Movable integrated transformer substation accident oil tank oil-containing wastewater treatment device

Abstract

The invention discloses a movable integrated transformer substation accident oil tank oil-containing wastewater treatment device which is used for treating the oil-containing wastewater in an accidentoil tank. A drainage treatment device includes: a shell, internally provided with an oil-water separation bin, a liquid level adjustment bin, a first filtering chamber and a second filtering chamber;sloping plate packing, disposed at the upper part of the oil-water separation bin; an oil storage tank, disposed in the oil-water separation bin and located above the sloping plate packing. Due to integrated design, the device can be carried by a vehicle, so that field hoisting is avoided, and the device can be manufactured out of field and regulated and operated directly on field. The device isshort in treatment time, is free of influence on normal operation of the transformer substation, can adapt the compact arrangement and stressed field occupation of the transformer substation. The device is simple in structure, allows automatic oil-water separation, is low in manual management load in operation, is convenient to maintain and can work well just by removing the waste oil at certain frequency, and is low in operation cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment. More specifically, the present invention relates to a mobile integrated substation accident oil pool oily wastewater treatment device. Background technique [0002] The oily wastewater in the accident oil pool of the substation is the oily wastewater formed when the rainwater enters the accident oil pool when it rains, causing oil pollution to enter the pipe network. The sewage generated by this project has the characteristics of short timeliness, fast speed, and large pollution , especially in the case of heavy rain, a large amount of oil pollution enters the pipe network, and the pollution is more serious; in addition, it is worth noting that due to the existence of oil, COD will exceed the standard. Conventional accident oil pools are simple in structure, and are discharged before the oil-water separation is completed, which is likely to cause waste oil leakage, and a large...

[0002] The oily wastewater in the accident oil pool of the substation is the oily wastewater formed when the rainwater enters the accident oil pool when it rains, causing oil pollution to enter the pipe network. The sewage generated by this project has the characteristics of short timeliness, fast speed, and large pollution , especially in the case of heavy rain, a large amount of oil pollution enters the pipe network, and the pollution is more serious; in addition, it is worth noting that due to the existence of oil, COD will exceed the standard

The structure of the conventional accident oil pool is simple, and it is discharged before the oil-water separation is completed, which is easy to cause the leakage of waste oil, and a large amount of water is not conducive to the rapid collection of waste oil

At present, environmental protection requirements are becoming more and more stringent, but the use of complex water treatment processes is limited by site conditions, and the cost is high and maintenance is difficult
