摘　　要：水被电解后,电解装置阴极产氢、阳极产氧。本试验采用自来水进行预试验,从而确定水中DO浓度可通过电解作用而增加。向水中加入豆粉、枯枝落叶以模拟富营养化水体。结果表明:放入电解装置的试验组中,DO浓度仍可大幅提升,且水不会散发臭味;若将电解装置放在水底,则可达到深层复氧的目的。水电解后产生的气泡可带走水中的CO2,使水体pH保持中性。After the water is electrolyzed,cathode produces hydrogen and anode produces oxygen.This test conducted a preliminary experiment with tap water to determine that dissolved oxygen(DO)in water could be increased by electrolysis device.In order to simulate eutrophication water,soybean flour and litter were added into the water.DO concentration of the test group added with electrolysis device was still greatly improved,and the water did not become odorous.If the electrolysis device was placed on the bottom of the water,the purpose of deep reoxygenation could be achieved.Since bubbles were generated after electrolysis of water,CO2 in the water could be taken away,and pH value of the water could be kept neutral.
