Qingtie Pipeline Oil Spill Pollution Ecological Restoration

Shenyang oil and gas branch area of Changtu County,near the sun village oil spill occurred in the vicinity of the oil pipeline.After the oil spill incident,Shenyang oil and gas company invested a lot of manpower and material to repair and emergency treatment,events and their effects are effectively controlled,but there is still a part of the oil into the black mouth river from the oil spill point straight-line distance of about 60 meters.Oil pollution of the hidden,long incubation period,involving a wide range,governance difficulties,the increasingly apparent harm,has become an environmental problem can not be ignored.In order to ensure the spring after ablation and the rainy season arrival of Liaohe River water quality is not affected,eliminate due to leakage and emergency landing loss of oil on soil,rivers,etc.the residual effect of restoration of watershed ecology,there is necessary to repair the damage to the soil and water.The ecological restoration plan construction content mainly consists of four parts,respectively is leakage leakage and pollution heavier regional storm water runoff collecting engineering,in situ remediation of soil engineering,river water ecological restoration engineering dam,river slope ecological slope protection engineering.Microbial remediation of soil contaminated by crude oil and ground surface destruction,soil in situ remediation and restoration of vegetation to prevent soil erosion.Oil spill point,before the river village,old raft soil pollution area take surface rainwater harvesting engineering measures,prevent soil pollution in the residual oil with surface runoff diffusion and into a nearby river water.In situ remediation of soil by plant and microorganism in this region.Slight pollution,slightly polluted soil region to take plant + microbial remediation measures for soil in situ remediation.Moderately polluted soil dosing,solid microbial agent,mild contamination,low degree of soil pollution points twice voted with liquid microbial agent,mild and micro pollution of the regional investment and inoculum concentration and different.River water body restoration with ecological restoration of the dam as the Shenyang oil and gas branch block the oil and sludge and activated carbon dam supplementary measures.Take the stone cage revetment of river slope and hydraulic seeding grass protection of ecological slope protection.
