摘　　要：官地电站砂石料生产系统产生的废水主要来自大、中、小石冲洗筛和棒磨机,正常生产所产生的废水量为280～330 m3/h。为了对废水进行处理,使其达标排放,引进了矿山开采中使用的陶瓷过滤机,其工艺流程为:首先,通过刮砂机将废水中的一部分粗砂进行回收;然后,这部分废水与棒磨机的废水一起进入细砂回收车间进行细砂回收;紧接着,废水流入混合池,在混合池内添加絮凝剂后泵送至沉淀池进行石粉沉淀;最后,将沉淀池的石粉浆液泵入陶瓷过滤机,浆液中的水通过陶瓷片的毛细孔吸出,从而达到石粉和水的分离。滤后的水非常清澈,与厢式压滤机相比,不但工作效率高、运行成本低,而且运行效果稳定可靠。The wastewater produced by aggregate processing system of Guandi Hydropower Station mainly comes from large,medium,small stone washing screens and cylinder mills,the quantity of wastewater in a normal production is 280~330 m3/h.In order to meet the discharge standard of wastewater,we introduce the ceramic filter which is used in mining exploitation.The technological process is as follows： recycle coarse sand in wastewater with sand scraper;and this part of wastewater together with the wastewater of the cylinder mill are used for recycling fine sand in recycling workshop;then the wastewater flows into mixing pool and is pumped into settling tank for stone-powder settling after adding flocculants;finally,the settled sandstone slurry is pumped into the ceramic filter to separate stone-powder and water.The water is very clear after filtering.Compared with the chamber filter press,the ceramic filter has the advantages of higher efficiency,lower cost,and more stable operation effect.
