Embodiment approach
[0035] In the following, according to an embodiment of the present invention, a device for treating wastewater containing sulfur compound DMSO will be described with reference to the accompanying drawings.
[0036] refer to figure 1 , The wastewater treatment device includes a device main body 1, and the device main body sequentially includes a fixed bed 2 and a fluidized bed 3 arranged on the fixed bed 2.
[0037] Near the fluidized bed 3, a pH meter 12 and a pH adjustment pump 13 are provided. A backwash tank or a backwash water collection channel 6 is also provided near the fluidized bed 3, so that backwash waste water flows into it. To this end, the waste water is forced up to the upper region 4 of the device.
[0038] The tanks 6 are respectively equipped with effluent blocking walls 5, which are used as devices for preventing the flow carrier in the backwash wastewater from flowing out. Each effluent blocking wall 5 is a mesh structure made of wire fabric, porous meta...
Embodiment 1
[0070] In this example, 7.1 L of fluid carrier and 142.9 L of fixed carrier were loaded in the treatment device used (that is to say, the ratio of fluidized bed to fixed bed was 1:20). Wastewater containing DMSO was treated by using the treatment device of this embodiment, and the result was that the content of DMSO in the treated water was 25 mg / L. The concentration of S-TOC is 15mg / L. Therefore, the TOC removal rate was 92.4%. The pH in the area of the plant corresponding to the fluidized bed was 7.2, while the pH of the treated water was 6.5.
Embodiment 2
[0072] In this embodiment, 15 L of fluid carrier and 135 L of fixed carrier are loaded in the treatment device used (that is to say, the ratio of fluidized bed to fixed bed is 1:9). Wastewater containing DMSO was treated with the treatment device of this embodiment, and the result was that the DMSO content in the treated water was 6 mg / L. The concentration of S-TOC is 8mg / L. Therefore, the TOC removal rate was 95.9%. The pH in the area of the plant corresponding to the fluidized bed was 7.2, while the pH of the treated water was 6.9.
