Embodiment 1

[0016] An embodiment of the present invention shown in Figure 1 is provided with a multifunctional area 1, an aerobic area 5, a partition wall 2, a partition wall 4, a transition area 3, a water inlet pipe 6, a return suction port 7 and an outer mud discharge Suction port 8. Near the bottom of the multi-functional area 1 is provided with the same aeration device as the aerobic area 5, including an air supply pipe 13 and an aeration head 14; As shown in Fig. 1, Fig. 3 and Fig. 4, some small holes 9 are respectively offered in the middle and upper parts of the A partition wall 2 and the B partition wall 4; a row of square holes 11 are respectively offered at the bottom thereof; two large holes 10 are respectively offered at the bottom thereof , and communicate with the connecting pipe 17. The bottom straight outlet of the water inlet pipe 6 is closed, and a plurality of water outlets 12 are arranged on its side wall. As shown in Figure 2, a stirring system consisting of four s...

Embodiment 2

[0020] Shown in Fig. 5 is the transformation of the present invention to a kind of SBR reaction pool that has been operated, and former anaerobic zone is transformed into multifunctional zone 1, and aerobic zone 5 remains unchanged, wherein the volume of multifunctional zone is 675m 3 , the volume of the aerobic zone is 2780m 3 . In the multifunctional area 1, an air supply pipe 13 and an aeration head 14 are added according to the standard of the aerobic area 5; Three rows of 21 φ160mm small holes 9 are set on the middle and upper part of the A partition wall between the multi-functional area 1 and the aerobic area 5, and the water flow of each row of small holes 9 is 100m 3 / h or so, keep the water flow unimpeded, and at the same time prevent the sludge disturbance caused by the supernatant flow rate too fast; open 6 square holes of 500×500mm at the bottom of the A partition wall 2 to ensure the water inflow of each batch is 1400m 3 / h, can pass through smoothly in a short...

Abstract

The present invention is one multifunctional sewage treating reaction tank. The multifunctional sewage treating reaction tank includes multifunctional area with air supplying pipe and aerating heads similar those in an aeration area. The multifunctional area may be used as aeration area, facultative area or anaerobic area optionally based on the inlet water quality. The present invention has greatly raised sewage treating capacity and lowered comprehensive sewage treating cost.

Description

technical field [0001] The invention belongs to a sewage treatment device, in particular to a multifunctional reaction pool for urban comprehensive sewage treatment. Background technique [0002] Water is a precious but very scarce resource. If urban sewage is discharged randomly without treatment, it will inevitably cause water pollution, deteriorate the environment, affect people's daily life, and even endanger life and health. Urban comprehensive sewage generally includes residential sewage and industrial sewage discharged after primary treatment in factories. The treatment of urban comprehensive sewage usually adopts biochemical technology. SBR is one of the wastewater treatment technologies that uses microorganisms to operate intermittently in a certain time sequence in the reactor. Its principle is different from the traditional activated sludge method in that the wastewater concentration gradient is large during the reaction process. Keep...
