Zhoushan Mobile Toilet Installation

The installation of mobile toilets in Zhoushan requires comprehensive consideration of technical configuration, service selection, and operational specifications to ensure stable equipment operation and a good user experience.

1. Technical Configuration: Rational Construction of Modular Systems

Mobile toilets are integrated systems comprising three core modules:

1. Toilet Unit Module: Choose between squat or sit-type toilets based on the usage scenario, ensuring the interior space meets ergonomic standards (e.g., a net width of ≥0.8 meters) to avoid discomfort due to cramped conditions.
2. Waste Treatment and Storage Module:
   • For circulating water-flush types, equip with a biodegradation device that uses microorganisms to decompose waste and recycle water, suitable for long-term use scenarios.
   • For bagging types, regularly replace the fecal storage bags, reserve operational space, and ensure airtightness to prevent odor leakage.
   • For direct-discharge types, connect to the municipal drainage system, confirming the site's drainage conditions in advance.
3. Auxiliary Support Module:
   • Water Supply Module: If using a water-flush type, connect to the municipal water supply or equip with a water tank (recommended capacity of ≥500L/day).
   • Power Supply Module: Lighting, ventilation, and other equipment require a stable power source, which can be connected to the municipal power grid or use a mobile power supply (power ≥1kW).
   • Structural Stability Module: Choose a fixation method based on ground conditions (e.g., mud or hard ground), such as expansion bolt fixation or weight block reinforcement, ensuring a wind resistance rating of ≥8.

2. Service Selection: Key Elements of Professional Rental Companies

1. Quantity Configuration: Calculate based on event scale and site conditions, recommending one standard toilet per 50 people, with a 20% redundancy during peak times.
2. Installation Plan: Regular service providers offer free on-site surveys and design plans based on terrain:
   • For lawns, lay anti-settlement foundations.
   • For muddy ground, harden the surface or use deep pile fixation.
   • For hard ground, confirm load-bearing capacity (recommended ≥300kg/㎡).
3. Supporting Services:
   • Water and electricity access: Some service providers offer mobile power and water tank rentals.
   • Cleaning and maintenance: At least one daily collection and disinfection to prevent waste accumulation.
   • Emergency response: 24-hour fault repair services to ensure equipment availability of ≥95%.

3. Operational Specifications: Installation Steps and Precautions

1. Basic Installation:
   • Use an electric drill (equipped with a 4.2mm drill bit) to drill holes in the ground, with a depth of ≥50mm.
   • Insert expansion bolts and fix the base frame, ensuring a horizontal error of ≤2mm.
   • When assembling wall panels, insert the panels into the slots and align them, drill holes, insert rivets, and secure them with a rivet gun.
2. Module Connection:
   • Seal the connection between the waste treatment module and the toilet unit using silicone gaskets to prevent leakage.
   • Install check valves in the water supply pipes to prevent backflow of sewage.
   • Ground the electrical circuits to prevent electric shock risks.
3. Acceptance Criteria:
   • Flush pressure of ≥0.15MPa, with smooth drainage.
   • Ventilation system air exchange rate of ≥8 times/hour, with no residual odor.
   • Structural stability test: Simulate a wind force of 5, with no shaking or displacement of the equipment.

Through the synergy of technical configuration, service selection, and operational specifications, efficient installation and long-term stable operation of mobile toilets in Zhoushan can be achieved.
