- 摘要:
- 随着铸造业的发展，铸造废砂排放日益增多，现有堆存处理不仅占用大量土地，还带来了严重的环境污染
问题。 本文从铸造废砂行业发展背景、资源化利用途径及其存在的问题入手，对宁波市铸造废砂的现状进行分析，针对
铸造废砂排放量巨大、成分复杂、资源化利用低及监管效能低下等特点提出相应的发展建议，即：通过“强链、延链与补
链”方式，建立多产业协同的铸造废砂循环利用系统，使“绿色+”成为新的经济增长点；结合“数字赋能”发展趋势，搭建
铸造废砂数据库和信息共享服务系统，提高监管效能并服务产业，全链条提升废砂资源化利用率。
With the development of foundry industry, the discharge of foundry waste sand is increasing day by day. The existing stockpiling treatment not only takes up a lot of land, but also brings serious environmental pollution. In this paper, starting with the development background of foundry waste sand industry, the way of resource utilization and existing problems, the present situation of foundry waste sand in Ningbo was analyzed. In view of the characteristics of foundry waste sand, such as huge discharge, complex composition, low resource utilization and low supervision efficiency, the corresponding development suggestions are put forward, that is, through “strong chain, extended chain and complementary chain” mode, to establish a multi-industry collaborative foundry waste sand recycling system, and make “green +” become a new economic growth point; combined with the development trend of “digital empowerment”, the foundry waste sand database and information sharing service system are set up to improve the supervision efficiency and serve the industry, and improve the utilization rate of waste sand resources in the whole chain.
