“整个化学污染治理过程需要花费1亿元,这些费用在投标之前已经告知投标和最后中
标企业。考虑到治污成本,该地块出让的价格相对较低,万科拿地楼面价仅合1700元/
平方米,而附近房地产开发项目的销售均价达9000元/平方米。”
1700 和 9000 !!!我想很多房地产公司会把注意力投向废弃工业用地,但是国内做
这方面环境评估和治理的力量好像还没有发展起来,市场应该会很热。
懂技术的牛牛们给简单介绍一下这个过程涉及的工序和主要难度。 | h*****k 发帖数: 744 | 2 先测一测污染了多深,对地下水有什么影响,然后把土挖出来,处理完再填回去. In situ
处理很困难,加水,用电化学的方法(具体看是什么污染物了),bioremediation就更慢了.
快一点的方法有...啥也不做,过半年,然后宣布处理完了,开始盖楼. | m*****o 发帖数: 15 | 3 in situ的话没个15-20年时间的monitoring, sampling处理不完。
excavation的话也是治标不治本,挖出来倾倒到landfill处理。
这是需要时间和耐心的,不要光看能挣多少

了.

| E*****P 发帖数: 591 | 5 看起来万科也是走“自然路线”啰。
全挖走倒是相对经济有效的办法,然后把挖出的土当作危险化学品处理? | m********e 发帖数: 177 | 6 Sounds like a good opportunity to initiate some site remediation projects.
CEPA drafted a couple of new standards for soil and groundwater recently,
but I doubt if 万科 can find someone to cleanup to the standard cost-
effectively. For residential development, they should follow more stringent
standards.
140000m^3 soil + unknown groundwater plume, that will cost a fortune and
take a long time.
Also I don't buy that DDT & 六六六 are the only contaminants. That site used
to make pesticides and paints. | a***h 发帖数: 1222 | 7 EPA has poured billions of dollars on site remediation of Superfund sites
with only a handful of them cleaned up.
Basically there is no effective way to clean up soils contaminated by heavy
metal and other nondegradable contaminates.
