Problems solved by technology
This method requires the use of biological carriers to form biofilms. Commonly used carriers include combinations, elastic fillers, PVC suspension balls, etc. There will be a problem that the film-hanging rate is low, the film volume is small, and the tightness between the biofilm and the filler Poor affinity with organic impurities and low removal rate

Embodiment Construction
[0013] refer to figure 1 , a biological carrier sewage treatment device of the present invention, comprising a reaction tank 1, a water inlet 2, an aeration system 3, and a water outlet 4 are sequentially arranged in the reaction tank 1 from bottom to top, and in the reaction tank 1 Filled with porous granular microbial carrier 5, the porous granular microbial carrier 5 can preferably use coal particles or volcanic rock or diatomite or bentonite particles, and the porous granular microbial carrier 5 can form an "O" aerobic film on the outer surface of the particle, and the inner The layer forms an "A" anoxic film, which makes the particles become flowing "A / O" points, and the NH in the sewage 3 Continuous aerobic nitrification of -H to N 2 , blown off by aeration, reducing the nitrogen content in the sewage. Similarly, the phosphorus accumulating bacteria can be converted into orthophosphate that can be directly assimilated, reducing the phosphorus content in the sewage. At ...

Abstract
The invention discloses a bio-carrier sewage treatment device, which comprises a reaction tank, wherein a water inlet, an aeration system and a water outlet are sequentially arranged in the reaction tank from bottom to top; the reaction tank is filled with a porous particle microbial carrier. By adopting the porous particle microbial carrier, compared with a traditional carrier, an inner and outer double-layer film can be formed due to the porous characteristic and good adsorption activity, the bio-carrier sewage treatment device is more durable and practical, high in film-forming rate, high in film quantity, high in adhesive force and not easy to fall off, the compactness and the affinity between a biological film and filling are higher, the removal effect on organic matters is better, due to the bottom aeration system, bioflocs can be in ''brownian motion'' and the degradation rate of pollutants is increased.
Description
technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a biological carrier sewage treatment device. Background technique [0002] With the process of national industrialization and urbanization, the discharge of industrial sewage has increased significantly, and the treatment of sewage has become an urgent problem to be solved in sustainable development. For sewage containing a large amount of organic matter, a commonly used treatment method is biological Membrane method, biofilm method is a method of organic sewage treatment using microorganisms (biofilm) attached to the surface of certain solid objects. The biofilm first adsorbs organic matter attached to the water layer, and is decomposed by aerobic bacteria in the aerobic layer. , and then enter the anaerobic layer for anaerobic decomposition, and the flowing water layer washes away the aging biofilm to grow a new biofilm, and so on to achieve the purpose of p...
