Response Relationship Analysis of Hydro-Chemical Factor during Cleanse Process of Scoria for Petroleum Hydrocarbons in Groundwater
摘要
Abstract
Abundant, economic and eco-safe scoria was used to decontaminate groundwater contaminated by petroleum.This essay shows the response relationship between its decontamination process and hydrochemistry factors.The main investigation hydro-chemical factors included Fe2 + , Fe3 + ,Mn2 + ,SO 2 -4 ,NH +4 ,Ca2 + ,Mg2 + ,NO -3 ,NO -2 and so on.The results show that scoria adsorb petroleum hydrocarbons (total petroleum hydrocarbon,TPH )in the water:it is not affected by Mn2 + ,SO 2 -4 ,Ca2 + ,NH +4 ,but affected by Fe2 + ,Fe3 + ,Mg2 + ,NO -2 ,NO -3 .The Fe2 + ,Fe3 + ,Mg2 + and NO -2 have the inhibition effect on the adsorption of the scoria for TPH,while NO -3 has the promotion effect on the adsorption of the scoria for TPH.In the purification process of scoria for TPH,it can simultaneously remove all the ions.The removal rate of Ca2 + is between 42% to 56%,those of SO 2 -4 ,Mg2 + ,NH +4 are between 60% to 80%,while those of Fe2 + ,NO -3 are greater than 80%,and Fe3 + ,Mn2 + ,NO -2 are almost completely removed and the removed rates are more than 95%.关键词
