为研究泰安市某污水处理厂采用改良Carrousel氧化沟工艺处理矿区污水的效果，本文比较分析了该污水处理厂改造前后进出水中COD、BOD、氨氮和SS的浓度大小，并得出如下结论：改造后污水处理厂对COD、BOD、氨氮和SS的去除率分别在72.5%、65.9%、55.8%和84.6%左右，与改造前的49.1%、56.0%、6.4%和86.8%相比，除SS的去除率基本不变外，COD、BOD、氨氮的去除率均有所提高，出水整体能够达到《城镇污水处理厂污染物排放标准》（GB18918-2002）一级B标准，即COD≤60 mg/L，BOD≤20 mg/L，SS≤20 mg/L，氨氮≤15 mg/L；氨氮去除效果与改造前相比得到明显改善，去除率提高了49.4%。

In order to study the wastewater treatment in mining area in Tai'an which used the improved Carrousel oxidation ditch process in a wastewater treatment plant, this paper compared and analyzed the concentration size of COD, BOD, NH3-N and SS before and after the sewage treatment plant improvement. And the paper drawn the following conclusions:after the sewage treatment plant using the improved sewage treatment process, the removal rate of COD、BOD、NH3-N and SS changed from 49.1%,56.0%,6.4%, 86.8% to 72.5%,65.9%,55.8% , 84.6%.The removal rate of SS remained unchanged basically. The removal efficiency of COD, BOD and NH3-N were improved. The effluent can reach the level of B standard of"town sewage treatment plant pollutant discharge standard" ( GB18918-2002 ) on the whole, which is COD ≤ 60 mg / L, BOD ≤ 20 mg / L, SS≤ 20 mg / L, NH3-N≤15 mg / L. And the removal effect of NH3-N has changed obviously which removal rate increased by 49.4%.
