How to Maintain Hygiene in Mobile Toilets

Maintaining hygiene in mobile toilets requires comprehensive management in terms of daily cleaning, sewage system maintenance, special environmental maintenance, and equipment inspection. Specific measures are as follows:

I. Daily Cleaning (Must-Do Every Day)

1. Surface Cleaning: Use a neutral cleaner to wipe down high-contact areas such as the inner and outer walls, door handles, and handrails. Avoid using strong acid or alkaline cleaners to prevent corrosion of the material surface and ensure no stains remain.
2. Squat Toilet Cleaning: Use a long-handled brush with toilet cleaner to thoroughly scrub the inner walls of the toilet bowl, focusing on removing urine scale and fecal residue. Strictly prohibit disposing of items such as sanitary napkins, cigarette butts, and plastic bags into the toilet bowl, as these can easily clog the pipes and increase maintenance costs.
3. Floor Cleaning: Use a dry mop to remove moisture from the floor, keeping it dry to prevent slip and fall accidents. If using a water-flush toilet, promptly clean up any splashed water to avoid bacterial growth.

II. Sewage System Maintenance

1. Storage-Type Toilets: Check the liquid level in the bottom black water tank daily. The liquid level must not exceed two-thirds of the tank's capacity. Before overflow occurs, contact a fecal suction truck for removal. Monthly, add a septic agent (biological enzyme or chemical agent) to the black water tank to accelerate solid decomposition, suppress odors, and prevent clogging.
2. Direct-Discharge Toilets: Regularly inspect the sewage pipes for blockages and clean any debris such as leaves and sand accumulated at the pipe openings to ensure that sewage can be directly discharged into the municipal sewer network or septic tank.

III. Special Maintenance in Northern Regions (November-March)

1. Winter Freeze Prevention: At night or during long periods of disuse, it is essential to drain all water from the water tank and pipes. If continuous use is required, activate the electric tracing tape or install insulation cotton to prevent water pipes from freezing and cracking, which could lead to leaks.
2. Wind Resistance Reinforcement: Check whether the bottom fixing bolts or wind-resistant guy wires are loose and tighten them promptly to avoid the risk of overturning in strong winds.
3. Metal Part Rust Prevention: Regularly inspect metal components such as hinges and locks. If rust is found, immediately apply lubricating oil or anti-rust paint to extend the service life of the equipment.

IV. Equipment Inspection and Consumable Replenishment

1. Water and Electricity Function Testing: Daily check whether the lighting, exhaust fans, and flush valves are functioning properly. Promptly repair any faults to avoid affecting the user experience.
2. Consumable Replenishment: Timely replace hand soap, toilet paper, and foaming liquid (specific to foam-sealing toilets) to meet user needs. If using a water-saving flush device, regularly check the stability of the water pressure to reduce water waste.

In addition, the sewage system design of mobile toilets must comply with the 'Urban Public Toilet Design Standard' (CJJ14-2016) to ensure smooth and environmentally friendly sewage discharge. Regular cleaning of the septic tank can prevent blockages and odors, while optimizing the flushing method (such as foam-sealing technology) can further reduce the difficulty of hygiene maintenance.
