Problems solved by technology

Its pollution will lead to: the reduction of dissolved oxygen in the water body, excessive ammonia nitrogen, nitrite nitrogen, and hydrogen sulfide, excessive COD, total nitrogen, total phosphorus, and ammonia nitrogen in the water body, resulting in eutrophication of the water body and deterioration of water quality, etc.; pollutants Depositing the bottom of the pond increases the oxygen consumption of the substrate and releases hydrogen sulfide and methane at the same time, which ultimately affects the survival of farmed animals

preparation example Construction

[0028] The present invention also provides a preparation method of the above-mentioned water quality improver, comprising the following steps:

[0029] Step S1: Take the thickener and water, and mix them uniformly to obtain a mixed liquid by weight parts of 0.2-1 part of the thickener and 63-86.8 parts of water. 0.2-1 part by weight of the thickener and 63-86.8 parts by weight of water are added into the batching tank and stirred evenly.

[0030] In the batching tank, use a mixer with a rotation speed of 40-60 revolutions per minute to stir for 20-40 minutes to stir the thickener and water evenly to obtain a mixed solution, and the thickener and water are stirred within the temperature range of 30°C to 50°C , preferably 40°C. The thickener is selected from one or more of sodium carboxymethylcellulose, sodium carboxyethylcellulose, xanthan gum, and polyacrylamide, and the parts by weight are preferably 0.5-1 part.

[0031] Step S2: Add 5-15 parts of sodium humate, 3-8 parts o...

Embodiment 1

[0038] The water quality improver of the present embodiment comprises the following components by weight:

[0039] Mix 10 parts of sodium humate, 0.5 parts of sodium carboxymethylcellulose, 3 parts of potassium chloride, 4 parts of sodium dodecylbenzenesulfonate, 5 parts of diethyl ethyl ethyl ethylate and 77.5 parts of water to obtain a water quality improver.

[0040] The preparation method of the water quality improver of the present embodiment is as follows: add 0.5 parts of sodium carboxymethylcellulose and 77.5 parts of water into the batching tank and stir for 30 minutes with a mixer whose rotation speed is 40 revolutions per minute until the mixed solution is obtained evenly, and then add Add 10 parts of sodium humate, 3 parts of potassium chloride, 4 parts of sodium dodecylbenzene sulfonate, and 5 parts of diethyl ethyl to the above mixture, and stir for 30 minutes at room temperature with a mixer at a speed of 50 rpm Until the water quality improver is obtained evenl...

Embodiment 2

[0042] The water quality improver of the present embodiment comprises the following components by weight:

[0043] Mix 5 parts of sodium humate, 1 part of sodium carboxyethyl cellulose, 2 parts of potassium chloride, 3 parts of potassium sulfate, 8 parts of calcium dodecylbenzenesulfonate, 3 parts of diethyl diethylethyl cellulose and 78 parts of water to obtain water quality Improver.

[0044] The preparation method of the water quality improver of this embodiment is: add 1 part of carboxyethyl cellulose sodium and 78 parts of water into the batching tank and stir for 40 minutes with a mixer with a rotation speed of 40 rpm until the mixed solution is obtained evenly, and then add Add 5 parts of sodium humate, 2 parts of potassium chloride, 3 parts of potassium sulfate, 8 parts of calcium dodecylbenzenesulfonate, and 3 parts of diethyl hexanoate into the above mixture, and use a speed of 40 rpm at room temperature The blender stirred for 35 minutes until the water quality imp...

Abstract

The invention discloses a water quality improver and a preparation method thereof. The water quality improver comprises the following components calculated in parts by weight: 5-15 parts of sodium humate, 3-8 parts of a surfactant, 3-8 parts of diethyl aminoethyl hexanoate, 2-5 parts of potassium salt, 0.2-1 part of a thickening agent and 63-86.8 parts of water. The water quality improver disclosed by the invention has the benefits that through the sodium humate, the effects of rapidly complexing heavy metal ions and harmful elements in water and reducing the contents of heavy metal ions, ammonia nitrogen, nitrite, hydrogen sulfide in the aquaculture water are realized, and the purpose of purifying a water source is achieved, so that an excellent growth environment and baits are provided for farmed animals, and the healthy growth of the farmed animals is promoted.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a water quality improver and a preparation method thereof. Background technique [0002] In recent years, with the increasing demand for aquatic products, the aquaculture industry has developed rapidly, and the scale of aquaculture has continued to expand. The subsequent self-pollution of aquaculture in various forms has also become increasingly serious, which is harmful to a certain extent. to the survival of aquaculture animals. [0003] There are two main types of pollutants produced by aquaculture itself: one is the residue of bait, fishery chemicals, pesticides and fertilizers; the other is the excrement of aquaculture organisms and dead bodies of aquaculture organisms. Its pollution will lead to: the reduction of dissolved oxygen in the water body, excessive ammonia nitrogen, nitrite nitrogen, and hydrogen sulfide, excessive COD, total nitrogen, total phosp...
