摘 要：为寻觅合适巢湖流域的污泥处置措置体例和知足烧毁矿区泥土修复对无机改进基质的需求，将巢湖市岗岭污水厂脱水污泥、好氧发酵污泥和厌氧消化污泥别离与巢湖市年夜黄山烧毁矿区泥土依照必然比例混匀进行盆栽实验，研究分歧体例处置污泥添加对烧毁矿区泥土的根基理化性质和微生物特征的影响。成果注解：分歧体例处置污泥都可以较着提高烧毁矿区泥土的无机质和氮磷营养含量；pH值有分歧水平的下降；电导率EC值均较着增添,但仍低在动物一般发展限值；同时能够增添泥土微生物量碳氮含量，增进脱氢酶、转化酶、磷酸酶和脲酶的活性。申明三种污泥对烧毁矿区泥土质量具有分歧水平的改良，以好氧发酵污泥的改进结果最好。
要害词：巢湖流域，不变化污泥，烧毁矿区泥土，微生物特征

Abstract：In order to find suitable treatment and disposal methods of sludge and meet the demand of organic improvement matrix for abandoned mining areas soil remediation in Chaohu Lake Basin,apot experiment was conducted to mix the dewatered sludge, aerobic fermentation sludge and anaerobic digestion sludge of Chaohu Gangling Sewage Treatment Plant with the Chaohu Dahuangshan abandoned mining area soil in accordance with a certain proportion, the effects of adding sludge treated by different methods on basic physical and chemical properties and microbial characteristics of abandoned mining areas soil were studied,The results show that: the organic matter, nitrogen and phosphorus nutrients contents of abandoned mining soil can be significantly increased by adding sludge which treated by different ways;the pH values decrease in varying degrees;thevalues of����APP conductivity increased significantly,but it is still below the normal growth limit of plants;at the same time, it can increase soil microbial biomass carbon and nitrogen contents, and can promote the activities of dehydrogenase, invertase, phosphatase and urease.Andthe results show that the abandoned mining areasoil quality are improved by three kinds of sludge in varying degrees,aerobic fermentation sludge has the best improvement effect.
Keywords：chaohu lake basin；stabilized sludge；abandoned mining area soil；microbial characteristics
