Chengtou Mobile Toilet

Chengtou mobile toilets refer to portable toilet facilities used in cities, providing public restroom services with flexible deployment and diverse functions.

I. Basic Composition
Urban mobile toilets typically consist of fecal sewage storage tanks (or disposal units), flooring, sanitary fixtures, walls, washing equipment, water tanks, roofs, and mobility devices. Their structural forms are divided into single-unit structures (independent units) and composite structures (multi-module combinations). Mobility methods include hoisting and handling types (requiring mechanical assistance) and powered towing types (capable of self-movement or towing by trailers). Sewage treatment methods cover flushing types (relying on water supply and drainage systems), waterless suction types (regular fecal transportation), recirculating flushing types (purified wastewater reuse), and dry packing types (sealed collection of excreta).

II. Technological Upgrades and Intelligence
In recent years, urban smart public toilet stations have emerged as a new trend. Integrating mobile prefabricated buildings with IoT technology, their main structures adopt lightweight steel or new composite materials, with internal functional modules (such as toilet stalls and management rooms) flexibly configurable based on foot traffic. Smart systems enable functions like facial recognition for paper dispensing, automatic flushing, environmental monitoring (temperature, humidity, air quality), foot traffic statistics, and remote fault alerts. Some products are equipped with solar panels or rainwater harvesting systems to reduce energy consumption. For example, in 2026, prefabricated public toilets using waterless microbial degradation technology eliminate the need for sewage pipelines, requiring only hardened ground for site selection. Construction periods are shortened from three months to one week, with real-time monitoring of foot traffic, energy consumption, and degradation tank activity via 5G IoT, achieving “unmanned and low-carbon” operation and maintenance.

III. Typical Cases and Performance Advantages
Some prefabricated public toilets achieve “three nos” goals: no water flushing (microbial degradation of excreta), no odors (gravity-sensing squat toilets isolate odors), and no pollution (degradation rate exceeding 96%, air quality approaching sterile and odorless conditions). For example, a four-stall mobile toilet produced by Dezhou Hongtu Metal Products Co., Ltd. measures 4 meters in length and 2.3 meters in width, featuring insulated and heat-retaining metal carved exterior walls. The men's toilet is equipped with two stalls, urinals, and a sink, costing less than 20,000 yuan, combining practicality and cost-effectiveness.

IV. Application Scenarios and Value
Mobile toilets are suitable for urban temporary events, scenic spots, transportation hubs, and other scenarios, addressing issues like long construction periods and limited site selection for traditional public toilets. Smart public toilet stations enhance public service efficiency through modular design and intelligent management, promoting the development of urban sanitation facilities toward environmental protection, energy efficiency, and intelligence.
