Embodiment 1

[0025] Embodiment 1, combining figure 1 with figure 2 A kind of urban domestic sewage reflux treatment device of the present invention is described in further detail:

[0026] An urban domestic sewage reflux treatment device, comprising a water inlet valve well 1, a regulating tank 2 and a water distribution well 3 connected in sequence through pipelines, domestic sewage enters the water inlet valve well 1 through the urban domestic sewage pipeline, and the water inlet valve well 1 There is a coarse grid 11 inside, and the coarse grid 11 is used as a pretreatment unit to reduce the workload of the subsequent processing unit; domestic sewage enters the water inlet valve well and after simple treatment, the working unit of the lifting pump room will work to lift the domestic sewage to the regulating level. In the pool 2, two groups of fine grids 21 are arranged in the regulating pool 2, and the two groups of fine grids 21 are arranged in parallel, and the domestic sewage is se...

Embodiment 2

[0027] Embodiment 2, the nitrifying liquid return well 44 is returned to the front end of the anoxic pool 41 according to the ratio of 50% to 100% of the domestic sewage in the aerobic pool to improve the denitrification efficiency of the system.

[0028] The anoxic tank 41 , the anaerobic tank 42 and the aerobic tank 43 are all equipped with a stirring device 45 , and the stirring device 45 includes a stirring shaft and a stirring blade.

[0029] Described aerobic tank 43 is connected with aeration system 46, and described aeration system 46 comprises aeration tank body 461, stuffing box 462, water inlet 463, water outlet 464, air pressurized pump 465, and described stuffing box 462 passes through The packing pipe is connected with the aeration tank 461, the stuffing box 462 is filled with activated sludge, the air booster pump 465 is set at the bottom of the aeration tank 461, and the water inlet 463 is set at the aeration tank 461 The water outlet 464 is set at the bottom o...

Embodiment 3

[0030] Embodiment 3, combining image 3, the ammonia nitrogen on-line measurement device 431 and the pH value on-line measurement device 432 are installed in the aerobic pool 43, the aerobic pool 43 is also connected to an alkali solution tank 433, the water inlet pipe 434 of the aerobic pool 43 and the inlet The lye pipeline 435 is provided with a solenoid valve, and the water inlet pipeline 434 of the aerobic tank is laid on the bottom of the aerobic tank 43 . The ammonia nitrogen online measuring device 431 installed in the aerobic pool 43 is used to control the opening and closing of the aerobic pool 43 water inlet pipeline 434 electromagnetic valve, when the ammonia nitrogen value of domestic sewage in the aerobic pool 43 is lower than the set value The aerobic pool inlet pipeline 434 solenoid valves were opened during the lower limit, and when the ammonia nitrogen value of domestic sewage in the aerobic pool 43 was higher than the upper limit of the set value, the aerobi...

Abstract

The invention discloses a municipal domestic wastewater refluxing treatment device which comprises a water inlet valve chamber, a regulating reservoir and a distribution well connected in sequence byvirtue of pipelines, wherein the distribution well is connected with a nitrogen and phosphorus removal unit of domestic wastewater; the nitrogen and phosphorus removal unit comprises an anoxic pond, an anaerobic pool and an aerobic tank; the anoxic pond, the anaerobic pool and the aerobic tank are connected in sequence by virtue of pipelines; the anoxic pond, the anaerobic pool and the aerobic tank are divided into two groups; the distribution well respectively enters the anoxic pond, the anaerobic pool and the aerobic tank via branch pipes; the domestic wastewater enters an inlet well after passing through the anoxic pond, the anaerobic pool and the aerobic tank, and one part of the wastewater enters a nitrification liquid backflow well, the nitrification liquid ascends and flows back tothe front end of the anoxic pond by virtue of the nitrification liquid backflow pipe, and the domestic wastewater enters a secondary sedimentation tank after passing through a contact flocculation basin; the wastewater entering the secondary sedimentation tank is divided into two parts, one part enters a sludge return well, and the other part of the domestic wastewater enters an effluent well. Theproblems that an urban sewage technology lags and the wastewater treatment rate is low are solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban domestic sewage backflow treatment device. Background technique [0002] Water is the source of life and the indispensable foundation of all things. The United Nations has set the theme of the ten-year development from 2005 to 2015 as "Water for Life". Since the reform and opening up, my country has undergone earth-shaking changes, the economy has flourished, and the country's soft and hard power have been recognized by the world. With the sound and rapid development of the national economy, environmental problems are increasingly emerging and have become an important factor restricting my country's economic development. The repeated appearance of words such as "water environment pollution" and "water crisis" makes us realize that water pollution is in the Around you, you can't ignore it, let alone ignore it. [0003] The scale of urbanization in my country has...
