摘要
通过对废纸脱墨污泥进行重金属含量及化学形态分析、有机污染物种类及含量等分析,研究其所含主要毒性物质及其对环境的影响。污泥中Cu和As的含量分别是269.0,113.7 mg/kg,会导致环境污染;Cu和As均以残渣态为主,分别为94.76%和100%,稳定性较高;污泥主要含有2,2’,5,5’-四甲基-1,1’-联二苯、邻苯二甲酸二异辛酯,含量分别为0.223%、0.165%,其生物毒性及其对生态环境和人体的危害是不容忽视的。
The analysis of the contents of heavy metals in deinking sludge of waste paper which included their chemical forms,and the type and contents of organic pollutants were measured carefully to study main toxic substances and their influences to the environment.The contents of Cu and As were 269.0mg /kg and 113.7mg /kg respectively and this would result in the environmental pollution.The chemical forms of Cu and As were almost residual.The proportions of residual form were 94.76% and 100% respectively;There were 1,1-Biphenyl,2,2',5,5'-tetramethyl and Di(2-ethylhexyl) phthalate in this kind of sludge.The contents of them were 0.223% and 0.165% respectively.The two sorts of organic pollutants was harmful to the ecological environment and humans because of their biological toxicity.
