Shiyan Environmental Protection Portable Toilet

The Shiyan environmental protection portable toilet covers rental services, production technology features, and functional principles. Here is a detailed introduction:

Rental Services
Shiyan offers rental services for environmental protection portable toilets, covering scenarios such as marathons, concerts, music festivals, and construction sites. There is an in-stock supply in Zhangwan District, supporting nationwide chain rentals. Prices are tiered based on the order quantity: 370 yuan for orders of 1 unit, 298 yuan for orders of 5 units, and 287 yuan for orders of 10 units, with nationwide free shipping. The rental service is flexible and can meet short-term or long-term needs.

Production Technology Features

1. Structural Design: Optimized stress distribution in the bottom frame is tailored to Shiyan's terrain (such as slopes and non-hardened ground). Outdoor square models are equipped with additional ballast compartments or anchor bolt预留 holes (reserved holes for anchor bolts), while construction site models have reserved lifting points for easy transportation, ensuring both stability and portability.
2. Material Selection: The outer shell is molded in one piece from high-pressure polyethylene (HDPE), with the addition of UV inhibitors (the proportion adjusted according to sunlight intensity). Fiberglass (FRP) sandwich panels use pre-embedded sealing strip technology. The floor is replaced with engineered plastic flooring featuring drainage channels and embedded anti-slip particles, balancing corrosion resistance and lightweight design.
3. Sewage Disposal System: There are two types: "direct discharge" and "circulating." Direct discharge relies on septic tanks or sewage trucks for extraction, with the tank volume calculated based on usage frequency. The circulating type employs microbial degradation or solid-liquid separation technology. In Shiyan's cold winters, biological treatment requires the installation of insulation layers and electric tracing devices. Some equipment uses air-water mixed flushing technology.
4. Scenario-Specific Functions: Mining areas are equipped with explosion-proof lighting, anti-static flooring, and dust filtration nets. Scenic spots focus on外观设计 (external design), balancing practicality and aesthetics.

Functional Principles

1. Fluid Transfer and Storage: Sewage pipes maintain a pressure gradient to ensure the smooth transfer of solid-liquid mixtures to the storage tank. The tank bottom is inclined, and the inner walls use low-surface-energy materials. Anti-tipping designs and liquid level balancing devices adapt to terrain undulations.
2. Air Pressure Balance and Odor Control: A negative pressure ventilation system, combined with a one-way exhaust valve at the top of the sewage storage tank, and some equipment is equipped with UV decomposition devices to suppress odor diffusion.
3. Gravity Water Supply: The flushing system relies on gravity water supply, with the water tank liquid level height matching the pipe hydraulic radius. In Shiyan's cold winters, large-orifice flush valves are used, and the water tank design avoids vortex phenomena to ensure flushing efficiency.
4. Solid-Liquid Separation and Volume Optimization: The inner walls of the tank are coated with superhydrophobic coatings, and some equipment uses a spiral baffle design to reduce residue and improve storage space utilization.
