Description

A kind of UV/H 2O 2Advanced oxidized water treatment equipment

Technical field

The utility model relates to a kind of UV/H ₂O ₂Advanced oxidized water treatment equipment belongs to the water treatment facilities technical field.

Background technology

Modern industry also will contain a large amount of poisonous and harmfuls, bio-refractory when constantly developing pollutent waste water enters in the environment, causes the severe contamination of water quality.The conventional water treatment processes such as the coagulation that water factory's tradition adopts, precipitation, filtration, sterilization have been difficult to tackle complicated source quality.The quality problem of water factory's water outlet embodied a concentrated expression of smell flavor, aspect such as disinfection byproduct (DBP) is many, hydrochemistry is stable and biologically stable is relatively poor, especially output water is transported in user's the process by the huge pipe network system of complexity, often owing to be subjected to the secondary pollution of pipe network, make water quality not reach national standard, even severe exacerbation, jeopardize people's health.Therefore, research and develop new and effective water technology, become one of focus of water treatment field.

Advanced oxidation processes is a kind of new life's a water technology, but the efficient degradation organism mainly comprises chemical oxidation, photochemical catalytic oxidation, wet oxidation, supercritical water oxidation etc.UV/H wherein ₂O ₂The system method for oxidation is a kind of of chemical oxidation, because technology is relatively simple, and does not produce any solid waste in the processing procedure, is widely used in recent years in the advanced treating of drinking water.H ₂O ₂Oxidation be because H ₂O ₂Under the effect of ultraviolet, can produce the extremely strong OH of oxidisability, make organic pollution oxidized and degraded.But at UV/H ₂O ₂In the technology, H ₂O ₂Photolysis efficiency lower, so need add the H of high concentration ₂O ₂But from toxicologic angle, the H of high concentration ₂O ₂Infeasible.And H ₂O ₂With being swift in response of chlorine, so unnecessary H ₂O ₂Be necessary to remove by biofiltration, so also increased to a certain extent processing cost.Therefore, how to improve H ₂O ₂Photolysis efficiency, reached and both improved purification efficiency, exceed again the effect that increases processing cost, be a problem that needs to be resolved hurrily at present.

Summary of the invention

For solving the problem of above-mentioned existence, the utility model provides a kind of UV/H ₂O ₂Advanced oxidized water treatment equipment with effective prolongation ultraviolet irradiation time, is given full play to the oxidation of hydroxyl radical free radical, removes organic pollutants, improves purification efficiency.

The present invention is achieved by the following technical solutions:

Described UV/H ₂O ₂Advanced oxidized water treatment equipment comprises H ₂O ₂Throwing device and reactor, described H ₂O ₂Throwing device is made up of the dosing tank, flowmeter and the ejector that connect successively; Described reactor comprises the housing establishing water inlet, top and set out the mouth of a river in a bottom, it is outside and be communicated with the water inlet of housing and the ring glass pipe of delivery port to be arranged at the uviol lamp on the enclosure interior axis and to be surrounded on uviol lamp; The delivery port of described ejector is communicated with the water inlet of housing.

For reaching decontamination effect improving preferably, the two ends of described ultraviolet lamp are separately fixed at the bottom and the top of housing, and the power of ultraviolet lamp is 20～60W; The internal diameter of described ring glass pipe is 100～150mm; The residence time of processed water in the ring glass pipe is 10～30min.

The method of using above-mentioned water treatment facilities to carry out water treatment comprises the steps: that (1) prepare certain density H in advance ₂O ₂Solution places in the dosing tank, adds continuously H by the ejector siphon ₂O ₂And mix, and regulate by flowmeter that to add concentration be 0.5～1.0mg/L; (2) the above-mentioned H that added ₂O ₂Former water from the water inlet inflow reactor of ejector delivery port through reactor shell, flow from bottom to top at the irradiation lower edge of uviol lamp ring glass pipe, guarantee that the time of staying of water in the ring glass pipe is 10～30min, reached preferably clean-up effect.

The beneficial effects of the utility model are: can realize H ₂O ₂The ground automatic feeding takes full advantage of remaining pressure of piping system and need not pressurization; The structural design of ring glass pipe makes and effectively prolonged the time that water is shone by ultraviolet ray in limited space, can give full play to the oxidation of hydroxyl radical free radical, removes organic pollutants, reduce water outlet and smell flavor, improve effluent quality, technological operation is simple, only needs regular replenishment H ₂O ₂Solution is applicable to the advanced treating of Municipal pipe network water, can be used as the pretreatment unit of piped direct-drinking water technology.
