【摘要】 分析昆明市6个生活污水处理厂污泥的特性。昆明城市污泥含水率、有机质、总氮、总磷含量很高,总钾含量偏低,重金属Cu、Zn、Pb、Cd、As、Hg的含量满足《城镇污水处理厂污泥处置农用泥质》(CJ/T309-2009)、《城镇污水处理厂污泥处置园林绿化》(GB/T23486-2009)以及《城镇污水处理厂污泥处置土地改良》(CJ/T291-2008)要求,昆明城市污泥可以用于园林绿化、矿山废弃地以及农用。更多还原

【Abstract】 Municipal sludge from six wastewater treatment plants of Kunming and characteristics of sludge were studied.The results of experiment showed that water ratio was high and the concentrations of organic material;TN and TP were high enough;the concentration of TK was low;total amount of heavy mentals(Cu,Zn,Pb,Cr,Sn,Hg) was relatively low and was up to Control standards for agriculture use of disposal of sludge from municipal wastewater treatment plant(CJ/T309-2009),quality sludge used in gardens or parks of disposal of sludge from municipal wastewater treatment plant(GB/T23486-2009),sludge quality for land improvement of disposal of sludge from municipal wastewater treatment plant(CJ/T291-2008).And municipal sludge was suggested to be applied in park flower cultivation,in the recovery of the mining area eco-environment and in agriculture.更多还原
