Petroleum coking wastewater treatment device

Abstract

The invention provides a petroleum coking wastewater treatment device, and relates to the field of petroleum coking wastewater treatment. The petroleum coking wastewater treatment device comprises a water storage tank, an oil-water separation device, an ammonia nitrogen reaction tank and a purification tank, wherein the water storage tank is fixedly mounted on the right side of a base, and a cooling layer is arranged on the inner wall of the water storage tank. According to the petroleum coking wastewater treatment device, through the oil-water separation device arranged on the base, wastewater is heated by the heating box, oil is activated to float upwards to be layered with the wastewater, then deoiled wastewater is discharged through a wastewater discharge port by virtue of an isolationplate arranged on the left side, and dirty oil is left in the water-oil separation cavity and is extracted by virtue of an oil skimmer; the problem that an existing petroleum wastewater device is nothigh in dirty oil separation efficiency is effectively solved, the ammonia nitrogen neutralization tank and the air pump are arranged in the ammonia nitrogen neutralization tank, a proper alkaline solution is added, ammonia nitrogen elements can generate ammonia gas more quickly when making contact with air, and the ammonia nitrogen removal efficiency is improved efficiently, conveniently and rapidly.

Description

technical field [0001] The invention relates to the field of petroleum coking wastewater treatment, in particular to a petroleum coking wastewater treatment device. Background technique [0002] Petroleum coking is one of the petroleum refining processes. It is a process in which residual oil undergoes deep cracking reaction under the conditions of heating and long reaction time, and is converted into gas, gasoline, diesel oil, heavy distillate oil and petroleum coke. [0003] The wastewater in the petroleum coking process mainly comes from the wastewater containing various inorganic substances produced in the refining process, which contains a large amount of pollutants such as oil, ammonia, salt and phenol. The composition is very complex, the discharge volume is large, and the treatment is difficult. , not only wasting resources but also polluting the environment, causing great harm to water bodies. With the increasing shortage of water resources and the strengthening of...
