Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a carbon source precise dosing device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a water body or reuse. This process usually includes three stages: physical treatment, chemical treatment and biological treatment. It aims to remove or reduce harmful substances in wastewater so that it meets national or local emission standards, thereby protecting the environment and human health. Carbon source is an important nutrient for the growth of microorganisms. Adding an appropriate amount of carbon source to wastewater through precise dosing devices can promote the growth and metabolic activity of microorganisms, thereby accelerating the degradation of organic matter and improving wastewater treatment efficiency.

[0003] The existing Chinese patent with announcement number CN220579040U discloses a carbon source dosing device, including: a hollow carbon source storage tank, a dosing port is arranged on the upper surface of the carbon source storage tank, a carbon source suction mechanism is arranged on the carbon source storage tank, and a liquid outlet pipe is connected to the output port of the carbon source suction mechanism; a dispersion cylinder connected to one end of the liquid outlet pipe, a liquid outlet groove is opened on the lower surface of the dispersion cylinder, a stirring dispersion component is arranged in the inner cavity of the dispersion cylinder, and the liquid outlet pipe is connected to the inner cavity of the dispersion cylinder.

[0004] Although the above scheme can make the carbon source be quickly and evenly dispersed into the sewage and avoid the concentration of carbon source in the sewage, the amount of carbon source added is not a fixed value due to the different types of carbon sources and the different water quality of sewage. The device is not easy to control the addition of carbon source, which affects the effect of sewage treatment. At the same time, the solid powdered carbon source is not fully dissolved, and carbon source may clump in the carbon source storage tank, affecting the effect of sewage treatment. Therefore, it does not meet the existing needs. In this regard, we propose a precise carbon source dosing device for sewage treatment. Utility Model Content
