Bolong provides integrated solutions for manure and odor management at large-scale farms, helping them achieve green, clean, and efficient livestock operations.
Numerous large-scale farms currently face manure treatment challenges.Bolong previously resolved such issues for a Vietnamese pig farmer operating a 30,000-head facility, which had long endured problems including manure accumulation, wastewater discharge, and odor nuisance affecting nearby residents.
To address this challenge, the Bolong team designed a customized integrated treatment system centered on a pig manure fermentation tank. This pig manure fermentation tank system achieves harmless and resource-efficient processing of manure, wastewater, and exhaust gases, completely resolving the client's environmental pressures and operational difficulties.
Before adopting the Bolong pig manure fermentation tank system, the farm primarily handled manure through piling or basic composting--methods characterized by lengthy fermentation times, intense odors, and severe pollution.
Wastewater contained high levels of organic matter and ammonia nitrogen, failing to meet discharge standards. Additionally, summertime odor emissions disrupted the lives of nearby villagers.
The client urgently required a system capable of efficient fermentation, odor removal, pollution reduction, energy conservation, and environmental protection—one that would meet regulatory requirements while enabling resource recovery from manure waste.
Addressing these needs, Bolong's engineering team designed a comprehensive pig manure fermentation tank system-comprising fermentation tanks, wastewater treatment, and odor control systems—to achieve full-process management of solids, liquids, and gases.
Pig manure first enters a solid-liquid separator to separate solids from wastewater. Solids proceed directly to the fermentation tank, while liquids enter oxidation ponds for preliminary sedimentation and aeration.
This process significantly reduces subsequent fermentation load and enhances overall treatment efficiency.
Within the Bolong pig manure fermentation tank, manure undergoes temperature- and oxygen-controlled fermentation. Full decomposition occurs within just 7 days, transforming it into high-quality organic fertilizer.
This process effectively eliminates pathogens and insect eggs, markedly reduces odors, and significantly improves environmental conditions.
After treatment in the oxidation tank, wastewater undergoes multi-stage sedimentation, aeration, and flocculation processes.
Following sedimentation of impurities, the treated sludge can be mixed with a specific proportion of manure and reintroduced into fermentation tanks for further processing.
Once treated water meets standards, it is recycled, achieving true zero wastewater discharge.
Exhaust gases generated during fermentation and wastewater treatment are centrally collected into anaerobic tanks.
After purification and refinement, biogas is burned via a small flare to completely eliminate odors, achieving triple harmless treatment of solid, liquid, and gaseous waste.
Following the implementation of the Bolong Pig Manure Fermentation Tank System, customer feedback has been remarkable:
Odor emissions reduced by over 80%;
Wastewater discharge meets environmental standards and enables recycling;
Manure is converted into organic fertilizer, transforming waste into valuable resources;
The entire system operates intelligently, reducing labor and energy costs.
Following the system upgrade, the client's farm achieved more stable overall operations and superior environmental performance, truly transitioning from “pollution control” to “profit generation.” This provides a practical solution for modern large-scale farming.
