Problems solved by technology
[0002] The traditional A / O activated sludge method can effectively remove ammonia nitrogen and organic matter in sewage. This process usually requires the use of a sedimentation tank to separate the muddy water from the mixture output from the aerobic tank, and then the sludge deposited in the sedimentation tank is separated by the sludge return facility. Return to the anoxic tank to avoid the loss of sludge in the aerobic tank and the anoxic tank, which makes the process more complicated, with greater power consumption and higher operating costs

Embodiment Construction
[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to sewage treatment device and method. The sewage treatment device comprises an anoxic unit, an aerobic unit, a three-phase separator and a backflow unit, wherein the anoxic unit, the aerobic unit and the three-phase separator are sequentially arranged in the water inlet direction; the backflow unit communicates with the aerobic unit and the anoxic unit, and the anoxic unit is used for conducting denitrification treatment on sewage to be treated; the aerobic unit is used for carrying out aerobic treatment and nitrification treatment on a first mixture output by the anoxicunit, and the three-phase separator is used for carrying out gas-liquid-solid separation on a part of a second mixture output by the aerobic unit and can enable sludge separated from the three-phaseseparator to be conveyed back to the aerobic unit; and the backflow unit is used for conveying the rest of the second mixture output by the aerobic unit back to the anoxic unit. According to the sewage treatment device, a user can well maintain the sludge concentration in the anoxic unit and the aerobic unit without arranging a sludge reflux facility, so that the process flow is effectively simplified, the power cost is saved, and the power consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sewage treatment device and method. Background technique [0002] The traditional A / O activated sludge method can effectively remove ammonia nitrogen and organic matter in sewage. This process usually requires the use of a sedimentation tank to separate the muddy water from the mixture output from the aerobic tank, and then the sludge deposited in the sedimentation tank is separated by the sludge return facility. Return to the anoxic tank to avoid the loss of the sludge in the aerobic tank and the anoxic tank, which makes the process more complicated, the power consumption is larger, and the operating cost is higher. Contents of the invention [0003] Based on this, it is necessary to provide a sewage treatment device and method capable of effectively avoiding sludge loss in the anoxic unit and the aerobic unit. [0004] A sewage treatment device, comprising...
