南极长城站生活污水处理前后的细菌监测

本文报道了 1 990年初南极长城站生活污水处理前和处理后 ,污水排海管道口水样粪大肠菌群和余氯含量的测定结果。结果表明 :在污水处理前 ,粪大肠菌群的数量较高 ,达 2 4 0 0 0 /1 0 0 0 ml,经处理后 ,菌量急剧地降低 ,低于有关水质规定的标准 ;菌量的降低与污水处理的加氯量有关 ,加氯越多 ,菌量下降也越多。余氯浓度过高 ,可能对近海生态造成影响 ,因此在对污水进行有效处理时 ,要尽量注意控制加氯量

BACTERIAL MONITORING BEFORE AND AFTER TREATMENT OF SEWAGE IN THE GREAT WALL STATION,ANTARDTICA

This paper reports the results of determination of fecal coliform bacteria and the content of residual chlorine in water samples collected from the outlet of sewage discharge before and aften treatment of the sewage in the Great Wall Station, Antarctica. Results indicate that before the treatment of sewage the number of fecal coliform bacteria was high, reaching 24000/1,but after treatment the decrease of the number of the coliform bacteria group was related to the addition of chlorine in sewage treatment. The more the addition of chlorine, the more the decrease in the bacterial number. In consideration of the fact that an excess of the concentration of residual chlorine may produce an impact on the nearshore ecology, attention should be paid as far as possible to the control of the quantity of the addition of chlorine in carrying out effective treatment of sewage.
