Embodiment 1-13
[0035] Add a certain amount of activated carbon to the activated carbon adsorption tank, pass waste water, and control a certain flow rate so that the waste water flows through the activated carbon layer from bottom to top, and the effluent is discharged into the storage tank. The experimental results are shown in Table 1.
[0036] Table 1.
[0037]
[0038] It can be seen from Table 1 that when using the technical scheme of the present invention to treat the phenol-containing wastewater of the examples, the optimal treatment parameters are: the pH of the wastewater during adsorption is controlled at 2-7, the water flow rate is 10m / h, and the amount of activated carbon used is 1.5 -2.0g / L, the adsorption temperature is room temperature. Too low or too high temperature will reduce the removal rate, but this method is still applicable in cold winter.

Abstract
The invention discloses a phenol-containing wastewater removal device and process. The phenol-containing wastewater removal device comprises an activated carbon adsorption tank, a water storage pond, an alkaline liquid tank, a sodium phenolate solution tank, an acid liquid tank, an extraction tower, a solvent tank and a water pump, wherein the activated carbon adsorption tank comprises a first adsorption tank and a second adsorption tank which are connected in series. The removal process comprises the steps of flowing the phenol-containing wastewater through an activated carbon layer in the adsorption tank to regenerate adsorption-saturated activated carbon; then, continuing to adsorb wastewater after washing the saturated activated carbon to be neutral; reducing sodium phenolate into phenol in the sodium phenolate solution tank; and removing an oil layer in the extraction tower so as to recover phenols. According to the technical scheme of the invention, the process is simple in operation, good in water treatment effect, high in regeneration efficiency and capable of recycling activated carbon; in addition, phenol substances can be recovered after regenerated so that the wastewater treatment cost is greatly reduced.
Description
Technical field [0001] The invention relates to a wastewater treatment device and a treatment method in the chemical industry, in particular to a device and a process for removing phenol-containing wastewater. Background technique [0002] The rapid development of industrialization has produced more and more waste water. If the waste water is not treated in time, it will inevitably pose a major threat to the global environment and human health. Phenolic substances are an important chemical raw material and intermediates, which are widely used in the paper industry, petroleum industry, printing and dyeing industry and the preparation of various pesticides. Because they are difficult to degrade, they bring great changes to wastewater treatment. . Phenolic organics are highly toxic, low concentration can denature protein, high concentration can precipitate protein, directly damage various cells, and have a strong corrosive effect on skin and mucous membranes. Long-term drinking of...
