Problems solved by technology

[0003] Ordinary aeration tanks can increase the working efficiency of the overall device by increasing the contact time between sewage or sludge and air. However, since sewage treatment includes multiple operating processes, the sewage or sludge treated with aeration needs to be further processed. The sedimentation and filtration operations are relatively cumbersome, and the aeration process itself requires a lot of time. At the same time, the sedimentation, separation, and sterilization operations are performed. The multi-step operation process takes time, resulting in a long operating time for the overall process, which ultimately affects Sewage or sludge treatment efficiency

Embodiment 1

[0017] Embodiment 1: as figure 1 and 2 Shown is a multifunctional sludge treatment aeration tank, the aeration tank is a rectangular tank body 1, the middle part of the tank body 1 is provided with a horizontal separation screen 2, the separation The screen 2 divides the pool body 1 into a sewage area 3 and a sludge area 4, and the two ends of the pool body 1 are respectively provided with a feed port 9 and a discharge port 10-1, 10-2, and the feed port 9 Between the discharge port 10-1 and 10-2, a primary processing device 5, a secondary processing device 6, a tertiary processing device 7 and a fourth processing device 8 are successively arranged, and the primary processing device 5 is a vertical stirring Paddle, the secondary treatment device 6 is a horizontal stirring paddle, the three-stage processing device is a ventilation ring 7, the fourth-stage processing device is a T-type sterilization table 8, and the vertical stirring paddle 5 and horizontal stirring paddles 6 a...

Embodiment 2

[0018] Embodiment 2: as figure 1 and 2 As shown, the discharge port of the present invention includes a sludge discharge port 10-2 and a sewage discharge port 10-1, and the sludge discharge port 10-2 is arranged at the bottom of the sludge area 4, so The above-mentioned sewage discharge port 10-1 is set above the sewage area 3, and the sludge and sewage are respectively discharged through the sludge discharge port 10-2 and the sewage discharge port 10-1, thereby completing the preliminary separation of sludge and sewage Easy to operate and optimize the overall production line.

Embodiment 3

[0019] Embodiment 3: as figure 1 and 2 As shown, the first-level treatment device 5, the second-level treatment device 6, the third-level treatment device 7 and the fourth-level treatment device 8 of the present invention are evenly distributed in the pool body 1, and the distance between two adjacent devices is The same; the four sets of treatment devices 5, 6, 7, and 8 are used to treat sludge and sewage in different ways. In order to avoid the influence of different treatment devices, there is a certain installation distance between the four devices, which is convenient for unification planning and management.

Abstract

The invention discloses a multifunctional sludge treatment aeration tank. A separation screen horizontally arranged is arranged in the middle of an aeration tank body, and the tank body is divided into a sewage area and a sludge area through the separation screen. A feeding port and a discharging port are formed in the two ends of the tank body respectively. A first-level treatment device, a second-level treatment device, a third-level treatment device and a fourth-level treatment device are arranged between the feeding port and the discharging port in sequence. The first-level processing device is a perpendicular stirring paddle, the second-level treatment device is a transverse stirring paddle, the third-level treatment device is a ventilation ring, and the fourth-level treatment device is a T-shaped sterilization table. The perpendicular stirring paddle and the transverse stirring paddle are arranged in the sludge area. According to the multifunctional sludge treatment aeration tank, due to the combined action of the four sets of treatment devices and the separation screen, aeration of sewage and sludge can be completed in the aeration tank, meanwhile, primary separation operation and sterilization operation of sludge and sewage are completed, sludge and sewage are conveniently treated respectively, and the production technology for sewage and sludge is optimized.

Description

technical field [0001] The invention relates to the field of sewage and sludge treatment technology, in particular to a multifunctional aeration tank for sewage and sludge treatment. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. [0003] Ordinary aeration tanks can increase the working efficiency of the overall device by increasing the contact time between sewage or sludge and air. However, since sewage treatment includes multiple operating processes, the sewage or sludge treated with aeration needs to be further processed. The sedimentation and filtration operations are relatively cumbersome,...
