Embodiment
[0016] Embodiment: refer to attached figure 1 , the sewage treatment pool with integrated structure is divided into three grids, which are the first treatment unit (1), the intermediate treatment unit (2) and the second treatment unit (3), and the water inlet pipe (7) passes through the electric valve (8) The three processing units are respectively connected. The three processing units are rectangular and have the same size. Each unit is hydraulically connected to form an integrated structure. The intermediate processing unit (2) is provided with a biological carrier (10) made of elastic filler.
[0017] The intermediate treatment unit (2) is equipped with four sets of compound leaf submerged aerators (9) to form an oxygenated aeration zone, and two sets of sludge return pumps (4) are installed at the bottom of the intermediate treatment unit (2) for feeding The treatment tank refluxes the mixed solution. The first treatment unit (1) and the second treatment unit (2) located ...

The invention relates to a high efficiency and low consumption comprehensive town sewerage treatment method, which comprises an integrated rectangular reaction tank that is divided into three units, namely a middle unit (2), a treatment unit (1) and a treatment unit (3); the three units are communicated by hydraulic power; feeding water can enter the three units by switching an electrically operated valve (8); continuous water feeding and discharging are operated periodically and alternately; the middle unit (2) of a biochemical reactor is operated continuously; as an aerobic contact oxidation pond, the middle unit (2) is additionally provided with a biochemical carrier (10), an aeration system and an internal reflux system; reflux mixed liquor is transferred to the treatment unit (1) and the treatment unit (3) by the internal reflux system; both the treatment unit (1) and the treatment unit (3) are provided with a circulatory flow stirrer (5), a water discharging weir (6) and a sludge outlet (11); the treatment unit (1) and the treatment unit (3) are used as an anaerobic tank, an anoxic tank and a sedimentation tank alternatively. The invention has the advantages of simple operation, high operation efficiency, low investment cost, etc.
Description
technical field [0001] The invention belongs to the field of sewage treatment environmental protection engineering, and in particular relates to a high-efficiency and low-consumption urban comprehensive sewage treatment technology. Background technique [0002] In the process of sewage treatment, in order to meet the national sewage discharge standards, general sewage adopts a process from primary physical treatment to secondary biochemical treatment. For biochemical treatment, SBR method, oxidation ditch and ICEAS sequencing batch method are widely used at present, and there are also variations of SBR method, such as circulating activated sludge method (CAST). The current hot spot is the integrated activated sludge treatment process of aeration and sedimentation, that is, the aeration and sedimentation processes are completed in the same reactor. Small size, low investment cost, etc. Since the reaction is run in one reactor, different states such as aeration, anoxic and an...
