Hejian Environmental Protection Mobile Toilet
The Hejian environmental protection mobile toilet is an eco-friendly mobile sanitation facility designed for the needs of northern rural areas and multiple scenarios. It features freeze resistance, load-bearing capacity, strong adaptability, and forms a closed loop for fecal waste treatment, with diverse technical solutions and wide application scenarios.
Industrial Background and R&D Logic
Relying on the sanitation equipment manufacturing cluster in Hejian City, Hebei Jingmei Sanitation Equipment Co., Ltd. is rooted locally, with engineers conducting in-depth research into the real working conditions of northern rural areas to design targeted products. For example, the chassis adopts a double-layer hot-dip galvanized steel frame with column wall thickness of 3.0 millimeters, capable of withstanding continuous snow loads and accidental collisions from agricultural tricycles; below the squatting position, there is a 1.2-cubic-meter detachable polypropylene fecal storage tank with an embedded insulation layer, which can maintain the liquid flowability of fecal waste at -15°C to prevent freezing and blockage; the wall adopts a 75-millimeter rock wool sandwich panel, covered with 0.5-millimeter galvanized steel sheets on both sides and treated with electrostatic spraying, with an anti-ultraviolet aging cycle exceeding 8 years, adapting to the severe cold and strong sunlight environment in northern China.
Eco-Friendly Closed Loop and Resource Utilization
The bottom of the fecal storage tank is equipped with a standard flange interface, which can be directly connected to the hose of a sewage suction truck for easy fecal waste transfer; the tank has a built-in biological agent slow-release chamber that continuously decomposes organic matter during storage, reducing ammonia nitrogen concentration and odor intensity; it is equipped with a biodegradable inner liner bag, which is transferred to the township centralized treatment station along with the fecal waste when replaced. Some pilot villages link the mobile toilet with the village-level biogas digester, and after preliminary fermentation, the fecal liquid enters the anaerobic tank, increasing the gas production efficiency by 22%, achieving resource utilization of fecal waste.
Technical Solutions and Water-Saving Design
The product covers three technical solutions: waterless flushing, foam sealing, and water flushing:
- Waterless flushing: No need to connect to water supply and drainage pipes, relying on the fecal storage tank and biodegradation technology, suitable for water-scarce areas;
- Water flushing: Requires connection to water supply and drainage pipes, adopting a rainwater collection and filtration system and hand-washing water secondary flushing technology, reducing water consumption per flush by 40% compared to traditional toilets;
- Foam sealing: Covers the surface of fecal waste with foaming liquid to reduce odor and water consumption for flushing.
Application Scenarios and Price Range
The product line covers细分场景 (sub-scenarios) such as construction site temporary toilets, scenic area garden toilets, and vehicle-mounted toilets, and also provides mobile toilet rental services for large-scale events such as marathons and concerts. In terms of price, some products are priced at 8,500 yuan each, while products produced in Dezhou, Shandong, are priced between 5,000 and 5,500 yuan, with differences possibly related to materials, technical configurations, or transportation costs.
The Hejian environmental protection mobile toilet has become an important solution for upgrading sanitation facilities in northern rural areas and ensuring temporary events through structural reinforcement, an eco-friendly closed loop, and multi-scenario adaptability.
