Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a multi-carbon source dosing device for wastewater treatment. Background Technology

[0002] In today's world, where environmental protection is receiving increasing attention, wastewater treatment, as a crucial link in water resource recycling and environmental protection, has become a focus of continuous attention within the industry in terms of technological innovation and efficiency improvement. During wastewater treatment, to improve the efficiency of biological treatment, especially for wastewater with low carbon sources or recalcitrant organic matter, it is usually necessary to add additional carbon sources such as sodium acetate, glucose, starch, and fermentation-type compound carbon sources to supplement the nutrients needed by microorganisms, promote their growth and metabolic activities, and thus accelerate the decomposition of organic pollutants. This step is of great significance for improving effluent quality, reducing residual sludge, and lowering overall operating costs.

[0003] Traditional carbon source addition methods often employ a single strategy, failing to adapt flexibly to varying water quality conditions and treatment requirements. This uniformity not only limits the improvement of treatment effectiveness but also increases operational complexity and uncertainty.

[0004] Furthermore, traditional carbon source dosing methods often rely on manual operation, involving manual metering and pouring. This method is not only labor-intensive but also makes it difficult to ensure precise control of the dosage. Inaccurate dosage can lead to poor treatment results, and overdosing can increase operating costs and even cause secondary pollution problems such as eutrophication. Therefore, there is an urgent need to design a multi-carbon source dosing device for wastewater treatment to solve these problems. Utility Model Content

In addition, the storage box 26 is fixedly connected to the top of the frame 1 by welding and is used to store the material to be fed. The material can fall naturally to the feeding wheel 24 by gravity.

[0035] In this embodiment, a stretching mechanism 3 is provided inside the metering mechanism 2. The stretching mechanism 3 is used to adjust the size of the slot of the metering mechanism 2.

[0036] Specifically, the tensioning mechanism 3 includes several telescopic plates 31, and a handle 32 is fixedly connected to one side of each telescopic plate 31.

[0037] A hollow guide block 33 is fixedly connected to one side of the bottom of the telescopic plate 31. A connecting rod 34 is provided inside the guide block 33. An operating lever 35 is fixedly connected to the outer wall of the connecting rod 34. A slider 37 that extends through the outside of the guide block 33 is fixedly connected to one end of the connecting rod 34. A spring 36 is sleeved on the outer wall of the connecting rod 34. The main function of the stretching mechanism 3 is to adjust the size of the slot of the quantitative mechanism 2, thereby achieving further precise control of the material feeding amount.
