1980年初,铜官山铜矿对工业废水的处理方法进行研究,同时,利用废水进行选矿试验,以便为废水处理设计提供资料。现在,该项试验成果已用于废水处理工程初步设计和施工设计。(一)废水性质铜官山铜矿每天排出的选矿废水9300吨,中性;矿坑水12000吨,pH值5。两种废水的水质如表1。(二)废水处理试验作者研究了石灰和3号凝聚剂对废水澄清的影响。当加入石灰300(毫克/升)处理选矿废水时,5分钟后澄清水固体含量降至150(毫克/升)。当加入3号凝聚剂10(毫克/升)处理矿坑水时,5分钟后澄清水中固体含量也降至190
In early 1980, Tongguan Mountain Copper Mine on the industrial wastewater treatment methods, while the use of waste water dressing test to provide information for wastewater treatment design. Now, the test results have been used for wastewater treatment project preliminary design and construction design. (A) the nature of wastewater Tongguan Mountain Copper Mine discharge of 9300 tons of mineral processing waste each day, neutral; pit water 12000 tons, pH value of 5. The water quality of the two kinds of wastewater is shown in Table 1. (B) Wastewater Treatment Experiment The authors studied the impact of lime and No. 3 coagulant on the clarification of wastewater. The clarified water solids content dropped to 150 (milligrams / liter) after 5 minutes when the mineral waste was treated with lime 300 (mg / l). When adding No. 3 coagulant 10 (mg / l) treatment of pit water, after 5 minutes the solids content of clear water also dropped to 190
