Novel urban vacuum sewage discharge system

Abstract

The invention relates to the technical field of vacuum defecation collecting systems, in particular to a novel urban vacuum sewage discharge system. A vacuum pump station comprises a vacuum transfer tank, a water separating tank, a first water circulating vacuum pump, a self-suction sewage discharge pump, a one-way valve, a water inlet solenoid valve and a pressure release valve; the vacuum transfer tank communicates with an outside atmosphere through an air pipeline and communicates with a septic tank through a sewage discharge pipeline; the self-suction sewage discharge pump is arranged on the sewage discharge pipeline between the septic tank and the vacuum transfer tank; the vacuum transfer tank is connected with the first water circulating vacuum pump through a gas pumping pipeline; the first water circulating vacuum pump communicates with the water separating tank through a gas discharging pipeline; a water inlet of the water separating tank communicates with an outside water source through a water inlet pipeline, and the water inlet solenoid valve is arranged on the water inlet pipeline between the outside water source and the water separating tank; and a gas outlet of the water separating tank communicates with the outside atmosphere, and all toilet stool units communicate with a sewage inlet of the vacuum transfer tank through discharging pipelines. The novel urban vacuum sewage discharge system saves energy and water and can remove the foreign odor in sewage.

Description

Technical field [0001] The invention relates to the technical field of vacuum feces collection systems, in particular to a new type of urban vacuum sewage system. Background technique [0002] For toilets in public places such as trains, vacuum sewage systems are often used to control sewage discharge. The vacuum sewage system existing in the prior art usually uses an independent system for one toilet, which cannot realize one system to control multiple toilets, and the energy consumption is large. In the process of sewage discharge, it is easy to produce peculiar smell and affect the external environment. Summary of the invention [0003] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a new type of urban vacuum sewage system, which can save energy and water, eliminate peculiar smell in the sewage, and realize long-distance sewage discharge. [0004] The technical scheme adopted by the present invention is as follows: a new...

[0002] For toilets in public places such as trains, vacuum sewage systems are often used to control sewage discharge. The vacuum sewage systems in the prior art usually use an independent system for one toilet, which cannot control multiple toilets with one system, and consumes a lot of energy. During the sewage discharge process, it is easy to produce peculiar smell and affect the external environment
