The new treatment system was designed to reduce overall liquid waste from 300 to 130 tons per day, a 56% reduction. To achieve a reduction in wastewater discharge, the following changes/addi- tions were made to the system design: 1. Sludge collection systems were added to increase water recovery; 2.

In a biological denitrification system involving large volumes of waste- water, it is obviously necessary to ensure that the methanol added is just sufficient to remove the nitrate present; addition of too little will leave residual nitrate and too much will cause an unnecessary in- crease in cost of treatment as well as an undesirable increase in the oxygen demand of the effluent.

Treatment of methanolic wastewater was studied in an anaerobic sequencing batch reactor (ASBR) for a period of 193 days. The results showed that the system worked efficiently when the system volume loading was of 4–8g COD/l. d. Both Methanol concentration and bicarbonate play an important role in the anaerobic conversion of methanol.

In our study, two-stage anaerobic system was employed to treat high concentration ,methanol wastewater,. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion ,of methanol wastewater, was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable …
