氧化沟曝气与土壤植物系统处理油田污水

Combine Aerated Oxidation Channel with Soil and Plants to Treat Wastewater from Living in Oilfield

中原油田污水对环境污染严重,结合污水的特点,探索出氧化沟曝气与土壤植物系统结合的处理方案。过程由三级处理单元组成。一级单元除去大部分泥沙、悬浮物、漂浮物等固体物质;二级单元有机物借助好氧微生物和污水底部厌氧微生物作用而分解;三级单元利用土地以及其中的微生物和植物根系对污染物的分解、吸收能力来处理废水。上述过程的处理效率达80%以上。

Wastewater in Zhongyuan Oilfield severely pollutes the surroundings Considered of its characteristic, treatment system of wastewater, which combined aerated oxidation channel with soil and plants, has been created This system is composed of three units In the first unit most of silt, suspended and floating matters, other solids and etc are removed In the second unit aerobic and anaerobic microorganism decomposes organic matters By using the decomposition and absorbability of soil, microorganism, and root system, wastewater is treated in the third unit The efficiency of above treatment system can reach higher than 80%
