Example Embodiment

[0038] Specific embodiment 1: This embodiment provides an air pump driven sewage reactor based on program control, such as Figure 1-5 As shown, the air pump-driven sewage reactor includes an inlet pipe 1, a sewage treatment reactor 2, a PLC control cabinet 3, and an outlet pipe 9, wherein:

[0039] The PLC control cabinet 3 has a built-in air pump and a PLC controller. The operation of the air pump is controlled by the PLC controller program. The air pump is divided into 4 air pipes, namely the first air lift pipe 4, the second air lift pipe 5 and the third air lifter. The solenoid valve is arranged between the pipe 6 and the aeration pipe 7, the air pump and the first air lifting pipe 4, the second air lifting pipe 5, the third air lifting pipe 6 and the aeration pipe 7. The opening of the air lift pipe 5, the third air lift pipe 6 and the aeration pipe 7 is implemented by a PLC controlled solenoid valve. The working principle diagram of the first stripping tube 4, the second ...

Example Embodiment

[0056] Specific embodiment 2: This embodiment provides a process for treating rural sewage by using the air pump to drive the sewage treatment reactor described in the first embodiment, such as Image 6 As shown, domestic sewage containing feces first enters the first section of the septic tank, solids precipitate in the first section, and the sewage enters the air pump at the end of the septic tank to drive the sewage treatment reactor.

[0057] The installation diagram of the septic tank and the air pump driving the rural sewage treatment reactor is as follows Figure 7 As shown, the villagers' drainage and feces enter the septic tank, the effluent of the septic tank is connected to an air pump to drive the sewage treatment reactor, and the effluent of the sewage treatment reactor is disinfected and air stripped, and the effluent is discharged or reused. The sewage treatment reactor is connected with 3 air stripping pipes and 1 aeration pipe. These 4 air stripping pipes are conne...

Example Embodiment

[0058] Embodiment 3: In this embodiment, the sewage treatment reactor has a diameter of 1.5m, a height of 2.6m, and the volume ratio of the water inlet zone, the main reaction zone and the disinfection outlet zone is 2:3:1, and the operating effect is: Influent COD312 ~342mg / L, effluent COD: 43.2~49.2mg / L; influent ammonia nitrogen 55~61 effluent mg / L, effluent ammonia nitrogen 0.9~1.3mg / L, influent total nitrogen 38~46mg / L, effluent total nitrogen 14.3~ 18.7mg / L, total phosphorus in influent 4.06~5.29 mg / L, total phosphorus in effluent 1.39~2.48 mg / L, sludge concentration in main reaction zone: 3573~4300mg / L.

Abstract

The invention discloses an air pump driven sewage reactor based on program control, and a treatment method thereof. The air pump driven sewage reactor comprises a water inlet tube, a sewage treatmentreactor, a PLC control cabinet and a water outlet tube, wherein an air pump and a PLC are arranged in the PLC control cabinet; the air pump is divided into a first air lifting tube, a second air lifting tube, a third air lifting tube and an aeration tube from the PLC control cabinet, and each air pipeline is opened by a PLC controlled solenoid valve; the sewage treatment reactor comprises an innercylinder and an outer cylinder, the inner cylinder is provided with a outlet water disinfecting zone, and the outer cylinder is divided into a water inlet zone and a main reaction zone by a partitionplate; a high liquid level gauge, a low liquid level gauge and the first air lifting tube are arranged in the water inlet zone; a bio-filler, the second air lifting tube and the aeration tube are arranged in the main reaction zone; a disinfecting tablet basket and the third air lifting tube are arranged in the outlet water disinfecting zone; and the water inlet tube is connected with effluent water from a septic tank, and is connected with the water inlet zone. The technical requirement of near zero maintenance of a small volume of sewage is met in the invention.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a sewage treatment device and a treatment method for a single household and adjacent multi-household villages with a small amount of water, in particular to an air pump-driven one-gas multi-purpose sewage treatment device and a treatment method. Background technique [0002] With the rapid development of my country's economy, the income of rural residents has increased significantly, and people have put forward higher requirements for the living environment. The problem of rural surface and groundwater pollution caused by scattered sewage has attracted much attention. It is urgent to collect and clean rural sewage. deal with. [0003] At present, in the treatment of urban domestic sewage in my country, the traditional anaerobic-anoxic-aerobic (commonly known as AAO) process and circulating activated sludge (commonly known as CASS) process are mostly used to remove organic m...
