Description
Technical field
The utility model relates to a kind of water treatment device, refers to especially organic wastewater with difficult degradation thereby, high density, device that high chroma organic waste water is handled and the advanced treatment of tap water, the terminal and the pretreatment unit of high purity water.
Background technology
In recent decades, because developing rapidly of organic chemical industry, petrochemical complex, medicine, agrochemical industry, the kind and the output of organic compound grow with each passing day, and having entered particularly water surrounding of human environment by various approach, the organism in the water surrounding has 96000 kinds more than approximately according to estimates.They are very big to the harm of environment.No matter be river, river, lake water, waste water or tap water, organic pollutant has wherein become the principal contradiction that water pollutes, and the organic pollutant of removing in the water has become one of top priority of water treatment.
But traditional biochemical treatment often is difficult to reach treatment effect preferably.And start under the rayed excite transitions of electronics in the semi-conductor, with UV/TiO
2If the most common photochemical catalytic oxidation has been proved to be the enough reaction times, just can be CO with the organism permineralization
2And H
2Simple inorganics such as O.But based on following two reasons, photocatalysis oxidation technique is not applied to actual engineering of water treatment so far.One, traditional suspending phase photochemical catalytic oxidation is directly with TiO
2Powder places waste water by UV-irradiation, TiO after reaction is finished
2Powder is not only time-consuming but also require great effort with separating of water; Its two, traditional stationary phase photochemical catalytic oxidation adopts methods such as colloidal sol-gel or vapor deposition to make TiO in advance on carriers such as glass fibre (cloth), glass sphere
2Film, film complexity, cost height, and film forming thickness is very limited, and the efficient of photocatalysis oxidation reaction is low, is difficult to adapt to the requirement of actual engineering.Simultaneously, cleaning behind the photocatalyst film " poisoning " or replacing are all undesirable or complicated, thereby have also limited the process that photocatalysis oxidation technique transformed to the practical stage.
China utility model patent ZL96229378.4 discloses a kind of filtering apparatus for drinking water, adopts diatomite as flocculating aids, can instant film forming, instant recoil wash off on the filter element that stainless (steel) wire is made.But this device only limits to filteration, only can remove suspended substance and colloid in the water, to almost not removal effect of deliquescent organism in the water.
Summary of the invention
The purpose of this utility model is at the problems referred to above, design a kind of efficient, cheap, cleaned and changed photocatalyst film of coating and can remove organic novel photocatalysis oxidized water treatment equipment in the water easily, satisfy dirt, the wastewater discharge standard requirement of increasingly stringent, and solve the difficulty of shortage of water resources.
In order to achieve the above object, the utility model is performed such: comprise flanged (FLGD) spherical upper cover, taper lower cover, cylindrical housings, filter element, foraminous dividing plate.The foraminous dividing plate is divided into upper and lower two portions with the utility model, and top is clean water chamber, and the bottom is the photocatalysis oxidation reaction chamber.Filter element is is firmly connected and composed by top retaining plate, top board, base plate, post, Stainless Steel Cloth, and places in the housing.Be connected with filter element nut, filter element bolting with the foraminous dividing plate with the top retaining plate that filter element is solidified as a whole.By screw bolt and nut flanged (FLGD) spherical upper cover, the foraminous dividing plate of intrinsic filter element, cylindrical housings are solidified as a whole.Its structural feature is: the inside of filter element is provided with the ultraviolet germicidal lamp that has quartz socket tube.Ultraviolet germicidal lamp passes upper cover and is connected with power supply.Stainless Steel Wire can apply or remove photocatalyst film on the net as required immediately, removes organic processing requirement in the water to satisfy.
Characteristics of the present utility model and advantage comprise:
1. because the utility model need not film forming in advance, be that the scene forms photocatalyst film immediately on filter element, and under the ultraviolet germicidal lamp effect, carry out photochemical catalytic oxidation and smart filter and disinfection, so can also remove turbidity, SS, colloid, suspended substance and the floating matter of water in the various organic whiles of thorough removal, the turbidity of filter back water can reach zero Ntu, and water quality is limpid bright, and the utility model treatment effect is good.
2. photocatalyst film thickness of the present utility model, aperture and ultraviolet light intensity can be adjusted at any time, and not only photochemical catalytic oxidation ability is 3-5 times of traditional photocatalytic oxidation device, and has the essence filter effect that traditional photocatalytic oxidation device does not have.
Since the utility model through after the reaction of certain hour and filtering, stifled and cause aquifer yield to descend as photocatalyst film, or remove the effect of pollutent when undesirable by dirt, then can utilize intake pump easily the photocatalyst film recoil to be washed off.Photocatalyst under the back flushing can also utilize once more.So the utility model has not only solved the separation problem of reaction back photocatalyst and water, but also can reclaim photocatalyst, working cost is low.
4, because filter element can be set up in advance, and the ultraviolet germicidal lamp of setting can take out from upper cover and change, so the utility model is rational in infrastructure, it is easy to maintenance to make.
5. the utility model is of many uses, both can be used as the processing of various organic waste waters separately, can be used as the pre-treatment or the terminal process of conventional water treatment process again, water outlet can directly be discharged or reuse, saves precipitation, air supporting or other filtration means and terminal sterilisation measure.
