Problems solved by technology
[0003] In the current conventional sewage treatment technology scheme, the reaction area is usually divided into multiple reaction pools by strict physical isolation, and many pipelines need to be erected to connect the reaction pools in related processes, which not only increases the pipeline erection process, but also increases the investment in pipelines In addition, it will lead to a substantial increase in the footprint of the entire treatment system, and it is not easy to maintain

Embodiment Construction
[0028] combine Figure 1 ~ Figure 3 As shown, this embodiment shows an integrated sewage treatment system, including a reaction pool. The interior of the reaction pool is divided into three functional areas according to the concentration gradient range of dissolved oxygen, which are anoxic area 1, micro-oxygen area 2, The aerobic zone 3, the anoxic zone 1, the micro-oxic zone 2, and the aerobic zone 3 are physically connected sequentially. The interior of the reaction zone is divided into three functional areas according to the gradient range of dissolved oxygen concentration. There is no physical separation between different functional areas. The plug-flow reaction does not need to set up a plug-flow device, which also saves the initial investment cost.
[0029] Further, a local anoxic zone 4 is provided in the aerobic zone 3; a sedimentation tank 5 is provided at the end of the aerobic zone 3, and an isolator 6 is provided between the sedimentation tank 5 and the aerobic zo...

The invention belongs to the technical field of sewage treatment, and relates to an integrated sewage treatment system and a sewage treatment method. The integrated sewage treatment system comprises a reaction tank, the interior of the reaction tank is divided into three functional areas according to a dissolved oxygen concentration gradient range, the three functional areas are an anoxic area, a micro-aerobic area and an aerobic area respectively, and the anoxic area, the micro-aerobic area and the aerobic area are sequentially communicated with one another physically. According to the conventional technology, functional areas are divided into different pools and pipelines are erected among the related pools; while the system is different from the conventional technology,different functional areas are divided according to the dissolved oxygen concentration gradient range and are not physically separated, so that the erection of numerous connecting pipelines can be avoided, and investment cost can be reduced, the head loss can be avoided, and a self-plug flow reaction can be realized. A sedimentation tank is arranged in a reaction area, the integration level is high, so that the system is simple in overall structure, capable of being remotely monitored and adjusted and convenient to operate and maintain, the area occupied by the system can be reduced, the operation cost can be controlled, and the system has great popularization value and wide application prospects.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated sewage treatment system and a sewage treatment method. Background technique [0002] With the continuous improvement of the urbanization rate and the continuous enhancement of the public's environmental protection awareness, environmental governance has gradually attracted widespread attention from all parties, especially the water pollution governance that is highly sensory, difficult to treat, and closely related to public health. [0003] In the current conventional sewage treatment technology scheme, the reaction area is usually divided into multiple reaction pools by strict physical isolation, and many pipelines need to be erected to connect the reaction pools in related processes, which not only increases the pipeline erection process, but also increases the investment in pipelines In addition, it will lead to a substantial increase in the...
