Baotou Construction Site Portable Toilet

The Baotou construction site portable toilet is characterized by integrated technology, durable materials, and modular installation, meeting the temporary needs of construction sites. Prices start at 7500 yuan, and customization is supported.

I. Excreta Treatment System: Three Technical Paths for Different Scenarios

The core technology of the Baotou construction site portable toilet lies in the integration and optimization of the excreta treatment system, which is mainly divided into three categories:

1. Water-flushing System: The water tank and sewage tank are integrated inside the toilet body, equipped with a large-capacity freshwater tank (usually exceeding 200L) and a sewage collection tank. High-pressure pneumatic or electric water pumps are used to reduce the amount of water used per flush (approximately 0.5-1L/flush), making it suitable for construction sites with sufficient water sources and convenient sewage discharge conditions.
2. Foam Sealing System: A foam layer containing special surfactants is applied to the surface of the toilet bowl through a foam generator, serving to lubricate, isolate odors, and reduce water consumption. The core of this system is the coordination between the foam liquid and the liquid level control system. However, in Baotou's cold winters, the mobility of the foam liquid needs to be addressed, typically by using low-temperature formulations or installing heating tapes.
3. Microbial Degradation System: Inside, there is a bioreactor with specially cultivated microbial flora that decomposes excreta into water vapor, carbon dioxide, and a small amount of inorganic salt residues under aerobic conditions. This system requires a heating device (to maintain a temperature of 20-40°C) and a stirring system, and it needs continuous power supply during operation. It has high technical requirements for maintenance personnel and is suitable for construction sites without sewage pipes and with suitable ambient temperatures.

II. Materials and Structure: Balancing Durability and Installation Efficiency

1. Wall Structure: Mostly made of fiberglass-reinforced plastic (FRP) or stainless steel. FRP is molded and has the characteristics of light weight (approximately 50-80kg/㎡) and good thermal insulation (thermal conductivity ≤ 0.22W/m·K), making it suitable for standardized mass production. Stainless steel has high structural strength (yield strength ≥ 205MPa) and strong corrosion resistance, making it suitable for public environments or scenarios where chemical disinfectants are frequently used.
2. Load-bearing Framework: The main load-bearing components are made of cold-formed steel sections, with framework nodes connected by bolts. The exterior is wrapped with FRP or galvanized steel sheets, ensuring structural stability and facilitating modular installation.
3. Ventilation and Deodorization System: A combination of top exhaust and bottom intake is used to form a directional airflow, which is treated and discharged through activated carbon filtration or ultraviolet light deodorization equipment. The exhaust fan requires a static pressure of ≥300Pa and an air volume of ≥500m³/h. The filter material replacement cycle is usually 3-6 months, and it should be clearly indicated by the manufacturer.

III. Customization and Pricing: Flexibly Adapting to Construction Site Needs

Taking Cangzhou Hengtai Sanitation Equipment Co., Ltd. as an example, the price of its Baotou construction site temporary portable toilets starts at 7500 yuan, supporting batch orders from as few as one unit. Models include htcs-032, htcs-259, etc. The products can be customized, with material options including color steel plates, metal carved plates, anti-corrosion wood, and aluminum-plastic plates; sewage discharge methods covering water flushing, packing, foaming, and microbial degradation; and applicable scenarios including municipal, parks, scenic spots, and construction sites. The production process follows a modular principle, with all components prefabricated in the factory, and on-site installation usually taking no more than 4 hours, significantly shortening the construction period.
