摘要：
Intensive amount of manure produced in pig breeding sectors represents negative impact on the environment and requires optimal management. Anaerobic digestion as a well-known manure management process was optimized in this experimental study by pulsed electric field (PEF) pretreatment. The effect of PEF on methane production was investigated at three different intensities (15, 30 and 50 kWh/m(3)). The results indicate that the methane production and chemical oxygen demand (COD) removal was improved by continuous escalation of applied intensity, up to 50 kWh/m(3). In comparison with untreated slurry, methane production and COD removal were increased up to 58% and 44%, respectively.
