Problems solved by technology

However, the non-pressure transportation of sewage pipelines, the setting of inspection wells and the buried depth of pipelines all restrict its inclusion in the comprehensive pipe gallery, which also prevents the advantages of the comprehensive pipe gallery from being fully highlighted in municipal engineering.
The non-pressurized sewage pipeline is not conducive to being incorporated into the comprehensive pipe gallery, and cannot completely eliminate the urban "pull link", and cannot reflect all the advantages of the construction of the pipe gallery

Abstract

The invention discloses a distributed sewage pre-treatment system which comprises an outer shaft (1), a central shaft (2), a water inlet pipeline (3) and a water outlet pipeline (4). A sewage storagezone (5) is formed between the lower end of the central shaft (2) and the bottom of the outer shaft (1), a cylindrical overflow dam (6) is arranged between the central shaft (2) and the outer shaft (1), the lower end of the overflow dam (6) is connected with the central shaft (2) through a connecting base plate (7), a water suction well (8) is formed between the overflow dam (6) and the central shaft (2), a water pump (9) is arranged in the water suction well (8) and is connected with the water outlet pipeline (4), and the water inlet pipeline (3) can discharge sewage into the sewage storage zone (5). The distributed sewage pre-treatment system can store and pretreat sewage and delivers the sewage to a sewage treatment plant for further centralized treatment through a non-pressure sewage pipeline and a comprehensive pipe gallery after in-situ pressurized lifting.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a distributed sewage pretreatment system. Background technique [0002] The current municipal sewage treatment system is mainly a centralized treatment system, that is, after the sewage within the designated sewage discharge range is collected, it will be transported to the sewage treatment plant through the non-pressure pipe network system for unified and centralized treatment. In the centralized treatment method, the sewage pipes are transported through lower buried depths, and the investment in the municipal pipe network accounts for 60% to 70% of the investment in sewage treatment. [0003] For example, the sewage pipes are buried with a certain slope, and the sewage in the designated sewage area is transported to the sewage treatment plant in a non-pressure pipeline for treatment. The sewage pipes need to be equipped with inspection wells at intervals of tens of meters accord...
