Abstract

The invention discloses a constructed wetland denitrification sewage treatment device and a sewage treatment method, and relates to the technical field of sewage treatment.The constructed wetland denitrification sewage treatment device comprises a first pool body and a second pool body arranged on one side of the first pool body, a liquid inlet pipe is connected to one side of the first pool body in an inserted mode, and first partition plates distributed at equal intervals are fixedly connected to the interior of the first pool body; an opening is formed in one side of the first partition plate, an overflow pipe is fixedly connected to the circumferential inner wall of the opening, a control valve is arranged on the circumferential outer wall of the overflow pipe, and an anaerobic tank, an aerobic tank and a micro-aerobic tank are arranged in the first tank body from left to right. Carbon pollutants in sewage can be efficiently degraded, the sewage finally flowing into the micro-aerobic tank is subjected to short-cut nitrification and denitrification constructed wetland treatment, a small amount of oxygen is dissolved in water under the synergistic effect of aeration and plant root system oxygen secretion, a proper environment is provided for short-cut nitrification and denitrification, and the sewage treatment effect is improved. The nitrogen pollutants in the sewage are efficiently removed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an artificial wetland denitrification sewage treatment device and a sewage treatment method. Background technique [0002] Constructed wetland is a sewage treatment technology that strengthens its purification ability through artificial construction and supervision and control based on the principle of natural wetland purification of sewage. It is a complex system composed of a permeable substrate, plants, water bodies, aerobic or anaerobic microbial populations and animals. After the sewage is treated in the constructed wetland, including biodegradation, filtration, precipitation and adsorption, the organic compounds, suspended solids, some nitrogenous compounds, phosphorus and pathogenic bacteria in the sewage have been greatly reduced. [0003] The Chinese invention patent with the publication number CN104291445A in the prior art discloses a constructed wetland denit...
