Zhangjiakou Mobile Toilet
The Zhangjiakou mobile toilet is a sanitation facility designed based on environmental adaptability and resource efficiency, featuring multiple functional characteristics to meet the needs of different scenarios.
Design, Construction, and Materials
The core construction of the mobile toilet includes a water storage system, a waste treatment unit, and a space isolation module. The water storage system is designed in a tiered manner, with separate water supplies for flushing and handwashing. The waste treatment unit achieves solid-liquid separation through sealed containers and biodegradable materials, with some units equipped with activated carbon filtration devices to control odors. The exterior wall panels are mostly made of fiberglass-reinforced plastic or galvanized steel sheets, with the former being corrosion-resistant and the latter impact-resistant. The internal piping system uses polyethylene material, which can withstand temperatures as low as minus twenty degrees Celsius, making it suitable for the winter climate in Zhangjiakou. The non-slip floor is made of embossed aluminum sheets, with a friction coefficient exceeding 0.6 when wet. The seams are treated with silicone sealant for a second time to prevent deformation and cracking.
Operating Parameters and Installation
The equipment needs to be equipped with freeze-proof water supply pipelines, wrapped with a layer of polyurethane insulation material no less than 30 millimeters thick. The ventilation system adopts a bidirectional air exchange mode, with natural convection in summer and the activation of a low-power warm air circulation device in winter. Air inlets and outlets are fitted with washable filters with a pore size no larger than 0.5 millimeters to cope with sandstorms. The standard power supply configuration includes solar panels and battery packs, which can maintain basic lighting for more than 72 hours on consecutive cloudy days. Each unit occupies an area ranging from 1.2 meters by 1.2 meters to 1.5 meters by 1.8 meters, and can be combined according to the density of users. The layout options include linear (suitable for narrow areas) and circular (optimizing pedestrian flow efficiency). The distance between equipment units ranges from 0.8 meters to 1.2 meters, with a ground foundation flatness error not exceeding 5 millimeters and a slope controlled within 1%.
Cleaning, Maintenance, and Environmental Adaptation
Daily cleaning is divided into three levels: basic cleaning involves surface disinfection every 4 hours, deep cleaning involves handling internal waste daily, and excellent cleaning involves flushing pipelines and replacing filters weekly. Disinfectants are selected from quaternary ammonium compounds, which have strong low-temperature activity and low corrosiveness. Solid waste is classified and treated, with biodegradable materials sent to composting facilities and non-biodegradable materials disposed of according to local regulations. Liquid waste needs to undergo three-stage treatment in a sedimentation tank before discharge, reducing the suspended solids concentration to below 50 milligrams per liter. Temperature sensors monitor the internal temperature, and when the average temperature over three consecutive days is below minus fifteen degrees Celsius, the insulation is automatically enhanced. Usage frequency counters optimize the configuration, and when a single unit is used more than 80 times a day on average, additional backup units are added. Air quality monitors continuously monitor the environment.
