Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to an aquaculture water quality treatment process. Background Art

[0002] Aquaculture is the use of waters available for breeding (including planting) by humans, in accordance with the ecological habits of the breeding objects and the requirements for the water environment conditions, using aquaculture techniques and facilities to engage in the breeding of aquatic economic animals and plants.

[0003] With the development of aquaculture, the problem of water pollution and water body prevention and control is quite prominent. At present, the water in aquaculture ponds is treated by replacing the water in aquaculture ponds and frequently dosing medicines. However, the replacement of aquaculture pond water must be close to the water source, at the cost of discharging pollution to the water source. Frequent dosing of medicines for disinfection and sterilization can only temporarily improve the water quality. At the same time, excessive dosing will also cause water pollution, resulting in greater pollution of water sources during aquaculture. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an aquaculture water treatment process.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An aquaculture water treatment process comprises the following steps:

[0007] S1, sedimentation, putting the water from the aquaculture process into a sedimentation tank, and taking the water above after sedimentation in the sedimentation tank;

[0008] S2, aeration, adding air to the settled water to increase the dissolved oxygen content in the water and remove harmful gases in the water. In addition, the surfactant in the water is adsorbed by tiny bubbles and floats on the water surface to form foam. The water quality is purified by collecting and removing the foam.

[0009] S3, adsorption, placing a porous solid phase material in the water as an adsorbent to remove impurities in the water;

[0010] S4, flocculation, adding flocculants to the water after adsorption to make the tiny particles and colloids in the water condense into larger flocs, accelerate sedimentation, and purify the water quality;

[0011] S5, filtering, using a filter to filter the precipitate in the water after flocculation;

[0012] S6. Add photosynthetic bacteria to the filtered water to remove small molecular organic matter in the water, reduce the content of ammonia nitrogen, hydrogen sulfide, etc. in the water, reduce COD, stabilize and increase the dissolved oxygen content in the water, and promote the recycling of water substances;

[0013] S7, disinfection, ozone is introduced into the water, which can destroy and decompose the cell membrane of bacteria, diffuse rapidly into the cells, oxidatively destroy or decompose the intracellular enzymes and quickly kill the pathogens;

[0014] S8. The purified water is then transported back to the aquaculture pond.

[0015] Preferably, in step S2, an aerator is used for oxygenation, and the aerator can cause convection between the upper and lower water layers of the pond water body to increase the dissolved oxygen content in the water.

[0016] Preferably, in step S3, the porous solid phase material is one or more of activated carbon, silica gel and zeolite.

[0017] Preferably, in the step S4, the flocculant is one of alum, gypsum, aluminum salt, iron salt and organic polymer flocculant.

[0018] The present invention has the following beneficial effects:

[0019] The process for treating aquaculture water quality in the present invention makes the aquaculture water purification have the advantages of high efficiency, stable effect and easy treatment, and is very suitable for online treatment of aquaculture water, so that aquatic products can grow healthily in a good ecological environment, and can ensure a high survival rate of aquatic products, increase output value, and the aquatic products have good taste and delicious meat, and will not cause significant pollution to water sources.
