Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The upflow combined secondary biofilm sewage treatment integrated equipment includes a shell and seven treatment areas inside the shell. The seven treatment areas in the shell are separated by horizontal partitions 6, vertical partitions I15 and vertical partitions II16 constitute. The horizontal partition 6 is located at the middle and lower positions in the housing, and divides the housing into upper and lower parts. Holes are evenly distributed on the horizontal dividing plate 6, which is a perforated dividing plate, and the aperture of the hole on the horizontal dividing plate 6 is not greater than the particle size of the mobile packing 7 in the mobile packing area. The vertical partition I15 is located at the center of a pair of sides of the housing. From the upper end of the housing to above the bottom of the housing, t...

Abstract

Upward flow combined type secondary biological film sewage treatment integrated equipment comprises a shell body and seven processing zones in the shell body, wherein the seven processing zones are defined by horizontal partition boards and vertical partition boards, holes are evenly distributed on each horizontal partition board, two spaces below the horizontal partition boards are filled with fixed packing to serve as anoxic zones, two sludge suspension zones are arranged on the bottom portions of the horizontal partition boards, two spaces above the horizontal partition bards are filled with movable packing to serve as aerobic zones, sewage enters through a bottom water inlet branch pipe into the anoxic zones and the aerobic zones to be processed after two times of upward flowing and finally flows into solid and liquid separating zones defined by the vertical partition boards, and then purification of organic sewage is accomplished. The equipment has the advantages that anaerobic treatment, aerobic treatment, anaerobic treatment and aerobic treatment are sequentially conducted on sewage, water is finally discharged after passing through the solid and liquid separating zones, and therefore the processing effect is good; the structure is compact, occupied space is small, and maintenance and management are facilitated; the upward flow and plug flow method is adopted, and energy is saved; the service life of the packing is long, oxygenating performance is good, biofilm culturing is fast, biofilm stripping is easy, and high-load impact resistance is good.

Description

technical field [0001] The invention belongs to the technical field of sewage purification, in particular to equipment for treating various organic sewage. Background technique [0002] Sewage treatment is one of the key tasks of environmental protection. my country's large cities have centralized sewage treatment facilities to a certain extent, but most small and medium-sized towns basically have no sewage treatment facilities, resulting in a large amount of sewage being directly discharged into water bodies without treatment, causing local water environment pollution. my country's sewage treatment tasks are very heavy, so it is necessary to build and transform a large number of sewage treatment facilities to treat sewage. Most of the sewage treatment facilities in the prior art are facilities with plane flow. Its disadvantage is that it occupies a large area. Contents of the invention [0003] The purpose of the present invention is to provide a sewage treatment equip...
