Problems solved by technology

(2) The water color is normal but the pH is high, which mostly occurs in the early stage of breeding, mainly due to aging ponds, excessive nitrogen-containing organic matter at the bottom of the pond, and low buffering capacity of the water body
(3) Harmful algae (cyanobacteria or dinoflagellates) overgrow, the water color is blue or soy sauce, and the pH changes greatly
[0003] To sum up, there are currently several treatment plans for aquaculture water bodies, but according to the effect of treatment, there are still many sequelae, such as: preparation residues, which have a certain poisonous effect on the aquaculture objects, and the aquaculture objects die while the dissolved oxygen content is reduced. Phenomenon
Faced with such a problem, a large number of studies have found that due to the large amount of feed residues in the aquaculture water, the hydrophobicity of organic pollutants in animal excrement, and the organic matter may be strongly adsorbed on the surface of suspended particles or enter the soil pores of the bottom mud, Reduce the concentration of organic matter in the aqueous solution, resulting in the isolation of microorganisms and organic pollutants
Microbial degradation of organic matter ceases or slows down due to the inability of microorganisms to utilize the organic matter at very low concentrations
Therefore, the decisive factor affecting the degradation of organic matter in the bioremediation of aquaculture water is the low water solubility of organic matter, which limits its bioavailability

Embodiment 1

[0020] In a certain fish farm, use this activating agent when carrying clear ponds with water, specifically as follows: use the quantity of 6-8 kilograms of the described composite functional surfactant according to the water depth of 1 meter per mu, spread the described composite functional surfactant Sprinkle the whole pond. Generally, the fish can be released after 7-8 days after clearing the pond and the potency of the medicine disappears. This method does not need to add new water, which prevents the danger of pests and diseases and wild fish being brought into the pond with the water, and the disease prevention effect is better than that of ordinary clearing ponds (such as quicklime clearing ponds).

[0021]A compound functional surfactant for regulating the environment of aquaculture water body, the components include: trace element small peptide chelate, 2,2-dibromo-3-nitrilopropionamide (DBNPA), lumbrokinase, the trace element Small peptide chelate, 2,2-dibromo-3-nit...

Embodiment 2

[0036] In a certain fish farm, use this active agent when drying ponds and clearing ponds, as follows: first drain the pond water or leave 6-9 cm of water, and use 25-30 kg of this active agent per mu and depending on The amount of sludge at the bottom of the pond will increase or decrease, and the active agent will be evenly spread over the whole pond. In the early morning of the next day, it is best to rake the pond mud with a long-handled mud rake to give full play to the disinfection effect of the active agent. Generally, the fish can be released after the drug effect disappears within 7-8 days. When adding new water, in order to prevent pests and wild fish from entering the pond with the water, filter measures should be taken when adding water. Whether it is a clear pond with water or a clear pond with dry ponds, after passing through such a clear pond, it will kill germs, aquatic insects, crabs, shrimps, leeches, snails, tadpoles, green mud moss, wild fish, Parasites a...

Embodiment 3

[0049] In a certain fish farm, use this activating agent when carrying clear ponds with water, specifically as follows: use the quantity of 30-35 kilograms of the described composite functional surfactant according to the water depth of 1 meter per mu, spread the described composite functional surfactant Sprinkle the whole pond. Generally, the fish can be released after 7-8 days after clearing the pond and the potency of the medicine disappears. This method does not need to add new water, which prevents the danger of pests and diseases and wild fish being brought into the pond with the water, and the disease prevention effect is better than that of ordinary clearing ponds (such as quicklime clearing ponds).

[0050] A composite functional surfactant for regulating the environment of aquaculture water, characterized in that the components include: small trace element peptide chelates, 2,2-dibromo-3-nitrilopropionamide (DBNPA), lumbrokinase, and The above-mentioned trace elemen...

Abstract

The invention discloses a method and a composite surfactant for regulating and controlling an aquatic water environment. The composite surfactant comprises trace element small peptide chelate, 2,2-dibromo-3-nitrilopropionamide and lumbrukinase in a mass ratio of 1-1.5: 1: 1-1.5. The method for regulating and controlling an aquatic water environment is to add the surfactant and ammonia water or trichloroisocyanuric acid into an aquaculture contaminated water body. The surfactant can promote rise of dissolved oxygen in the aquaculture industry, has a good bactericidal effect and no toxicity, improves aquaculture effects, increases nutrients in an aquatic water body, enhances immunity of an organism and improves the survival rate of aquaculture. Research shows that a growth rate is increased by 3 to 6% and the survival rate of aquaculture is increased by 8 to 10%. The method and the composite surfactant have great significance to improvement of an ecological environment and establishment of resource regeneration technology.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a composite functional surfactant for regulating the environment of aquaculture water and a method for using the same. Background technique [0002] At present, the aquaculture industry in our country has been very developed, but the development of aquaculture industry has also brought some problems, such as the pollution of the aquaculture water body, which has caused a great impact on the nearby waters, and the treatment of the aquaculture water body is imminent. At present, the following problems exist in the aquaculture water body and the existing treatment methods: 1) The algae multiply too much, and the pH changes greatly. From the observation of the water color, the water color is relatively thick. The treatment method is: change part of the water if there is groundwater source, and at the same time release beneficial microbial preparations (such as "living water" or "p...
