Problems solved by technology

At present, the underwater organisms and microorganisms (seabed, river bottom, lake bottom, etc.) are directly added with various chemical agents or disinfected by physical means at home and abroad. This kind of feeding and manual salvage costs a lot, and it is difficult to disinfect continuously underwater organisms; moreover, the disinfecting methods and disinfecting agents of the prior art will pose a considerable threat of toxicity to people and other organisms in the water (such as: fish, shrimp, and nearby aquaculture organisms), which are not friendly to the environment. Affect the surrounding water quality environment and the growth of cultured species and other species in the water body; in addition, it is difficult for the pesticides in the prior art to disinfect harmful organisms on the bottom of the water in a large area, and they are often loosely released before reaching the bottom of the water, which not only causes The waste of disinfectants can also cause damage to other organisms; finally, the disinfectants in the prior art have poor persistence and cannot achieve the effect of continuously killing underwater organisms in corresponding areas

Embodiment 1

[0025] The preparation of embodiment one complex

[0026] The attapulgite clay mined in Xuyi, Jiangsu was used to prepare the compound of this embodiment, and the specific steps were as follows:

[0027] Step 1, the attapulgite clay is refined for purity, dried until the water content is lower than 60%, and the carrier is obtained;

[0028] In step 2, the non-oxidized polyquaternary ammonium salt anti-shell agent is mixed with the carrier obtained in step 1; the mixing ratio of stirring and exchange is 1-10:90-99, and the mixing condition is 70-90°C for 1-5 Hour;

[0029] Step 3, coating with a water-soluble film to obtain a compound for disinfecting underwater harmful organisms.

Embodiment 2

[0030] Example 2 Forebay of Ningde Nuclear Power Cooling Water Circulation System

[0031] Ningde Nuclear Power Plant is located in Fujian Province. There are a large number of shellfish, sea sweet potatoes and algae in the sea area. The existence of these species often causes sea sweet potatoes to flood into the arresting net when the tide comes, blocking the mesh, seriously affecting the insufficient water circulation, and causing shutdowns. reactor, which seriously threatens nuclear safety, and at the same time has greater economic losses (each shutdown is 1 hour, economic loss is 10,000,000 yuan per hour, and each nuclear power plant has at least 3 units.

[0032] The applicant used this water area to carry out a comparative experiment. Before using the compound of the present invention, the traditional sterilant was used to put the relevant water area and salvage regularly every month, and the impact of aquatic organisms on the power station in the past year was counted. ...

Abstract

The invention discloses a compound for killing harmful underwater organisms. The compound comprises a carrier supporting a killing agent which is non-oxidized poly(quaternary ammonium) or quaternary ammonium killing agents, and the carrier is selected from attapulgite clay or quartz sand with the specific gravity being 2.05-2.75. A brand-new solution to killing underwater organisms is put forward, the requirements of quick throwing and non-disintegration in water can be met, and the compound also has the advantages of capability of covering wide water areas, low pollution and long killing lasting time.

Description

technical field [0001] The invention relates to a compound for disinfecting harmful organisms or microorganisms, in particular to a compound for disinfecting underwater harmful organisms and a preparation method thereof. Background technique [0002] No matter it is fresh water or sea water, underwater harmful organisms such as water hyacinth, Haitian melon and other algae and shellfish will have a huge impact on agricultural (such as lotus root planting) and industrial (such as hydropower, offshore nuclear power plants, etc.) production. At present, the underwater organisms and microorganisms (seabed, river bottom, lake bottom, etc.) are directly added with various chemical agents or disinfected by physical means at home and abroad. This kind of feeding and manual salvage costs a lot, and it is difficult to disinfect continuously underwater organisms; moreover, the disinfecting methods and disinfecting agents of the prior art will pose a considerable threat of toxicity to pe...
