城市污泥中重金属形态及资源化可行性分析
Form of Heavy Metals in Sewage Sludge and Resource Feasibility in Southern City
摘要
Abstract
The content and form distribution of heavy metals (Cu,Zn,Ni,Pb,Cd,Cr)from sewage sludge in six wastewater treatment plants in a southern city of China were investigated.The maximum amount of sewage sludge which could be applied to agricultural soil and brick was also calculated.Results revealed that Zn and Cr existed mainly in una-vailable form,and Cu was in a state of potentially effective and unavailable fraction.The effective proportions of Pb,Ni and Cd were larger than other metals.As calculated by the static environmental capacity of latosolic red solid of the city, the main detected harmful heavy metal was Cd in the course of agriculture utilization of sludge.The maximum application amount of sludge from various sources were significantly different.Therefore,we suggested that the content of Cd in sewage sludge could be used as a reference index,which was used for calculating the maximal application rate in the con-trol of application rate of sludge for agricultural land,and for the protection of solid environment.As calculated by the addition ratio of the sewage sludge in the brick,the main control index was Cu in the E wastewater treatment plant, meanwhile Cr was selected as the dangerous heavy metal in the other five wastewater treatment plants.关键词
