The main chemical characteristics of the waste—water collected from
Nanyang Pukang Group Chemical& Pharmaceutical Factory were：BOD =60
mg／L．COD=992 mg／L；pH=7．64；and color levels=700 units．The BOD／C0D ratio of 0．O6 indicates that the wastewater was not amenable to a further biological treatment (easily biodegradable organics were eliminated by pre—treatment in UASB and SB Rreactors)． The composition of organics in the wastewater measured bv GC—MS is shown in Fig．1 and Table 1．It can be seen from Table l that the residual recalcitrant organics consisted of alcohols (36．68％ ),phenols (6．88％ ),ketonnes,quinines,parafi ns,nitrogenous and sulfur compounds．Of the total recalcitrant organics．which consisted of l9．65％ Of 2一methyl—l—pentano1．1 7．03％ of 2 3一dimethyl—l—butano1．and 8 14％ of 2一(methyl—mercapto1 benzo—thiazole,the percentage of other organics varied between 0．93％ and 3．1％ (Table l1．
1．2 Fenton’s reaction
0ne hundred milliliter of sample was introduced into a 25O—ml beaker at room temperature(25％1)．The pH of the sample was adiusted by adding sulfuric acid．20 g／t of FeSO4·7H2O and 3％ H2O2 were then added to the sample and the mixture was stirred and left at a standstill for l h．After sedimentation．the supematant was withdrawn for COD and color analysis．
