【摘要】 据矿渣处理含铅废水试验,研究矿渣用量及细度、废水PH、混和反应时间及温度等对除铅效果的影响。结果表明:废水PH值为3～9、P ²⁺为20～800mg/1,按铅/渣质量比为 1/100加入矿渣,去除率达99％且出水pH近中性。更多还原

【Abstract】 According to the experiment of treating wastewater with Pb in by mine-waste the Pb removal offect was studied of mine-waste quantity, fine degree, pH value of wastewater mix-reaction time and tempereture. The result was that when wastewater pH-value 3 - 9, Pb concentration 20 ~ 800 mg/1, input minewaste by Pb/waste 1/100 (quantity ratio),the Pb removal reach 99% and the output water pH value was nearly neutral.更多还原
