Problems solved by technology

[0003] The present invention solves the problems in the prior art that there is no separation of clear water and sewage when treating black and odorous water bodies in cities, the treatment time is long and the problem is low, and it provides a treatment method that can effectively purify black and odorous water bodies in cities. Its application Efficiently purify the black and smelly water in urban rivers, effectively solve the problem of black and smelly water in urban rivers, increase the amount of dissolved oxygen in the purified water, and greatly reduce the organic pollution of the purified water

Embodiment

[0021] The treatment method that can effectively purify the black and odorous water in the city, the following steps are performed in sequence: detect the location of the black and odorous water in the city and classify it according to the pollution situation; install a sewage interceptor in the polluted river to intercept the black and odorous water in the river; Install an aeration device in the downstream channel of the sewage interception device; install artificial aquatic plants in the downstream channel of the aeration device; install a sewage delivery pump in the upstream channel of the sewage interception device; install a dialysis purification device between the sewage interception device and the sewage delivery pump, The black and odorous water is transported to the dialysis purification device through the sewage pump and then discharged into the sewage interception device. Wherein: the dialysis purification device in the step F includes a bubble releaser, through whi...

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...
