Activated carbon treatment system for acetone wastewater

Abstract

The invention discloses an activated carbon treatment system for acetone wastewater. The system comprises a plurality of activated carbon adsorption tanks arranged in parallel, and the activated carbon adsorption tanks arranged in parallel are connected through common water inlet pipelines, condensation pipelines, steam pipelines and water outlet pipelines; Each activated carbon adsorption tank is provided with an activated carbon layer in the middle and upper part of the interior, and a steam plate is arranged in the internal middle. The activated carbon layer and the steam plate are spaced at a certain distance, generally 3-5 cm; the acetone wastewater activated carbon treatment system of the present invention solves the problem of activated carbon regeneration. , can have a great use value, and the steam used is a cheap product or a surplus product in this type of factory, so the economy is better.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an activated carbon treatment system for acetone wastewater. Background technique [0002] Due to technical limitations in the treatment of acetone wastewater in the prior art, most of them use distillation towers to distill acetone out. The limitation of this equipment is that the cost is high, and the economical efficiency of acetone wastewater with lower concentrations is unreasonable; further, large Some adsorption tanks do not have the function of in-situ regeneration. Generally, the regeneration of activated carbon needs to be dried and then returned to the processing plant for high-temperature regeneration. [0003] Activated carbon has a highly developed pore structure and a large specific surface area. It is non-toxic, odorless, and has a strong adsorption capacity for molecules. It is an excellent adsorbent and is widely used in the fields o...

Problems solved by technology

[0002] Due to technical limitations in the treatment of acetone wastewater in the prior art, most of them use distillation towers to distill acetone out. The limitation of this equipment is that the cost is high, and the economical efficiency of acetone wastewater with lower concentrations is unreasonable; further, large Some adsorption tanks do not have in-situ regeneration function. Generally, the regeneration of activated carbon needs to be dried and returned to the processing plant for high-temperature regeneration.

[0003] Activated carbon has a highly developed pore structure and a large specific surface area. It is non-toxic, odorless, and has a strong adsorption capacity for molecules. It is an excellent adsorbent and is widely used in the fields of water purification and wastewater treatment. After the cycle, the adsorption capacity will be saturated, that is, it will no longer have the adsorption function. If it is replaced and discarded directly, it will undoubtedly be a waste of resources and will also pollute the environment.

[0004] The wastewater treatment process of activated carbon production in the prior art is too simple and extensive, the wastewater has not been recycled, and the water consumption is relatively large, resulting in increased production costs; the neutralized wastewater still contains a large amount of calcium phosphate and other sediments after running for a period of time Finally, the accumulation of sediment in the sedimentation tank not only affects the sedimentation effect, but also causes problems such as difficult to clean the sediment
