Problems solved by technology

[0010] At present, the methods for removing peculiar smell in the aquaculture industry have the disadvantages of high operating cost, complicated operation, or environmental pollution by drugs, and cannot eradicate the content of 2-methylisoborneol and xylalinol in the water body, so they are widely used in popularization and application. constraints

Embodiment 1

[0021] Embodiment 1: taking shad as an example, the method for removing the smell of soil in the circulating water system of the holding pond is: the aquatic product living body is put into the holding pond temporarily, and (40~200 square meters) is cleaned in the holding pond temporarily, Add well water or clear water, aerate, adjust the water temperature (temperature difference < 2°C), put the shad commercial fish into the holding pond, and ensure that the dissolved oxygen is above 5mg / L.

[0022] The aquaculture sewage enters the solid-liquid separator. The solid-liquid separator produced by Hydrotech is selected. The filter mesh has a pore size of less than 60 microns to remove solid waste in the water.

[0023] Clean water is purified in the biochemical water treatment pool to remove water-soluble waste such as ammonia nitrogen.

[0024] In the ozone peroxidation tank, the purified water treated by biochemical water is oxidized: the ozone machine produced by PacificOzoneT...

Abstract

The invention discloses a method for improving the quality of aquaculture products, and relates to the technical field of aquaculture. The method particularly includes the steps of placing aquatic product living bodies in a circulating water aquaculture system for aquaculture; filtering water discharged form an aquaculture pond with a solid-liquid separator, wherein the hole diameter of a filtering net ranges from 20 micrometers to 100 micrometers; enabling filtered clean water to enter a microorganism biochemical water processing system; conducting peroxidation processing on clean water after biochemical water processing in a hydrogen peroxide-ozone oxidation pond; conducting ultraviolet sterilization processing in an ultraviolet sterilizer on clean water after the hydrogen peroxide-ozone oxidation processing , enabling the clean water to return to the aquaculture pond, and achieving cyclic utilization of aquaculture water. The method is easy and convenient to operate, 2-methylisoborneol, dimethyl naphthalene alcohol and generated microorganism sources of the 2-methylisoborneol and the dimethyl naphthalene alcohol which cause peculiar smells such as the earthy smell are directly or indirectly eliminated under the synergistic effect of ozone, the ultraviolet technology and the hydrogen peroxide sterilization technology, residues of hazardous substances such as a plurality of kinds of heavy metal and pesticides are remarkably reduced, ad the quality and the value of the products are improved.

Description

Technical field: [0001] The invention belongs to the technical field of aquaculture products, and in particular relates to a method for improving the quality of aquaculture products. Background technique: [0002] In the past ten years, due to the aggravation of eutrophication in water bodies, in the aquaculture industry, peculiar smells such as earthy and musty smells of aquatic products have always been one of the major problems that plague the development of the industry. When the product is sold, due to quality problems such as the peculiar smell in the fish meat, the opportunity to go on the market is often missed, or even unable to go on the market, resulting in a sharp drop in price. In order to meet the requirements of product quality, the breeding owners usually postpone the sale for several weeks and carry out clean water treatment before sale, which not only increases the production cost, but also brings many risks, and in serious cases, it will cause huge economi...
