煤渣吸附水中BHC(六氯环己烷)的条件实验研究

Experimental research based on the condition of cinder absorbing BHC(benzenehexachloride) from water

以GC-MS为分析手段,利用一定量预处理后的工业废弃物煤渣,通过实验得出煤渣吸附水中BHC的最佳条件为:pH值5,温度15℃。煤渣粒径的减小、用量的增加以及延长煤渣与水中BHC的接触时间均能增加煤渣对水中BHC的吸附量,在最佳条件下,每克煤渣对水中BHC的吸附量能达到354.22μg以上。通过利用煤渣处理安图水库水样结果表明,用煤渣处理含BHC的污染水,是一种较为理想的环境治理方法。

Based on the analysis of GC-MS, making use of some industrial waste cinder which has been pretreated with, the optimal condition that cinder absorb BHC from water is as follows: pH value is 5 and temperature is 15℃, the decrease of cinder size, the increase of quantity of the cinder, and prolong the time that cinders contact BHC in water, all of the above can increase the absorbing rate that cinder absorb BHC from water. Under the optimal condition, the absorbing rate for per gramme cinders absorbing BHC from water can reach to the amount over 354.22 μg. It is shows that dealing with the wastewater of BHC with cider is an ideal way for environmental protection, acording to the results from a case study of Antu Reservior.
