Abstract

The invention discloses a rapid enrichment culture method for efficient anaerobic dephosphorization bacteria, the method comprises the following steps that an anaerobic dephosphorization bacteria enrichment medium is arranged at first; a trace element solution and a vitamin solution are added to the culture medium for performing anaerobic dephosphorization bacteria enrichment; then, the anaerobicdephosphorization bacteria isolation medium is arranged for purification and separation of the anaerobic dephosphorization bacteria. The enrichment culture method lays a foundation for research on physiological characteristics of the anaerobic dephosphorization bacteria by the enrichment, separation and purification of the efficient anaerobic dephosphorization bacteria, and provides theoretical support for fully understanding phosphorus circulation pathway in sewage treatment process. An efficient anaerobic dephosphorization bacteria agent can enhance dephosphorization effect in the sewage treatment process, the method provides a basis for development of a new dephosphorization process with low energy consumption and high efficiency, and solves phosphorus removal difficulties in the sewagetreatment process.

Description

technical field [0001] The invention relates to a method for rapidly enriching and cultivating high-efficiency anaerobic phosphorus-removing bacteria. Background technique [0002] Phosphorus is an important factor causing water eutrophication. In water polluted by phosphorus, algae multiply in large numbers, and after the algae die, they decompose and produce toxic and harmful substances. Therefore, it is of great significance to reduce the phosphorus in sewage. At present, the main methods for removing phosphorus in wastewater are chemical and biological methods. The disadvantage of chemical phosphorus removal is that it consumes chemicals and produces a large amount of chemical sludge. The treatment cost is high and it is easy to cause secondary pollution; while biological phosphorus removal is more economical. , and the phosphorus removal by phosphorus accumulating bacteria is the current research hotspot in this field. However, phosphorus-accumulating bacteria also ha...
