Problems solved by technology

[0003] The main function of the existing drainage system is to discharge water, focusing on collecting rainwater and discharging it directly into the water body. However, since the sewage contains a large amount of harmful substances, direct discharge is likely to cause water pollution and waste of water resources.

Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] A municipal drainage system such as figure 1 Shown, comprise collection device 1, coarse filtration device 4, impurity removal device 7 and fine filtration device 10, wherein collection device 1 comprises collection tank 2 and several guide pipes 3 that are connected to collection tank 2, the other of guide pipe 3 One end is respectively connected to the road sewer and the building sewer; the sewage in the road sewer and the building sewer is collected into the collection tank 2 through the diversion pipe 3. The sewage from the source is pre-mixed in the collection tank 2, so that the pH value of the sewage is automatically adjusted. There is a water outlet for the sewage to flow out at the bottom of the collection tank, and the water outlet is connected to the coarse filtration device 4.

[0041] Such as figure 2 As shown, the coarse filter...

Abstract

The invention discloses a municipal drainage system, and aims to solve the problem that water pollution is easily caused when sewage is discharged directly. The key points of the technical scheme areas follows: the municipal drainage system comprises a collection device which comprises a collection tank and a plurality of flow guide pipes connected with the collection tank; a coarse filter devicewhich comprises a coarse filter tank connected with the collection tank, and a coarse filter mechanism arranged in the coarse filter tank; an impurity removing device which comprises an anaerobic decomposition mechanism and an aerobic decomposition mechanism connected in sequence, wherein the anaerobic decomposition mechanism is connected with the coarse filter tank; and a fine filter device which comprises a fine filter tank connected with the aerobic decomposition mechanism, and a fine filter mechanism arranged in the fine filter tank. The municipal drainage system provided by the inventioncan be used to preliminarily decompose and treat sewage, reduce the content of organic matter in the sewage, and reduce the pollution of the water body.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, more specifically, it relates to a municipal drainage system. Background technique [0002] The municipal drainage system is very important in people's daily life and in various sectors of the national economy. People's domestic water and rainwater are all sources of sewage. If the sewage is directly discharged into natural water bodies or soil, it will cause waste of water resources on the one hand. On the other hand, it will destroy the original natural environment. Therefore, in order to protect the environment and ensure the sustainable development of the national economy, modern cities must build a complete set of drainage system engineering facilities for collecting, transporting, treating and utilizing sewage. [0003] The function of the existing drainage system is mainly to discharge water, focusing on collecting rainwater and discharging it directly into the water body. Howe...
