Embodiment Construction

[0007] Below in conjunction with embodiment, the present invention is further described. The coking plant discharges 120,000m of coke-washed sewage every day 3 , The coke-washed sewage contains 1.48% ammonia, 1.3% nitrogen, 1.37% benzene, and 1.7% hydrogen sulfide. For the above-mentioned toxic and harmful substances. The sewage flowing in from the sewage inlet 1 enters the first treatment tank 6, and at the same time, the scraping machine 2 rotates the scraping blade 3, which can effectively scrape and float all sundries and oils floating on the sewage surface after rotation. The particulate matter settles to the bottom of the first treatment tank 6. After the overflowing sewage is filtered by the filter device 4 for one hour, it is automatically backwashed by the filter device 5 . Impurities after backwashing settle to the bottom of the first treatment tank 6 . When the sediment is accumulated for a long time, it will be discharged into the sludge pool 18 through the blo...

Abstract

The present invention discloses photocatalytic sewage treating apparatus and method with nanometer titania net. The present invention has high sewage treating capacity and low running cost. Technologically, the sewage treating apparatus includes a treating pond with floating matter scraping machine, filtering unit and automatic back flushing unit; several combined nanometer titania nets inside water; and ultraviolet reflecting hoods over the sewage treating pond controlled with photosensitive inductor to reflect ultraviolet into the pond properly. Through oxidation, decomposing and degradation, the present invention eliminate organic and inorganic pollutant from sewage.

Description

technical field [0001] The invention relates to a sewage treatment device. More specifically, the present invention adopts nano titanium dioxide TiO 2 The mesh, using sunlight and ultraviolet light, catalyzes sewage treatment plants. It is known from the International Patent Classification that it belongs to the category of C02F sewage treatment devices. Background technique [0002] People know that the treatment of iron and steel enterprises, chemical enterprises and urban domestic sewage, chemical method, biological treatment method, drug delivery type treatment. According to the prior art method for sewage treatment, many enterprises can afford to build sewage treatment plants, but cannot afford to invest in operating costs. Especially the sewage generated by coking plants in iron and steel enterprises contains ammonia, nitrogen, benzene and hydrogen sulfide. Although put into biological medicine and chemical medicine, also can't decompo...
