摘　　要：相比其它类型白酒酒糟,米酒酒糟具有含水量高的特点,其所含的大量高浓度COD、BOD、氨氮、TP等污染物,不经有效处理直排进附近水体,极易污染周边环境,影响当地生态环境安全,其衍生的环境风险已成为制约产业发展的重要阻力。本文研究了采用USR厌氧工艺处理高浓度酒糟废液有机污染物的工艺性能,验证其技术可行性。试验结果表明:在反应器容积负荷达到13.1 kgCOD_(Cr)/(m^(3)·d)、污泥负荷达到1.6 kgCOD_(Cr)/(kgVSS·d)、HRT为8 d下,其COD去除率大于80%,且运行稳定,大大减轻了后续环保治理有机物负荷的压力。该反应器运行成本远低于其它酒糟废液治理路径,为解决客家米酒产业发展造成的环境问题,提供了合理的治理思路。Compared with other types of wine lees,rice wine lees have the characteristics of high moisture content.It contains a large number of high concentration of COD,BOD,ammonia nitrogen,TP pollutants such as extremely easily without effective treatment straight into nearby water bodies that affects the local ecological environment security.Derivative of environmental risk has become an important resistance which restrict the development of the industry.In this paper,the process performance of using USR anaerobic process to treat organic pollutants from high concentration distiller's lees waste liquor was studied and its technical feasibility was verified.The experimental results show that when the reactor OLR reaches 13.1 kgCOD_(Cr)/(m^(3)·d),SLR reaches 1.6 kgCOD_(Cr)/(kgVSS·d)and HRT is 8d,the COD removal rate can be more than 80%,and the operation can be stable which greatly reduces the load pressure of organic matter in the follow-up environmental protection treatment.The operation cost of the reactor is much lower than other treatment routes of distiller's grains waste liquid which provides a reasonable treatment idea for the environmental problems of hakka rice wine industry development.
