Water and Electricity Installation for Environmental Protection Mobile Toilets

The installation of water and electricity for environmental protection mobile toilets requires special attention to power access, equipment wiring, water pipeline connections, and sealing and mold prevention. The specific operations are as follows:

I. Power Installation Specifications

1. On-site Survey and Access Conditions

   • Before installation, evaluate the on-site power supply capacity to ensure that the voltage and current meet the requirements of the water circulation treatment host (usually 220V/50Hz). If there is no power supply on-site, plan the cable laying path in advance and avoid low-lying areas prone to water accumulation to prevent circuit short circuits caused by rainwater immersion.
   • The water circulation host must be independently grounded, with a grounding resistance of ≤4Ω, to avoid the risk of electric leakage.

2. Equipment Wiring and Protection

   • The host should be installed in a well-ventilated and dry location, at least 30cm away from the wall for heat dissipation; the wiring should be protected by PVC pipes or metal hoses to avoid direct exposure to a humid environment.
   • A filter (pore size ≤1mm) should be installed on the water inlet pipeline near the host to prevent impurities from entering the water pump or solenoid valve and causing damage to the circuit components.

II. Water Pipeline Installation Points

1. Inlet Water System Connection

   • When connecting the external water supply pipe to the toilet inlet valve and water storage tank, a double-sealing structure should be adopted: after fixing with a flange ring (thickness ≥10mm), apply neutral weather-resistant glass glue at the joint to ensure no leakage.
   • The inlet-end filter should be cleaned regularly (recommended once a month) to avoid clogging and affecting the water circulation efficiency.

2. Internal Circulation Pipeline Layout

   • Connect the toilet, collection tank, water circulation host, and clean water tank in sequence according to the flow chart. The pipeline should maintain a slope of 3%-5% to avoid water accumulation; use 45° elbows at bends to reduce resistance.
   • The sealing at pipeline openings should be strict: use a thickened flange ring in combination with glass glue, with a glue layer thickness of ≥2mm, to prevent mold growth or odor leakage.

3. Drainage and Maintenance Design

   • The drainage outlet should be flush with the ground, and the pipeline joints should be connected using hot-melt connection or special glue to ensure smoothness and no misalignment; reserve a maintenance space of ≥15cm around the toilet for easy later maintenance of the circuit or cleaning of blockages.

III. General Safety and Acceptance Standards

1. Sealing and Mold Prevention Treatment

   • Apply two coats of neutral weather-resistant glass glue at the joint between the toilet base and the ground, and manually smooth the wall joints; the length of the PVC extension pipe should not exceed 1.5 meters (≤3 sections) to reduce joints and lower the risk of water leakage.

2. Safety Testing and Maintenance

   • After installation, conduct a power-on test: check whether the leakage protector can cut off the power supply within 0.1 seconds (simulate a leakage scenario); the water pipeline should be pressurized to 0.6MPa and maintained for 30 minutes without leakage.
   • Check the status of the filter and leakage protector monthly, and clean the internal dirt of the water circulation host quarterly to ensure the stable operation of the system.

By following standardized operations and regular maintenance, the water and electricity system of environmental protection mobile toilets can be guaranteed to operate efficiently and safely, extending the service life of the equipment.
