Embodiment Construction

[0029] Orientation terms such as up, down, left, right, front, back, front, back, top, and bottom that are mentioned or may be mentioned in this specification are defined relative to their structures, and they are relative concepts. Therefore, it is possible to make corresponding changes according to its different positions and different usage states. Accordingly, these or other directional terms should not be construed as limiting terms.

[0030] The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of implementations consistent with aspects of the disclosure.

[0031] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless th...

Abstract

The invention discloses an up-flow hydrolytic acidification coupled pre-denitrification reactor. The up-flow hydrolytic acidification coupled pre-denitrification reactor comprises a reactor body, a central vertical shaft, a water inlet system, a water distribution system, a water outlet system and a denitrification filler area. Wherein an anaerobic sludge bulking bed formed by hydraulic stirring is arranged in the reactor body; the central vertical shaft is vertically arranged inside the reactor body; the water inlet system is arranged on the reactor body, the water outlet end of the water inlet system is communicated with the central vertical shaft, the water inlet end of the water inlet system is connected with a raw water pipeline, the water distribution system is arranged at the bottom of the reactor body, and the water outlet system is arranged at the top of an inner cavity of the reactor body; the denitrification filler area is arranged on the upper layer of the inner cavity of the reactor inner body. The up-flow hydrolytic acidification coupled pre-denitrification reactor solves the problems of high energy consumption and high carbon emission caused by excessive addition of a carbon source due to removal of total nitrogen in a sewage plant.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an upflow type hydrolysis acidification coupling pre-denitrification reactor. Background technique [0002] Industrial wastewater and park sewage usually have the problem of poor biochemical properties. The use of hydrolytic acidification process can greatly improve the biochemical properties of industrial wastewater. However, with the deepening of industrial production, the difficulty of industrial wastewater treatment gradually increases. Untreated The concentration and complexity of the sewage (raw water) are increasing year by year, and the optimization of the hydrolysis and acidification process is imminent. However, the high effluent total nitrogen / nitrate in the existing industrial wastewater and municipal sewage is difficult to meet the discharge standards, and the use of carbon sources in sewage plants is unreasonable. Most of the sewage from enterprises in the park has ...
