发光菌毒性试验在项目竣工环保验收监测中的应用

某敏感化工技改项目曾因超标排污引发跨地区厂群纠纷被责令停产整改,为考察该项目整改后废水处理设施的运行效果,保障水生生物安全,在该项目竣工环境保护验收监测时,采用发光细菌毒性试验检测废水的急性毒性.结果表明,达标排放的废水对生物的急性毒性为低毒,试验结果与常规验收监测结果有可比性,发光细菌毒性试验可用于必须公示的敏感项目竣工环境保护验收监测.

Application of photobacterium phosphoreum toxicity test on the environmental protection acceptance monitoring at project completion

One sensitive chemical technical renovation project was forced to suspend production and rectify, due to its over_standard pullutant discharge, which had aroused trans_regional plant-civilian disputes. To survey the project's wastewater treatment facility's running effect after rectification and to ensure the safety of hydrobiont, the photobacterium phosphoreum toxicity test was conducted to detect the acute toxicity of wastewater during the enviornmental protection acceptance monitoring at project completion. The study showed that its wastewater which up to the discharge standard, had little acute toxicity on hydrobiont and the result of the test was comparable with that of the conventional tests. It suggested that the test could be applied in the environmental protection acceptance monitoring for such projects that should be open to the public.
