Tianjin Binhai Rental Mobile Toilets
Tianjin Binhai's rental mobile toilets effectively address the challenges of sanitation facility deployment in port and industrial clusters through technological innovation and service optimization. The core solutions are reflected in the following aspects:
1. Excreta Treatment Technology Adapted to Special Environments
In response to the geological conditions of coastal saline-alkali land and the high-temperature climate in summer, Haoshitong Pipeline Engineering (Beijing) Co., Ltd. employs a fully enclosed sewage storage tank and vacuum suction system. This system rapidly transports excreta to a central storage tank through negative pressure pipelines, with a single suction time shortened to within 5 seconds, significantly reducing odor retention time. The sewage storage tank is made of corrosion-resistant alloy to prevent erosion by saline-alkali soil, and it is equipped with a constant-temperature heating device to prevent excreta fermentation and odor generation caused by high temperatures.
2. Ventilation System Design Optimized with Meteorological Data
The service plan integrates local prevailing wind direction data, orienting the toilet inlets toward the southeast (the prevailing wind direction in Tianjin Binhai in summer) and placing the outlets on the northwest side. Through combined treatment with activated carbon filters and ultraviolet sterilization devices, the odor concentration can be reduced by 60%-70%. For example, during high-temperature periods in summer, the system automatically increases ventilation frequency, coupled with the filter's automatic replacement function every 2 hours, ensuring air quality standards are met.
3. Intelligent Management in the Transportation Process
The liquid level in the storage tank is monitored in real-time via GPS, with data synchronized to the dispatch center. When the liquid level reaches the 85% threshold, the system automatically plans the optimal route and contacts the sewage treatment plant, achieving off-peak transportation and avoiding overflow risks. The transportation vehicles are equipped with double-layer sealed tanks to prevent leaks during transit, and a nighttime low-temperature transportation strategy is adopted to reduce odor diffusion.
4. Dynamic Response Mechanism Ensures Usage Efficiency
Toilet modules are distributed according to the heatmap of foot traffic at the site. When the usage load of a group of toilets reaches 80% of the design capacity, the dispatch center predicts peak demand using AI algorithms and arranges for a refilling vehicle to arrive 15 minutes in advance. The refilling vehicle is equipped with a quick-connect device, with a single refilling time controlled within 90 seconds, reducing user waiting time to within 3 minutes.
Application Scenarios: This service has covered temporary event venues such as construction sites, music festivals, marathons, and concerts. For example, in the Tianjin Port Container Terminal renovation project, by deploying 20 mobile toilet modules, it met the daily toilet needs of 2,000 people without any odor complaints or equipment failures.
