Lead-Containing Waste Water by Using Granular Sludge as a Media at Ambinent Temperature
-
摘要: 對未經馴化的顆粒污泥處理含鉛廢水進行了初步實驗研究,結果表明,顆粒污泥對含鉛廢水具有較高的去除能力,鉛去除率在95%以上,顆粒污泥的加入量、廢水酸度、沉降時間是影響處理效果的主要因素,通過對20mg/L的含鉛試水進行處理,鉛達到了排放標準。Abstract: The experiment was carried out to investigate the possibility of removing soluble lead from lead-containing waste water by using granular sludge as a media. The results show that granular sludge has a good ability to remove lead from lead-containing waste water. The removing rate can be above 95%. Sludge content, pH value and sedimental time are major factors which affect the treating results of lead-containing water. With a initial lead content of 20 mg/L, the quality of the treated water can reach Chinese national standard of discharging.
