    摘要： The present invention involves a persulfate-release material used in the filler of permeable reactive barrier (PRB). This material presents double-layered structure characteristic: inner- and outer-layers are consisted of persulfate, cement, sand and water with different mass ratio. Two different types of moulds are used for the regulation of the shape-of the two-layer structures, which guarantees the stability and reproducibility of its structures and properties. During the whole released process, the released rate become more uniform and stable by the use of this material. During the whole service period, the change of the released rate is very slow, and the service lifetime can be 1-10 years. This invention can both reduce the initial released rate and improve the later released rate, and thus the whole released rate can be more uniform, which can be an important method to promote the efficiency of the persulfate toward engineering application.

    摘要： An in-situ reagents injection system comprises a compressed air storage tank, a remediation reagents storage tank, an injection adjusting valve, an injection pipe, an upper sealing device and a lower sealing device. When the reagents injection is carried out, the compressed air is injected before the remediation reagents is injected, the porosity of the aquifer medium is increased by utilizing the air pressure expansion technology to form a relatively uniform dominant channel, and the remediation reagents is injected to realize uniform and efficient conveying of the reagents. The in-situ reagents injection system and method can make the homogeneous and efficient conveying of the remediation reagents, and ensure the full utilization of the remediation reagents, with low energy consumption of injection equipment, simple process, and flexible operation. The injection is performed in sections from top to bottom according to the steps to improve the in-situ reagents injection efficiency and remediation efficiency.
