitrogen and phosphorus in the aquaculture water, resulting in the deterioration of the aquaculture water. According to t...

[0002] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country, and its aquaculture production has accounted for about 2/3 of the world's aquaculture production. However, most domestic aquaculture uses closed waters such as ponds and reservoirs. The self-purification ability is far lower than the eutrophication speed of the water body, and the water environment is greatly damaged. The same area cannot meet the sustainable development of aquaculture for a long time. The application of feed, the use of fungicides and disinfectants, the accumulation of animal and plant carcasses and animal manure lead to a large accumulation of organic matter, nitrogen and phosphorus in the aquaculture water, resulting in the deterioration of the aquaculture water body

According to the research, it is found that the ratio of feed to the total input of nitrogen and phosphorus in the pond is 76.08% and 98.55%, and the antibiotics in the long-term feeding feed can cause antibiotic-resistant bacteria in the animal body. These bacteria have different damages to humans and animals. At the same time, aquaculture The waste water has also caused great harm to the surrounding water environment and ecological environme
