Description
TECHNICAL FIELD
[0001] The utility model belongs to sewage treatment technical field relates to a kind of active sand filter tank anti-blocking auxiliary aeration device. BACKGROUND
[0002] In the field of sewage treatment, active sand filtration is one of the commonly used methods. Typically, the active sand treatment unit of a sewage treatment plant is used to receive wastewater after flocculation and sedimentation in the sewage plant. The main purpose is to remove suspended matter in the wastewater. Through the filtering action of sand, suspended matter in the wastewater is separated to ensure that the normal wastewater effluent enters the next unit.
[0003] Because in actual sewage treatment, the sewage treatment plant has a Fenton treatment process and adds PAM reagent to the wastewater before the sand filtration unit, which can cause the wastewater to contain a large amount of suspended matter and ferric oxide. Ferric oxide is a reddish-brown powder commonly known as iron red, which can easily form a hard mass with the sand in the sand filter tank, resulting in poor sand lifting and sand reversing effect of the sand filter tank. SUMMARY
[0004] The utility model aims at solving the above problems, and provides an active sand filter tank anti-blocking auxiliary aeration device.
[0005] To achieve the above-mentioned purpose, the utility model provides an active sand filter tank anti-blocking auxiliary aeration device, which comprises a gas supply frame and an aeration pipe detachably connected to the gas supply frame.
[0006] The gas supply frame comprises a first pipe, a second pipe, a third pipe and a fourth pipe. The first pipe and the second pipe are connected by a first connection tee. The second pipe and the third pipe are connected by a second connection tee. The third pipe and the fourth pipe are connected by a third connection tee. The fourth pipe and the first pipe are connected by a fourth connection tee.
[0007] Further, the first connection tee, the second connection tee, the third connection tee and the fourth connection tee are respectively connected to the aeration pipe.
[0008] Further, the first pipe comprises a first part and a second part, and the first part and the second part are connected by a fifth connection tee.
[0009] Further, the third pipe comprises a third part and a fourth part, and the third part and the fourth part are connected by a sixth connection tee.
[0010] The utility model has the following advantages:
[0011] The active sand filter tank anti-blocking auxiliary aeration device has the advantages that the four D20 aeration pipes are located at the four positions around the sand lifting structure, the hardened sand is opened through aeration, and the sand lifting effect of the sand filter tank is enhanced.
