摘要
比较了三沟式氧化沟和双沟式氧化沟在莒县污水厂实际运行的工艺参数、处理效果及经济成本。结果表明:双沟式氧化沟对BOD5、COD和氨氮的去除率分别达到93.3%、88.4%、89.5%,均高于三沟式氧化沟的去除效果;双沟式氧化沟占地面积较三沟式氧化沟小10%,但土建费用较三沟式氧化沟高15%;三沟式氧化沟生物处理部分电耗比双沟式氧化沟高23.7%,但其污泥转输与处置费用较双沟式氧化沟低21.1%。
The operational parameters, treatment efficiency and economic cost of DE oxidation ditch and triple oxidation ditch in Juxian WWTP were compared. The results showed that the removal rates of BOD5 , COD and NH3 - N by DE oxidation ditch were 93.3%, 88.4% and 89.5%, higher than those by triple oxidation ditch. The area of DE oxidation ditch was 10% lower than triple oxidation ditch. However, the construction cost of DE oxidation ditch was 15% higher than triple oxidation ditch. The en- ergy cost of biological treatment unit of triple oxidation ditch was 23.7% higher than that of DE oxidation ditch, but the cost of sludge transportation and disposal was 21.1% lower.
