Among them, it also accounts for: gas: the pollution incident caused by the combination of the righteous and petroleum hydrocarbons is a big hazard to the environment and human bribery. Therefore, the soil fish is also necessary... And, the above: there is: =, there is no delay, so it is often necessary to have a person to have a main point of saying that the dragon and the sewage are rectified. In the case of chemical oxidation, it is necessary to provide servants and lings for a long time under the surface of the earth. The sulphur is oxidized to gossip! ^, dry agent, chemically promoted: = =: See the injection of chemical oxidants into the surface The method includes: injection well direct injection circulation system and permeability, 'recovery from the sputum, 'mouth wall system, etc.', and the osmotic thumb technology system is the common groundwater remediation developed in recent years at home and abroad. Permeability (10) refers to the installation of the filling system 201125649 in the underground environment and will react with the pollution pure (4). When the contaminated groundwater flows through the permeable wall, it will react with the reaction substance. Degradation. The osmotic remediation system has the following advantages: (1) does not require any mechanical equipment and electricity; (7) can be located at (4) groundwater, without the need to extract and recharge groundwater; (7) no need to redeem organic pollutants Transfer to a gas phase product, thus avoiding the secondary environment > 5 dyeing; (4) for the site that needs long-term remediation can achieve the effect of the local Lulu 3 to save manpower and material resources, so Effectively reduce the cost of remediation. From the above advantages, the benefits of the remediation wall system are completely dependent on the effective release time and concentration of the reaction substance. In the traditional pure (four) pure +, it usually uses slow release substances, such as cement or gypsum. As a coating material/coagulation material, in order to enable a long-term release effect of a reactive substance such as a chemical oxidant or a biological growth substrate.

The preferred embodiment of the present invention can be By controlling the weight ratio of the starch and the particle size thereof, the pore size of the microvoid which may be formed after the starch is wetted by the sustained-release substance 21 is adjusted, thereby controlling the release rate of the reaction substance for the pollution remediation. When the micropores are too large, the release rate of the pollutant remediation reaction substance to the groundwater 31 is too high, so that the effect of long-term release cannot be achieved; on the contrary, if the micropores formed by the starch are too small, the contamination is caused. The rate of release of the reversing reaction substance into the groundwater 31 is too slow, so that its concentration is too low to effectively oxidize the organic contaminants in the groundwater 31. Therefore, in the preferred embodiment of the present invention, the weight ratio of the composition of the poly(tetra), starch, and the pollution-remediation reaction material (e.g., potassium permanganate KMn〇4) must be maintained at 〇5 to 1.25:0.6 to 1G: Within the composition range of G. 2 to 0.3, for example, preferably 1.25 : 1.0 : 0.25, but it may also be 0.75 : 〇 7 : 〇 225 or ι 〇: 〇 · 8 : 0.25 or Μ : 0.9 : 〇.275, etc. In order to facilitate the formation of appropriate microporosity pore size (ie between 1 〇 3 to 1 〇 6 meters). On the other hand, the coating material of the sustained release material 21 of the present invention, that is, poly Caprolactone (PCL), which is inherently biodegradable, does not need to be rectified after the sustained release material 21 is used to form the rectification wall 2 and has completely released the contaminated remediation reactant. The slow release material 21 is removed from the trench 12 of the wall system (7), and the polycaprolactone remaining in the sustained release material 2 is decomposed by the microorganisms in the existing soil, so that no waste is generated, so that the waste can be prevented.

Then, between the 6th and 22nd days, the concentration of the pollutant remediation reaction substance (potassium permanganate) can be as high as 800 to 900 mg/L, which is the peak release period. Subsequently, after about the 34th day, the release concentration of the pollutant remediation reaction substance (potassium permanganate) was again less than 1 GG mg/L, and gradually decreased, but remained above 32 mg/L. After the 66th day, the release concentration drops below 32 mg/L. This B is lower than the effective concentration, but can continue to oxidize and degrade a small amount of organic pollutants until the sustained release substance 21 completely releases the pollution. Use the reaction substance (potassium permanganate). Referring to Figures 1 and 2, the sustained release product of the present embodiment has the following advantages: (1) the amount of loss of the reactant f for the pollution remediation which is effectively reduced with organic pollution = (2) Investment 20 Bu 2::: Transfer the soil and / or groundwater to its cost of extraction, mechanical equipment and electricity; (3) The slow release of 201125649 2! Sustainable use up to 66 (4) The sustained release material 2i completely releases the coating material (polycaprolactone) remaining after the dyeing and remediation reaction material is a biodegradable and recyclable material, so there is no waste With doubts about secondary pollutants. As mentioned above, most of the slow-release substances used in the traditional permeable remediation wall are made of cement or gypsum, but the coated material remains in the field after the release of the reaction substance and cannot be Decomposition or biodegradation by itself, and the formation of solid waste remaining under the surface of the earth, and thus causing secondary pollution in the field, etc., the slow release substances of the present invention in Figures i and 2 are purchased by using polycaprolactone As a coating material, to coat at least one kind of pollution remediation reaction material, the coating material* can be long-term thief to remediate the organic pollutants in the soil and/or groundwater, and the package The covering material itself can also be biodegraded or reused, which not only helps to improve the effect of pollution release, but also reduces the cost of remediation, increasing the convenience of pollution remediation and reducing the cost of pollution remediation. Furthermore, the sustained-release substance of the present invention also makes the powder test as a pore-enhancing material, so that the reaction substance for pollution remediation coated in the coating material can be slowly released outward through the micro-pores formed by the starch, thereby accelerating the advantage. In order to improve the high-acid acid unloading and slow-release, the reaction and the pouring of the same powder with the water body, the micro-pores can also be formed to avoid causing the pores of the groundwater aquifer to block. Although the present invention has been described in detail, it is not intended to limit the invention, and any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
