Abstract

The invention relates to an efficient synchronized biological nitrogen and phosphorus removal combined device integrated with an anaerobic tank, an anoxic tank, an aerobiotic tank, a sedimentation tank and a sewage sludge recirculation process and a method thereof. Adjacent reaction tanks in the device share a same wall; a first anoxic tank, the anaerobic tank and a second anoxic tank are sequentially arranged from the front to the back; the right side of the first anoxic tank, the anaerobic tank and the second anoxic tank is provided with a corridor-type distribution channel, which supplies water respectively to the first anoxic tank, the anaerobic tank and the second anoxic tank through the water inlet pipes; a tank sludge tank, the sedimentation tank and a buffer zone are sequentially arranged from the front to the back and at the left side of the first anoxic tank, the anaerobic tank and the second anoxic tank; an outlet channel is arranged at the left side of the sedimentation tank; and the aerobiotic tank is arranged behind the buffer zone and the second anoxic tank. Through clever layout and reasonable design, the invention combines the biochemical tank and a secondary sedimentation tank to form an integrated process, so as to greatly reduce the construction cost and the occupied area.

Description

technical field [0001] The invention relates to a biological sewage treatment device and method, in particular to a highly efficient synchronous biological denitrification and phosphorus removal complex integrating anaerobic pool, anoxic pool, aerobic pool, sedimentation pool, and sewage sludge reflux process. Construction device and method. Background technique [0002] All biological nitrogen and phosphorus removal processes include alternating cycles of anaerobic, anoxic, and aerobic processes. According to the composition form, operation performance and operation mode of the structure, a variety of different treatment processes have been formed. At present, there are three main series of treatment processes applied to sewage treatment plants: ①Oxidation ditch series; ②A / O series; ③ Sequencing batch reactor (SBR) series. Among them, the A / O series has formed the current typical processes through continuous development and improvement: such as A 2 / O process, improved A...
