After the first filter layer 4 and the second filter layer 6 work for a period of time, the cobblestone surface can be stained with the sediment, if not in time clear up can influence the filter effect, at this moment, need to put the baffle card in the below of water pipe 7, the connector 18 of back flush unit 5 is connected with external clean water reservoir, the clean water in the clean water reservoir is sent into the water pipe 7 that the upper portion opened the outlet hole through connector 18, respectively to the first filter layer 4 and the second filter layer 6 a large amount of water spray of upper portion through the outlet hole, form reverse flushing, until the sediment that the cobblestone was stained with is washed away completely, then the sewage that is washed down and has the sediment flows back to the baffle, later discharge filter tower 2 through the drain that is connected with the baffle, take out the baffle after the sewage is completely got rid of, block up the drain, carry out the sewage once more to the sewage and.

The sponge filter layer 8 is movably arranged between the second filter layer 6 and the connecting pipe 9, water filtered by the first filter layer 4 and the second filter layer 6 enters the sponge filter layer 8 under the action of gravity, the sponge filter layer 8 can filter small particulate matters in the water, and the removal rate of the particulate matters filtered by the sponge filter layer 8 reaches more than 99%. After the sponge filter layer 8 is filtered for a period of time, small particulate matters can be accumulated on the surface, the influence of untimely cleaning is influenced to secondary filtering, at the moment, the sponge filter layer 8 needs to be taken out from the inside of the filter tower 2, and after the small particulate matters are cleaned, the small particulate matters are placed back into the filter tower 2 again to filter sewage again.

As shown in fig. 1, a sewage disinfection device is arranged in the disinfection tower 17 and is arranged between the connecting pipe 9 and the water outlet 16. The sewage disinfection device comprises an active carbon adsorption layer 11, a light oxygen disinfection layer 12 and an ozone disinfection layer 15 which are arranged from bottom to top, and the arrangement can delay the water flow speed, is favorable for prolonging the retention time of water needing disinfection in a disinfection tower 17, and is favorable for disinfection.

Activated carbon adsorption layer 11 sets up in the top of connecting pipe 9, activated carbon is applied to water treatment and has had very long history, dechlorination at water, remove the absorption of smelling and pollutant etc. and play important effect, activated carbon is the carbonaceous material that uses porousity, not only have the micromolecule organic matter that the absorption preceding stage leaked and come, also have obvious absorption removal effect to aquatic peculiar smell, colloid and pigment, heavy metal ion etc. still have the effect that reduces COD, can further reduce the SDI value that RO intake, guarantee SDI <5, TOC <2. Oppm.

The water after being adsorbed by the activated carbon adsorption layer 11 upwards enters the photo-oxidation disinfection layer 12, the photo-oxidation disinfection layer 12 is internally provided with the photo-oxidation tubes 13 which are uniformly distributed, the photo-oxidation tubes 13 emit light to release ultraviolet rays, the water body is disinfected and disinfected by the ultraviolet rays, the flowing water flow is disinfected and disinfected safely and securely, chemical agents are not added in the disinfection process, the smell and the taste of the water are not increased, toxic and harmful byproducts are not generated, the water body is not influenced by the water temperature and the pH value, the disinfection speed is high, the efficiency is high, the equipment operation is simple, the operation management is convenient, the automation is realized, and the like, and the device is gradually widely applied. Compared with other sterilization modes, the sterilization is more thorough and effective, no secondary pollution is generated, and the cost is low.

The water after passing through the photo-oxidation disinfection layer is upwards sent into an ozone disinfection layer 15, an ozone pipe 14 connected with an ozone generator is arranged in the ozone disinfection layer 15, and air outlet holes for ozone to pass through are uniformly formed in the pipe wall of the ozone pipe 14. After the ozone sent out by the air outlet is dissolved in water, inorganic matters and organic matters in the water are directly oxidized or indirectly oxidized by a large amount of radical free radicals and nascent oxygen generated in the reaction and enter cells of bacteria to oxidize the intracellular organic matters, so that the aims of sterilizing, disinfecting and purifying the water quality are fulfilled, the disinfecting effect is better, and the taste and the impression of the water can be improved. The purified water sterilized by the ozone sterilizing layer 15 flows upward and is discharged from the water outlet 16.

After passing through the disinfection tower 17, the sewage disinfection effect is remarkable, viruses, germs, disinfectors, organic solvents and the like in water can be oxidized and decomposed, and the sewage disinfection tower can be completely used for retreatment of water at the tail end of a hospital and is necessary to be popularized.
