摘要：Release of AOX (Adsorbable Organic Halide) from pulp and paper industry is now the main environmental concern after statutory authorities notified and set the standard norms for AOX. To meet the norms, the source of release of AOX compounds and its concentration must be known for the treatment of effluent in a better way. This paper deals with the source of release of AOX compounds and its concentration in the particular effluent. The main source of release of AOX compounds are bleach plant effluent. Characterization of bleach plant effluents (Chlorination-stage, Extraction-stage, Hypo-Stage and Combined Stage) collected from agro based small pulp & paper mills and wood based large pulp & paper mills are done to know the AOX value in both type of industries. Characterization of bleach plant effluent shows that the E-stage effluent of bleach plant have high AOX value (88-109 mg/L) as compared to the other stage of agro and wood based mill. On other hand in agro based mills, AOX value is in higher range (95-109 mg/L) as compared to wood based mills (88 -98 mg/L) in E-stage effluent.
