Study on Aspen P-RC APMP Wastewater Characteristics and Its Anaerobic Treatment

Aspen P-RC APMP wastewater characteristic was studied in this paper,and its anaerobic biotreatability and methanogenic toxicity were evaluated by the means of biological methane potential (BMP) test and anaerobic toxicity assay (ATA) test. Continuous anaerobic treatment of the wastewater was carried out in a UASB reactor. The results showed that aspen P-RC APMP wastewater contains substances which inhibit methanogenic microorganism,but this harmful effect can be released after a period time of cultivation. Aspen P-RC APMP wastewater is fairly anaerobic biotreatable,and the CODCr and BOD5 removal reaches 64.2% and 93.0% respectively.
