Problems solved by technology

The treatment work must be carried out when the water is cut off across the line, which not only requires a lot of manpower and material resources, but also causes a certain degree of damage to the wall of the water delivery pipe during the scraping process, which affects the service life of the water delivery project
Moreover, the pipe wall after scraping is rougher than before scraping, which is more conducive to the adhesion of fouling organisms, which will bring greater hidden dangers
[0007] 2. Coating protection method: apply protective paint on the surface of engineering objects to improve the smoothness of the surface of the object and reduce the adhesion of fouling organisms. Some paints contain insecticides that can kill fouling organisms, but From the perspective of application, the protective effect is not obvious
[0008] 3. Chemical killing method: At present, a variety of chemical killing agents have been studied for the killing of fouling organisms, such as chlorine gas and sodium hypochlorite as the killing agents of marsh clams, but there are very few reports on practical application
It is more prudent to use chemical methods in drinking water delivery projects to prevent fouling organisms from invading and reduce biofouling. The impact of chemicals on water quality and the environment cannot be ignored, and the cost of huge chemical doses is very high.
[0009] So far, there is no safe, reliable, effective, selective device for killing harmful microorganisms in the water

Embodiment Construction

[0043] The specific implementation will be described in detail below in conjunction with the accompanying drawings.

[0044] A device for killing harmful microorganisms in water, comprising an overflow channel and an orifice plate installed therein, the overflow channel can be an overflow pipe (such as a water pipe) or an overflow sink (such as a ditch), and of course it can be Other forms of water passage, such as water flow passages in other devices, such as cooling water pipes. The flow passage includes a water inlet end and a water outlet end, and the water inlet end can be connected with a natural water source or a water inlet pool containing a natural water body or a water treatment device; the water outlet end can be connected with a water device or a water delivery project or a follow-up water Processing device connection. There is a power system to promote the flow of water at the water inlet and / or water outlet, for example, a device for providing or controlling wat...

Abstract

The present invention provides a killing apparatus for harmful microbody organisms in water. The killing apparatus comprises an overflowing channel and hole plates arranged inside the overflowing channel. The hole plate crosses the overflowing channel along the overflowing cross-section direction, and forms a fixed connection with the inner wall of the overflowing channel, wherein no gap is remained between the hole plate and the inner wall of the overflowing channel. According to the present invention, with the pushing effect of the power system for pushing the flow of the water, the water flow passes through the hole plates with different specifications so as to generate different pulse waves, such that the harmful microbody organisms in the water can be effectively and selectively killed, wherein the body lengths of the harmful microbody organisms are in a certain body length range, therefore, the use requirements of the water source are met, the organisms living in the water are not damaged or damaged less so as to contribute to the use of the water source, wherein the body lengths of the organisms living in the water are not the same as the body lengths of the killed subjects. The present invention further relates to a killing method for the harmful microbody organisms in the water, and a water conveying engineering system applied by the killing apparatus and the killing method.

Description

technical field [0001] The invention relates to a device for killing harmful micro organisms in water, in particular to a device for killing fouling organism larvae in a water body, a method for killing them and a water delivery engineering system. Background technique [0002] All kinds of water sources in nature (including fresh water and salt water) generally contain a certain amount of microscopic organisms that can be harmful to humans. When humans use such water sources, or in order to control the growth of harmful micro organisms, they need to kill harmful micro organisms in water. The harmful micro organisms in the water refer to tiny aquatic organisms with a body length of 0.01-5mm, mainly small and medium-sized plankton. An organism that poses a hazard, or is a host organism for a pest. For example, larvae of fouling organisms, etc. [0003] The operation of many water delivery projects is plagued by fouling organisms to varying degrees. Fouling organisms attach...
