How to Install Mobile Toilets in Fish Ponds

The installation of mobile toilets in fish ponds should be designed according to their intended use: for aquaculture scenarios, a 'fish toilet' (ancillary pool) should be constructed, while for human use, modular mobile toilets should be deployed.

I. Aquaculture Scenario: Design of Fish Toilet (Ancillary Pool)

1. Structure and Function
   The fish toilet is a core facility in the factory-based internal circulation eel farming system, achieving solid-liquid separation of feces through an ancillary pool. Its structure is divided into collection area, buffer area, and clean water area, with a ratio of 4:4:2. The bottom is interconnected, but the middle and upper parts allow water to pass through. Eel feces flow into the collection area through a 1% slope at the bottom of the breeding pool and are discharged to the external circulation system at regular intervals through a plug-in pipe or automatic control system. The buffer and clean water areas further separate liquids from solids, reducing water pollution.

2. Construction Points

   • Location and Dimensions: The ancillary pool should be built on one side of the eel pool, with a width of 0.9m to 1.0m and a long side of at least 6m (favorable for sedimentation). The bottom slope should be 2.5% to 3%, with a drainage outlet size of 1.0m × 1.0m and an internal circulation pipe diameter of 160mm.
   • Materials and Equipment: The pool body should be compacted with red soil or plastered with cement to ensure smoothness without bumps. The drainage system should use plug-in pipes or automatic control devices with a diameter of 200mm to 250mm to prevent the pool water from being emptied. The eel drainage pipe should be designed with an inner insert to prevent eel escape.

II. Human Use Scenario: Modular Mobile Toilets

1. Functional Configuration
   Mobile toilets for human use should be equipped with sanitary ware, water tanks, deodorization systems, etc. The recommended TLXT modular system supports rapid deployment (a team of 4 can install 10 units in 2 hours) without the need for ground hardening. Core configurations include a biodegradable toilet (reducing sewage discharge), an exhaust fan (maintaining air circulation), and a freeze-proof design (usable at -15°C), adapting to outdoor environments.

2. Customized Services
   Additional facilities such as shower rooms and baby care rooms can be added according to needs, or the size can be adjusted (single room/double room/family suite). For example, a fish pond in a scenic area can choose a double room + shower room combination, while a fish pond on a construction site can prioritize a single room + freeze-proof design.

III. Key Differences and Applicable Scenarios

1. Functional Differences
   The fish toilet is specifically designed for aquaculture, with its core function being solid-liquid separation and drainage, without the need for sanitary ware. In contrast, mobile toilets for human use need to meet needs such as defecation and cleaning, requiring a complete sanitary system.
2. Application Scenarios
   The fish toilet is suitable for factory-based breeding fish ponds (such as eel ponds), while mobile toilets for human use are suitable for scenarios where staff or tourists use them around fish ponds (such as scenic areas and construction sites).

Summary: For pure aquaculture scenarios, a fish toilet should be constructed according to internal circulation eel farming technology to achieve feces separation and drainage. If human use needs to be considered, modular mobile toilets can be deployed around the fish pond, balancing environmental protection and convenience.
