The invention provides a rainwater and sewage diversion well. The rainwater and sewage diversion well comprises a diversion well chamber, a confluence pipe, a sewage pipe and a rainwater pipe, wherein a first chamber is arranged in the diversion well chamber, the confluence pipe and the sewage pipe are respectively communicated with the diversion well chamber, an overflow hole is formed in one side of the diversion well chamber, the rainwater pipe is communicated to the overflow hole, and a one-way valve which forms a passage from the first chamber to the rainwater pipe is arranged on the overflow hole. The rainwater and sewage diversion well provided by the invention has the advantages that diversion of sewage and rainwater can be realized in the diversion well chamber, when water reaches the position of the overflow hole, the rainwater can flow into the rainwater pipe from the overflow hole, and daily sewage flows out from the sewage pipe, so that diversion is realized; and the one-way valve arranged on the overflow hole isolates odor in a sewage system under the condition that the rainwater and the sewage can normally pass through, so that the odor is prevented from overflowing.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rainwater and sewage diversion well. Background technique [0002] Due to historical reasons, the drainage system in the old built-up areas of the city mostly adopts the combined system, and the rainwater and sewage share the municipal drainage pipes, which is easy to cause problems such as overflow, backflow, and pollution of rivers and lakes. With the needs of urban development, new areas in cities and towns are required to adopt a diversion system, and the combined drainage system in old built-up areas should implement rainwater and sewage diversion reconstruction. The renovation process generally involves rainwater and sewage diversion facilities. In the traditional rain and sewage diversion facilities, the sewage system and the rainwater system lack isolation facilities. In summer, the odor in the diversion facility is connected to the outside through the rainwate...
