Exp eriment s were carried out u sing a laboratoryscale anaerobic fixed bed reactor op erat ed at different hydraulic ret ention times ( H R Ts) . The p rocess efficiently removed four types of chlorinated guaiacols when the HR T was 24 h . In this condition , all chlorinated guaiacol s were almo st completely removed. The microbial community structure in the reactor was not changed significantly during operating period. Key words : anaerobic t reat ment ; chloroguaiacol s ; fixed bed reactor CLC number : X703 . 1 　　　Document code : A 1 　Introduction Traditionally , t he concer n over di schar ge s f ro m t he p ulp and p ap er in du st ry ha s been focu sed on t he ri sk of fiber depo sition s and
