How does Fermentation Bio-reactor efficiently purify rural wastewater through functional microbial communities and intelligent design?

Against the backdrop of comprehensively promoting rural revitalization and improving the rural living environment, rural domestic wastewater treatment faces real challenges such as complex water quality, high nitrogen and phosphorus concentrations, and weak operation and maintenance capabilities. The Fermentation Bio-reactor (FBR) purification tank, an integrated wastewater treatment device specifically developed for the needs of rural China, integrates advanced Japanese purification tank manufacturing concepts with localized microbial technology. Leveraging Futong's proprietary FB series functional microbial communities, stable operating performance, intelligent management, and economic practicality, it has become a reliable solution for achieving wastewater resource recovery and ecological treatment.
The core advantage of Fermentation Bio-reactor stems from its unique bio-enhancing mechanism. The built-in FB series functional microbial communities—including highly efficient denitrifying bacteria, polyphosphate-accumulating bacteria, oil-removing bacteria, and various COD-reducing bacteria—are all selected from the natural environment and possess strong adaptability and metabolic activity. These microbial strains work synergistically to simultaneously complete organic matter degradation, ammonia nitrification/denitrification, biological phosphorus removal, and oil decomposition within a single reactor, significantly improving the removal efficiency of total nitrogen (TN) and total phosphorus (TP). The effluent quality consistently meets the Class A standard of the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" (GB 18918-2002) or even stricter local requirements, effectively curbing the risk of eutrophication.
The structural design integrates mature experience from Japanese septic tanks with the realities of rural China. It utilizes a high-strength fiberglass or PE one-piece molded tank, which is corrosion-resistant, leak-proof, and has a lifespan of over 20 years. The internal compartments are scientifically divided into anaerobic, anoxic, aerobic, and sedimentation zones. Low-energy circulation is achieved through airlift reflux and a microporous aeration system, eliminating the need for external water pumps for sludge return and mixed liquor mixing. The equipment is buried underground, occupying only 3-6 square meters, allowing for land reclamation or paving, without affecting the original spatial layout of the village.
Intelligent operation and maintenance significantly lowers the management threshold. Equipped with an IoT remote monitoring module, it can collect real-time data on dissolved oxygen, pH, water level, and operational status. Abnormal situations trigger automatic alarms and push notifications to village administrators' mobile phones. Low-power fans and intermittent aeration strategies keep daily power consumption between 0.8 and 1.2 kWh, with annual maintenance costs less than 300 yuan per household. With no complex mechanical parts, it essentially achieves "unmanned operation and regular inspections," making it particularly suitable for remote villages lacking specialized technical personnel.
Economic and ecological benefits are equally outstanding. The equipment is prefabricated in the factory and installed on-site, resulting in a short construction period and minimal civil engineering work. No chemical additives are required, reducing sludge production by more than 40% compared to traditional processes, and the sludge can be used as agricultural organic fertilizer after stabilization treatment. The total life-cycle cost is far lower than the centralized pipe network + sewage treatment plant model, truly achieving "affordable construction, affordable use, and effective management."
Ultimately, the value of the fermentation bio-reactor lies not only in "treating sewage," but also in its ability to activate the self-repairing capabilities of rural aquatic ecosystems through the power of microorganisms. When a pool of murky domestic sewage is purified and reused, and when fish and shrimp reappear in the village ditches, this technology becomes a silent guardian of the green mountains and clear waters. Today, as ecological civilization and the construction of beautiful villages are being deeply promoted, fermentation bio-reactor is writing a new paradigm for rural sewage treatment in China through the harmonious coexistence of technology and nature.
