Problems solved by technology

[0004] In the above-mentioned patents, the sedimentation tank is directly realized by connecting pipes, one side is inputting sewage into the sedimentation tank, and the other side is pumping the settled sewage. However, in the process of inputting sewage, the input sewage will push the water flow in the sedimentation tank, and then Turn up the sediment settled at the bottom of the sedimentation tank, and the turned up sediment is easily discharged through the output pipeline, resulting in reduced effect of sedimentation or even failure

Abstract

The invention discloses a municipal sewage treatment system, which relates to the technical field of sewage treatment and comprises a pretreatment device, a biological treatment device, a sedimentation tank and an artificial wetland which are sequentially connected through pipelines. A plurality of drainage holes are provided on the side of the water inlet pipe close to one end of the sedimentation tank; a floating frame is arranged in the sedimentation tank, and a buffer film is arranged under the water inlet pipe in the floating frame. Aiming at the problem in the prior art that the sewage input sediment is easy to turn up, the present invention uses the buffer film to buffer the impact force of the sewage spray, and uses the floating frame to make the buffer film close to the liquid level in the sedimentation tank, so that the sewage can be smoothly input into the sedimentation tank , prevent the sediment in the sedimentation tank from being stirred up, and ensure the sedimentation effect of the sedimentation tank on sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, more specifically, it relates to a municipal sewage treatment system. Background technique [0002] China's per capita water resources are small and the spatial distribution is uneven. With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, and it is in the same important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. [0003] For the existing sewage treatment system, such as the Chinese patent with the patent publication number CN104402177B, it discloses a residential sewage treatment system, including grid equipment, grease traps, sedimentation tanks, aeration tanks, wetland systems, and membrane organisms. Reactor pools, sand filter pools, dosing and sterilization pools, reservoirs, a...
