摘  要:
分析了皂素废水水质情况,并研究了温度、pH和Co2+、Ni2+、Mg2+、Zn2+等2价金属离子不同组合 对厌氧颗粒污泥活性的影响。结果表明,在30C和进水pH=6的条件下,经升流式厌氧反应器(UASB)驯化后的厌 氧颗粒污泥的活性较高,另外,添加微量元素Co2+、Ni2+、Mg2+和Zn2+,可以显著提高厌氧污泥的生物活性。

摘  要:
The wastewater from saponin production in pharmaceutical industry contains high acidic organic and plenty of carbohydrates. The paper studied the quality of wastewater,analyzed the factors affecting the activity of granular sludge,including temperature,pH and microelements. Experimental results indicated that the granular sludge cultured with UASB would show high and stable activity under the condition of pH 6. 0,30 C. The activity of Granular sludge could be apparently improved when adding Co2+ , Ni2+ , Mg2+,Zn2+.
