The invention discloses a method for the multi-means combined remediation of the
oil pollution soil of alkaline lands, which comprises the following steps that: (1) the thoroughly decomposed
farmyard manure and
calcium superphosphate are spread over the
oil pollution soil of alkaline lands, and a biosurfactant, namely
rhamnolipid with the
mass concentration of 0.3% is sprayed; (2) the
oil pollution soil of alkaline lands is ploughed up, leveled up and irrigated; (3) alfalfa seeds are wrapped by
fungicide which contains oil degradation
bacteria and alfalfa
rhizobium; (4) the alfalfa seeds which are wrapped by the
fungicide are coated; (5) Chinese wild rye seeds are subjected to low-
temperature treatment; (6) the coated alfalfa seeds and the Chinese wild rye seeds after low-
temperature treatment are mixed, and the mixed seeds are sown in the oil
pollution soil of alkaline lands; and (7) field management is carried out after the
seedling emergence. The method can effectively decompose, degrade and absorb
petroleum pollutants in the oil
pollution soil of alkaline lands, and has the characteristics of quick remediation speed, good effect, simplicity in operation, large treatment capacity, easiness for workers to master and the like.
