生化部分采用改造的多点进水的运行方式,工艺流程见如下,处理后出水可达到国家石油化工行业污水排放一级标准. 格栅―调节池―平流式隔油池―混合反应池―气浮池―生物接触氧化池―二沉池―达标排放 本设计说明书较全面地叙述了设计方案的选择与论证、处理构筑物的设计计算、处理站平面布置和高程布置及工程概算等内容. 关键词:炼油污水,处理站,隔油,生物接触氧化 refinery process design sewage treatment : The chemical industry, oil refinery production and refinery wastewater, generated during the operation of the contaminated water can not be directly used, it is the important part of industrial wastewater.Refining industry is more serious environmental pollution, the industry, from raw materials to product, from production to use, there are factors that cause environmentahttp://www.mianfeiwendang.com/doc/f2707a11289f814cd8c11d4dl pollution. the impact of production processes and products, oil refining wastewater quality and quantity are complex, with different concentrations of organic pollutants, is one of intractable industrial waste.Currently, the domestic oil refining to chemical and biological wastewater treatment methods, supplemented by some physical methods such as flocculation, precipitation. process design for refinery effluent water quality, water features, and strive to achieve economy, efficiency, using the traditional, a successful design and operation experience of the activated sludge method, supplemented by physical methods;

biochemical some more progress with transformation run the water, see the following process, the treated effluent can reach the national level, the petrochemical industry effluent discharge standards. - Adjustment Pool - Rectangular grease trap - Mixed reaction cell - flotation tankhttp://www.mianfeiwendang.com/doc/f2707a11289f814cd8c11d4d - biological contact oxidation pond - the secondary sedimentation tank - discharge standards design specification more comprehensive account of the choice of design and studies, design and calculation processing structure, layout and elevation treatment station layout and the project budget and so on. words: sewage, treatment plant, grease, biological contact oxidation 目录设计说明
