云南保山某奶制厂污水处理，废水排放处理成功案例

进出水水质情况

处理工艺

本工程废水中属高浓度有机废水，可生化性好，适合采用生化处理。通过工艺的选择比较设计中采用了厌氧UASB和好氧SBR的组合工艺。

针对废水悬浮物较多的特点，采用格栅和固液分离机两级预处理进行去除，避免对后续UASB的影响。

废水进入氧化沟后，在曝气设备作用下快速、均匀地与沟中混合液混合。混合后水在封闭的沟渠中循环流动。采用阶段曝气方式，在氧化沟内造成缺氧和好氧交替的生化环境，使该系统在去除含碳有机物的同时，具有一定的脱氮效果。在菌种投放和培养驯化并正常运行之后，经平流沉淀池沉淀，COD去除率达到90%以上，氧化沟出水COD降至150mg/L以下。

主要设计参数

（1）为进气格栅和固液分离器设置一个细格栅，栅条之间的间隙为5mm。固液分离器采用带自动冲洗装置的旋转圆筒。固体废物的分离可以用生活垃圾处理。

（2）水井和调节池配备2个潜水泵，将废水排入调节池。在调节池中设置提升泵单元，将废水提升到UASB反应器中。调节池水力停留时间为8h，1170m量发现，结构的22.0m * 12.0m * 5.0m大小。

技术经济指标

这个项目的总投资是600万元。耗电量0.33（kW·h）/ m和废水，直接运行成本为0.35元/平方米和废水。
