摘　　要：针对来水复杂、水量小的混合型重工业污水,污水厂的设计采用了水解酸化与A2/O相串联的污水处理工艺。运行结果表明:COD、BOD5、氨氮和SS去除效率分别为90%、92.9%、72.3%和95%,出水各项指标均达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)中的一级B标准.。且该工艺具有运行费用低、处理效果好、操作管理方便等一系列优点。According to characteristics of mixed heavy industrial sewage including complex components and small amount, wastewater treatment plant used hydrolysis acidification and A2/O process. The running results show that the removal rates of COD, BOD5 , NH3-Nand SS are 90%,92.9%,72.3% and 95%,respectively. Indexes of the effluent can approach the first class criteria specified in B standard of ＂Urban Sewage Treatment Plant Emission Standard＂（GB 18918-2002）.The process has many advantages of low running cost, good treatment effect, easy operation and management.
