马鞍山市某沿湖区域固体废物危害性研究

Study on the Harmfulness of Solid Waste in a Lake Area of Maanshan City

马鞍山市某沿湖区域堆存有大量的固体废物,为鉴别其危险性,进行了危险特性分析研究。结果表明,其浸出液腐蚀性不在标准规定的危险废物限值范围内,总铜、总铅、总锌、总镉、总镍、总砷、总铬、六价铬、总银、总硒、总汞、总铍、总锰、氟化物均未超出国标允许排放浓度(一级标准)限值,表明该固体废物属于第Ⅱ类一般工业固体废物。

There is a large amount of solid waste piled up in a lake area in Maanshan city.In order to identify its danger,the risk characteristics were analyzed and studied.The results show that the corrosivity of leaching solution is not within the limits of hazardous waste specified in the standard,and the total cop⁃per,total lead,total zinc,total cadmium,total nickel,total arsenic,total chromium,hexavalent chromium,total silver,total selenium,total mercury,total beryllium,total manganese and fluoride all do not exceed the limits of allowable discharge concentration(first class standard)of the national standard,which indicates that the solid waste belongs to the second class general industrial solid waste.
