Problems solved by technology

However, the main body of biodegradation in the air-lift internal circulation packing bioreactor is still activated sludge, and the phosphorus removal effect of the reactor is poor, which cannot meet the needs of nitrogen and phosphorus removal in black and odorous water bodies.

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a method for treating black and odorous water bodies by using an air-lift circulation algae biofilm reactor. Inoculate Chlorella pyrenoidosa on the biological rope carrier for film-hanging culture, introduce the black and odorous water from the water inlet into the column of the reactor, then turn on the light source and aeration device, and the gas rises through the guide tube to divide the reactor into Upwelling zone and downwelling zone, the biological rope carrier is located in the upwelling zone, Chlorella pyrenoidosa on the biological rope carrier removes nitrogen and phosphorus pollutants in black and odorous water through mixed vegetative growth reaction, and then turns off the light source and aeration device Stand still, and finally discharge the treated water from the water outlet. The device and method of the invention have the advantages of low operating cost, good effluent quality, easy harvesting of algae, etc., and have great application potential in the treatment of black and odorous water bodies.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a method for treating black and odorous water bodies by using an airlift circulation algae biofilm reactor. Background technique [0002] In recent years, the black and odorous water bodies in cities have gradually increased, and the treatment of black and odorous water bodies is imminent. Aiming at the root cause of the formation of black and odorous water bodies - the excessive nitrogen, phosphorus and organic pollutants in water bodies, the commonly used treatment methods are physical, chemical and biological methods. Due to the advantages of environmental friendliness and ecological energy saving, the biological method has become the most promising method for the treatment of black and odorous water bodies. Although the traditional biological method such as activated sludge method and the new technology developed on this basis can remove more than 90% of...
