摘　　要：砂石加工系统在生产过程中会产生大量含有悬浮物、泥沙等污染物的废水,对环境造成严重影响。本篇文章针对砂石加工系统废水的特点,研究了一种高效、经济、环保的处理工艺。该工艺采用“沉淀+净化+过滤”的组合方式,首先利用积淀池预处理进行沉淀,去除大部分悬浮物,然后经旋流净化进一步降低废水浊度,最后采用板框压滤机进行过滤,使出水达到回用或排放标准。实验结果表明,该工艺对砂石加工废水的悬浮物去除率可达95%以上,出水浊度低于5NTU,能有效去除废水中的污染物,实现废水的达标排放和回用,具有良好的应用前景。The sand and gravel processing system generates a large amount of wastewater containing suspended solids,sediment and other pollutants during the production process,which has a serious impact on the environment.This article focuses on the characteristics of wastewater in sand and gravel processing systems and studies an efficient,economical,and environmentally friendly treatment process.This process adopts a combination of"sedimentation+purification+filtration".Firstly,a sedimentation tank is used for pre-treatment to remove most suspended solids.Then,the wastewater turbidity is further reduced through cyclone purification.Finally,a plate and frame filter press is used for filtration to ensure that the effluent meets the reuse or discharge standards.The experimental results show that the removal rate of suspended solids in sand and gravel processing wastewater by this process can reach over 95%,and the effluent turbidity is less than 5 NTU,which can effectively remove pollutants in the wastewater,achieve standard discharge and reuse of wastewater,and has good application prospects.
