Vacuum sewage collecting and treating system

Abstract

The invention discloses a vacuum sewage collecting and treating system. The vacuum sewage collecting and treating system comprises a sewage gathering pipeline, a vacuum collection well, a vacuum conveying pipeline, a vacuum pump station and a sewage treating device, wherein the sewage enters the vacuum collection well through the sewage gathering pipeline; when the sewage collected in the well reaches a certain amount, the sewage enters the vacuum pump station along the vacuum conveying pipeline; when the liquid level of the sewage in a vacuum sewage storage tank reaches a predetermined liquid level, the sewage conveying pump is started and is used for conveying the sewage to the sewage treating device to purify the sewage. Through the vacuum sewage collecting and treating system, the domestic sewage collection method is changed from the conventional gravity collection into vacuum collection; the sewage treatment is charged from a manner of discharging the sewage into a sewage pipe net and carrying out centralized treatment on the sewage to a process of carrying out on-site treatment by using a small integrated membrane treatment device; collection and treatment are integrated to a complete set of system; the system is not limited by basic supporting facilities and is not required to relay on urban drainage facilities; the system is integrated with the ecological environmental protection technology with efficient collection and efficient treatment functions and is especially suitable for regions such as small towns and countries and the like in which sewage treatment plants are unsuitably built.

Description

technical field [0001] The invention belongs to the field of sewage collection and treatment, and in particular relates to an integrated and miniaturized system that uses vacuum technology to realize sewage collection and treatment. Background technique [0002] In cities and densely populated areas, gravity pipelines are often used to collect sewage. The sewage in buildings flows into outdoor inspection wells. The sewage pipelines are laid according to a certain slope. The sewage is transported along the pipeline to the sewage lifting well by gravity, and then pumped The station is upgraded to the sewage treatment facility. In order to prevent the sewage in the pipeline from clogging, it is often necessary to adopt a certain slope when laying the pipeline. Therefore, the sewage pipeline is generally buried relatively deep, and the project investment is high. [0003] With the acceleration of my country's urbanization process, the pressure of sewage treatment in small towns ...

Problems solved by technology

[0005] 1. It is easily restricted by the terrain, not suitable for places with many undulations, shallow rock layers or unstable soil, not suitable for residential areas with high water levels in the surrounding waters or areas where pits should not be excavated too deep;

[0006] 2. It cannot be flexibly coordinated with other professional pipelines as a whole, and it is not suitable for residents to live in scattered areas or places where other municipal and other public facilities have been buried underground;

[0007] 3. Larger slopes and buried depths ar
