Treatment method capable of effectively purifying black and odorous water in city

Abstract

The invention discloses a treatment method capable of effectively purifying black and odorous water in a city. The method successively comprises the following steps: detecting positions of black and odorous water in the city and classifying according to pollution conditions; mounting a pollutant intercepting device in a polluted river channel and intercepting the black and odorous water in the river channel; arranging an oxygenation device in a downstream river channel of the pollutant intercepting device; mounting artificial aquatic plants in a downstream river channel of the oxygenation device; and mounting a sewage conveying pump in an upstream river channel of the pollutant intercepting device. Through the treatment method, the problems of long treatment time and low efficiency causedby not separating clear water from the sewage when the black and odorous water in the city is treated in the prior art are solved; the treatment method capable of effectively purifying the black and odorous water in the city is used for efficiently purifying the black and odorous water in the river channel of the city; the problem that the water in the river channel of the city is black and odorous can be effectively solved; the content of oxygen dissolved in the purified water is increased; meanwhile, the organic matter pollution in the purified water can be greatly reduced.

Description

technical field

[0001] The invention relates to a water body treatment method, in particular to a treatment method capable of effectively purifying black and odorous water bodies in cities. Background technique

[0002] Urban rivers are relatively closed, and there are many residents along the coast. After a large amount of domestic sewage flows into the river, the water body is black and smelly due to eutrophication and bacterial reproduction. At present, the treatment technologies for black and odorous water bodies include dredging and dredging, in-situ oxygenation, and biological purification technologies. The disadvantages of the above treatment technologies are that they do not effectively isolate the polluted water bodies of black and odorous water bodies, and cannot effectively separate clean water from sewage. The treatment period is long, and black and odorous phenomena will occur repeatedly. In view of this, it is necessary to improve the purification treatment of...
