Large-Scale Mobile Ecological Toilet Design
The design of large-scale mobile ecological toilets requires comprehensive consideration from multiple aspects, including structure, functional layout, sewage treatment and ecological technology, and design principles.
In terms of structure: A steel-frame cement composite structure can be selected. It has excellent thermal insulation performance, a service life of over 20 years, and can adapt to various environments. Some steel-frame structures can even be used in environments as cold as minus 28°C. There are also designs that use galvanized steel-frame structures. For example, a mobile toilet customized by a Beijing customer, covering an area of 18 square meters with 6 squatting positions, uses a galvanized steel-frame structure throughout and features a double-roof design, enhancing the structural stability and practicality.
Regarding functional layout: Some designs place hand-washing sinks on both sides with an open hand-washing area in the middle, and the interior is renovated in a home-like style. This layout can fully utilize space, improve space utilization efficiency, and provide users with a more comfortable and convenient experience.
From the perspective of sewage treatment and ecological technology: Ecological public toilets are based on solid-liquid separation technology and achieve harmless treatment of excrement through microbial decomposition. During initial operation, 70 - 80 kilograms of water need to be injected at once to maintain microbial activity. Subsequently, they have characteristics such as water conservation, mobility, and waterless flushing. Modern technology uses microbial communities to decompose feces into carbon dioxide, water, and organic fertilizer. Some models are also equipped with intelligent temperature control systems, with operating temperatures exceeding 60°C, providing both sterilization and disinfection functions. In addition, 5G and Internet of Things technologies are applied to enable remote monitoring, facilitating managers to promptly understand the toilet's operating status.
In terms of design principles: Principles such as mobility and convenience, economy and durability; environmental protection and ecology, beneficial to the environment; improving efficiency and promoting humanity should be followed. The overall structure should be lightweight, using lightweight and durable materials as much as possible, while being sturdy to ensure safety during use. The height and width of the toilet should be controlled to facilitate movement and installation. The mobile device should be complete and reasonable to ensure that the toilet can be easily and quickly moved to the designated location.
