Livestock wastewater mainly comes from animal excrement and production activities, and is rich in high concentrations of organic matter, suspended solids, and ammonia nitrogen; Slaughter wastewater originates from various stages of the slaughter process, containing a large amount of organic matter such as blood, feces, oil, and high concentrations of nitrogen and phosphorus nutrients.

Wastewater characteristics: high organic content, high suspended solids, and abundant ammonia nitrogen and nutrients.

Core processing technologies: high-efficiency anaerobic reactor, improved aerated biofilter.

Efficient Anaerobic Reactor (Improved UASB/IC/EGSB Reactor)

The process technology principles of improved UASB/IC/EGSB anaerobic reactors used in the treatment of aquaculture and slaughter wastewater are mainly based on the decomposition of organic matter by anaerobic microorganisms under anaerobic conditions.

Improved biological aerated filter (BAF)

The process technology principle of the improved biological aerated filter (BAF) in the treatment of aquaculture and slaughter wastewater mainly uses the biodegradation of microorganisms to remove pollutants from the wastewater, thereby achieving the goal of water purification.

Technical advantages of high-efficiency anaerobic reactor (improved UASB/IC/EGSB reactor):

Efficient processing: The volumetric load can reach 10-20kg (COD)/(m³·d);

Energy recovery: The generated methane gas can be used as renewable energy, bringing additional economic benefits to enterprises;

Energy saving and consumption reducing: adopting anaerobic treatment process reduces oxygen supply demand and saves energy consumption of aeration equipment;

Low sludge production: Low sludge production and high sludge stability, easy to handle;

Strong adaptability: capable of treating wastewater of different concentrations and compositions, especially for organic wastewater, with more significant treatment effects.

Technical advantages of improved biological aerated filter (BAF):

Efficient removal of pollutants: effectively removing organic matter, suspended solids, ammonia nitrogen and other pollutants to meet emission standards or reuse water quality requirements;

Strong resistance to impact loads: Aerated biofilters are insensitive to changes in organic and hydraulic loads, and there is no sludge expansion problem;

High oxygen transfer efficiency: The utilization rate of oxygen can reach 20%~30%, and the aeration rate is lower than that of general biological treatment;

Easy to film and fast to start: Short debugging time, generally only 7-12 days, no need to inoculate sludge, using natural film domestication;

Smart and energy-saving: The system can perform online detection of water quality, water quantity, and dissolved oxygen concentration, and adjust the aeration duration to control the oxygen supply of the fan, achieving intelligent operation, energy saving, and consumption reduction;

Modular structure: flexible combination according to actual needs.
