摘要
介绍了应用SBR法处理屠宰废水的试验研究，考察了COD、BOD5、SS、TN的去除效果和主要影响因素，确定了运行程序及工艺参数。在优化条件下稳定运行的处理效果为：运行周期12h；BOD5、COD与TN的去除率分别为90％、85％和80％以上，SVI始终低于1200mg／L，菌胶团密实，沉降性能好，为解决中小型屠宰厂废水处理提供了一条有效途径。
In this paper, the experiment on treatment of slanghter - house wastewater by sequencing batch reactor(SBR) was studied. Degradation behaviour of COD, BOD5, SS, TN and main effective factors were examined. operating precedure and technological parameters were determined in the experiment. Degradation behaviour of steady - state operation under optimun corditions was as follows: operation period was 12 hours,the removal rate of BOD5, COD and TN was respectively above ninty, eighty - five and eighty percent, SVIwas below 1200 milligram per liter all along, sediment function was well. It provides a new effective way to solve the envinonmental pollution problem of medimn or small slanghter - house wastewater.
