In addition, compared with the mode of simply increasing the specification of a single set of equipment, the size of each part can be smaller, and the transportation is convenient.
The embodiment of the utility model provides a combined type sewage treatment device, which comprises: a housing 9;
each functional area of each sewage treatment subsection is arranged in the housing 9. This scheme is the integrative structure of sewage treatment of high integration promptly.
Furthermore, the plurality of sewage treatment subsections are symmetrically arranged around the center of the shell 9, so that the structure is reasonable, the installation and maintenance are convenient, and the interchangeability is realized.
Due to the limitation of the pipe diameter and the process length, the number of the sewage treatment subsections can be two;
the two biological reaction areas I are both positioned in the middle of the shell 9 in the horizontal direction, and the biological reaction areas I are water inlet end functional areas of the sewage treatment subsection; so as to be convenient for centralized water inflow in the middle part;
the water outlet end functional areas of the two sewage treatment subsections are respectively positioned at two ends of the shell 9 in the horizontal direction and can respectively discharge water or finally converge at a water outlet. The structure of which can be seen in fig. 1a, 1b, 2a and 2 b.
Specifically, a middle partition plate is arranged between the two biological reaction zones I in the shell 9. Namely, the two sewage treatment branches share the structure, and the structure is more compact.
Considering that the pressure born by the middle partition plate is larger when the two sides of the equipment are arranged, in order to further optimize the technical scheme, the thickness of the middle partition plate is larger than that of the partition plate of each functional area in each sewage treatment subsection.
In this embodiment, each sewage treatment branch further includes: a water inlet pipe 1 and a water outlet pipe 7;
the water inlet pipe 1 is arranged at the top of the shell 9 and is communicated with the biological reaction zone I; the water outlet pipe 7 is arranged at the end part of the shell 9 and is communicated with the water outlet end functional area. The top is adopted for water inlet, and the side is adopted for water outlet, so that the device is suitable for buried installation; the water inlet pipe 1 is convenient to disassemble, assemble and maintain, and the flowmeter and other small parts are convenient to install, overhaul and watch.
Furthermore, the water outlet pipe 7 is communicated with the high position of the sedimentation zone III.
Or, a plurality of functional areas of each sewage treatment subsection also comprise: a mixing zone IV, a flocculation zone V and a phosphorus removal zone VI which are sequentially connected behind the precipitation zone III; the water outlet pipe 7 is communicated with the high position of the phosphorus removal area VI. By the arrangement, the water outlet pipe 7 is communicated with the high position of the water outlet end functional area, so that the settling time of the corresponding water outlet end functional area can be prolonged, and floating objects are prevented from being taken away from the box body.
Fig. 1a and 1b are schematic diagrams of symmetrical composite design equipment with effluent as a primary standard A and a primary standard A. When the effluent of the equipment is of a secondary standard and a tertiary standard, the equipment does not have three functional regions of IV, V and VI, namely a dephosphorization process and a subsequent secondary precipitation process, as shown in fig. 2a and 2 b.
Preferably, each sewage treatment branch further comprises: a breather pipe 2;

each sewage treatment subsection also includes: and the dosing pipe 6 is communicated with the mixing area IV.
At present, the sludge reflux of the sewage treatment equipment adopts the power reflux of a pump, so that the energy consumption is increased. In order to solve the problem, the scheme is that a mud sliding plate which inclines towards the biological reaction zone I is arranged at the bottom of the sedimentation zone III; the sludge in the settling zone III flows back in a gravity-gravity flow mode and enters the biological reaction zone I through a slip plate;
each sewage treatment subsection also includes: a perforated sludge discharge pipe 8 arranged on the side wall (corresponding to the biological reaction zone I) of the shell 9; namely, the mixed liquid refluxed from the precipitation zone III is discharged through the biological reaction zone I. So set up, the backward flow of this liquid path design does not rely on the power of water pump, and activated sludge flows back to biological reaction district I through gravity automatically, and energy saving consumes, and reduces fortune dimension intensity. In view of the fact that the water inlet ends of the two biological reaction zones I share the middle partition plate, the corresponding perforated sludge discharge pipes 8 need to be arranged on the side wall, such as the upper side wall in fig. 1b, in an avoiding manner, and the axial directions of the perforated sludge discharge pipes 8 are perpendicular to the liquid flowing direction of each functional zone.
Preferably, the inclination angle of the mud sliding plate is more than or equal to 45 degrees, and a better mud self-weight backflow effect can be realized.
The solution is further described below in connection with a second embodiment:
the application provides a tubular equipment of symmetrical composite design, buries formula installation generally, also can ground the formula installation. When the inflow is large (the treatment scale is more than or equal to 72t/d, because when the inflow is too large, because the inclined angle of the sliding mud plate in the sedimentation area needs to be kept more than or equal to 45 degrees, if the inclined angle of the sliding mud plate in the sedimentation area is too small when the inclined angle of the sliding mud plate in the sedimentation area is arranged on one side, the sludge is not beneficial to the backflow of the sludge, and therefore, when the inflow is large, the pipe type JBR is arranged on two sides, the equipment arrangement and the equipment quantity on each side are the same, the inflow water is uniformly distributed on two sides, and the outflow water on the last two sides can be respectively or finally converge at a water outlet. When the water consumption of residents is low at a certain time, the residents can independently use the equipment on one side to feed water to treat sewage, so that a large amount of energy consumption can be reduced.
The equipment is arranged on two sides and can be transported in two parts, so that the equipment is prevented from being too long in length during transportation, and the transportation is facilitated.
The two sides of the device are arranged, the pressure born by the middle partition plate is larger, and the thickness of the middle partition plate is larger than that of other partition plates (except a mud sliding plate in a settling area, the middle partition plate is also a bearing plate).
The two sides of the device are arranged, the two sides of the perforated sludge discharge pipe 8 of the biological reaction zone I are respectively arranged, the two sides of the perforated sludge discharge pipe 8 of the dephosphorization zone VI are also arranged, and the two perforated sludge discharge pipes 8 are axially vertical.
