Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated carbon source dosing device for an A0 pool process. Background Art

[0002] The A0 tank process is a common wastewater treatment process, where "A" stands for anaerobic and "O" for aerobic. In the A0 process, wastewater first enters the anaerobic tank. Under anaerobic conditions, anaerobic bacteria break down large organic molecules in the wastewater into smaller ones, releasing phosphorus. The wastewater then enters the aerobic tank. In the aerobic environment, aerobic bacteria further decompose the organic matter and absorb phosphorus, converting it into phosphate-accumulating bacteria. Phosphorus removal is achieved by discharging excess sludge. During wastewater treatment, an external carbon source is required to ensure that the effluent total nitrogen content meets standards and maintain microbial activity. Currently, a variety of carbon sources are available, including methanol and flour. Solid carbon sources such as glucose and flour are commonly used. During use, the carbon source is introduced into the wastewater treatment unit using an integrated dosing device.

[0003] A Chinese patent (authorization announcement number: CN221166272U, authorization announcement date: 2024-06-18) proposes a new carbon source dosing device, including a carbon source agent tank and an end cover, wherein the top of the carbon source agent tank is provided with an end cover, the bottom end of the end cover is fixed with a sealing ring, a first through hole is provided at the middle position of the top end of the end cover, a liquid collection tube is provided inside the first through hole, and an adjustment structure is fixed to the top end of the end cover outside the liquid collection tube, and the adjustment structure includes a mounting seat, a screw, a support plate, a second through hole, a support frame and a screw sleeve.

[0004] In response to this disclosed technology, in the existing integrated carbon source dosing device, the solid carbon source first needs to be dissolved in water in the dissolving tank so that the carbon source and water are fully mixed, and then quantitatively transported to the sewage treatment structure through a metering pump to treat the sewage. However, the dissolving tank is a sealed design. When the carbon source is mixed and dissolved inside the dissolving tank, the dissolution situation inside the dissolving tank is not convenient to observe. If the solid carbon source is not fully dissolved, after being transported to the sewage by the metering pump, there will be an error in the proportion of carbon source input, which will affect the sewage treatment effect. For this reason, we propose a carbon source integrated dosing device for the A0 pool process. Utility Model Content
