Description
Technical field
The utility model belongs to technical field of waste resourceful treatment, specifically just relate to materialized mud washing recycling treatment process and specific equipment thereof, materialized mud is carried out the treating processess such as dissolving washing, dehydration, mud dissolved salt content is reduced, can be used as cement kiln batching to use, removal of impurities purification and evaporative crystallization are carried out to filtrate simultaneously, obtain product salt, achieve minimizing and the resource utilization of mud.
Background technology
In water treatment field field, especially in modern industry wastewater treatment, because waste component is complicated, be difficult to biological degradation, therefore, physico-chemical processes is the conventional means of wastewater treatment.But, produce along with a large amount of materialized mud in the process of materializing strategy, namely materialized mud is add soda acid and PAC in flocculation sediment and Chemical deep treating processes in wastewater treatment process, the residual body of the impurity formed after PAM, this mud is generally containing a large amount of Calucium Silicate powder, calcium carbonate, calcium sulfate, magnesium hydroxide etc., in addition, also containing dissolved salt < 8%, containing potassium < 0.5%, sodium < 3.0%, chlorine < 4.5%, if by process such as its direct landfills, salinity will be wasted in a large number and be added sludge treatment cost, and cause secondary pollution.
At present, the method extracting salinity from mud mainly contains acidization, ion exchange method and embrane method etc.
Acidization is (as pH<3.75) namely at the low ph, adopts that strong acid can dissolved be out from flocs unit by aluminium salt.Acidization comprises three steps: sludge dewatering, acidification, isolation of purified.The weak point of the method is poor selectivity, and the metal of reuse in addition to aluminum, also has some other solubility or colloidality material; The organic substance in water outlet can be made to produce accumulation; If acidification sludge is without decolorization filtering and crystallization, the effluent quality of impact process water.
Liquid-phase ion exchange is a kind of liquid-liquid extraction, can from the mud through acidifying isolation and identification salt, make it obtain reuse, its working process has been come primarily of a kind of carrier mixed solution.This method operation is comparatively complicated, and needs sensitiveer Controlling System.
The composite membrane adopted in embrane method is made up of the voided polytetrafluoroethylene film of thick about 0.5mm and the thin spherolite of embedding diameter about 100 μm wherein, and thin spherolite plays the effect of exchanger, and it has very strong avidity to selected ion.Its step is divided into the regeneration of selective adsorption, desorb and film.The absorption of composite membrane has selectivity and exclusiveness, has good persistence simultaneously, can be recycled more than 30 times, but cost is higher, and running and comparing is complicated, and the part salt be adsorbed on film likely can come back in mud.
Meanwhile, the mode process such as burning, landfill, compost be agricultural are mainly contained to the final process disposal technology of mud.Burning method lignin-sludge is current most effective means, but the calorific value of mud is depended in sludge incineration, the size of calorific value determines the production cost of sludge treatment, and materialized mud mainly refractory organic with the interactional product of PAC, PAM, its calorific value is very low, so the residue that sludge incineration produces is considerable problem with or without recycling value later.The operation of landfill disposal mud is relatively simple, investment cost is less, processing costs is lower, strong adaptability, but the meeting severe contamination soil such as the poisonous and harmful heavy metallic in landfill process in mud, dissolved salt and pathogenic micro-organism and water resources, must consider the geology of landfill yard, the hydrology and edaphic condition, use need be subject to a definite limitation, and the useful matter existed in mud (as dissolved salts material) is wasted in a large number, resource utilization degree is low.The agricultural method of compost is applicable to the process of the municipal sludge that organic content is high, inorganics is low, for the materialized mud containing inorganic componentss such as a large amount of Calucium Silicate powder, calcium carbonate, calcium sulfate, magnesium hydroxides, be unfavorable for the degraded and absorbed of plant to organic composition, and take a large amount of soil.
