随着医疗机构的飞速发展,医院的污水排放量也逐年增加,排放标准也愈加严格。部分医疗机构配套建设的污水处理站存在着污水工艺设计不合理等问题,使得现有的医院污水处理站不能满足污水量增加或稳定达标排放的要求。生物接触氧化法是处理医院污水极为有效的一种方法。南京某综合性医院新建污水处理站设计规模1 200m3/d,详细论述了该医院污水处理设计中各污水池功能及设计参数,并从污水水质、废气、污泥和噪音方面分别给出了优化措施。根据建设完成后的检测数据:化学需氧量(COD) 42. 94mg/L,余氯6. 29mg/L,p H 7. 2,悬浮物15mg/L,粪大肠菌群数20MPN/L,沙门氏菌未检出。检测结果显示水质良好,生物接触氧化法工艺设计处理污水效果极为有效。 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 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
