Problems solved by technology

[0002] With the advancement of science and technology and the development of social economy, the aquaculture industry, especially the mariculture industry, has been greatly developed in recent years. This unfavorable factor, in turn, restricts the development of the aquaculture industry, making it face a great threat, especially the breeding of aquatic products
At present, the treatment of seawater is mostly to remove impurities and purify first, and then use drugs to sterilize the seawater. In this way, harmful substances will remain in the sterilization process, causing the aquatic products produced to contain harmful substances, which affects the quality of aquatic products.

Embodiment Construction

[0007] The present invention will be further described below in conjunction with accompanying drawing:

[0008] First, the seawater is pumped into the sand filter tank for sand filtration to remove large particles of impurities in the seawater; then the seawater is first filled with air into the seawater by air flotation in the treatment tank, and then a part of the surface water is discharged to remove the seawater Micro organic matter and impurities in the water, reduce the ozone consumption in the post-sterilization process and improve the bactericidal effect of ozone, and then use the circulation reflux method to mix ozone in the reflux process, so that the ozone concentration in seawater is between 0.1-0.3PPm , and then let the seawater stand still for 1-2 hours; filter the seawater after standing still with activated carbon, and then let the seawater stand still or blow air for 24-72 hours, and you can get the treated shrimp seedling cultivation water.

Abstract

The invention relates to a water treatment method for rearing shrimp seedling which comprises, conducting sand filtering to the cultivated shrimp seeds with sea water, removing the microtubule organic matter and foreign substance in the seawater through air-floating method, then performing short time sterilization and hazardous substance decomposition by means of circulating reflux mixing, stewing and filtering with activated charcoal, and stewing the filtered sea water.

Description

technical field [0001] The invention relates to a treatment method of water for cultivation, in particular to a treatment method of water for cultivation of shrimp seedlings. Background technique [0002] With the advancement of science and technology and the development of social economy, the aquaculture industry, especially the mariculture industry, has been greatly developed in recent years. These unfavorable factors have restricted the development of the aquaculture industry in turn, making it face a great threat, especially the breeding of aquatic products. At present, the treatment of seawater is mostly to remove impurities and purify first, and then use drugs to sterilize the seawater. In this way, harmful substances will remain in the sterilization process, causing the aquatic products produced to contain harmful substances, which affects the quality of aquatic products. .
