Problems solved by technology

[0005] However, the biological flora in the biofilm method is still the activated sludge from the sewage plant. All kinds of organisms are mixed together, and the active organisms are difficult to control artificially, so the flexibility in operation is poor; in addition, due to the ratio of carrier materials The surface area is small, so the volume load of the equipment is limited, the biological concentration is low, and the treatment efficiency is poor; third, the water purified by the biofilm method often contains a large shedding biofilm, which reduces the clarity of the effluent

Embodiment 1

[0049] Such as figure 2 As shown, a sewage treatment system includes a plurality of sewage treatment tanks connected in series, each sewage treatment tank is provided with a water inlet 1, a water outlet 2, and a carrier 6 for providing a growth environment for microorganisms in sewage biological treatment;

[0050] At the same time, an upper punching plate 3 for carrying and fixing the carrier, a lower punching plate 4, the upper punching plate 3 and the lower punching plate 4 are arranged between the water inlet 1 and the water outlet 2 of the sewage treatment tank; The water inlet 1 of the treatment tank is set at the bottom 8 or the top 9 of the sewage treatment tank according to the water inlet, and the water outlet 2 is set at the top 9 or the bottom of the sewage treatment tank according to the setting of the water inlet 1 8 places; the vertical distance between the upper perforated plate 3 and the top 9 of the sewage treatment tank is 0.2-1.0m, and the vertical distan...

Abstract

The invention discloses a sewage treatment system which comprises a plurality of serially connected sewage treatment tanks. Each sewage treatment tank comprises a water inlet, a water outlet and a carrier, and the carriers are used for providing growing environments of microorganisms in biological sewage treatment. The system specifically treats pollutant by a multistage grading treatment method and is good in treatment effect, low in expense and investment, small in occupied area, high in biological concentration, high in impact resistance, less in producing sludge, free from backflow and odor, and different sources of microorganisms exist in the carries by the aid of a stereoscopic structure.

Description

technical field [0001] The invention relates to the technical field of sewage treatment. More specifically, it relates to a sewage treatment system. Background technique [0002] The existing technologies for sewage biological treatment are mainly two categories: activated sludge method and biofilm method. [0003] The biological flora used in the activated sludge method is domesticated through the slow cultivation of activated sludge in sewage treatment plants, and the biological flora domesticated from the activated sludge of different sewage treatment plants are mixed in the biochemical pool, and the biological flora It is dispersed in the form of granular sludge. The main problem of this activated sludge method is that various biological flora are mixed together, and there are survival relationships such as predation, competition, and mutual interference between different organisms, and problems such as sludge bulking are prone to occur during operation, so the treatme...
