Experimental Study on the Treatment of Tofu Wastewater by Improved CSTR
An improved continuous stirred tank reactor(CSTR)was used for anaerobic digestion of tofu wastewater at 35 ℃,and the HRT was set to 26,17,13 and 8 days,respectively,to explore the effects of different organic loads on the anaerobic digestion.The results showed that the daily gas production increased with the shortening of HRT,and the average methane content increased from 51.06%to 56.00%.
