Embodiment 1

[0023] Embodiment 1: as figure 1 , figure 2 As shown, a sewage lifting system is used for the layout of rural sewage pipe networks, including a group of collection wells 1 connected to the atmosphere, which are distributed near each household to collect sewage from each household. A vacuum collection tank 2 is also provided, and a vacuum pump is used to generate negative pressure for collecting sewage from each collection well 1, and a vacuum delivery pipeline 3 connecting the collection well and the vacuum collection tank 2 is provided between the collection well 1 and the vacuum collection tank 2 .

[0024] When the height difference between the collection well 1 and the vacuum collection tank 2 is less than the height that the vacuum collection tank 2 can lift, the sewage in the collection well 1 can be smoothly transported to the vacuum collection tank 2 through the vacuum delivery pipeline 3 . When the height difference between the collection well 1 and the vacuum col...

Embodiment 2

[0027] like figure 1 , Figures 3 to 6As shown, a sewage lifting system is used for the layout of rural sewage pipe networks, including a group of collection wells 1 connected to the atmosphere, which are distributed near each household to collect sewage from each household. A vacuum collection tank 2 is also provided, and a negative pressure is generated by a vacuum pump to collect sewage from each collection well 1, and a vacuum conveying pipe connecting the collection well 1 and the vacuum collection tank 2 is arranged between the collection well 1 and the vacuum collection tank 2 Road 3. A group of lift shafts 5 are arranged in series on the vacuum conveying pipeline 3, and a bypass pipe 7 is arranged above the lift shaft 5. One end of the bypass pipe 7 communicates with the top of the lift shaft 5, and the other end communicates with the drain pipe. The top of 6 is connected; the bypass pipe 7 is provided with a bypass valve 8, and the top of the lifting shaft 5 is also...

Abstract

The invention discloses a sewage lifting system. The sewage lifting system comprises a group of collecting wells communicated with atmospheres, vacuum collecting tanks and vacuum conveying pipelines which communicate the collecting wells with the vacuum collecting tanks. A group of lifting wells are arranged in series on the vacuum conveying pipelines, the lifting wells are of a closed tank structure, water inlets and water outlets separately connected with the vacuum conveying pipelines are formed in the lifting wells, drain pipes with one ends extending into the bottoms of the lifting wellsare arranged in the lifting wells, and the other ends of the drain pipes communicate with the drain pipes in a abut-joint mode; by-pass pipes are arranged above the lifting wells, one ends of the by-pass pipes communicate with the tops of the lifting wells, and the other ends of the by-pass pipes communicate with the tops of the drain pipes; by-pass valves are arranged on the by-pass pipes, air suction valves are arranged at the tops of the lifting wells, and control switches for controlling the opening and closing of the by-pass valves and the air suction valves are further arranged on the lifting wells. According to the sewage lifting system, the problem that the vacuum collecting tanks cannot collect sewage from the collecting wells beyond the height of a negative pressure theory to thevacuum collecting tanks is solved.

Description

technical field [0001] The invention relates to the technical field of comprehensive treatment of rural sewage, in particular to a sewage lifting system. Background technique [0002] In recent years, with the country's vigorous promotion of new rural construction and beautiful rural construction, rural sewage collection and treatment related to rural water environment management has received key support from the state and local governments and has developed rapidly. Rural sewage pipe network has become a trend. Rural domestic sewage includes washing, bathing, kitchen cooking, excrement and its flushing, etc. It has the characteristics of wide dispersion, multiple sources, rapid growth, complex sewage components, and large changes in water quality and water volume. A typical rural sewage collection and treatment system usually consists of a sewage pipe network system (user exit pipes, household septic tanks with three or two compartments, sewage pipe network, intermediate li...
