Immobilized biocatalysts on selected filter media to control odour emissions from wastewater treatment and composting facilities

由于市民抱怨本港空气质素欠佳，污水及固体废物处理行业普遍面临气味问题。虽然气味去除技术已经存在，但它们遇到了许多问题。该技术不需要使用刺激性化学物质，这意味着无需处理废水流。这将对减少排放到环境中的化学品产生影响，防止对土地和水资源造成不必要的污染。该技术对空间的要求较低，将腾出以前用于大型生物过滤器的土地，用于其他用途，包括市政设施。

Odour is one of the common problems faced by wastewater and solid waste industries as a result of public complaints about poor local air quality. Although odour removal technologies exist, they encounter a number of problems. The lack of harsh chemicals required for the proposed technology means there is no wastewater stream to treat. This will have an impact on the reduction of chemicals disposed to the environment, preventing unnecessary contamination of land and water resources. The lower space requirement of the technology will free up land, formerly required for large biofilters, for other uses including civic amenities.
