A floating sewage treatment device for purifying black and odorous water

Abstract

The invention discloses a floating sewage treatment device for purifying black and odorous water. The floating sewage treatment device comprises a ship hull, ecological treatment bed combiners, a secondary sedimentation tank and ecological islets. The ecological treatment bed combiners comprise first-layer ecological beds, second-layer ecological beds, third-layer ecological beds, fourth-layer ecological beds, fifth-layer ecological beds, sixth-layer ecological beds, seventh-layer ecological beds and eighth-layer ecological beds which are sequentially stacked from top to bottom, each ecological bed is sequentially provided with a water inlet chamber, a filler chamber and a water outlet chamber, and electronic pacemakers are arranged on the side walls of the filler chambers; water outlets are formed in the water outlet chambers, the water outlet chambers of the upper-layer ecological beds are communicated with the water inlet chambers of the corresponding lower-layer ecological beds via the corresponding water outlets, the filler chambers of the first-layer ecological beds are filled with PVC (polyvinyl chloride) fillers, the filler chambers of the second-layer ecological beds, the fourth-layer ecological beds and the eighth-layer ecological beds are filled with cobble with different particle sizes, the filler chambers of the third-layer ecological beds are filled with ceramsite materials, the filler chambers of the fifth-layer ecological beds are filled with gravel, the filler chambers of the sixth-layer ecological beds are filled with mixtures of gravel and activated carbon, and the filler chambers of the seventh-layer ecological beds are filled with ceramsite materials. The floating sewage treatment device has the advantages that the floating sewage treatment device is high in efficiency and low in energy consumption and cost, and the black and odorous water can be uninterruptedly stably treated by the floating sewage treatment device for a long term.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a floating sewage treatment device for purifying black and odorous water. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, people's requirements for environmental quality, especially water environment quality, are getting higher and higher. Urban black and smelly water is a water environment problem that people strongly report, which not only damages the urban living environment, but also seriously affects the image of the city. [0003] At present, the domestic treatment of black and smelly rivers is based on the misunderstanding of "treating the head and feet for headaches and treating the feet for pain", lacking systematic treatment. As a result, many black and odorous water bodies rebounded after being treated for a period of time. The water affairs department has adopted engineering thinki...

Caused many black and odorous water bodies to rebound after a period of treatment

The water affairs department has adopted engineering thinking for a long time, coupled with various factors such as the confluence of rain and sewage, non-point source pollution, etc., even if a large amount of money is invested, it is still difficult to achieve the treatment effect

Encouraging low-price bidding and formulating bidding requirements is too simple, all of which have caused the problem of black and odorous water bodies to be delayed for a long time
