Suqian Circulating Water Flush Mobile Toilet
Suqian has the potential conditions for applying circulating water flush mobile toilets, but there have been no clearly reported large-scale examples yet. The implementation of the technology needs to be further advanced in combination with local needs.
High Technical Feasibility, Aligned with Resource Utilization Goals
Circulating water flush ecological toilets achieve water resource recycling through biological treatment or membrane separation technology, which is highly consistent with the goal of "fecal waste resource utilization" emphasized in Suqian's "toilet revolution". For example, biological treatment toilets use electrocatalytic reactions to convert feces and urine into carbon dioxide and water. The treated clean water can be reused for toilet flushing or landscaping, and they rely on solar power, making them suitable for scenarios without external power supply. Membrane separation toilets, on the other hand, use membrane technology to separate the supernatant of feces and urine to produce clean water, and ferment the feces to produce organic fertilizer, achieving comprehensive resource utilization of fecal waste. Such technologies have been applied in many places across the country and have a relatively high level of technical maturity.
Suqian's Toilet Renovation Practices Provide a Practical Basis
Suqian has explored resource utilization models in its toilet renovation work, providing experience for the implementation of circulating water flush toilets. For example, Sangxu Town has combined fecal waste with the agricultural industry by having large-scale farmers absorb it, having centralized treatment centers absorb it through agreements, and having villagers independently absorb liquid fertilizer, promoting green agricultural development. Such models are consistent with the goal of "fecal waste resource utilization" of circulating water flush toilets, indicating that the local area has the industrial connection conditions for the implementation of the technology, and the management model of "both supervision and maintenance" can provide a reference for subsequent maintenance.
Market Supply Capacity Supports Technology Implementation
Enterprises in surrounding areas can provide circulating water ecological toilet products and personalized design services. For example, Changzhou Runlong Environmental Protection Technology Co., Ltd. and other enterprises produce circulating water ecological toilets of models such as RL-18 and support the customization of technical solutions according to scenario requirements. Enterprises in Suqian or its surrounding areas may have similar technical supply capabilities. Although specific supplier information needs to be further verified, the market supply conditions have been initially met.
Implementation Suggestions: Prioritize Suitable Technologies and Strengthen Subsequent Maintenance
If circulating water flush mobile toilets need to be promoted in Suqian, it is recommended to combine local agricultural industry needs and prioritize the selection of biological treatment or membrane separation technologies to achieve the dual goals of fecal waste resource utilization and water resource recycling. At the same time, referring to the model of "both supervision and maintenance" in Sangxu Town, establish a long-term maintenance mechanism to ensure the stable operation of the equipment and the sustainability of fecal waste resource utilization.
