Recommendation of Biodegradable Mobile Toilets
It is recommended to use ecological public toilets with microbial degradation technology and microbial degradation environmental protection toilet devices. Here are the details:
I. Ecological Public Toilets with Microbial Degradation Technology This type of toilet decomposes excrement through highly efficient microbial degradation strains, achieving a high degree of reduction. The temperature generated by biological reactions can reach 50 - 65℃, or even above 60℃ - 70℃, effectively killing pathogenic microorganisms. The decomposition products are mainly carbon dioxide, water, and a small amount of gas, and the residues can be recycled as organic fertilizers. The toilet body adopts an insulating structure such as steel-frame cement composites and is divided into two types: movable and fixed. It does not require the construction of sewer networks and septic tanks, making it suitable for environments without sewer pipes. The design focuses on air circulation, integrating intelligent systems with functions such as air circulation, temperature control (e.g., heated toilet seats), and biological deodorization. It blocks odors through external ventilation pipes, and some models are equipped with intelligent temperature control systems. Its environmental advantages are significant: no water usage or water conservation, reduction of secondary pollution, and resource utilization of excrement. Application cases include six waterless ecological public toilets on the Manxing Footpath along the North Bank of the Yangtze River in Chongqing, as well as more than 300 waterless and flush-free smart ecological toilets used in the 2022 Beijing Winter Olympics.
II. Microbial Degradation Environmental Protection Toilet Devices This device consists of a squatting pan, exhaust pipe, fermentation and degradation tank, mechanical transmission device, and electrical PLC constant temperature and humidity control device. The materials can be selected from color-coated steel plates, carved panels, aluminum-plastic panels, etc. It is suitable for a temperature range of -30℃ to 50℃ and operates at a voltage of 220V. Excrement is mixed and stirred with microbial strain carriers through mechanical transmission and is digested and degraded into compliant gas emissions under the action of microorganisms. The daily power consumption is approximately 3 - 5 degrees (depending on the number of users), and the strain replacement cycle is 3 - 6 months, costing 300 - 500 yuan per toilet stall. Its characteristics include being flush-free, requiring no waste removal, being pollution-free, clean and hygienic, environmentally friendly and energy-saving,不受气温限制 (not restricted by temperature), and having a wide range of applicable regions. This technology has been included in the National 863 Program, passed the safety inspection of microbial agents in Shanghai, achieved standardized production in enterprises, and applied for 20 patents. A typical product, such as the "Eco-Clean" microbial degradation ecological environmental protection toilet, can efficiently decompose excrement, achieving in-situ non-incremental and harmless treatment.
