Mobile Toilets Used in Beijing
Mobile toilets used in Beijing exhibit a diverse range of types and characteristics, covering aspects such as brands, materials, functions, technologies, operational models, prices, and application scenarios.
Brands and Materials: There are numerous brands of mobile toilets in Beijing, including Huajie Lvyuan, Yushijie, Yibingsi, Tengyuan Lvzhou, and others. The selection of materials is abundant. The outer shells are made of stainless steel, galvanized steel plates, plastics, color-coated steel plates, and metal carved panels, among others. The structural components mostly use high-density polyethylene or fiberglass-reinforced plastic, ensuring both strength and reduced self-weight to adapt to different environmental requirements.
Functional Modules: The water supply and drainage systems of mobile toilets are divided into 'self-circulating' and 'direct-discharge' types. The self-circulating type is equipped with clean water and wastewater tanks, enabling operation without external pipe networks through microbial degradation or vacuum suction technology. It is suitable for areas with weak infrastructure, such as parks and temporary construction sites. The direct-discharge type is directly connected to the municipal pipe network, making it suitable for long-term use in fixed locations.
Technological Iteration: In recent years, technology has focused on hygiene maintenance and odor control. New mobile toilets introduce foam sealing technology, using foaming agents to generate a dense foam layer that covers the toilet bowl, blocking visual contact and inhibiting ammonia gas emission, saving about 90% of water. Some units integrate negative pressure exhaust systems and activated carbon filtration devices, directing odors into filtration units through directional airflow to prevent external diffusion.
Operational Model: Dispatch management has shifted from manual inspections to digital platforms. Each toilet unit is equipped with sensors that monitor liquid levels, battery levels, and temperature and humidity in real-time. When the liquid level reaches a threshold, the system automatically sends a cleaning instruction, and a suction vehicle following the optimal route responds, improving operational efficiency.
Prices and Application Scenarios: In terms of pricing, for example, Beijing Environmental Sanitation's customized packing-box toilets for multi-person public toilets start at 1170.00 yuan, with a minimum order quantity of 2. The application scenarios are extensive, meeting short-term concentrated demands such as large-scale sports events, music festivals, and temporary markets. They fill the gap in public toilet services during the transition period of old urban area renovations. They can be relocated along with river treatment or road construction projects to avoid waste from secondary construction. Some cities have also attempted to combine them with rest stations for sanitation workers and small convenience service points to enhance resource utilization efficiency.
