For ease of understanding, the workflow of the present invention is specifically described below:
the sewage containing a certain suspended solid and other substances enters the regulating box 12 through the water inlet 11, the regulating box 12 regulates the water quantity and the water quality of the sewage, and the impact of flow and pollution load on the filtering process is reduced. The sewage passing through the regulating box 12 enters the horn water distribution port 14 which is vertically and upwards arranged at the large mouth end along the water guide pipe 13, the axis of the horn water distribution port 14 coincides with the axis of the gathering tower top 21 and the tower body 26, the sewage flows upwards and peripherally through the horn water distribution port 14, the sewage uniformly flows downwards along the gap of the spherical filter material 3 due to no water outlet path at the upper part, and the spherical filter material 3 has the interception function on suspended solids and other substances in the sewage, the sewage is purified after being filtered, and then reaches the water outlet 25 for discharging through the water outlet 24 communicated with the lower end part of the tower body 26. Suspended solids and other substances carried by the sewage retained in the floating filler 3 can gradually accumulate in the filter material gaps from the height position of the horn water distribution port 14, and the accumulated suspended solids are required to be eluted and discharged to ensure that the filtering effect of the filtering tank is always maintained. Under the aggregation action of the aggregation tower top 21, the spherical filter materials 3 are collected to the aggregation tower top 21, and the spherical filter materials 3 are extruded out through the filter material conveying pipe 22 at the upper part of the aggregation tower top 21 due to the fact that the spherical filter materials 3 are subjected to larger buoyancy. Because the filter material conveying pipe 22 is communicated with the horizontal auger 23, when the horizontal auger 23 is static, the spherical filter material 3 is intercepted in the conveying pipe 22, and when the horizontal auger 23 is started to rotate for conveying, the spherical filter material 3 and suspended solids and other substances carried by gaps of the spherical filter material 3 are conveyed to the filter material separating chamber 41 of the filter material separating circulator 4, and because the water inlet 11 is higher than the horizontal auger 23, the height of the horizontal auger 23 is lower than the water level line of the filter material separating chamber 41. Since the horizontal auger 23 agitates and grinds the spherical filter material 3 during the conveying process, suspended solids and the like adhering to the spherical filter material 3 are separated from the spherical filter material 3. The spherical filter material 3 and suspended solids carried by the gaps thereof, which are fed into the filter material separating chamber 41, are separated, the spherical filter material 3 naturally floats upward, and the suspended solids remain in the water to form muddy water. The spherical filter material 3 floating in the filter material separating chamber 41 enters from the inlet of the vertical auger 42, is pushed to the filter material reflux outlet 44 by the vertical auger 42 along the filter material reflux pipe 43, and the spherical filter material 3 pushed to the filter material reflux outlet 44 overflows and floats to the bottom of the upper filter material column, and becomes the effective filter material of the filter material layer again. The mud water in the lower part of the filter material separating chamber 41 is continuously thickened, and the mud water discharge valve 45 can be opened periodically to discharge the enriched mud water through the mud water discharge pipe 46. The whole system continuously receives the spherical filter materials 3 from the filter tank 2 through the bypass filter material separation circulator 4 for conveying, kneading, backwashing and floatation, and conveys the spherical filter materials 3 after backwashing and floatation to the lower part of the filter materials in the tower body 26. Thus, the spherical filter material 3 is continuously and circularly backwashed in the system, and the filter system works continuously, so that continuous flow work of the filter system is realized.
Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications and equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all such modifications and equivalents are intended to be encompassed in the scope of the claims of the present invention.
