Petroleum wastewater treatment device

Abstract

The petroleum wastewater treatment device comprises a filter tank, a cover plate is arranged at the top of the filter tank, a second guide pipe is fixedly connected to the top of the left side of the filter tank, an ultrafiltration membrane is fixedly connected to the right position of the middle of the bottom of the filter tank, and the ultrafiltration membrane is fixedly connected with the side walls of the front end and the rear end of the filter tank. A discharging pipe is arranged at the bottom end of the right side of the filtering tank, one end of the discharging pipe penetrates through the bottom of the filtering tank, the other end of the second guide pipe is fixedly connected with a hydrolysis acidification tank, and the bottom end of the hydrolysis acidification tank is fixedly connected with a third guide pipe. According to the device, the ultrafiltration membrane is arranged, waste residues can be discharged along the discharging pipe, a heavy metal detector is arranged in the water outlet tank, and after the heavy metal detector detects that the waste residues reach the wastewater heavy metal content standard, an activated carbon plate arranged at the tail end of the water outlet pipe adsorbs microorganisms to generate impurities, and the waste residues are discharged through the water outlet pipe; if the heavy metal detector detects that the wastewater exceeds the standard, the wastewater flows back to the filter tank through the first guide pipe for circular treatment, and the device is worthy of vigorous popularization.

Description

technical field [0001] The invention relates to the field of petroleum, in particular to a petroleum wastewater treatment device. Background technique [0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons, which has a natural state of production. Petroleum is further divided into crude oil, natural gas, natural gas liquid and natural tar. However, it is customary to use "petroleum" as the definition of "crude oil". , Petroleum is a viscous, dark brown liquid, known as the "blood of industry". At present, the development of the petroleum refining industry and the national economy is very close, no matter industry, agriculture, transportation and national defense construction are inseparable Petroleum products. [0003] Petroleum fuel is a liquid fuel that is easy to use and has high energy utilization. When refining petroleum raw materials, a large amount of waste will be separated. The existing wastewater treatment equipment covers a large area, a...

Problems solved by technology

[0003] Petroleum fuel is a liquid fuel that is easy to use and has a high energy utilization rate. When refining petroleum raw materials, a large amount of waste will be separated. The existing wastewater treatment equipment occupies a large area, and some of the evaporated gas also contains Trace chemical elements have a certain impact on the air and the quality of the purified water. Some equipment uses one evaporation, which cannot be completely purified. The effect is not good, the treatment method is complicated, the treatment effect is unstable, and the quality of the effluent is low.
