预拌混凝土搅拌站绿色生产技术探讨

Green Production Technology of Ready-mixed Concrete Mixing Station

行业标准《预拌混凝土绿色生产及管理技术规程》JGJ/T328—2014自2014年10月1日开始实施,结合该标准内容对国内4家预拌混凝土搅拌站的粉尘噪声、废水废浆利用情况进行了调研。结果表明,所调研混凝土搅拌站粉尘指标满足标准要求,但生产噪声较大,基本实现了废水废浆的回收利用和集中处理。提出可以从粉尘噪声控制、废水废浆利用、废弃混凝土应用和综合管理措施等4方面实现混凝土绿色生产。

National standard Specification of green production management for ready-mixed concrete has been issued from October 1,2014. According to the specification,dusts,noises and recycling data of waste water and slurry of four ready-mixed concrete mixing stations were studied. The results show that the dusts data can meet the specification while the noises are a little higher. The recycling and disposing of waste water and slurry have been almost achieved. Green production of ready-mixed concrete can be achieved by using following technical measures： control dusts and noise,recycling of waste,waste concrete utilization and effective management.
