Embodiment 1
[0031] Example 1: Micro-electrolysis treatment of Longfeng Wetland
[0032] 1.1 Wetland background
[0033] The wetland has been polluted by petrochemical sewage, agricultural sewage, and urban domestic sewage for a long time. At present, the overall water quality is deteriorating. The water body is black and green, and there are a lot of duckweed on the water surface. The eutrophication has become very serious; most of the waters have lost their self-purification function. , Local areas have begun to have a peculiar smell. If it is not treated, not only the wetland itself will fall, but it will also have a serious impact on the surrounding ecological environment.
[0034] The average water depth of this wetland is about 1.2 meters, and the water depth is about 0.5 meters where there are reeds, and the water surface is separated by pieces of reeds. Samples were taken near the shore, and the COD was 112mg / L and the ammonia nitrogen was 36.3mg / L. Before being treated by the m...

[0041] Embodiment 2: the micro-electrolysis treatment of fishpond
[0042] figure 1 Shown is a kind of fixing device and aeration device adopted in the micro-electrolysis treatment method of the present invention, wherein, two pairs of intersecting bamboo poles or wooden stakes are inserted into the bottom of the water, and another bamboo pole or wooden stakes are straddled at the intersection, the Bamboo poles or wooden stakes are placed in the water body, and a container (such as a nylon filter cloth bag) with microelectrodes is suspended below it, and an air disc (such as a nylon filter bag) as an aeration device is arranged at the bottom or around the container with microelectrodes ( A number of air holes are set above). Of course, those skilled in the art should know that the intersecting bamboo poles or wooden stakes inserted into the bottom of the water are not limited to two pairs, and the bamboo poles or wooden stakes across the intersection are not limited to one. ...
Embodiment 21
[0045] The area of a fish pond discharged into pig manure is about 1 mu, and the average water depth is 1.5 meters. Under the action of an ordinary aerator, the COD of the water is 380mg / l, and the ammonia nitrogen is 8mg / l , the nitrite is 0.06mg / l , the pH value is 7.1 , the dissolved oxygen is 2.8mg / l . Put an iron basket with a volume of 0.6m*0.6m*0.8m (length*width*height) in the fish pond, and there are 20 iron baskets wrapped in 120-mesh nylon filter bags as disclosed in Chinese patent 200910038783.1 Iron-carbon microelectrodes for wastewater microelectrolysis treatment. The iron basket is fixed in the water with wooden stakes, and the bottom of the iron cabinet is equipped with an aeration tube with holes. is 114mg / l, ammonia nitrogen is 3mg / l , the nitrite is 0.03mg / l , the pH value is 7.32 , the dissolved oxygen is 5.21mg / l . After 48hr continuous aeration treatment, the COD of the water is reduced to 36mg / l , ammonia nitrogen is 2mg / l , the nitr...
