摘要
硼泥复合混凝剂处理大连机车车辆厂含８ｇ／Ｌ左右硅酸根的铸钢废水，最佳投加量为６．６ｇ／Ｌ，去除硅酸根适宜．ｐＨ值为７．２～９．０，当沉降２０ｍｉｎ，硅酸根悬浮物去除率大于９８％，ｐＨ值为８．０～８．５．处理费用低，操作简单．
The method uses boron sludge compound coagulant to treat casting steels wasterwater,which contains about 8 g/L sodium silicate from Dalian Locomotive Plant.The most proper dose of the compound coagulant to remove silicate is 6.6 g/L,pH value 7.2～9.0.After 20 min,the pH value of the solution is around 8.0～ 8.5 and the rate of removing suspended solid exceed 98%. The cost of the method is low,and easy to operate.
