Evaluation of Manure Treatment System for Livestock Operations

粪便的管理是当今农业面临的最困难、最昂贵、最具局限性的问题之一。这一问题在与封闭动物饲养业务（cafo）有关的农业部门中尤其普遍，例如用于奶牛和猪的饲养业务。通常，粪便被储存在土池塘或泻湖中，然后用于灌溉（土地扩张）。用于控制气味的封闭式储存和处理设施，如市政处理厂所使用的设施，过于昂贵，不适合农业操作。LWR确定了全国范围内对处理CAFO废物的经济和环境过程的需求，并开发了粪肥处理系统。这种废物处理系统消除了对粪便储存泻湖的依赖，从而减少了令人反感的气味，以及有害污染物，病原体和温室气体的排放。LWR粪肥处理系统生产干净的水，同时通过将牲畜粪便中的有价值的营养物质浓缩成可用的肥料产品来回收它们。在NSERC的支持下，来自Olds学院的农业专家将对新开发的LWR技术进行样本分析和第三方审查。他们的报告将强调必要的改进和/或识别系统中的任何弱点。然后，LWR将能够向畜牧业提供这项技术，并帮助农民创建一个环境可持续的市场。

The management of manure is one of the most difficult, expensive and potentially limiting problems facing the agricultural industry today. This problem is particularly prevalent among that portion of the agricultural industry which pertains to confined animal feeding operations (CAFOs), such as those used for dairy and swine. Typically the manure is stored in earthen ponds or lagoons and then used for irrigation (land spreading). Enclosed storage and treatment facilities for odour control, such as those used at municipal treatment plants, are too expensive to be practical for an agricultural operation. LWR identified a nation-wide need for an economical and environmental process for handling waste from CAFO's and responded with the development of a Manure Treatment System. This waste treatment system eliminates the reliance on manure storage lagoons which in turn reduces offensive odours, as well as the discharge of harmful contaminants, pathogens and greenhouse gases. The LWR Manure Treatment System produces clean water while recovering the valuable nutrients found in livestock waste by concentrating them into a useable fertilizer product. With the support of NSERC the agriculture specialists from Olds College will perform sample analysis and third party review of the newly developed LWR technology. Their report will highlight improvements necessary and/or identify any weaknesses in the system. LWR will then be able to provide this technology to the livestock industry and assist farmers in creating an environmentally sustainable marketplace.
