Shitan Town Mobile Toilet

The toilet renovation work currently being promoted in Shitan Town mainly adopts the 'four-compartment septic tank' technology, with no explicit mention of mobile toilet information. Here is a detailed introduction to the toilet renovation technology in Shitan Town:

Principle of the 'Four-Compartment Septic Tank' Technology
This technology is an upgrade from the traditional three-compartment septic tank, forming a four-stage treatment process by adding an artificial small wetland:

1. Interception and Sedimentation: After feces enter the first compartment of the septic tank, solid substances are intercepted and sedimented, achieving initial solid-liquid separation.
2. Fermentation and Decomposition: The second and third compartments further decompose organic matter through anaerobic fermentation, killing parasite eggs and pathogenic microorganisms, and reducing pollutant concentrations.
3. Adsorption and Purification: The fourth compartment, an artificial small wetland, is planted with plants with well-developed root systems such as canna lilies. Using plant adsorption and microbial degradation, it further removes nutrients such as nitrogen and phosphorus, as well as residual pollutants, while eliminating odors.
4. Resource Utilization: The treated fecal liquid is odorless and free of fly larvae, and can be directly used for irrigating vegetables or farmland, achieving ecological recycling of feces.

Toilet Renovation Goals and Implementation Scope
Shitan Town plans to complete the toilet renovation tasks in two key project villages, Zhongxin Village and Liejiaqiao Village, by the end of August, constructing a total of 440 'four-compartment septic tanks'. This technology is suitable for rural decentralized sewage treatment scenarios, especially in areas lacking centralized sewage pipe networks, and can significantly improve rural living environment and sanitation conditions.

Supplementary Explanation Regarding Mobile Toilets
Currently, publicly available information does not cover the purchase price, rental fees, or specific models of mobile toilets in Shitan Town. If you need information about mobile toilets, it is recommended to obtain it through the following channels:

1. Contact the Agricultural and Rural Affairs Office or Sanitation Department of Shitan Town to inquire about any mobile toilet deployment plans;
2. Check announcements on the local government procurement platform to obtain equipment bidding information;
3. Refer to market prices for mobile toilets in surrounding areas. The price of a common single mobile toilet is approximately in the range of 5,000 to 20,000 yuan, and rental fees vary greatly depending on the duration of use and functional configurations.

Summary of Technological Advantages
The 'four-compartment septic tank' achieves harmless and resource-based treatment of feces through ecological treatment, combining environmental and economic benefits, and meeting the technological requirements of the rural toilet revolution. Its core value lies in its low cost, ease of maintenance, and ability to improve soil fertility, but it is necessary to regularly clean the septic tank and manage the growth of wetland plants.
