负压膜封闭技术在土壤修复项目中的应用

Application of Technology of Negative Pressure Membrane Structure for Soil Remediation

首钢土壤修复项目2016年6月建成投产,采用负压膜封闭技术建设的封闭料场(简称“负压气膜大棚”)作为其中一个作业单元,用于污染土的存储、预处理、上料作业及修复后合格土的中转暂存。负压气膜大棚长度为135 m,跨度为60 m,净空高度为20 m,由网壳支撑体系,膜结构屋面,智能管理、控制系统,出入门系统,送风系统,尾气净化处理系统,安全监测系统,监控系统,照明系统等组成。目前,负压气膜大棚已经通过北京市环保部门组织的验收,成为我国第一座实现无废气泄漏、地面抗渗漏、可以全天候作业的环保型负压气膜大棚,负压膜封闭技术将会在我国污染土壤的治理与修复中得到推广应用。

In June 2016, the soil remediation project has been built and put into production at Shougang Plant. As a work unit, which is using the technology of negative pressure membrane structure, closed yard can be used for storage, pretreat and load of contaminated soil, it also can be used for temporarily store and transfer of qualified soil. The yard is 135 m long and 60 m wide, and 20 m high, includes grids structures, membrane structure roof, intelligent management, control management, door system, air supply system, exhaust gas purification system, safety monitoring system, monitoring system, lighting system and so on. At present, this yard has been accepted by Beijing environmental authorities. It is the first environmental negative pressure membrane structure yard, which can reach none exhaust gas leak, none ground leak, all weather operation. This technology has a wide range of applications in the contaminated soil remediation in the near future.
