The invention provides sewage treatment equipment and a sewage treatment process, relates to the technical field of sewage treatment, and solves the technical problem in the prior art that water cannot be stably discharged when the water quality of incoming water is different or the water quality fluctuates. The sewage treatment equipment comprises a biological reaction cavity, a coagulation cavity, a precipitation cavity, a filtering cavity and a clear water cavity which are arranged in a tank body and are sequentially communicated, the biological reaction cavity is divided into a plurality of cavity bodies by a plurality of first wall bodies, and the first wall bodies are provided with communicating holes for communicating the adjacent cavity bodies; and aeration devices which are independently controlled are arranged in the plurality of cavities. According to the invention, by controlling the start and stop of each aeration device in the plurality of cavities, the aerobic and anoxic time in the biological reaction cavity is controlled to adapt to different incoming water qualities or water quality fluctuations, so that the effluent is stabilized, and the effluent quality is ensured.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment equipment and a sewage treatment process. Background technique [0002] With the development of my country's economy and the advancement of urbanization, the shortage of water resources and the aggravation of water pollution are becoming more and more serious. The requirements for sewage treatment and reuse are becoming more and more urgent, and the requirements for pollutant discharge standards are becoming more and more stringent. The currently used underground sewage treatment equipment has the advantages of not occupying a large area of ground space and not affecting the appearance. An underground sewage treatment equipment in which a regulating tank, anoxic tank, biological contact oxidation tank and two sedimentation tanks are sequentially distributed in the box. The sewage is treated by fixed treatment methods such as fixed nitrification and d...
