Abstract
The invention provides a method for recovering residual gum from natural rubber processing wastewater. The method comprises two processes of utilizing coagulation technology to separate the residual gum of wastewater and utilizing diluted hydrochloric acid to recover the residual gum. Polyaluminium chloride (PAC) is screened out as coagulant, and polyacrylamide (PAM) is used as coagulant aid. The PAC and the PAM are added to wastewater, and then the diluted hydrochloric acid is added to an obtained flocculating constituent, and after the reaction of the flocculating constituent and hydrochloric acid is over, the products of the reaction are filtered and then are rinsed once or twice, so as to obtain a milk white rubber body.
Description
1, technical field
The present invention includes and utilize coagulation technology to separate, utilize dilute hydrochloric acid to reclaim two processes of cull the cull of natural rubber processing waste water, be the water pollution application technology as the second resource in Environmental Science and Engineering field.
2, background technology
Up to now, in natural rubber processing waste water (being called for short Rubber Industrial Wastewater down) processing, there is not the report that reclaims at the efficient cull that its pretreatment stage utilizes flocculation agent to carry out.
3, summary of the invention
In order to prevent that Rubber Industrial Wastewater is unfavorable for what cull reclaimed behind long the going bad storage period, avoid the waste water resource waste simultaneously, for alleviating its follow-up processing pressure, the present invention with coagulation, add in the hydrochloric acid and be applied to successively in the Rubber Industrial Wastewater to separate the remaining rubber of purification with substep.
The technical solution adopted for the present invention to solve the technical problems:
Filter out polymerize aluminum chloride (PAC) as coagulating agent from six kinds of coagulating agent, polyacrylamide (PAM) is done coagulant aids.PAC is joined in the waste water, stir, add PAM again, leave standstill after the stirring, filter when treating that coagulation is finished substantially,, treat that flocs unit and hydrochloric acid reaction finish toward obtaining adding dilute hydrochloric acid in the flocs unit, be its when all becoming the oyster white flco, filter, wash and obtain oyster white rubber one to twice.
4, embodiment
Get waste water sample 500ml, low-grade fever adds polymerization AlCl to 35-45 ℃
3(add-on 100mg/L) is with 120r.min
-1Add polyacrylamide (add-on 0.8mg/L) after stirring 10s.Thereafter reacting dynamics condition: mix stages stirs 30s, 120r.min
-1Step of reaction stirs 20min, 30r.min
-1Sedimentation 30min filters, and adds the dilute hydrochloric acid of 10g/L in the flocs unit that obtains, and all becoming the oyster white flco with flocs unit serves as to react to finish indication, refilters the oyster white flco, washes and obtains oyster white rubber one to twice.
Claims (3)
1, a kind of method that reclaims cull from the natural rubber processing waste water is characterized in that comprising and utilizes coagulation technology to separate, utilize dilute hydrochloric acid to reclaim two processes of cull the cull of waste water.
2, the described coagulation technology that utilizes of claim 1 separates the cull of waste water, it is characterized in that utilizing polymerize aluminum chloride (PAC) as coagulating agent, and polyacrylamide (PAM) is done coagulant aids.PAC is joined in the waste water, add PAM after the stirring again, leave standstill behind the restir, be settled down to coagulation and finish substantially, filter.
3, utilize dilute hydrochloric acid to reclaim cull to it is characterized in that in claim 2, filtering the dilute hydrochloric acid that adds 10g/L in the flocs unit that obtains described in the claim 1, treat that flocs unit all becomes the oyster white flco after, filter, wash and obtain oyster white rubber one to twice.
