Abstract
Activated carbon fiber Phenol-Containing Wastewater Treatment and renovation process thereof.The present invention relates to the treatment process of phenolic wastewater.Make the sorbent material of phenol with activated carbon fiber, phenolic wastewater is flowed through be equipped with the treatment unit of activated carbon fiber, the containing the phenol amount and can reach below the 0.5PPm of processed waste water.The present invention also proposes two kinds of later renovation process of activated carbon fiber absorption inefficacy: thermal regeneration and acetone extracting method of reproduction.
Description
The present invention relates to the treatment process of phenolic wastewater.
Phenolic wastewater is well-known to the harm of physical environment.Administering the method that phenolic wastewater adopted has steam to deviate from method, liquid-film method, solvent extration, active carbon adsorption and biochemical process etc.Contain the reduction of phenol amount in the waste water though these methods can make, its common shortcoming is the emission standard (0.5PPm) that does not still reach the Law on Environmental Protection regulation.In addition, steam is deviate from the method big energy-consuming, liquid-film method big energy-consuming and operational hazards, and the solvent extration energy consumption is big and have the solvent recuperation problem, and the biochemical process floor space is big, instability, it is poor that active carbon adsorption is removed efficient to lower concentration phenol.
Carbon fiber is the novel material that occurs nearly more than ten years, and the synthetic materials made from it has premium propertiess such as light weight, intensity height, high temperature resistant, corrosion-resistant, radiation hardness, is widely used in industrial circles such as aviation, machinery, electronics, chemical industry, building.Studies show that and select suitable organic fibre for use,, can obtain the different activated carbon fiber of structure with special method carbonization-activation treatment.Activated carbon fiber is a kind of sorbent material efficiently, it is compared with powdered activated carbon, it is (big as specific surface area not only to have a series of excellent comprehensive performances, pore size distribution is narrow and mainly be micropore, and adsorptive capacity is big, and rate of adsorption and desorption rate are all very fast, pollutent to lower concentration still has higher adsorption efficiency etc.), and on engineering is used, have greater flexibility, and can be made into forms such as yarn, cloth, felt, honeycomb structure, satisfy the requirement of various uses.Therefore, in the last few years the research of activated carbon fiber and Application and Development thereof to be operated in some countries (as the Soviet Union, Japan) very active.
The present invention utilizes activated carbon fiber to make the sorbent treatment phenolic wastewater, and content of phenol in waster is reduced to below the emission standard 0.5PPm of Law on Environmental Protection regulation, and the situ regeneration method of activated carbon fiber of adsorbing after saturated is provided, and makes it and can reuse.
Phenolic wastewater is flowed through and is filled with the treatment unit of activated carbon fiber, and contained free phenol is just adsorbed by activated carbon fiber in the waste water, and absorption must be carried out under neutrality or acidic conditions.In order to make the treating processes activated carbon fiber keep being evenly distributed, current are unimpeded, and treatment unit can be made segmented connection, separates with dividing plate with holes between every two segment.In the treating processes sometimes owing to the impulse action of current may make activated carbon fiber press together to influence current unimpeded, solution to this problem can be with the upright placement of device, water (flow) direction adopts counter-current, enter from the bottom, flow out on top, the downward gravity of impulse force on the current direction and activated carbon fiber is offseted, thereby prevent that activated carbon fiber is pressed together, the maintenance current are unimpeded and current are contacted with activated carbon fiber more fully, can improve treatment effect.
Adopt method Phenol-Containing Wastewater Treatment provided by the present invention, before the activated carbon fiber in treatment unit lost efficacy, the phenol amount that contains in the processed waste water was all below 0.5PPm.Whether activated carbon fiber lost efficacy or near losing efficacy, can determine by the phenol amount that contains that detects treatment unit water outlet water sample.When the water sample of water outlet contains the phenol amount near 0.5PPm, activated carbon fiber in the treatment unit is described near losing efficacy, at this moment should more renew or through the regenerated activated carbon fiber.To the judgement when used activated carbon fiber lost efficacy, general available activated carbon fiber treatable waste water total amount compare with actual treated wastewater flow rate and make.When the wastewater flow rate of actual treatment when reaching the treatable waste water total amount of activated carbon fiber institute, can judge that activated carbon fiber near losing efficacy, at this moment just should note detecting the phenol amount that contains of treatment unit water outlet water sample, to determine whether activated carbon fiber lost efficacy.Activated carbon fiber treatable waste water total amount and activated carbon fiber itself relevant to the factors such as the phenol amount that contains of the total amount of the activated carbon fiber that loads in the adsorptive capacity of phenol and the treatment unit and processed waste water, usually: the treatable waste water of activated carbon fiber
Total amount=(activated carbon fiber total amount * activated carbon fiber adsorptive capacity)/(content of phenol in waster before handling)
Be two examples below with the inventive method Phenol-Containing Wastewater Treatment:
1, treatment unit is the garden cylindricality, 10 centimetres of diameters, and long 2 meters, the activated carbon fiber total amount of filling is 1.7 kilograms, the adsorptive capacity of activated carbon fiber is 196 milligrams of phenol/grams.Content of phenol in waster is 50PPm before handling, the flow for the treatment of processes waste water by treatment unit be the 13-25 liter/hour, actual treatment waste water total amount is 6000 liters, waste water contains the phenol amount after treatment and reduces to below the 0.1PPm.
2, handling preceding content of phenol in waster is 200PPm, and treating processes waste water is 14 liters/hour by the flow of treatment unit, and actual treatment waste water total amount is 1600 liters, and treatment unit is identical with example 1 with other conditions, and waste water contains the phenol amount after treatment and drops to below the 0.1PPm.
The present invention also provides two kinds of activated carbon fiber absorption saturated (promptly losing efficacy) later renovation process, and a kind of is the thermal regeneration method, and another kind is an acetone extracting method of reproduction.
1, thermal regeneration method.The carbon fiber that lost efficacy is placed process furnace; under nitrogen protection, be warming up to 300-1000 ℃; when the adsorbed phenol of the reactive fibre that is reproduced is mainly phenol; Heating temperature is advisable with 300-800 ℃; when the adsorbed phenol of the activated carbon fiber that is reproduced also has some other condenses (as the P-F condenses) except that phenol, then should be heated to 1000 ℃ and be advisable.This is because the carbonization temperature of phenol is lower than other phenolic condensates, so heating should come the attemperation height according to the adsorbed material of the activated carbon fiber that is reproduced, to reach best regeneration effect.Adopt thermal regeneration method regenerated activated carbon fiber generally still can keep its original adsorptive capacity, the advantage of thermal regeneration method is a favorable regeneration effect, and the direct carbonization of aldehydes matter that the activated carbon fiber desorption comes out is fallen, and need not do other processing.
2, acetone extracting method of reproduction is treating that the regenerated activated carbon fiber puts in the extractor, and with acetone extracting 2-5 hour, washing again was then in 250-300 ℃ (preferably 270 ℃) oven dry down.Its adsorptive capacity of regenerated activated carbon fiber is regenerated for the first time and generally can be reached more than 70% of original adsorptive capacity in this way, and for the second time later its adsorptive capacity of regeneration then keeps the original adsorptive capacity of regenerated for the first time always, and decline is just arranged after using 40 times repeatedly slightly.The advantage of this method is simple to operate, and extraction solvent is reusable, and the material that extracts can concentrate recovery, and the activated carbon fiber loss is few in the regenerative process.
The method of Phenol-Containing Wastewater Treatment provided by the present invention, its equipment is simple, easy to operate, power consumption is few, floor space is few, the efficient height, waste water can reach the discharge standard of regulation through single treatment, and also can repeatedly regenerate after the used activated carbon fiber of method lost efficacy and reuse, and the inventive method is particularly useful for processing and contains the lower waste water of phenol amount.
