Embodiment Construction

[0013] The application of vitamin K of the present invention as the biological control of red worm pollution in the prevention and treatment of water supply system is to put vitamin K (active ingredient β-menaquinone) produced by Dalian Dajiang Industry and Trade Co., Ltd. into it according to the concentration of 1.0mg / L In the water supply system, it can effectively inactivate bloodworms or control bloodworm pollution, so as to prevent the water supply system from being polluted by bloodworms.

[0014] The 24-hour control effect of red worms is shown in Table 1. The concentrations (mg / L) of the five chemicals of vitamin K in the water supply are directly proportional to the death rate of red worms, and the average death rate of red worms increases with the increase of the concentration of the chemicals in the water supply. The 24-hour half-lethal concentration (LC50) calculated by the linear interpolation method was 0.77 mg / L.

Abstract

The present invention relates to the application of vitamin K, and is especially method of utilizing vitamin K in killing and eliminating blood warms in water supply system. The marketable industrial level vitamin K has active component beta-methyl naphthaquinone, and is thrown into water in the concentration of 1.0 mg / L to eliminate blood warm pollution. The said method is safe, harmless on human body, mammal and water environment, low cost and other advantages. The present invention is used as the biological control technology widely used in preventing and treating blood warm pollution of water supply system.

Description

technical field [0001] The application of vitamin K in the prevention and control of bloodworm pollution in the water supply system involves the new application of vitamin K and its application method. It belongs to the field of application of biological control technology in water supply system. technical background [0002] In recent years, there have been more and more reports on drinking water pollution. In many areas in southern my country, such as Guangdong, Sichuan, Jiangsu, Zhejiang, Shanghai and other places, red microscopic organisms have been found in secondary water supply tanks and pipe networks— — Chironomus larvae (commonly known as "red worms") are frightened. Because the red worms in the water tank not only directly affect the sensory indicators of the tap water, but also bacteria and viruses may enter the red worms and spread the disease. With the deterioration of water quality, especially the eutrophication of water bodies, red wor...
