Abstract

The invention provides an efficient energy-saving type multi-mode enhanced denitrification sewage treatment system. The system comprises an anaerobic zone, an anoxic zone, an aeration zone I, a maneuvering zone, an aeration zone II, a rear anoxic zone and an aerobic zone which are connected in sequence, wherein a sludge regeneration area is arranged at the upper part of the anaerobic area; two water outlets are formed in the anaerobic zone and are respectively connected with the sludge regeneration zone and the anoxic zone; gates are arranged on the two water outlets to control the flow direction of water in the anaerobic zone; the aeration zone I and the aeration zone II are aerobic tanks or aeration anoxic tanks; and the maneuvering zone is an aerobic tank, an anoxic tank or an aerationanoxic tank. The system adopts a novel sewage treatment process developed on the basis of a traditional multi-stage AO process, and the core of the process is to combine an aeration anoxic process anda multi-stage AO process together, so that short-cut denitrification can be realized; and a plurality of water inlet points, multi-section backflow and precise aeration system control are arranged, so that sewage treatment systems in various modes can be formed, and different water outlet requirements can be met.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency and energy-saving multi-mode enhanced denitrification sewage treatment system. Background technique [0002] As water environment protection is paid more and more attention, the effluent standard of sewage treatment plants needs to be continuously improved. However, under the new requirements and high standards, the traditional sewage treatment process can no longer meet the requirements. Generally speaking, the traditional sewage treatment process includes A 2 O process, improved A 2 O process, MUCT process, oxidation ditch process and SBR process, etc., all of these processes have the problems of poor total nitrogen removal effect and high energy consumption. Therefore, it is necessary to design an efficient and energy-saving multi-mode enhanced denitrification wastewater treatment system. Contents of the invention [0003] Aiming at the problems...
