Mobile Toilet at Yulong Snow Mountain

The mobile toilet at Yulong Snow Mountain adopts Zhongheng Yuantai's vacuum toilet technology, which offers core advantages such as water conservation, freeze resistance, adaptability to extreme environments, and low operation and maintenance costs, providing a reliable environmental protection solution for high-altitude scenic spots.

1. Efficient Water Conservation, Breaking Traditional Limits
The vacuum toilet technology achieves rapid sewage discharge through negative pressure suction, with a single flush volume of ≤0.8L, saving over 80% of water compared to traditional water-flush toilets. In extreme water-saving mode, the flush volume can be as low as 0.5-1L, with a water-saving rate exceeding 90%. Taking the Ganzi Honghaizi project as an example, it served 20,000 people during the National Day holiday using only 10 tons of water, significantly reducing water consumption, especially suitable for high-altitude areas with scarce water resources.

2. Freeze and Blockage Prevention, Adapting to Harsh Cold Environments
The vacuum drainage system adopts a dry operation structure with no residual water in the pipes, eliminating the risk of freezing and cracking from the source. The equipment can operate stably in a wide temperature range from -30℃ to +50℃ and has been verified in extreme scenarios such as Yulong Snow Mountain at an altitude of 4,506 meters and the Everest Base Camp at an altitude of 5,200 meters. Its self-developed self-pulverizing vacuum pump can crush and transport excreta, eliminating blockage issues and thoroughly solving the pain point of traditional toilets being prone to freezing and blockage in high-cold areas.

3. Verification of Extreme Environment Adaptability
This technology has been operating stably for years in high-altitude areas such as Yulong Snow Mountain and the Everest Base Camp, and has covered national-level projects such as the post-disaster reconstruction of Jiuzhaigou and the Jiuquan Satellite Launch Center. Its core components are designed to be resistant to ultraviolet rays and sandstorms, enabling them to withstand extreme conditions such as strong ultraviolet rays and low air pressure, demonstrating the technology's cross-scenario applicability.

4. Environmental Protection and Operation and Maintenance Cost Advantages
The vacuum toilet does not need to be connected to the municipal sewer network, with pipe diameters only one-third of those of traditional toilets, reducing the construction period by 70%. Taking the Ganzi Honghaizi project as an example, the average monthly operation and maintenance cost is only 3,000 yuan, and it achieves zero pollution emissions. After being suctioned by the vacuum pump into the sewage collection tank, the sewage can be regularly transported and treated by sewage suction trucks, avoiding soil and groundwater pollution and meeting the ecological protection requirements of scenic spots.

5. Technological Endorsement and Iterative Capability
Zhongheng Yuantai holds 72 core patents, and its vacuum pump technology is continuously optimized through the joint R&D base with the Chengdu Institute of Biology, Chinese Academy of Sciences. The technical team has optimized the performance of the vacuum pump for the low air pressure environment in high-altitude areas, ensuring system stability and forming a full-chain technical guarantee from design to operation and maintenance.
