Problems solved by technology

However, the current biological fillers have the following deficiencies: ①Inorganic material biological fillers are mostly hard porous materials with rough surfaces, which can provide a large specific surface area for microbial growth, and are cheap and easy to obtain
However, the hydrophilicity and biological affinity of general organic porous biofillers are slightly poor, and there are deficiencies in the speed of microbial film formation, the amount of film formation, and microbial activity, and spherical or spherical biofillers with better performance are difficult to produce, but easy to produce. The fluidization performance of the produced square biofiller is poor; ③At present, most of the biofillers are mainly surface-hanging film, and the amount of biofilm is small

Abstract

The invention relates to a novel aerobiont fluidized bed reactor and a technology thereof. The novel aerobiont fluidized bed reactor comprises a reactor tank, a water outlet, an exhaust valve, an air inlet, a water inlet, a sludge discharge pipe, swastika-shaped biological stuffing, an outer support, a flow meter, a water inlet pipe and a tilted plate settling pond. The technology for treating sewage by means of the novel aerobiont fluidized bed reactor comprises the steps that 1, sludge is acclimated; 2, the biological stuffing is added; 3, sludge is discharged after aeration is performed; 4, sewage is led in and then aeration is performed; 5, sludge is discharged; 6, the COD removal rate is calculated; 7, the fourth, fifth and sixth steps are repeatedly executed, and the amount of sewage to be treated and the sewage amount are increased gradually after the COD removal rate is higher than 50%; 8, the amount of the sewage to be treated reaches 25-50% of the effective volume of the reactor tank, and water outlet and backflow are started when the COD removal rate is higher than 80%; 9, the treated water is drained into the tilted plate settling pond through the water outlet.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a novel aerobic biological fluidized bed reactor and its technology. Background technique [0002] Biofilm method is a sewage aerobic biological treatment technology paralleled with activated sludge method. Its essence is to make microorganisms such as bacteria and fungi, micro-animals such as protozoa or metazoans attach to the filter material or some biological fillers to grow and multiply, and form a film-like biological sludge on it - biofilm . The sewage is in contact with the biofilm, and the organic pollutants in the sewage are used as nutrients, which are ingested by the microorganisms on the biofilm, the sewage is purified, and the microorganisms themselves are multiplied. [0003] Biological fluidized bed is a kind of sewage treatment equipment that was first researched and applied in the United States in the early 1970s. The aerobic biological f...
