Technical Field
The utility model relates to a pig raising biogas slurry movable processing apparatus.
Background
The pig raising biogas slurry is pig raising wastewater anaerobic digestion solution, and is residual solution of organic matters such as pig farm feces and the like after anaerobic fermentation under certain conditions. Most of the large-scale pig farms in China are equipped with anaerobic fermentation devices, but the anaerobic technology can only remove organic matters but basically has no capability of removing ammonia nitrogen, and the problems of high ammonia nitrogen concentration, low COD/TN, poor biodegradability and high biological treatment difficulty of the discharged biogas slurry are caused. If the waste water is directly discharged into the environment, serious environmental pollution can be caused.
At present, natural treatment, resource utilization and biological treatment are mainly adopted as biogas slurry treatment methods. The main natural treatment modes include artificial wetlands, stabilization ponds and the like, but the natural treatment mode has large floor area, the treatment effect is easily influenced by regions, air temperature and seasons, and the treatment effect is unstable. The biogas slurry contains a large amount of elements such as nitrogen, phosphorus, potassium and the like, and simultaneously contains a plurality of trace elements, organic acid and the like, so that the biogas slurry is an ideal fertilizer for plant growth. The method can recover elements such as nitrogen and phosphorus in the biogas slurry, and is also a direction for recycling the biogas slurry. But this type of technology is currently mainly focused on laboratory performance. Common biological treatment methods are MBBR (moving bed biofilm reactor), BF-MBR (biofilm membrane bioreactor), A/O-MBR (anoxic/aerobic-membrane bioreactor), and the like. Due to the extremely low carbon-nitrogen ratio of the biogas slurry, the TN (total nitrogen) removal efficiency is generally poor, and the application of a biological method is limited.
