Mobile Toilet Not Flushing Feces

There can be multiple reasons why a mobile toilet fails to flush feces, and targeted troubleshooting and handling are required based on the type of toilet. Here is a detailed analysis:

Water-flush and non-water-flush suction-type mobile public toilets: The sewage tank of such toilets has a limited capacity. When the number of users reaches the specified upper limit, if suction operations are not carried out in a timely manner, the sewage tank will overflow and affect the normal operation of the flushing system, resulting in poor flushing or even an inability to flush. The handling method is to promptly contact professionals to suction the sewage tank, ensure its capacity is within the normal range, and restore the flushing function.

Recirculating water-flush mobile public toilets: This type of toilet is equipped with an intermittent aerobic and anaerobic treatment device for fecal sewage, which is crucial for maintaining normal toilet flushing. If the device malfunctions, such as pipe blockages or equipment aging and damage, it will directly affect the flushing effect. The handling method is to inspect each component of the treatment device, check for blockages or damage, promptly clean blockages or replace damaged components to ensure the normal operation of the device.

Dry-packing mobile public toilets: These toilets do not have a water-flushing device. Feces are collected by biodegradable plastic bags, and normally, there are no flushing issues. If there is a problem with not flushing feces, it is likely that the plastic bag replacement mechanism has malfunctioned, preventing the plastic bags from being replaced normally to collect feces. The handling method is to inspect the plastic bag replacement mechanism, check for issues such as jams or damage, promptly repair or replace relevant components, and replace with new plastic bags.

Foam-sealing mobile public toilets: They use foam generated by a foaming liquid mixture instead of toilet flushing. If the foaming system malfunctions, such as insufficient foaming liquid or damage to the foaming device, it will not be able to generate enough foam, leading to an inability to flush. The handling method is to inspect the foaming device, replenish the foaming liquid, repair or replace damaged foaming device components to ensure the normal operation of the foaming system.

Microbial mobile public toilets: Feces enter a solid-liquid separation device through an automatically opening toilet bowl. If this device malfunctions, such as incomplete separation or blockages, it will affect the subsequent flushing and treatment processes. The handling method is to inspect the solid-liquid separation device and the microbial treatment system, clean blockages, repair faulty components, and ensure the normal operation of the entire system.
