此处,我们来介绍一下我们在英国堆肥场的气味控制方法和改进方案 Let us introduce the projects we have had in composting sites of UK for odor control and our improvement proposal:

起初,我们用的是“外围喷嘴系统”(下图中的兰色点),但是由于气味源的气味没得到很好的控制,加上复杂的风向和气流影响,仅此方法宣告失败 Initially, we had used “perimeter nozzle system”(the blue dots line), but it failed because of the complete wind direction and air currents.

改进方案是 The improvement proposal:

• 用斯瓦特雾炮HF35群,来布设“外围雾炮系统” (如图是;“外围雾炮系统”的布点方案)Use our hurricane cannons to consist of the “perimeter cannon system” (you can see the locations of cannons from the figure)

• 用斯瓦特雾炮HF35D,对工作面进行流动式喷雾处理;Hurricane cannons are used as mobile misting odor control to deal with the working face.

• 在传送带两边,设置喷嘴系统,把生物细菌产品喷到垃圾中去混合,从而抑制气味的产生。One the two sides of the conveyer belt,nozzle system is set to mix the bacterial and enzyme products with the garbage.

以上方案取得了很好的效果,英国国家环保局准备把这一方案定为堆肥厂的统一气味控制标准向全国的堆肥场强制推广。Above proposal has received very good effectiveness. So, the UK EPA has used this proposal as a mandatory standard odor control process to be implemented in all composting commentary in this country.
