钻井泥浆和消油剂对合浦珠母贝的急性毒性效应

采用96h急性毒性试验配合滤食率和微核检测等方法，比较了石油勘探开发用3种钻井泥浆和3种消油剂对合浦珠母贝成贝急性毒性效应。实验结果表明：3种钻井泥浆对合浦珠母贝的半致死浓度均大于10^5mg/L；3种消油剂的半致死浓度分别为1047、5011和2630mg/L；滤食率与钻井泥浆和消油剂的浓度呈负相关；微核细胞率则与之呈正相关。     

炼油厂废碱液治理技术的研究

针对炼油厂废碱液存在的问题，研究一种新处理技术—溶剂萃取、破乳和臭氧氧化。为了解不同水质、ｐＨ值、温度的影响而进行试验研究，并获得了最佳操作参数。试验结果表明该技术在脱酚、除油、脱色脱臭方面是一种有效方法。

Acid resistance of methanogenic bacteria in a two-stage anaerobic process treating high concentration methanol Wastewater

In this study, the two-stage upflow anaerobic sludge blanket (UASB) system and batch experiments were employed to evaluate the performance of anaerobic digestion for the treatment of high concentration methanol wastewater. The acid resistance of granular sludge and methanogenic bacteria and their metabolizing activity were investigated. The results show that the pH of the first UASB changed from 4.9 to 5.8 and 5.5 to 6.2 for the second reactor. Apparently, these were not the advisable pH levels that common methanogenic bacteria could accept. The methanogenic bacteria of the system, viz. Methanosarcina barkeri, had some acid resistance and could still degrade methanol at pH 5.0. If the methanogenic bacteria were trained further, their acid resistance would be improved somewhat. Granular sludge of the system could protect the methanogenic bacteria within its body against the impact of the acidic environment and make them degrade methanol at pH 4.5. The performance of granular sludge was attributed to its structure, bacteria species, and the distribution of bacterium inside the granule.

清洁生产是发展云南磷肥工业的必由之路

云南磷矿储量占全国总储量的１９．１３％，将建成全国最大的磷化工基地。造成磷肥工业污染问题的原因一是矿物原料品位低，二是高污染的原料路线，三是非经济生产规模，四是落后的生产管理。要合理有效地利用资源，要使环境能够承载，就必须推行清洁生产，这是云南磷肥工业可持续发展的必由之路。
