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] Example 1 Preparation of complex

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

[0027] Step 1. The attapulgite clay is refined and dried until the moisture content is lower than 60% to obtain the carrier;

[0028] Step 2. Mix the non-oxidized polyquaternary ammonium salt shellfish with the carrier obtained in Step 1 by stirring and exchange mixing; the ratio of stirring and exchange mixing is 1-10:90-99, and the mixing condition is 70-90°C, mixing 1-5 hour;

[0029] Step 3: Coating with a water-soluble film to obtain a compound used to kill underwater pests.

Embodiment 2

[0030] Example 2 Ningde Nuclear Power Cooling Water Circulation System Front Pool

[0031] Ningde Nuclear Power is located in Fujian Province. There are a large number of shellfish, Haitian melons and algae in the sea area. The existence of these species often causes Haitian melons to flow into the barrier net when the tide comes, block the mesh, seriously affect the insufficient water cycle, and cause the shutdown. The reactor seriously threatens nuclear safety, and at the same time has greater economic losses (each shutdown for 1 hour, the economic loss per hour is 10 million yuan, and each nuclear power plant has at least 3 units.

[0032] The applicant used this water area to conduct a comparative experiment. Before using the compound of the present invention, he used a traditional killer to put into the relevant water area and salvaged it at regular intervals every month to calculate the impact of underwater organisms on the power station in the past year.

[0033] Then use the ...

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 killing harmful organisms or microorganisms, in particular to a compound for killing harmful organisms at the bottom and a preparation method thereof. Background technique [0002] Whether 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 the production of agriculture (such as lotus root planting) and industry (such as hydropower, offshore nuclear power plants, etc.). At present, the underwater organisms and microorganisms (seabed, river bottom, lake bottom, etc.) at home and abroad are all directly added with various chemical agents or killed by physical means. The cost of such injection and manual salvage is high, and it is difficult to continuously kill Underwater organisms; moreover, the disinfection methods and disinfectants of the prior art will pose a considerable toxic threat to the personnel and other org...
