Embodiment 1

[0023] Such as figure 1 Among them, an unattended township sewage treatment AAO integrated pool is characterized by: including anaerobic hydrolysis and acidification adjustment pool 1, anoxic denitrification pool 2, nitrification and aerobic aeration pool 3, suspension clarification pool 4 and inclined pipes The sedimentation tank 5, the anaerobic hydrolysis acidification regulating tank 1 is connected with the anoxic denitrification tank 2, the anoxic denitrification tank 2 is connected with the nitrification aerobic aeration tank 3, the nitrification aerobic aeration tank 3 is connected with the suspension clarification tank 4 is connected, and the suspended clarifier 4 is connected with the inclined tube sedimentation tank 5;

[0024] One side of the inclined tube sedimentation tank 5 is provided with a contact disinfection channel 6 and a pasteurized metering tank 7, the contact disinfection channel 6 communicates with the inclined tube sedimentation tank 5, and the pasteu...

Embodiment 2

[0030] The anoxic denitrification tank 2 described on the basis of embodiment 1 is provided with a water inlet channel 14 connected to the water collection port 13, and two diagonal positions at the bottom of the anoxic denitrification tank 2 are provided with two A submerged flowmaker 15, the anoxic denitrification tank 2 is provided with a water hole 16 on the wall near the nitrification aerobic aeration tank 3.

[0031] The sludge is kept in suspension by continuous operation of the submersible thruster. However, according to the water volume, season, and water quality, the intermittent operation mode of the time controller (such as running for 15 minutes and stopping for 15 minutes) can be used to save power consumption.

[0032] In addition, the submersible flowmakers 15 are symmetrically arranged at the two corners of the anoxic denitrification pool 2, and vertical poles are arranged along the pool body. The submersible flowmakers 15 use guide chains to lift up and down ...

Embodiment 3

[0034] On the basis of Example 2, an aeration system 17 and a nitrification liquid return device 18 are provided in the nitrification aerobic aeration tank 3, and a nitrification liquid return channel 19 is provided on one side of the nitrification aerobic aeration tank 3 , the output end of the nitrification liquid backflow device 18 is set in the nitrification liquid backflow channel 19 .

[0035] The nitrifying aerobic aeration tank 3 is continuously fed with water, and the aeration system 17 in the tank is used to realize continuous aeration and continuous water discharge. The aeration volume can be controlled by the 4~20mA signal feedback of the DO meter installed in the tank to control the frequency conversion speed regulating device of the blower to adjust the air supply volume. The dissolved oxygen in the aerobic pool is adjusted by the frequency converter to adjust the air supply volume of the blower, and the dissolved oxygen is controlled at about 1.0-1.5mg / L. When ...

Abstract

An unattended rural sewage treatment AAO (anerobic-anoxic-oxic) integrated tank comprises an anerobic hydrolytic acidifying adjusting tank, an anoxic denitrifying tank, a nitrification aerobic aerating tank, a suspending clarifying tank and an oblique tube precipitating tank. The anerobic hydrolytic acidifying adjusting tank is communicated with the anoxic denitrifying tank; the anoxic denitrifying tank is communicated with the nitrification aerobic aerating tank; the nitrification aerobic aerating tank is communicated with the suspending clarifying tank; the suspending clarifying tank is communicated with the oblique tube precipitating tank; one side of the oblique tube precipitating tank is provided with a contact sterilization ditch and a Parshall metering tank; the contact sterilization ditch is communicated with the oblique tube precipitating tank; the Parshall metering tank is communicated with the contact sterilization ditch; the anerobic hydrolytic acidifying adjusting tank isprovided with an inflow pipeline; the Parshall metering tank is provided with an outflow pipeline. The unattended rural sewage treatment AAO integrated tank helps effectively solve the problem that domestic sewage mixed with rural domestic wastewater and little industrial wastewater has great changes in quality and quantity, so that water treatment is non-standard; continuous treatment of wastewater is achieved, the quality of discharged water is stable and standard, and the integrated tank herein occupies small area.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an unattended township sewage treatment AAO integrated pool. Background technique [0002] At present, my country's sewage treatment rate is still low, especially in township sewage, most of which are discharged into surrounding water bodies without any treatment, causing serious pollution of surface and underground water sources. With the promulgation of the national "Water Ten Measures", township sewage has attracted the attention of local governments in various places. However, the outstanding situation faced by township sewage treatment is that the quality and volume of sewage water vary greatly. The peak of sewage discharge in townships is in the morning and evening. In addition, the sewage produced by some township enterprises and small workshops cannot be effectively purified and treated, and is mixed into domestic sewage collection pipes, causing changes in sewag...
