摘要
采用常温UASB反应器为主要单元,微动力好氧的滴滤床为辅的工艺处理食品废水。工程运行表明当进水COD_(Cr)浓度为1000～3000mg/L时,出水COD_(Cr)浓度可降至50～90mg/L。此工艺投资省、运行费用低、操作简单,可获得较好的经济效益和环境效益,能广泛应用于淀粉废水处理的实际工作中。
The waste water from food-making starch production is a highly-concentrated organic waste water.It is treated by a biochemical treatment technology using UASB reactor under normal temperature as the main treatment unit,and trickle bed as the secondary unit.These technics show that the use of the said technology not only saves investment,lowers operational cost and simplifies operation but also produces usable methane while the waste water after treatment can meet the standard before discharged so that good economic and environmental results can be obtained.
