Results and discussion
Any other information on results incl. tables
Complete-mix, bench-scale, continuous-flow activated-sludge reactors were used to treata synthetic wastewater containing a "base mix" plus the priority pollutant(s) under study. The "base mix" included:ethylene glycol, ethyl alcohol, glucose, glutamic acid,acetic acid,phenol, ammonium sulfate, phosphoric acid, and salts.The "base-mix" and priority pollutants were added so that the BOD5of the wastewaterwould be approximately 250 mg/L. The priority pollutants were studied as single-pollutantsystems and in combinations of three to a system.
Operation of the reactors with synthetic wastewater amended with 1,2 -dichloropropane showed that influent concentrations of 182 mg/L were reduced to 1.8 mg/L in the effluent, corresponding to 99% removal efficiency. The mechanism responsible for the loss of 1,2 -dichloropropane from the systems was volatilization.
Applicant's summary and conclusion
- Conclusions:
- This study examined the feasibility of predicting biological treatment of combinations of priority pollutants by using information obtained for the treatabilty studies for single component systems. Continuous flow activated sludge reactors were operated on a synthetic wastewater supplemented with various test materials. Concentrations of the test materials was monitored in the influent and effluent from the reactors. Stripping was determined by measuring the concentration of test materials in the offgases of the reactors.
