文章对南方某千万吨炼油厂污水处理场受高浓度甲醇污水冲击进行了总结分析,得出污水处理场受冲击的主要原因是:储运罐区在甲醇泵检修过程中,因管理不到位导致甲醇泄漏进入罐区的污水预处理站 六,并将含有高浓度甲醇的污水排入污水处理场及加氢型酸性水汽提装置,引起含油污水和加氢型净化水的COD异常升高,最终进入污水处理场并造成冲击。经过全面系统排查,梳理了炼油厂需重点管控的甲醇、环丁砜、MDEA等废水污染物及产生部位,并提出通过开展检维修作业风险识别、完善污水排放监测和报告制度、强化污水处理操作人员培训、对各股污水设置在线监测等源头控制对策,以加强过程污水排放管控,避免类似情况再次发生,对其他炼油厂具有一定的借鉴意义。 相似文献

大庆炼化公司从单一化工污水深度处理及回收利用发展为炼油、化工、生活污水统一处理和回用于循环水,既充分利用了现有污水处理场的处理余量,同时由于生活污水中含有比例适当的微生物需要的营养物质,对炼油和化工污水起到补充和稀释作用。这种处理方法既降低了工业污水对污水处理场的冲击,又起到了稳定水质的作用。 相似文献

工业污水可生物降解性评价方法研究 总被引:3,自引:0,他引:3
针对生化系统经常遭受异常进水或毒性物质冲击的情况,提出了以耗氧速率(OUR)和相对耗氧速率(SOUR)快速评价污水可生物降解性的方法,以提高活性污泥系统的处理效率和运行管理水平。试验结果表明:OUR和SOUR对异常pH值水质条件以及苯酚、甲醛和甲醇等毒性物质的存在都非常敏感。对于大庆石化公司水气厂化工污水处理场的活性污泥来说,甲醛对微生物的毒性最强,甲醇次之,而苯酚则最弱。化工污水处理场活性污泥对三者的允许浓度分别为70、170、350 mg/L。 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献

人类社会从农业文明时代的崇俭消费模式到工业文明时代的高消费、浪费型消费、过度消费等不合理消费模式的发展过程中产生了严重的全球性环境污染和破坏,能源、土地、淡水等资源性产品供给日益趋紧约束.生态文明型消费模式所具有的适度消费、公平消费和责任消费等内在规定性及其发挥的重要作用说明它是资源性供给紧约束条件下有利于能源资源节约和生态环境保护的居民消费模式.为了适应21世纪生态文明时代人与自然和谐发展的客观要求,突破消费增长、经济发展与资源性供给紧约束之间的发展困境要求我们必须从政府、企业和消费者等三个层面构建生态文明型消费模式. 相似文献

Removal of cadmium from aqueous solutions using 20 species of plant leaves and combinations of these leaves have been studied. Several factors affecting the removal efficiency have been studied. The most efficient types of plant leaves for the removal of cadmium are those of styrax, plum, pomegranate and walnut. The interaction effect of the combined leaf samples on the efficiency of removal of cadmium has been found to be additive in combinations involving styrax plant leaves but seems to be antagonistic in all other combinations. The optimum experimental conditions for removal of cadmium have been found to be at pH 4.1, using high concentrations of naturally dried plant leaves, using ground leaves and to remove cadmium from agitated aqueous solutions. The percentage of metal removed at an initial cadmium concentration of 10mg/l by the most efficient types of leaves have been found to be 85% for styrax leaves, 85% for plum leaves, 80% for pomegranate leaves, 78% for walnut leaves and 77% for meddler leaves. The presence of foreign ions or complexing agents has been found to reduce the efficiency of removal of cadmium by plant leaves. About 80-85% of the cadmium in charged plant leaves has been released under the influence of changing the pH of the solution, addition of competing ions and the addition of EDTA. The results of removal of cadmium by plant leaves have been found to follow the Freundlich adsorption isotherm, first-order reaction with respect to cadmium and to have intra-pore diffusion as the rate-limiting step. 相似文献
