Yichang Environmental Protection Mobile Toilet

The Yichang environmental protection mobile toilet is an independently operating facility based on a 'non-pipeline excreta treatment system'. It is widely used in large-scale events, construction sites, and temporary gathering places, featuring water conservation, environmental protection, and strong climate adaptability.

Technical Principles and Operation Logic

The core of the Yichang environmental protection mobile toilet is a closed-loop system of 'containerized storage + chemical-physical treatment', operating independently of traditional pipelines. Excreta is stored in closed sewage containers rather than undergoing biochemical degradation, reducing reliance on the external environment. For example, a standard single sewage container has a volume of approximately 1.5 to 2 cubic meters and can last 3 to 4 days without emptying when used by 150 people per day. A liquid level sensor in the container triggers an alert when the volume reaches 80%, prompting the dispatch of a suction truck for external treatment.

Water Conservation and Odor Control Technologies

1. Foam Sealing Technology: Foam is generated by a foaming agent to fill the toilet pipes, lubricating while blocking odor from escaping. This technology uses only one-tenth of the water used in traditional flushing, with each flush consuming 0.1 to 0.2 liters of water, significantly slowing the filling of the sewage container. However, the foaming agent needs to be added regularly and its proportion adjusted.
2. Packaging Technology: A mechanical device seals excreta into biodegradable plastic bags, which are independently packaged and fall into a collection box, requiring no external water source and suitable for water-scarce environments. However, the cost of consumables is slightly higher than that of foam sealing, and maintenance only requires replacing the consumable rolls.

Climate Adaptability Design

1. Winter Anti-freezing: Low temperatures in Yichang in winter may cause pipeline freezing. The equipment is equipped with an electric tracing system, with self-limiting heating cables wrapped around the pipeline walls. When the temperature drops below 5℃, the system automatically powers on, maintaining the pipeline temperature above 10℃.
2. Summer Deodorization: High temperatures accelerate microbial activity, producing ammonia and hydrogen sulfide. A two-stage approach is adopted: first, biological enzyme preparations are added to decompose organic matter and inhibit gas production; second, top ventilation fans and activated carbon filtration devices are used to adsorb and discharge gases.
