Abstract

The utility model discloses a photocatalytic reactor for treating persistent organism in drinking water. A water pump (7), an air pump (8) and a support (11) are placed on an operation desk (12). A reactor shell (4) is internally provided with a vertical flow type folded plate (3). A short-wave ultraviolet radiator (1) is placed in a quartz socket tube (2), which are respectively inserted in the reactor shell (4). One side of the reactor shell (4) is provided with an inlet valve (6) and the other side of the reactor shell is provided with an outlet valve (5). The air pump (8) is connected with the reactor shell (4) through an air tube (10). The photocatalytic reactor is small in size, good in treatment effect and convenient to operate and manage. The wall of the reactor adopts the form of the folded plate to from isotropic turbulence, thus leading to full contact between pollutants and catalyst in solution and enlarging the effect of mass transfer. Simultaneously, in the reactor, the pollutants absorbed on the catalyst can all be in contact with ultraviolet light under the action of turbulence to cause photooxidative degradation and renew the active surface of the catalyst, thus greatly prolonging the service life of the catalyst.

Description

The photo catalysis reactor of hardly degraded organic substance in the processing drinking water

Technical field

The utility model relates to the photo catalysis reactor of hardly degraded organic substance in micro polluted source processing, the photocatalysis oxidation technique field, particularly processing drinking water.

Background technology

The organic micro-pollution of drinking water source has been general phenomenon, and water quality condition does not improve after existing water-purifying process is handled, and the water quality safety problem of tap water is highlighted day by day, has become a big secret worry of health of people life.Because photochemical catalytic oxidation is very competent, the reaction conditions gentleness, almost can decompose all organic pollutants until forming carbonic acid gas and water, thereby caused the research boom of photocatalysis oxidation technique in environmental area, each progress of photocatalysis technology, all relevant with updating of reactor assembly, this is that its potential application foreground promotes, and also meets the inherent requirement of technical progress development simultaneously.

Photo catalysis reactor has adopted fixedly membrane type photochemical catalysis and two kinds of forms of suspension formula photochemical catalysis at present.Fixing TiO in the film reactor ₂Be fixed on the carrier, reduced the catalyst separating step, simple to operate, the waste water circular treatment, catalyzer uses continuously, can realize catalysis and isolation integral, the good stability of film, but being restricted with the pollutent contact area, speed of reaction is not very high; And TiO in the suspension formula reactor ₂Be suspended in the liquid phase, structure is simple relatively, and big with the pollutent contact area, speed of reaction is higher, but catalyzer is difficult to reclaim, and active ingredient loss is bigger, necessary filtration, centrifugation, flocculation etc. after the reaction.In photocatalysis oxidation technique research in recent years, because the key equipment photo catalysis reactor lacks practical core technology, relevant research all rests on laboratory stage.

Summary of the invention

At quoting organic micro-pollutants difficult degradation in the water, the low problem that reaches photocatalyst reuse difficulty of Treatment by Photocatalysis Oxidation efficient provides a kind to be used for the photo catalysis reactor of processing drinking water Persistent organic pollutants to the purpose of this utility model exactly.

The utility model is achieved in that reactor body part is made up of shell of reactor, vertical-flow flap, quartz socket tube, shortwave uv irradiating lamp, blast main, water intaking valve, outlet valve.Under UV-irradiation and aeration condition, photocatalyst absorbs luminous energy, and adsorbs polluting organism, thereby reaches the purpose of photocatalytic degradation.The uv irradiating lamp of this reactor places in the quartz socket tube, and waste water, is discharged from outlet valve after the reaction times through specific shot in water intaking valve enters vertical-flow flap reactor.

Utility model photocatalyst reactor volume is little, and treatment effect is good, operation and convenient management; Wall of reactor adopts the flap form to form the isotropy turbulent flow, and the pollution substance in the solution is fully contacted with catalyzer, increases mass transfer effect; The pollution substance that is adsorbed on the catalyzer in the reactor all can contact with UV-light under action of turbulent flow simultaneously, and photo-oxidative degradation takes place, and upgrades the activity of such catalysts surface, the work-ing life of improving catalyzer greatly; Reactor integrates absorption and photocatalytic oxidation degradation, and perfection has solved the deficiency of simple function.
