Description

The method of one Yeasts amalgamation method regenerated carbon
Affiliated technical field
The present invention relates to the method for a Yeasts amalgamation method regenerated carbon, belong to field of environment engineering.
Background technology
Active carbon is a kind of Powdered or granular black solid, has very flourishing pore structure and high specific area, and acid and alkali-resistance corrodes, and to biologically inert, is a kind of good sorbing material.Be widely used in the fields such as chemical industry, environmental protection, food and pharmacy, hydrometallurgy, catalyst carrier, electrode material and military chemistry protection.Himself is contaminated after having adsorbed organic matter for active carbon, need to regenerate to process or discarded.China reaches 10000 ton/years because of the waste active carbon that sugar industry produces, and owing to containing a large amount of nutrients in waste active carbon, bacterial reproduction is serious, and smell makes us suffocating.It is carried out recycling have important environmental protection meaning and the meaning that economizes on resources.
With organic matter leaching, decomposition or in-situ carburization with the way of having adsorbed organic Regenevating Waste Activated Carbon.At present, regeneration method of active carbon mainly contains hot method of reproduction, bio-regeneration method, wet air regeneration method, solvent regeneration process, chemical regeneration method, ultrasonic regeneration method and Photocatalytic Regeneration method etc.In numerous regeneration method of active carbon, hot regeneration technology is the most ripe, but its regenerative process duration, energy consumption is high, unstable product quality.Use the method regenerated carbon of microbial degradation, pore structure and pore-size distribution capable of reducing energy consumption, as to guarantee active carbon.Microbial method has been widely used in the fields such as sewage disposal, fabrication of new materials.Along with the development of modern science and technology, microbial method is applied in various fields such as food, space flight, heavy metal-polluted soil processing.The present invention uses saccharomycete to be the method for advanced treating active carbon hole internal sugar part, method in conjunction with the sugar part in Chemical Leaching activated carbon surface and macropore is regenerated to the useless activated carbon that sugar industry produces, microbial degradation and solvent reclamation are organically combined, their performances usefulness separately, and complement each other, improve the percent reduction of waste active carbon, guaranteed the original pore structure of active carbon and pore-size distribution.
Summary of the invention
The method that the purpose of this invention is to provide a Yeasts amalgamation method regenerated carbon.It is that the waste active carbon that produces take sugar industry is as raw material.In sugared production process, need to decolour with active carbon, the filter aids such as diatomite filter, and therefore, contain a small amount of sand in waste active carbon.After first dividing through 150 mesh sieves, the present invention removes the inorganic particles such as the sand that adulterates in active carbon, clay, then utilize the sodium tartrate aqueous solution or sodium citrate aqueous solution that the organic components such as caramel in activated carbon granule surface and macropore are leached, leachate contains a large amount of sugar parts, leaching agent also can be used as the animal foodstuff raw material, so leachate can be used as animal feed or feed-mixing water uses; In active carbon after leaching is processed, most of impurity is removed, then adding water mixes and adds saccharomycete solution, be equipped with the necessary nitrogen P elements of saccharomycete existence, control to control slurry temperature between 25 ℃~33 ℃, the pH value of system between 5.5~7.0, make saccharomycete degrade residual sugar part in the duct; With diluted sodium hydroxide solution, saccharomycete, small organic molecule being cleaned out rear filtration, drying after degraded is completed can make active carbon realize regeneration.
The present invention has made regenerated carbon by following measures:
(1) waste active carbon that produces take the caramel production process is got sieve and is gone up part as raw material after sieving with 150 order square hole screens;
(2) active carbon, water, leaching agent are mixed according to certain mass ratio, then leaching 2~5h filters, and gets filter cake standby;
(3) filter cake that step 2 is made mixes with water, controlling active carbon/water (mass ratio) is 3.0~10.0, and add saccharomycete solution, sodium nitrate and sodium phosphate and stir, control slurry temperature between 25 ℃~33 ℃, the pH value of system between 5.5~7.0, react afterwards 3~12h;
(4) the active carbon mixed liquor that step 3 is made filters, and gets filter cake, is 5%~15% sodium hydroxide solution cleaning active charcoal with mass concentration;
(5) can obtain regenerated carbon after the dehydration of the process of the active carbon after the cleaning, drying.
The saccharomycete associating chemical method regenerated carbon of the present invention's preparation has carried out good protection due to the method for using saccharomycete degraded and medicament stripping to combine to the original pore structure of active carbon and pore-size distribution.Contain a large amount of sugar parts and a small amount of sodium tartrate, natrium citricum in process in leachate, the mixing water that can be used as animal feed uses, and is favourable to the growth of animal.Without poisonous and harmful substance discharging, be a resource-conserving, environmentally friendly complete set technology in production process.
