Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, and in particular to a wastewater activated carbon graded adsorption treatment device. Background Technology
[0002] In the field of wastewater treatment, activated carbon adsorption technology has played an important role as a common method. However, with the continuous improvement of the requirements for wastewater treatment, traditional activated carbon adsorption technology has gradually revealed many limitations. Traditional activated carbon adsorption exhibits significant limitations when dealing with high-concentration wastewater. Due to the limited number of adsorption sites, activated carbon quickly reaches saturation during the treatment of high-concentration wastewater, thus becoming unable to effectively adsorb pollutants. This necessitates frequent replacement of the activated carbon material. Conversely, in low-concentration wastewater, activated carbon cannot fully utilize its adsorption potential, resulting in a large amount of activated carbon being discarded before reaching saturation, leading to substantial resource waste and rendering it impractical. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a wastewater activated carbon graded adsorption treatment device, which aims to improve the problem that activated carbon in the prior art quickly reaches saturation in high-concentration wastewater and needs to be replaced frequently, while it cannot be fully used in low-concentration wastewater, resulting in waste.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater activated carbon graded adsorption treatment device, comprising treatment tank D, treatment tank C, treatment tank B, and treatment tank A. A first, second, and third overweight separator are sequentially installed at the rear of treatment tanks D, C, and B. A pre-storage tank is installed on the right side of treatment tank A.

The outlet of the filter press is fixedly connected to an installation pipe, which is connected to the treatment tank C. The output of the treatment tank C is fixedly connected to a connecting pipe c, which is connected to a first overweight separator. The first overweight separator is connected to the treatment tank B via a first conveying pipe. The outlet of the treatment tank B is fixedly connected to a connecting pipe b, which is connected to a second overweight separator. The second overweight separator is connected to the treatment tank A via a second conveying pipe. The outlet of the treatment tank A is fixedly connected to a connecting pipe a, which is fixedly connected to a third overweight separator. The third overweight separator is connected to the pre-storage tank via a third conveying pipe.
[0005] As a further description of the above technical solution: A fresh sewage pipe is fixedly connected to the top of the treatment tank D.
[0006] As a further description of the above technical solution: An auxiliary pipe is installed on the right side of the pre-storage tank, and the pre-storage tank is connected to the MVR device through the auxiliary pipe.
[0007] As a further description of the above technical solution: The activated carbon water delivery assembly includes an activated carbon water pipe fixedly installed on the top of the treatment tank A. The activated carbon water pipe is connected to the third heavy-duty separator. The lower end of the third heavy-duty separator is connected to the treatment tank B through the third water supply pipe. The lower part of the second heavy-duty separator is connected to the treatment tank C through the second water supply pipe. The lower end of the first heavy-duty separator is connected to the treatment tank D through the first water supply pipe.

[0010] This utility model has the following beneficial effects: 1. In this utility model, the device achieves the gradient utilization of activated carbon through a graded treatment architecture consisting of treatment tanks D, C, B, and A, combined with a circulation system formed by heavy-duty separators one, two, and three and activated carbon water conveying components. This avoids the problem of activated carbon becoming saturated after a single use and its adsorption potential not being fully released in traditional processes. It maximizes the adsorption capacity of activated carbon, significantly reduces the amount of activated carbon used, and lowers the resource consumption cost in the wastewater treatment process.
[0011] 2. In this utility model, through the coordinated operation of the sludge conveying component and the activated carbon water conveying component, combined with the precise control of the sludge pump, conveying pump and valve in each pipeline, a complete and continuous process is formed from the sewage entering the treatment tank D, through the filter press pretreatment, multi-stage treatment tank treatment, and heavy separation, to the final treated water entering the pre-storage tank and connecting to the MVR equipment. This greatly improves the efficiency of sewage treatment. At the same time, the stable process design also reduces water quality fluctuations caused by process interruption, ensuring the consistency and compliance rate of the treated water quality.
