By applying of iron-carbon micro-electrolysis with Fenton reagent oxidation technical process to treat organic wastewater from a Vitamin C pharmaceutical plant by means of orthogonal experimental design to determine the optimal operating condition of iron-carbon micro electrolysis technique is:Volume ratio of ferrous versus carbon powder as 1:1, Volume ratio of ferrous and carbon powder versus water as 0.435, reaction duration as 3 hours and pH value as 2.2. CODCr removal rate and colourity rate after Iron-carbon micro electrolysis treatment is 56% and 25%. Optimal operating condition for Fenton reagent oxidation process is:quantity of H2O2 as 0.4ml/L, ferrous iron concentration as 10mg/L and reaction duration as 2 hours. CODCr removal rate and colourity rate after Fenton reagent oxidation process is 36% and 83%. The final effluent CODCr after overall treatment was from 245 mg/1 down to 50~70 mg/l. Colourity was from 200 times down to 25 times.According to the optimal operating condition from laboratory and the actual plant operation situation with client's expectation, perform basic engineering as well as detail engineering further to define wastewater treatment methodology. Deliver engineering deliverables including technical specification, drawings and lists as well as project execution cost estimation and operation cost forecast. During project construction management phase, keep on tracking the construction quality, progress and cost in the same time by ensuring Health, Safety and Environment rules. Handover the waste water extension plant to client with in-spec effluent as technical requirement.
