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 the sewage treatment, and discloses a method for treating a black and odorous water body by using an airlift circulation algae bio-membrane reactor. Themethod comprises the following steps: enabling chlorella pyrenoidosa to be inoculated on a bio-cord carrier for performing biofilm culturing, importing the black and odorous water body from a water inlet to a cylinder of the reactor, and opening a light source and an aerating device, lifting air and dividing the reactor to a flow rising area and a flow reducing area through a flow guide cylinder,enabling the bio-cord carrier to be positioned in the flow rising area, removing nitrogen and phosphorus pollutants in the black and odorous water body through a mixing nutrition growth reaction by the chlorella pyrenoidosa on the bio-cord carrier, after that, closing the light source and the aerating device, stewing, finally discharging treated water from a water outlet. The method has the advantages of low operation cost, good effluent quality, easy harvesting of algae and the like, and has larger application potential in the aspect of treating the black and odorous water body.

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...
