摘要
运用属性综合评价法,评估了5项黄姜皂素废水处理工艺。通过确定评价指标的属性级别,建立分级标准矩阵,计算得到评价技术属性测度和各项工艺的分数。中和/沉淀-兼有脱硫功能的两相厌氧-固定化微生物-曝气生物滤池(GBAF)工艺得分最高;石灰中和-二级UASB-二级接触氧化工艺次之;内电解-三段式两相厌氧-生物接触氧化-催化氧化脱色处理工艺排第三;电化学-UASB-接触氧化-生物过滤工艺与EGSB-A/O-生物接触氧化工艺得分较低,但这2种工艺基本能满足达标排放要求。评价结果为环保行政管理部门进行环境管理、相关企业选择适用工艺提供科学依据。
Five treatment processes of wastewater from production of Dioscorea zingiberensis C.H. Wright were assessed using comprehensive attribute evaluation. By determining the attribute level of evaluation index, grading criteria matrix was established, and scores of the process and measures of the technical attributes were calculated. Neutralization/precipitation- two phase anaerobic-immobilized microorganisms-biological aerated filter with desulfufization function （GBAF） process got the highest score, followed by lime neutralization-two UASB-two contact oxidation process. Internal electrolysis-three section two phase anaerobic-biological contact oxidation-catalytic oxidative decolorization process ranked the third, and electrochemical-UASB--contact oxidation-biological filtration process and EGSB-A/O-biological contact oxidation process got lower scores. However, both the processes could basically meet the discharge standards. The evaluation results would provide a scientific basis for environmental management of environmental administrative departments and choice of applicable process for related companies.
