Integrated wastewater lifting oil removal and oil removal tank

Technical Field

The utility model belongs to oily waste water treatment field relates to an integration waste water promotes oil removal deoiling pond.

Background

The transformer substation of the steel plant is generally provided with an accident oil pool, and after the oily wastewater is subjected to simple oil-water separation, because the density of oil is smaller than that of water, the oil is remained in the accident oil pool, and the wastewater is automatically discharged. Only when the accident oil pool is filled with oil under the condition of an accident, workers can pump the oil away through the oil pump. However, under the non-accident condition of the transformer substation, the oil in the accident oil pool is not usually treated, due to the daily maintenance and overhaul of the transformer, an oil layer often still exists in the accident oil pool, the liquid level is usually at different heights along with the infiltration of underground water and the difference of rainfall, and generally, a worker often takes the part of oily wastewater as general wastewater to be pumped away and discharged during the maintenance, so that the environment is polluted; or the operator uses a scraper to scrape off the floating oil, which consumes a great deal of manpower and time and simultaneously causes incomplete separation.

In addition, because the outside of the steel mill is under many conditions, in order to change the lifted wastewater from gravity flow to pressure flow, a collecting tank is usually added near the accident oil tank, and then the gravity flow wastewater is changed into pressure flow through a water suction pump, but the method excavates twice, prolongs the pipeline, and greatly increases the cost and investment.

Therefore, the new oil removal and oil removal tank is used for solving the problems of treatment of oily wastewater in the non-accident condition of a transformer substation and how to convert gravity flow wastewater into pressure flow wastewater at low cost.
