| 摘 要： | 园林绿地施用污泥(来源于天津纪庄子污水处理厂)堆肥的试验表明:径流和渗滤水中硝酸盐的增加是最主要的污染问题,但污泥堆肥用量控制在50t/hm2以内,不会对地面水和地下水产生不良影响?该厂污泥中的重金属和有机污染物亦不会对径流和渗滤水产生明显不良影响?

| Abstract: | The field experiment was conducted to examine the effects of sludge compost applied to green area on the environment. The results show that increased presence of nitrates in the surface runoff or infiltration of first importance as a factor of pollution. But it would not cause insignificant adverse effect of an application of sludge compost of a rate within the range of 50t/hm 2. The heavy metals and organic contaminants in sludge compost from the Jizhuangzi sewage treatment plant did not cause insignificant adverse effect on surface runoff and infiltrates. |
