Nine, invention description: [Technical field to which the invention belongs] Law, ί: Party attachment, and other aspects can also avoid pollution of the ocean; It is resistant to living things. [Prior Art] Current and future worlds of net ants are not only excessively used for fresh water resources, but also at low sea level. The long coastline of Taiwan is conducive to the reduction of marine aquaculture. The design of the sinking has been quite mature, but the effectiveness of the fixed moisture-resistant rope also shortens the service life of the net. In order to prevent contamination = install copper wire in the netted knot or periodically drain the decontaminant, but the complex: I have doubts about the dyed sea area. In recent years, due to environmental protection; use of antifouling coatings containing heavy metals. Past breeders have not been allowed to use the coating of foreign organisms containing tributyltin (ΤΒΤ). However, as the environmental awareness of the world is high, the use of highly toxic toxic substances is restricted. International Ruihai: In 2003, banned cockroaches Antifouling coatings, surface paintings from 2 to 8 years, must not contain antimony ingredients. Therefore, at this stage, the aquaculture industry has to use the water column cleaning method to remove the marine attachments on the fixed net, but this method must not only A lot of manpower and machine costs are spent, and high-frequency cleaning can also cause operational problems for fishermen. θ '·, ,,

Gentile et al. pointed out from the power plant site investigation that when the total residual gas concentration > ι 〇 our case number 05P0445 5 1283162 士 L a supplement without ppm will cause plant plankton and 75% of animal plankton death. In addition, other studies have also found that continuous gas emissions can cause significant response to plant plankton. Sc〇lt et al. found that chlorinated seawater is toxic to earthworms in insomnia. The experimental results of Chen Yaohu et al. suggest that the safe concentration of residual gas in the discharge water of power plants should be controlled at O.Olppm~〇·〇28 ppm, so as not to cause impact on natural life. "The Mitsubishi Heavy Industries Palace develops seawater electrolysis method. The conductive coating containing copper compound is used as the anode to electrolyze seawater to produce hypochlorite ion antifouling. Although it does not affect the marine ecological environment, the use of metallic materials as anodes is likely to cause dissociation. In seawater, it cannot be used for a long time, and the copper compound in the coating will decrease with time. The effect of jp on the best use of platinum is also costly. Therefore, the improvement of electrolysis resistance remains to be solved. The most common and economical method of causing marine life on the surface of marine structures is the use of chlorine or electrolyzed seawater to produce hypochlorous acid, which prevents the attachment of marine organisms. Currently, this method has been widely used. It is used in the cooling system of the power plant.
