In view of solving the pollution problem of waste alkali liquor in oil refineries, 5 optimized strains were screened and domesticated from refinery sludge for the degradation of alkaline wastewater. It can be seen that the degradation performance of these 5 strains was significant by comparing the chemical oxygen demand value.

针对炼油厂高浓度废碱液污染大、难处理的问题，从污泥中经过驯化分离，筛选出5株用于废碱液降解的优势菌，经过对5株菌降解化学耗氧量的比较，优势菌对废碱液的降解效果明显。

Mercury contents in the polluted rivers and soils are usually high when it is high in the goldmine wastewater and tailings debris. Because the environment polluted by mercury is very difficult to recover and some biology can highly enrich mercury in their bodies, it is necessary to strengthen manage the tailings debris and ban amalgamation process and the low technique individual gold digger.

金矿废水废渣中汞含量高，则受其污染的河流和土壤中汞含量也相应较高，由于环境汞污染的永久性和难修复性，以及某些生物对环境中的汞有富集放大作用，因此除了加强对已产生的尾矿渣的管理外，还应该坚决取缔混汞法和技术水平低下的个体采金行为。
