Embodiment 1

[0032] refer to figure 1 , water purification device for eutrophic rivers, including rubber dams 1 and 2, a nano-catalyzed electrolyzer 3, a water pump 4 and an aeration device 5, the nano-catalyzed electrolyzer 3 can be placed on the bank or on the rubber dam 1. The rubber dam 1 and the rubber dam 2 cooperate to block the eutrophication river into an upstream part 6, a midstream part 7 and a downstream part 8. The water pump 4 connects the nano-catalyzed electrolyzer 3 and the upstream part 6 in series through the pipeline. The nano-catalyzed electrolyzer 3. The electrolyzed water then flows into the midstream part 7, and the aeration tube 51 (usually a water distributor) of the aeration device 5 is evenly distributed in the midstream part 7, and the water in the midstream part 7 is then aerated Discharge into downstream section 8. The anode of the above-mentioned nano catalytic electrolysis machine 3 adopts the titanium substrate anode whose surface is covered with a metal ...

Embodiment 2

[0038] refer to figure 2 , the method of this embodiment is the same as that of the above-mentioned embodiment 1, and the structure is also basically the same. The main difference is that this embodiment has two sets of corresponding nano-catalyzed electrolyzers 3' and water pumps 4' (of course, each nano-catalyzed electrolyzer Machine 3' can also be connected with multiple water pumps 4' at the same time), the purification rate of this embodiment is higher. In addition, in practical applications, the number of nano-catalyzed electrolyzers 3' can be determined according to the actual flow of eutrophic rivers.

Abstract

Disclosed is a water quality purification method for a eutrophicated river, comprising the follow steps: first, blocking a eutrophicated river and forming an upstream part, a midstream part, and a downstream part; then entering the water in the upstream part into an electrolysis machine for electrolysis; discharging the electrolyzed water into the midstream part, and performing aeration treatment; lastly, letting the aerated water flow into the downstream part. By using a method of an electrolysis process and an aeration process in sequence, the algae growth in the water and the anaerobic reactions in the water body are effectively inhibited, organic matters are decomposed, the total nitrogen, total phosphorus, and color of the water are lowered, odors are eliminated, river water quality is improved within a relatively short period, and the water ecological system is restored. Also disclosed is a river water quality purification device, comprising a rubber dam, a pump, an electrolysis machine, and an aeration device. The device can be directly installed in the river and can directly purify river water without the need to guide the river into a pre-set structure for treatment. The present invention makes almost no change to the environment, and therefore has a relatively small impact on the natural environment.

Description

technical field [0001] The invention relates to a river water treatment technology, in particular to a purification method and device capable of effectively treating eutrophic rivers, and belongs to the field of environmental protection. Background technique [0002] The river system is one of the important ecosystems in nature, which has multiple functions such as water delivery, flood discharge, landscape, shipping and breeding. With my country's rapid industrialization, urbanization and the intensification of non-point source pollution, river pollution has become a serious environmental problem. Excessive pollutants such as oxygen-consuming organic matter, nitrogen, phosphorus, and toxic substances enter the river water body, destroying the function of the river and the balance of water ecology, exacerbating the shortage of water resources, and threatening the health of residents near the water area. According to the recently released "2010 China Environmental Status Bul...
