Suppliers and Contact Information
Haoshitong Pipeline Engineering (Beijing) Co., Ltd. provides rental services, with contact numbers 13611098718, 13521625753, and 010-83406278; Henan Guting Metal Products Co., Ltd. supplies the products, with the contact number 18538158718.

Core Product Features

1. Cost-Effectiveness: Portable toilets do not require large-scale land planning and infrastructure construction. They are mainly assembled, significantly reducing labor and material inputs. They have a high return on investment and can quickly recover costs through rental or placement in high-traffic scenarios (such as scenic spots and event venues).
2. Technical Construction:
   • Water Storage System: It adopts a hierarchical design, with independent supply of flushing water and handwashing water. The water consumption is precisely calculated to adapt to different usage frequencies.
   • Waste Treatment: Solid-liquid separation is achieved through sealed containers and biodegradable materials. Some models are equipped with activated carbon filters to control odor diffusion.
   • Spatial Isolation: Lightweight composite materials are used, balancing structural stability with the need for rapid assembly and disassembly.
3. Material Adaptability:
   • The exterior walls are made of fiberglass (corrosion-resistant) or galvanized steel plates (impact-resistant). The internal pipes are made of polyethylene material (resistant to temperatures as low as -20°C), suitable for the winter climate in Zhangjiakou.
   • The anti-slip floor is made of embossed aluminum plates, with a friction coefficient of ≥0.6 in wet conditions; the joints are treated with silicone sealant to prevent cracking due to temperature changes.

Operating Parameters in Zhangjiakou's Climate

1. Anti-Freezing Design: The water supply pipes are wrapped with ≥30 mm polyurethane insulation material, and the ventilation system activates a low-power warm air circulation device in winter.
2. Anti-Sandstorm Measures: The air inlets and outlets are equipped with washable filters with a pore size of ≤0.5 mm.
3. Power Supply Guarantee: Standard configurations include solar panels and battery packs, which can maintain basic lighting for more than 72 hours on consecutive cloudy days.

Installation and Maintenance Requirements

1. Layout Specifications: Each unit occupies an area of 1.2m×1.2m to 1.5m×1.8m, with a device spacing of 0.8-1.2 meters. The ground flatness error should be ≤5 mm, and the inclination should be ≤1%.
2. Cleaning System:
   • Basic cleaning involves surface disinfection every 4 hours, deep cleaning involves daily waste disposal, and excellent cleaning involves weekly pipe flushing and filter replacement.
   • Disinfectants are selected from quaternary ammonium compounds, which are stable at low temperatures and have low corrosiveness.
   • Solid waste is classified for disposal, and liquid waste must be treated in a three-stage sedimentation tank before discharge, with a suspended solids concentration of ≤50 mg/L.

Environmental Adaptability Improvements
The temperature sensor automatically enhances insulation when the average temperature over three consecutive days is < -15°C; when the usage frequency counter shows an average daily usage of > 80 times, additional backup units are required; the air quality monitor operates continuously.
