Treating Starch Wastewater Reclaim Bioenergy by EGSB Process and High Value Use of Biogas

摘要：

the expanded granular sludge bed (EGSB) reactor anoxic/aerobic (A/O) process has been used for treating highly concentrated starch wastewater, and the biogas produced in EGSB was purified. Under the condition of 35 ℃, the COD volume load of EGSB reaches up to 20kg/(m3·d), and the combined process removal rates of COD,BOD5 and SS were 98.5％,99.5％and 95％,respectively. After being treated by the combined process, the effluent quality is able to satisfy the demands of discharge. After purification treatment, the methane content of biogas was high than 98％, and the hydrogen sulfide content was below 30 mg/Nm3. The natural gas production was 6000m3/d, the high value use of biogas was achieved.
