Suixian Mobile Toilet Dry-Wet Separation

Admin October 11, 2026

The dry-wet separation design of mobile toilets in Suixian is achieved through patented technology, primarily addressing issues such as delayed waste treatment, environmental pollution, and high maintenance costs in traditional mobile toilets. The core principles and structural features are as follows:

Core Mechanism of Dry-Wet Separation

The core of dry-wet separation lies in treating feces and urine separately. Feces automatically fall into the waste treatment tank through a toilet hole baffle linkage mechanism, preventing mixing with urine. This mechanism, designed with mechanical linkage, ensures the baffle automatically resets after use, preventing waste overflow or residue. Urine flows through an independent pipe into a urine collection tank, achieving initial solid-liquid separation. This design reduces odor and decay issues caused by waste mixing, facilitating subsequent treatment.

Feces Treatment Technology

Feces falling into the waste treatment tank are rapidly decomposed using biodegradation technology. Specific biodegrading bacteria are added to the tank, which quickly break down organic matter, converting feces into harmless substances (such as carbon dioxide and water) and significantly shortening the treatment cycle. The biodegradation process requires no additional chemicals, making it environmentally friendly and cost-effective. The volume of residual waste after treatment is greatly reduced, facilitating regular cleaning or further resource utilization (such as composting).

Urine Purification System

After being collected in the urine collection tank, urine is directed into a multi-stage treatment system for purification. A typical process includes:

  1. MBR Membrane Reactor: Using membrane separation technology to retain suspended solids, bacteria, and some organic matter in the urine, achieving deep solid-liquid separation and stable effluent quality.
  2. Activated Carbon Filtration: Utilizing the adsorption properties of activated carbon to further remove odors, pigments, and trace organic pollutants from the urine, enhancing water clarity.
    The purified urine meets discharge standards and can be directly discharged into municipal sewage networks or used for green irrigation through outlet pipes, achieving water resource recycling.

Advantages of Modular Structure

This mobile toilet adopts a modular design, with components such as the waste treatment tank, urine collection tank, and purification system independently detachable and replaceable. This design facilitates rapid maintenance and upgrades, such as replacing biodegrading bacteria or cleaning filtration membranes without requiring complete disassembly, significantly reducing labor costs. Additionally, the modular structure enhances the toilet's adaptability and scalability, allowing flexible adjustment of treatment capacity or addition/removal of functional modules based on usage scenarios.

Environmental and Economic Benefits

The dry-wet separation design effectively reduces odor diffusion and environmental pollution issues caused by waste mixing in traditional mobile toilets, improving public health environments. Biodegradation and multi-stage purification technologies reduce reliance on chemicals, minimizing secondary pollution risks. Furthermore, the modular maintenance model extends equipment lifespan, reducing overall maintenance costs by approximately 30%-50% compared to traditional toilets, offering significant economic and environmental advantages.
