Flavour Industry Wastewater Management Case Study
Water Pollution Research Department, National Research Center, Tahrir street,Dokki,Cairo, Egypt
Summary. This study is carried out to propose an appropriate treatment technology for wastewater discharged from a flavor production factory. Industrial wastewater discharged from this factory ranges between 50-70 m3 /d with an average value of 60 m3 /d. The major source of pollution in this factory is due to cleaning of the vessels therefore the treatment has been carried out on the end-of pipe wastewater. The wastewater is characterized by high values of COD, BOD, TSS and Oil and grease 4646, 2298, 1790 and 626 mg/l respectively. Primary sedimentation of the wastewater for four hours reduced the COD, BOD, TSS and Oil and grease by 43, 47, 80 and 74%, respectively. For the treatment of the produced wastewater, the biological treatment process such as activated sludge, rotating biological contactor (RBC), up-flow anaerobic sludge bed reactor (UASB) have been selected. The results from each treatment process proved to be efficient for the treatment of such wastewater. The treated wastewater characteristics are in compliance with the Egyptian law which regulates the discharge of industrial wastewater to the sewerage system. The RBC was selected and installed by the factory as it has the advantage of low operating and maintenance costs. The factory RBC performance was monitored; characteristics of the treated effluent in terms of oil and grease, COD, BOD and TSS were 27, 362, 139 and 95 mg/l, respectively.
香精工业废水管理案例研究
水污染研究部,国家工程研究中心,Tahrir街,Dokki,开罗,埃及
综述:
本研究对香精生产工厂所排放废水提出一项适当的处理技术.这家工厂工业废水的排放量介于50-70立方米/天,平均值为60立方米/ 天.该工厂的主要污染源是由于器具的清洗,因此治理在污水管道的末端进行.该废水的特点是COD,BOD,TSS和油脂含量高,分别为4646,2298,1790和626毫克/升.废水的主要沉淀物四个小时后分别减少COD,BOD,TSS和油脂百分率为43,47,80和74%.对于产生的废水,生物处理过程如活性污泥法,生物转盘法,升流式厌氧污泥床反应器(UASB反应器)已被选用.各处理过程的结果被证明是对此类废水的有效处理.经处理后的废水特性符合埃及工业废水排放到污水系统的法律规定.生物转盘法由工厂选用和安装,因为它具有运行和维护成本低的优势.工厂生物转盘法的性能经监测;经过处理的排放污水的油脂,COD,BOD还有TSS含量分别为27,362,139和95毫克/升.
