Embodiment 1

[0018] Embodiment one: to the processing of domestic water (belonging to still waters), as figure 2 shown. The processing chamber is a cylindrical shape made of insulating material, with a height of 0.5 meters. The diameter of the top 5 and the bottom 8 is 0.5 meters. Both the top 5 and the bottom 8 are made of a sealed plate. Part 6 is sealed and connected with the whole plate, so that the whole processing chamber is kept sealed. A water inlet is opened at 0.4 meters away from the bottom 8 on the side part 6 of the treatment chamber, and a drainage hole is opened at 0.05 meters away from the bottom 8 . The high-voltage discharge electrode adopts parallel plate electrodes, the top electrode is installed on the inner side of the top 5 of the processing chamber, and the bottom electrode is installed on the inner side of the bottom 8 of the processing chamber. The water to be treated is injected into the treatment chamber through the water inlet hole. The water level 7 in the ...

Embodiment 2

[0019] Embodiment two: to the processing of open waters, as image 3 shown. The processing chamber is a rectangular parallelepiped made of insulating material, 0.5 meters high, 0.3 meters wide, and 0.4 meters long. The top 5 and bottom 8 are made into transparent grids. 6 Use four support rods to connect at intervals to maintain the transparency of the top, bottom and side of the processing chamber. The high-voltage discharge electrode adopts parallel plate electrodes, the top electrode is installed on the inner side of the top 5 of the processing chamber, and the bottom electrode is installed on the inner side of the bottom 8 of the processing chamber. Use a ship to hoist the treatment bin into a certain water area to be treated. The depth of the treatment bin is 0.2-0.35 meters. Apply a high-power pulse with an intensity of 15KV, a bipolar rectangular wave, and a frequency of 60KHZ. The treatment duration is longer than After 1 second, the ship continues to move the treatm...

Abstract

The high power pulse blood fluke cercaria killing method is that after the treating compartment with high voltage discharge electrodes is set inside water area to be treated, high power pulse voltage is applied across the electrodes so as to generate mechanical effect, electromagnetic effect, optical effect, thermal effect and chemical effect to kill blood fluke cercaria in water continuously. The present invention has the advantages of high killing efficiency, no toxicity, no harm, no pollution, and no drug resistance of blood fluke cercaria and others, may be used in killing blood fluke cercaria in great water area and treating water for production and life.

Description

technical field [0001] The invention relates to a method for killing harmful animals, in particular to a high-power pulse killing method for cercariae of schistosomiasis. Background technique [0002] Cercariae are an important stage of schistosomiasis infecting the human body, and killing cercariae is the key to the prevention and treatment of schistosomiasis. In the traditional control of schistosomiasis, the killing methods for cercariae mainly include drug method, storage method and heating method. The drug method is to kill the cercariae by sprinkling tea seed cakes, bleaching powder or quicklime; the storage method is to store the plague water containing the cercariae for a few days, and use the living characteristics of the cercariae to make the cercariae die naturally; The method of killing cercariae by heating water to about 60°C. The problem with the above-mentioned killing method is that the drug-killed cercariae cause the cercariae to produce drug resistance, a...
