Problems solved by technology

[0003] In the existing technology, the content of ammonia nitrogen is high, and most of them adopt the method of changing water. However, due to the limitation of water resources in some places, it is impossible to ensure enough clean water to change water.
At the same time, the method of changing water also increases the waste of water resources in aquaculture.
A large amount of algae grows, and most of them are salvaged manually, which increases labor costs
Most of the fungicides are sprinkled into the water for the growth of bacteria. Some fungicides remain in the body of aquatic products and are eventually absorbed when humans eat aquatic products. Long-term consumption of such aquatic products is very harmful to the human body.
In addition, in order to prevent aquatic products from getting sick, people often add antibiotics to the feed, because long-term use leads to a large amount of antibiotic residues in aquatic products
After humans eat such aquatic products, the antibiotics in the human body will increase, causing some viruses in the body to develop drug resistance, making the disease more difficult to treat

Abstract

The invention relates to the technical field of water quality treatment and methods, in particular to water quality treatment equipment for aquaculture, which sequentially comprises a sand filter tank, a buffer reaction tank, a sterilization tank, an adsorption tank and a sand filter backwashing tank, wherein the buffer reaction tank is further connected with a sodium hypochlorite generator, the adsorption tank is further connected with a sodium thiosulfate liquid storage tank, and the sand filter backwashing tank is also connected with a lime water storage tank. The water quality treatment method comprises the following steps of carrying out sand filter on a pond, mixing with a sodium hypochlorite solution, conveying to a buffer reaction tank for reaction, conveying to a sterilization tank, mixing with a sodium thiosulfate solution, conveying to an adsorption tank for reaction, mixing with lime water to adjust the pH value, and finally respectively conveying to the pond and a sand filter tank through a sixth pipeline and a seventh pipeline. The method solves the problems of high ammonia nitrogen content, excessive algae and bacteria breeding in the prior art, and has the advantages of high algae removal rate, high ammonia nitrogen removal rate, high working efficiency, low cost and high bacteria removal rate.

Description

technical field [0001] The invention relates to the technical field of water quality treatment and methods, in particular to water quality treatment equipment and a water quality treatment method for aquaculture. Background technique [0002] In order to increase the unit output in current aquaculture, most of them use high-density farming. However, there are also some problems. The higher the breeding density, the more waste of excrement and feed of aquatic products, resulting in eutrophication of the water body, high ammonia nitrogen content, massive growth of algae, and bacterial growth. High ammonia nitrogen content to a certain extent will directly lead to the poisoning and death of aquatic products, which is also the reason for the massive growth of algae. A large number of algae growth will cause the following hazards: 1. Algae absorb a large amount of dissolved oxygen in the water, resulting in the reduction of dissolved oxygen in the water, resulting in the death o...
