摘 要:
住房和城乡建设部产品标准《城镇污水处理厂污泥处置 林地用泥质》( CJ / T 362—
2011)
自 2011 年 6 月 1 日起实施。该标准适用于城镇污水处理厂污泥处置时对林地用泥质的要
求,规定了城镇污水处理厂污泥产品林地用的泥质、取样和检测等要求。污泥的林地利用不直接涉
及食物链,因此对重金属、有机污染物等指标的要求比《城镇污水处理厂污泥处置 农用泥质》( CJ /
T 309—2009)
的低。与园林绿化的场地相比,污泥林地用的场地较远离人类活动场所,对污泥中的
一些污染物限值没有《城镇污水处理厂污泥处置 园林绿化用泥质》( CJ 248—2007) 要求的那么高。
对泥质的理化指标( 杂物含量) 也在农用泥质基础上放宽。但考虑到林地用的特殊场合,标准中规
定了施用场地的坡度要求。

Abstract
:
The Disposal of Sludge from Municipal Wastewater Treatment Plant—Quality of Sludge
Used in Forestland
( CJ /T 362 - 2011) comes into effect from June 1,2011. The standard covers re-
quirements for the quality of sludge used in forestland during sludge disposal in municipal wastewater
treatment plants
,and it prescribes requirements for the quality,sampling and testing of sludge used in
forestland. Because the sludge use in forestland does not involve the food chain
,the requirements for
heavy metals and organic pollutants in this standard are lower than those in Disposal of Sludge from Mu-
nicipal Wastewater Treatment Plant—Control Standards for Agricultural Use
( CJ /T 309 - 2009) . Further-
more
,because the site for sludge use in forestland is much farther away from the crowd than the site for
gardens and parks
,the limit values of pollutants in sludge used in forestland are not as strict as those in
Disposal of Sludge from Municipal Wastewater Treatment Plant—Quality of Sludge Used in Gardens and
Parks
( CJ 248 - 2007) . The requirements for physiochemical indexes for the quality of sludge used in
forestland are relaxed on the basis of the quality of sludge for agricultural use. Considering the special
