摘  要:
用EGSB厌氧反应器处理了食品工业中用量最大的添加剂之一——瓜尔豆胶的生产废水。结果显示:本研究所用的EGSB厌氧系统处理瓜尔豆胶生产废水,在容积COD负荷达18kgCOD.m-3d-1(进水COD浓度为30000mg.L-1)时,去除率可稳定在80%以上;出水的pH稳定在7.5左右;容积产气率随容积负荷的提高而逐渐升高,COD负荷达到18kg.m-3d-1时,平均沼气产量为22L.0.5d-1,每公斤COD平均可产生0.54m3沼气;沼气中的甲烷含量最高可达到82%。

摘  要:
An EGSB anaerobic system was used to treat guar-gum wastewater.Results showed that COD removal efficiency could reach 80% with COD loading rate 18 kg·m-3d-1(influent COD was 30000 mg·L-1)and effluent pH 7.5.The biogas production was increased with the increase of organic loading,and the system obtained a gas yield of 22 L·0.5 d-1 when COD loading reached 18 kg·m-3d-1,and so about 0.62 m3 biogas was produced when 1 kg COD was removed.The methane content of the biogas could reach 82%.
