Mobile Toilet - Trough Type

The trough-type toilet in mobile toilets is a form of public toilet that uses continuous or segmented troughs to collect excreta and discharges it through a centralized flushing system. Its core features, structural composition, and sanitation management points are as follows:

I. Core Features and Applicable Scenarios Trough-type toilets collect urine and feces through continuous or segmented troughs arranged along walls or partitions, with users completing excretion in a squatting position. Their design features include high space utilization (a single trough can serve multiple squatting positions), controllable cost (simple structure and low material cost), and convenient centralized treatment (cleaning staff can flush the troughs uniformly). Such facilities are commonly found in old public toilets, stations, markets, factories, and other places with a high density of people and a need for rapid turnover, especially suitable for areas sensitive to construction costs and with high usage frequencies.

II. Structural Composition and Flushing Methods

1. Basic Structure: It consists of a sewage-bearing trough (the core sewage discharge component), squatting position pedals or platforms (providing standing support), flushing pipelines (transporting flushing water), floor drains (draining accumulated water on the floor), traps (preventing odor backflow), and a main sewage discharge pipe (connecting to the municipal sewer network or septic tank).
2. Flushing Modes: These include front-end centralized flushing (injecting water from the front end of the trough for a one-time flush), overhead spraying (uniformly covering the trough through nozzles), segmented flushing (flushing independent trough segments separately), and sensor-based flushing (automatically triggering flushing through sensors). Among them, sensor-based flushing can reduce sanitation hazards caused by manual operation.

III. Sanitation Hazards and Prevention and Control Points The sanitation performance of trough-type toilets is affected by multiple factors:

1. Drainage Slope: The trough needs to maintain a slope of ≥2% to ensure that excreta is smoothly discharged into the main pipe. Insufficient slope can easily lead to residue.
2. Flushing Intensity: Insufficient flushing volume or low pressure can cause excreta to adhere. It is recommended that the single flushing volume be ≥3L per meter of trough.
3. Partition Design: Solid partitions with a height of ≥1.8 meters should be installed between squatting positions to reduce the risk of splashing contamination.
4. Daily Cleaning: A comprehensive flush should be carried out at least twice a day, and special tools should be used to clean the edges of the trough and floor drains to avoid cross-infection caused by the cross-use of cleaning tools.
5. Ventilation Management: Install exhaust fans or natural ventilation openings to maintain air circulation and reduce odor concentration.

By optimizing the above design parameters and strictly implementing cleaning specifications, the sanitation level of trough-type toilets can be significantly improved to meet the basic usage needs of public places.
