Problems solved by technology

[0004] 1. If a large-scale pipeline transformation is implemented in the area, there will be a considerable amount of investigation work in the early stage, and the implementation of the project will involve a wide range of areas, difficult implementation, long construction period, and large project investment.
[0005] 2. The space of the inner alleys in the riverside belt is narrow, and there are existing pipelines, so it is difficult to add sewage interceptors, so it is not suitable to implement the project of laying sewage interceptors in the inner alleys
[0006] 3. The diameter of the gravity pipeline is relatively large, so the pipe hanging along the river bank has high requirements for the stability of the river barge, which affects the landscape on both sides of the river. At the same time, the large diameter of the pipe makes it inconvenient to take over the pipe, which is easy to block and requires a cleaning port, which is inconvenient for management
[0007] 4. The excavation of buried pipes along the river requires a large slope and buried depth, and auxiliary structures such as sewage inspection wells, lifting pump stations or inverted siphons need to be installed, resulting in a significant increase in construction difficulty, construction costs, and operation and maintenance costs

Abstract

The invention discloses a vacuum sewage interception system which is suitable for erecting pipes coastwise. The vacuum sewage interception system comprises a control unit, a sewage collecting pipeline, a vacuum valve well, a vacuum pipeline and a vacuum pump station, wherein the sewage collecting pipeline is connected with the vacuum valve well; a water pumping pipe connected with the vacuum pipeline is arranged in the vacuum valve well; a vacuum interface valve is arranged between the water pumping pipe and the vacuum pipeline; the vacuum pump station comprises a vacuum tank, a vacuum pump and a sewage pump; the vacuum pipeline is connected with the vacuum tank; the vacuum tank is connected with the vacuum pump and the sewage pump by a pipeline respectively; and a control unit controls the turn-on and turn-off of the vacuum interface valve, controls the vacuum pump to keep air pressure in the vacuum tank within the set negative pressure range when at least the vacuum interface valve starts and controls the sewage pump to discharge sewage. The invention also discloses a vacuum sewage interception method for erecting the pipes coastwise. By the vacuum sewage interception system and the vacuum sewage interception method, the defect of gravity sewage interception in riparian zones of old towns is overcome, the investment of capital construction is saved, the running stability of the system is improved, and the system is convenient to maintain and manage daily.

Description

technical field [0001] The invention relates to sewage interception technology, in particular to a vacuum sewage interception system and method suitable for erecting pipes along the coast. Background technique [0002] In traditional riverside sewage interception projects, sewage interceptors are generally installed in the surrounding downstream urban sewage pipes, and directly discharged to municipal underground pipes; if there are no urban pipes, urban sewage pipes are first built, and then sewage interceptors are installed. According to different layout forms, the traditional gravity sewage interception technology can be divided into the following four types: (1) Large-scale reconstruction of residential areas and unit pipeline systems along the river to implement rain and sewage diversion; Set sewage interceptors in parallel lanes; (3) erect sewage interceptors along the river bank; (4) excavate and bury sewage interceptors along the river bank. [0003] Due to the earl...
