加拿大Solinst地下水污染修复系统（Waterloo Emitter 703）
产品名称：地下水污染修复系统
品牌：Solinst
产地：加拿大
型号：703
Waterloo Emitter 旨在帮助 MTBE、BTEX 和其他污染物的原位修复生物降解。它使氧气（或用于厌氧修复的氢气）能够以受控的均匀方式通过硅胶或 LDPE 管扩散。这种简单、低成本的**技术由一个包裹有管道的 PVC 框架组成，该框架可以加压以获得所需的气体扩散传输，适合特定地点的需求。尺寸适用于 2"、4" 和 6"（50、100 和 150 毫米）井，这些装置可以堆叠在井中并从一个井连接到另一个井，以允许气体受控连续扩散到羽流中。
滑铁卢发射器是一种简单、低成本的装置，设计用于控制和均匀释放氧气或其他生物增强改良剂，以促进和维持原位生物修复受污染地下水所需的微生物的生长。
可通过加压硅胶或 LDPE 管将氧气稳定、直接地扩散到含水层中。将氧气持续、一致地释放到管道中会产生理想的浓度梯度，从而驱动这个被动系统，而不会“冒泡”多余的氧气。
发射器非常适合使用氧气对 BTEX 和 MTBE 进行生物修复。扩散过程为好氧生物降解提供了分子氧的即时生物利用度，因此不会发生修正气体的损失。滑铁卢发射器还可以促进理想的非生物反应（pH 调节、水解等）。
随着向地下添加氧气，污染物的微生物生物降解 - 微生物对化学污染物的自然分解 - 得到了加强。补充自然衰减过程的技术由于其加速清理工作的能力而更常用。使用氧气，滑铁卢发射器有可能使清理更快、更有效、更便宜。
地下水污染修复系统703的安装：
如果要使用增强气体进行修复，可以使用中小型气瓶。选择发射管并根据所需的增强气体量设定压力。单个气瓶可用于为串联连接的多个发射器供电。可以通过定期吹扫（每周/每两周）来补充发射器管内的气体，或者可以在系统末端使用针式放气阀，以实现缓慢、持续的补充。
地下水污染修复系统703的应用：
BTEX 和 MTBE 好氧生物修复的氧气释放
用于溶剂厌氧还原脱氯的氢气释放
引入溶解的 SF6、氩气等用作示踪剂
释放 CO2 调节 pH
轻质烷烃释放促进 MTBE 的共代谢生物降解
羽流迁移屏障、初级修复装置或抛光
地下水污染修复系统703的优点：
低成本
稳定释放以保持恒定的微生物活性
易于安装和拆卸
**少的维护和操作工作
没有因“冒泡”而造成的修正损失
没有引入或生产有害物质
无需混合、处理或注入浆液
不需要电
简单的多功能系统：
滑铁卢发射器可用于安装 2"、4" 和 6"（50 毫米、100 毫米和 150 毫米）井。它们可以安装在裸井中，也可以使用沙包永久安装在钻孔或沟槽中。51 " （130 厘米）长的滑铁卢发射器可以单独安装或堆叠安装，以确保完全覆盖污染物羽流。它们在水平应用中也很有效。
因为没有**水头要求，所以发射器在水下任何深度都有效。当与封隔器和/或循环泵一起使用时，影响半径会增加。
滑铁卢发射器独特的扩散技术允许使用几乎任何化学物质作为修正剂来处理受污染的地下水。PVC 框架可插入监测或采样装置，用于在修复过程中观察地下水状况。
经营原则：
滑铁卢发射器由缠绕在 PVC 框架周围的硅胶或聚乙烯管组成。当流体被引入管道时，管道内部和地下水之间会产生浓度梯度。
发射器按照菲克定律工作，扩散将发生，直到管道内外的化学浓度达到平衡。使用 Emitter 技术，氧气（或其他改良剂）不断补充，随着地下水继续在 Emitter 周围流动，平衡永远不会发生。这导致从发射器持续扩散到地下水中。
当向发射器施加气体时，施加压力的增加与将扩散到地下水中的气体量的增加之间存在直接相关性，但是，扩散是允许将修正添加到地下水中的**机制地下水。

英文原文：
The Waterloo Emitter is designed to assist in-situ remedial biodegradation of MTBE, BTEX and other contaminants. It enables oxygen (or hydrogen for anaerobic remediation) to diffuse through silicone or LDPE tubing in a controlled uniform manner. The simple, low-cost, patented technology consists of a PVC frame wrapped with tubing that can be pressurized to obtain the desired diffusive transfer of gas, appropriate to site-specific needs. Sized for 2", 4" and 6" (50, 100 and 150 mm) wells, the units can be stacked in a well and joined from one well to another, to allow the controlled continuous diffusion of gas into the plume.
The Waterloo Emitter is a simple, low cost device designed for the controlled and uniform release of oxygen, or other bioenhancing amendments, to encourage and sustain the growth of microorganisms required for in-situ bioremediation of contaminated groundwater.
The patented technology enables steady, direct diffusion of oxygen into an aquifer through pressurized silicone or LDPE tubing. Continuous, consistent release of oxygen into the tubing creates the ideal concentration gradient driving this passive system, without ‘bubbling off’ excess oxygen.
Emitters are ideal for the bioremediation of BTEX and MTBE using oxygen. The diffusive process provides immediate bioavailability of molecular oxygen for aerobic biodegradation enhancement, therefore no loss of the amendment gas occurs. The Waterloo Emitter can also encourage desirable abiotic reactions (pH adjustment, hydrolysis, etc.).
With the addition of oxygen into the subsurface, microbial biodegradation of pollutants - the natural breakdown of chemical contaminants by microorganisms - is enhanced. Techniques that supplement natural attenuation processes are more commonly being used due to their ability to accelerate cleanup efforts. Using oxygen, the Waterloo Emitter has the potential to make cleanups faster, more effective, and less expensive.
Installation：
If an enhancement gas is to be used for remediation, a small to medium sized gas cylinder can be used. Emitter tubing is selected and pressure is set according to the amount of enhancement gas required. A single gas cylinder can be used to supply multiple Emitters connected in series. Replenishment of the gas inside the Emitter tubing can be accommodated by periodic purging (weekly/bi-weekly), or a needle bleed valve can be used at the end of the system to allow slow, constant replenishment to occur.
Applications：
Oxygen release for aerobic bioremediation of BTEX and MTBE
Hydrogen release for anaerobic reductive dechlorination of solvents
Introduction of dissolved SF6, argon, etc. for use as tracers
Release of CO2 for pH adjustment
Light alkane release to promote co-metabolic biodegradation of MTBE
Plume migration barrier, primary remediation device, or polishing
Advantages：
Low cost
Steady release for constant microbial activity
Easy installation and removal
Minimal maintenance and operating effort
No amendment loss due to ‘bubbling’
No hazardous substances introduced or produced
No slurry to mix, handle or inject
No electricity required
Simple Versatile System：
Waterloo Emitters are available to fit 2", 4" and 6" (50 mm, 100 mm and 150 mm) wells. They can be installed in open wells, or they can be permanently installed with sand packs in boreholes or trenches. The 51" (130 cm) long Waterloo Emitters can be installed individually or stacked one on top of another, to ensure full coverage of the contaminant plume. They are also effective in horizontal applications.
Because there is no minimum hydraulic head required, the Emitters are effective at any depth below water. When used in conjunction with packers and/or circulating pumps, the radius of influence is increased.
The Waterloo Emitter’s unique diffusive technology allows for the use of almost any chemical as an amendment to treat contaminated groundwater. The PVC frame accommodates the insertion of monitoring or sampling devices for observing groundwater conditions during the remediation process.
Operating Principles：
The Waterloo Emitter consists of silicone or polyethylene tubing coiled around a PVC frame. When a fluid is introduced into the tubing a concentration gradient is created between the inside of the tubing and the groundwater.
The Emitter works in accordance with Fick’s Law, whereby diffusion will occur until there is equilibration in chemical concentration inside and outside of the tubing. With the Emitter technology, the oxygen (or other amendment) is replenished continuously, and as groundwater continues to flow around the Emitter, equilibration never occurs. This results in continuous diffusion from the Emitter into the groundwater.
When a gas is applied to the Emitter there is a direct correlation between an increase in applied pressure and an increase in the amount of gas that will diffuse into the groundwater, however, diffusion is the only mechanism that allows the amendment to be added to the groundwater.
