制造业)高度集中在佐治亚州西北部库萨河及其支流(康纳索加河、库萨瓦特河和奥斯塔瑙拉河)提供服务的地区。所有的城市和工业废物都排放到这个流域，多尔顿、卡尔霍恩和罗马等城市的供水都来自这个流域。工业的规模、废物处理厂运行和运行中的困难以及供水和废水中纺织加工化学品的浓度1已知许多工业排放到城市污水系统对废物处理设施有不良影响，特别是在生物抑制方面。关于特定纺织加工化学品对生物处理的影响或对这些成分的微生物利用(生物分级)的影响，人们知之甚少。已预料到氯化联苯的存在，并随后在初步研究中证实，由于已知的毒性，氯化联苯可能会干扰废物处理设施的运行。本文介绍了有关联苯、乙基己醇、甲基萘、甲基苯并噻唑、壬基酚、三氯苯和Aroclor 1254[一种商品的多氯联苯混合物]对微生物的分级和抑制作用的一系列研究。鱼的生物化验数据也包括在内。
manufacturing) industry is highly concentrated in an area of northwest Georgia served by the Coosa River and its tributaries (the Conasauga, Coosawattee, and Oostanaula rivers ). All municipal and industrial wastes are discharged into, and the water supplies for the cities of Dalton, Calhoun, and Rome are taken from, this river basin. The magnitude of the indus try, difficulties in waste treatment plant operation and plant performance, and the concentrations of textile-processing chem icals in water supplies and wastewaters are described and presented in a separate re port.1 Many industrial discharges into mu nicipal sewerage systems are known to have undesirable effects on waste treatment facilities, particularly in terms of biological inhibition. Very little was known concern ing the effects of specific textile-processing chemicals on biological treatment or on the microbial utilization (biod?gradation) of these components. It was anticipated and subsequently confirmed in preliminary studies that chlorinated biphenyls were present which, due to their known toxicity, may be interfering with waste treatment facilities operation. This report deals with a series of studies relating to microbial biod?gradation of and inhibition of microorganisms by the follow ing: biphenyl, ethyl hexanol, methyl naph thalene, methyl benzthiazole, nonylphenol, trichlorobenzene, and Aroclor 1254 [a com mercial mixture of polychlorinated bi phenyls (pcb)]. Fish bioassay data are also included.
