Embodiment Construction

[0037] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0038] As mentioned above, the biological method is one of the main methods for denitrification and phosphorus removal of sewage currently used. Both the biological denitrification process and the biological phosphorus removal process need to consume organic matter, that is, both require organic carbon sources. Therefore, when the organic matter carbon in raw water When the amount of carbon sources is insufficient, it is impossible to meet the demand for carbon sources of biological denitrification and biological phosphorus removal at the same time. In addition, according to the principle of biological denitrification and biological phosphorus removal, biological denitrification requires treatmen...

Abstract

The invention discloses a biological nitrogen and phosphorus removal device which comprises a nitration reaction unit, a sequencing batch biological reaction unit, a first middle pool, a second middle pool, a first water outlet pipeline, a water draining pipeline, a discharging pipeline, a water inlet pipeline, a third water outlet pipeline, a first air pipeline, a second air pipeline, a first air supply device and a second air supply device, wherein the first middle pool and the second middle pool are arranged between the nitration reaction unit and the sequencing batch biological reaction unit at an interval and are formed into a closed loop; the nitration reaction unit is communicated with the first middle pool through the first water outlet pipeline and the water inlet pipeline and is communicated with the second middle pool through the third water outlet pipeline; and the sequencing batch biological reaction unit is communicated with the first middle pool through the discharging pipeline and is communicated with the second middle pool through the water draining pipeline. The device can solve the contradiction of different sludge updating speeds required by biological nitrogen removal and phosphorus removal, can realize reusability of the carbon source in the nitrogen removal and phosphorus removal processes, and can increase the efficiency of treating sewage and wastewater.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a biological denitrification and dephosphorization device, which can realize reuse of carbon sources. The device is mainly used in the treatment of domestic sewage, industrial waste water, etc., and belongs to the category of environmental protection. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Nitrogen and phosphorus are the main elements that cause eutrophication of water bodies. Nitrogen and phosphorus removal from domestic sewage and industrial wastewater is an important content in the field of water treatment. Biological method is one of the main sewage nitrogen and phosphorus removal methods currently used, and is widely used in urban sewage treatment, rural sewage treatment and industrial wastewa...
