PROCESS FOR A UNITARY PURIFICATION OF EFFLUENTS RESULTING UPON 1-NAPHTHOL AND 1-NAPHTHALENOL METHYLCARBAMATE AND 1-NAPHTHALENOL METHYLCARBAMATE SYNTHESIS

摘要

the invention refers to a process of treatment of residual efluentilor uniform, evacuated from the fabricatiile 1-naphthol and methylcarbamate 1 - naftalinol.the process proposes different sources and directing their separation, depending on composition, directly to the sewage treatment by biological and local station.pooled from the two sources fabricatii and to be subjected to a local sewage process are separately treated, in order to u00eendepartarii solventilor or rasinilor organic fluidsthen through the correction necessary ph (up to 3 4) precipitation and separation by filtration takes place 1 - naftolului gross, the purity obtained in similar technology of synthesis.eluentii filtrati are reunited and subjected to surgery suction on fine-grained coal actively, in order to epurarii advanced organic compusilor.get a anorganica effluent with loading, whose content of na2so3 is necessary neutralizarii sources with active chlorine in the context of the location.the surface adsorbing regeneration is done by washing at low tide with organic solvent (methanol).
