Pretreatment Equipment
It is mainly used to remove suspended impurities in Wastewater and reduce the load for subsequent advanced treatment, serving as the foundation of the Wastewater treatment process. As the first barrier, grilles are divided into coarse grilles and fine grilles. They intercept large suspended solids such as fecal residues, crop straws and plastic bags through grille bars, preventing blockage of subsequent pipelines and equipment. Common types include mechanical grilles and manual grilles. Large-scale farms mostly adopt mechanical grilles for automatic slag removal and labor cost saving.
Sedimentation tanks separate suspended particles by gravity settling principle. The commonly used types in farms are horizontal flow sedimentation tanks, vertical flow sedimentation tanks and inclined tube sedimentation tanks. Among them, inclined tube sedimentation tanks feature high settling efficiency and small footprint, making them more suitable for small and medium-sized farms. After sedimentation treatment, the removal rate of suspended solids can reach 60%-80%, achieving preliminary water purification. Solid-liquid separators can quickly separate solid pollutants such as manure from Wastewater, and the separated solid residues can be further processed into organic fertilizer to realize resource recycling.

Biochemical Wastewater Treatment Equipment
Biochemical treatment is the core process to decompose organic pollutants, nitrogen and phosphorus in Wastewater. For high-concentration organic wastewater such as farm Wastewater, biochemical equipment decomposes pollutants into harmless carbon dioxide and water through microbial metabolism. Common biochemical equipment includes integrated Wastewater treatment equipment, anaerobic reactors and aerobic aeration tanks. Integrated Wastewater treatment equipment integrates pretreatment, biochemical treatment and advanced treatment. It features small footprint, simple operation and high treatment efficiency, perfectly suitable for small and medium-sized farms. It can be buried underground without affecting normal farm production.

Anaerobic reactors are suitable for high-concentration organic Wastewater. Under oxygen-free conditions, anaerobic bacteria decompose organic matter into biogas, which can be used as clean energy for energy recovery, ideal for large-scale farms. Aerobic aeration tanks inject oxygen into Wastewater through aeration devices to cultivate aerobic microorganisms, efficiently decomposing organic matter and making the effluent meet discharge standards.

Advanced Treatment and Disinfection Equipment
Biochemically treated Wastewater still contains a small amount of pollutants and pathogens, requiring further treatment to meet discharge or reuse standards. Common advanced treatment equipment includes water filtration equipment and ultrafiltration equipment, which can remove fine suspended solids and residual pollutants to improve water quality. Disinfection equipment is used to kill bacteria, viruses and other pathogens. Typical types include ultraviolet sterilizers and chlorine dioxide generators. In particular, ultraviolet sterilizers feature high disinfection efficiency and no secondary pollution, widely applied in farm Wastewater treatment.
