Novel alga-active sludge coupling reactor and antibiotic removing method

Abstract

A novel alga-active sludge coupling reactor is mainly composed of an air pump, constant-temperature water bath, an alga reactor, a filter and an active sludge reactor. Supplementing of CO2 and light supplementing through a plant growing lamp are adopted for the alga reactor, the air pump provides air with positive pressure, and the air is heated to proper temperature through the constant-temperature water bath and then delivered to an aeration ring and an aeration head which bubbles and floats up to drive drive antibiotic wastewater to be in flexible power directional circulation. The antibiotic removing method includes: feeding antibiotic wastewater to be treated into the alga reactor for initial treatment through which part of antibiotic can be removed and activity of antibiotic capable of inhibiting certain microorganisms in sludge can be lowered effectively; filtering the antibiotic wastewater, and feeding the same into the active sludge reactor for further thorough treatment. When the novel alga-active sludge coupling reactor is adopted to remove the antibiotic, efficiency is high, cost is low, operation is convenient, and environment friendliness is realized. The novel alga-active sludge coupling reactor can be applied in treatment of other organic matters and heavy metal wastewater and has extremely wide application prospect.

Description

technical field [0001] The invention relates to a waste water treatment system in the fields of medical treatment, pharmacy, livestock breeding, agriculture, aquaculture and the like, in particular to a novel algae-activated sludge coupling reactor and a method for removing antibiotic cords. Background technique [0002] Medical treatment, pharmaceuticals, livestock breeding, agriculture, aquaculture and other fields all produce a large amount of wastewater rich in antibiotics. Recently, a newspaper publicly reported that in 2013, my country’s antibiotic consumption amounted to 162,000 tons, accounting for about half of the world’s consumption, of which 52% was for animals, 48% was for humans, and more than 50,000 tons of antibiotics were discharged into the natural water and soil environment , has brought a huge threat to the water quality security in areas where surface water is used as drinking water source. The hazards of antibiotic residues are mainly reflected in two a...

Problems solved by technology

The supplementary light sources used in the existing conventional algae technology are mostly incandescent lamps, fluorescent lamps, and high-pressure sodium lamps. The common disadvantages of these light sources are that the wavelength cannot be effectively controlled, the luminous efficiency is low, and most of the electric energy is converted into heat. The photosynthetic radiation efficiency of algae is low

Therefore, the treatment effect of a single algae process is not ideal,

Especially antibiotic wastewater has the characteristics of complex composition, many types of organic pollutants, low biodegradability, and biological toxicity. It is difficult to achieve the desired effect with a single algae treatment process
