Problems solved by technology

[0003] However, in the existing technologies, there are few that can directly carry out small-scale sewage treatment and the effluent meets the recycling standard. They are usually large-scale sewage treatment equipment, and a set of complicated treatment processes are used for treatment, which not only occupies a large area, but also Moreover, outdoor installation will generate a large amount of malodorous gas, so it cannot be installed in residential areas or commercial office areas with many people
However, the sewage generated in the general commercial office area is mainly the discharge water produced by washing water and toilet water, and most of them are non-toxic inorganic salts. Domestic sewage contains a lot of nitrogen, phosphorus, and sulfur, and there are many pathogenic bacteria. The small-scale regional sewage treatment devices in the existing technology are not able to treat nitrogen-containing and phosphorus-containing sewage well, resulting in the treated sewage not being able to enter the sewage circulation system

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, ...

Abstract

The invention discloses a comprehensive treatment device for office building sewage. The device comprises a circular tank, wherein a circular biological purification tank concentric with the circular tank is arranged in the circular tank, a sealed annular treatment zone is formed between the outer wall of the circular biological purification tank and the inner wall of the circular tank, and the annular treatment zone is filled with a stuffing; four division plates for dividing the annular treatment zone into a primary anaerobic tank, a primary aeration tank, a secondary anoxic tank and a secondary aeration tank in sequence are further arranged in the annular treatment zone; and through a lift pump system, the primary anaerobic tank is communicated with the primary aeration tank, the primary aeration tank is communicated with the secondary anoxic tank, the secondary anoxic tank is communicated with the secondary aeration tank, and the secondary aeration tank is communicated with the circular biological purification tank. The comprehensive treatment device is novel in structure, occupies a small area, can efficiently and comprehensively treat sewage, and can be arranged in a residential area or a commercial office area.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a comprehensive sewage treatment device for office buildings. Background technique [0002] In modern urban planning and design, urban sewage is generally collected and treated in a centralized manner, and the sewage is discharged into the urban sewer system regardless of whether it is a residential area or a commercial area. Generally, in rural areas or industrial areas, the sewage indicators produced are characteristic, while urban sewage has certain differences in different regions. Now, accurate sewage collection, treatment and recycling in different regions can greatly improve the efficiency of sewage treatment and save Water resources, improve the utilization rate of waste water. [0003] However, in the existing technologies, there are few that can directly carry out small-scale sewage treatment and the effluent meets the recycling standard. They are usually larg...
