Treatment of high density poultry manure by anaerobic pecked bed reactor
固定床厌氧反应器处理高浓度禽畜粪尿

In order to research on a highly-effective disposal of poultry manure through anaerobic biotechnology,an efficient anaerobic reactor with an effective volume of 20 L was designed according to the characteristics of anaerobic pecked bed reactor.Pen manure as raw material for fermentation,the raw water COD was adjusted between 4 820 and 54 000 mg/L.The whole process was 55 days,which was divided into two stages according to the raw of hydraulic retention time: the prophase(44 d) and the anaphase(11 d),in the ...
