Embodiment 1
[0024] A kind of office sewage comprehensive treatment device of the present embodiment, as figure 1 and figure 2 As shown, it mainly includes a circular pool body 1, and a circular biological purification pool 2 is separately provided at the inner center of the circular pool body 1. The circular biological purification pool 2 is an open setting with an opening at the top, and a circular biological purification pool 2 The pool wall of the shaped biological purification pool 2 is higher than the outer wall of the circular pool body 1, and an annular treatment zone 3 is formed between the circular biological purification pool 2 and the circular pool body 1. The annular treatment belt 3 is a closed arrangement, and its upper cover is connected to the outside of the circular biological purification tank 2 pool wall. The annular processing belt 3 is provided with four partitions 4 at a central angle of 90°, and the partitions 4 are structures that completely divide the annular pr...
Embodiment 2
[0029] This embodiment is further defined on the basis of the above-mentioned embodiments, the filler includes an arc-shaped filler frame 8 arranged in the anaerobic zone 7, arranged in the primary aeration tank 302 and the secondary aeration tank 304 The multi-faceted hollow ball packing 9 and the combined packing 10 arranged in the secondary anaerobic zone 7. The arc-shaped filler frame 8 is a plurality of arc-shaped frame structures arranged vertically side by side, and its radian is consistent with the annular processing belt 3. On each arc-shaped frame body, a plurality of long rods are vertically arranged side by side. Each long rod is sleeved with a plurality of packing discs, and the arc-shaped packing rack 8 can adapt to the structural characteristics of the annular processing belt, improve the space utilization efficiency, and increase the biofilm loading capacity at the same time. The structure of the combined packing 10 is to change the plastic disc buckle into a d...
Embodiment 3
[0031] This embodiment is further defined on the basis of the above embodiments, the secondary aeration tank 304 is provided with a baffle B that divides the secondary aeration tank 304 into an aeration zone 11 and a disinfection zone 12, so The aeration zone 11 is in communication with the secondary anoxic tank 303, the disinfection zone 12 is in communication with the circular biological purification tank 2, and a UV lamp disinfection device is arranged in the disinfection zone 12. The baffle B is the same as the baffle A, both of which are fixed on the ring-shaped treatment belt 3 at the bottom and both sides, with a channel left on the upper part, and the aeration device is arranged at the bottom of the aeration zone 11, and the disinfection goes The built-in UV lamp disinfection device sterilizes and disinfects through ultraviolet radiation, thereby reducing the E. coli index in the sewage. Other parts of this embodiment are the same as those of the foregoing embodiment, ...
