Outdoor Vacuum Sewage System
The outdoor vacuum drainage system of Juchuan is a kind of drainage system, which produces high-speed air flow containing sewage by means of air pressure difference and takes the sewage away from the appliance. As a new type of drainage system, compared with the traditional gravity drainage system, Juchuan vacuum drainage system can not only effectively save water and protect the water resource environment, but also has the advantages of pipe network not limited by the terrain, convenient installation, not easy to block, relatively small pipe diameter, good economic performance, etc.
There are two types of sewage collection pipeline systems:
Traditional gravity sewage collection system
Vacuum sewer system with vacuum extraction
Compared with the traditional gravity collection system, the vacuum collection system has the following advantages:
Small pipe diameter, small excavation area and shallow excavation depth
Low construction cost
Easy construction and short construction period
Adopt vacuum negative pressure flow, up to 7m / s, strong scouring effect, pipeline is not easy to block
Not affected by local soil geological conditions and groundwater level
Little impact on local road traffic
Comparison of gravity flow network and vacuum drainage network
Comparison table between vacuum system and gravity drainage system
Comparison Items | Gravity flow sewage collection scheme | Vacuum sewage collection scheme |
Sewage collection ideas | Fragment collection treatment | Centralized processing |
Characteristics of sewage collection and transportation | Gravity flow, no power, but the pipeline needs to maintain a certain slope | Negative pressure mode, the vacuum station needs to provide power, and the pipeline can be partially lifted |
Characteristics of sewage pipe system | Large pipe diameter (DN100 ~ 300), buried deep (1 ~ 3.5m) | Small pipe diameter (DN75 ~ 150), shallow depth (1.0 ~ 1.5m) |
Pipeline laying flexibility | The buried depth increases rapidly when the terrain and pipeline slope are reversed; It is necessary to set up lifting pump station when crossing river gully; When laying in the same trough as the water supply pipeline, it should be set under the water supply pipeline | The pipeline can be lifted when the terrain and the pipeline reverse slope; When crossing the river gully, it can be U-shaped or directly overhead. It can be laid side by side when it is in the same trough as the water supply pipeline |
Possibility of pipe blockage | In most cases, the flow rate in the sewage pipe is less than 0.6m/s, which is easy to clog | The gas and water mixture in the pipe has high flow rate, strong scouring effect, and is not easy to clog |
Possibility of pipeline leakage | Commonly used pipes are reinforced concrete pipes, HDPE double-wall corrugated pipes, socket interfaces, which are easy to leak and pollute groundwater under external force or uneven settlement | The commonly used pipe is PE pipe, PVC-U pipe, hot melt connection or bonding interface, which is not easy to leak |
Construction difficulty | The roadway in the village is narrow, the sewage pipe diameter is large, the burial is deep, the inspection well is many, the excavation amount of stone is involved, and the construction is difficult | The sewage pipe diameter is small, the buried depth is shallow, the valve well is less, the excavation amount of stone is less, the construction difficulty is small, and the gravity flow pipe can also be used for pipe construction, which greatly saves the construction cost |
Power supply requirements | Multiple lifting pump pumping stations are required for power supply, and multiple sets of water treatment devices are required | Vacuum collection well is purely mechanical control, no power supply, only vacuum pump station power supply. |
Power Consumption | Need multiple lifting pump station power supply, energy consumption is average | Low energy consumption, per ton of water collection energy consumption only 0.1 yuan |
Management and Maintenance | The pipeline is easy to clog, the management and maintenance workload is large, and the technical level of management and protection personnel is low | The pipeline is not easy to be silted, and the management and maintenance workload is less, but the technical level of the management and protection personnel is required to be high |
Juchuan outdoor vacuum drainage can be widely used:
Rural sewage collection
The rural area has the characteristics of complex terrain, dense houses, narrow roadway, shallow rock layer and deep frozen layer, so it is difficult to use the traditional gravity flow drainage system for village drainage collection. Vacuum sewage collection technology can well adapt to the characteristics of rural topography and make up for the application defects of traditional gravity collection, with the advantages of low energy consumption and short construction period.
Mountainous areas or areas with dense water networks
In particular, mountain villas and water view villas, as well as the old city (especially the ancient city with cultural relic value) reconstruction projects that are excavated on a large scale without any conditions are unable to do their best. A large number of lift pump stations or inverted siphon roads need to be set up, which greatly increases the construction difficulty and operation and maintenance costs. The vacuum drainage system provides us with a new design concept Solve the above problems better.
Water source protection area and area with high groundwater level
Due to the advantages of good airtightness and no leakage of vacuum drainage pipeline, it can be used in water source protection area to avoid sewage leakage polluting the water source. At the same time, in the area with high groundwater level, it can also avoid the reverse infiltration of groundwater into the sewage pipeline, resulting in increased load of sewage treatment plant.
Ecologically sensitive area, sandy land, waterfront area
Under the condition of shallow groundwater and quicksand, if the traditional gravity drainage system is adopted, the buried depth of the pipe network is deep. Because of the rich groundwater, the quicksand phenomenon of excavation project is serious, and the excavation is difficult. The pipe network of vacuum drainage system is shallow and less excavated, which is suitable for sandy land and waterfront area.
Ecological drainage system
Ecological drainage advocates source classification and source control of domestic wastewater, i.e. separate collection and recycling of human excreta, decentralized and near source treatment of domestic wastewater to avoid long-distance transmission and mixing of wastewater from different sources, and high cost of water delivery pipe network. Vacuum toilet and vacuum drainage can be used to collect high concentration feces and urine separately The mixture of feces and urine is properly treated and reused in farmland
Adjacent to the lake and sea resort, the drainage system of the scenic spot
The vacuum drainage system is flexible in size and can be used in areas with large sewage flow, such as resort, scenic tourist area, etc.
