摘要
为了促进白云鄂博矿区固废资源化利用及矿山生态环境修复,针对矿区气候条件特殊,高寒、干旱、多风、缺少治理表土等问题,研究利用矿区尾砂和污水处理厂发酵污泥为原料进行土壤重构试验,并探究不同配比的重构土土壤特性和其中植物的生长情况。试验结果表明:利用矿区尾砂和污水处理厂的发酵污泥可制备重构土,随着污泥含量的提高,重构土土壤容重有效降低,有机质含量明显提高,土壤中的N、P等营养元素含量提高,有利于植物的生长和植被的恢复。
In order to promote the utilization of solid waste resources and the restoration of mine eco⁃logical environment in Bayan Obo mining area,aiming at the problems of special climatic conditions,cold,drought,windy and lack of topsoil treatment in the mining area,the soil reconstruction test is carried out by using the tailings of the mining area and the fermented sludge of the sewage treatment plant as raw materi⁃als,and the characteristics of the reconstructed soil with different ratios and the growth of the plants are ex⁃plored.The test results show that the reconstructed soil can be prepared by using the tailings of the mining ar⁃ea and the fermented sludge of the sewage treatment plant.With the increase of the sludge content,the soil bulk density of the reconstructed soil is effectively reduced,the organic matter content is significantly in⁃creased,and the content of N,P and other nutrients in the soil is increased,which is conducive to the growth of plants and the restoration of vegetation.
