高矿化度油田废水污染农田现状调查与评价

Pollution situation of high mineralized waste water in oil field on farmland

  • 摘要: 江汉油田采油井在钻矿和采油时有少量高矿化度废水与石油洒落地面,导致土壤污染,造成农作物减产。对湖北省潜江县周矾农场不同污染程度的旱地农田和水田污染现状及污染物在土壤中的迁移状况进行了调查研究,结果表明,污染农田土壤的主要污染物是氯化物、盐类,其次为石油和Cd。氯化物、盐类污染水田耕层含量高于底层,旱地农田则反之。受污染的土壤肥力下降。

     

    Abstract: In Jianghan oil field,the soil around the oil well has been polluted by high mineralized waste water which comes from drilling well and extracting oil and caused the decrease of the crop yield.The results from the investigation on pollution status of dry land and paddy with different polluted degrees in Qianjiang County show that the main pollutants are chloride and salt as well as cadmium and oils.In the ploughed layer of paddy,chloride and salt content of the top are higher than those of the bottom,which is on the contrary in dry land.All polluted soil fertility was decreased.
