常温条件下颗粒污泥处理含铅废水

Lead-Containing Waste Water by Using Granular Sludge as a Media at Ambinent Temperature

对未经驯化的颗粒污泥处理含铅废水进行了初步实验研究,结果表明,颗粒污泥对含铅废水具有较高的去除能力,铅去除率在95％以上,颗粒污泥的加入量、废水酸度、沉降时间是影响处理效果的主要因素,通过对20mg/L的含铅试水进行处理,铅达到了排放标准。

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.
