Abstract

The invention provides an oil field sewage treatment device, comprising a separation system, a filter system and an electric control system, wherein the separation system comprises a sewage reservoir, a grid settling tank, a sewage reservoir and an oil-water separation tank communicating with one another; the filter system comprises a primary filter, a secondary filter, a ternary filter and a quaternary filter communicating with one another; the electric control system comprises a conversion controller, a high-frequency pulse power supply, an electromagnetic valve and a main control device, wherein the conversion controller, the high-frequency pulse power supply and the electromagnetic valve are all electrically connected with the main control device; the oil-water separation tank in the separation system communicates with the primary filter in the filter system, and the oil-water separation tank communicates with the sewage reservoir, the grid settling tank and the sewage reservoir.

Description

technical field [0001] The invention specifically relates to an oilfield sewage treatment device. Background technique [0002] Petroleum and petrochemical, food and other industries produce a large amount of oily sewage. The oil in these oily sewage is dispersed and emulsified in water, which is difficult to remove. The air flotation process is one of the basic processes of sewage treatment, and electrolytic air flotation is recognized as the air flotation process with the smallest diameter of bubbles and the least disturbance to the water body. The principle is to use the electrolysis process to generate tiny bubbles, and these bubbles can absorb water. oil droplets and suspended solids, so it is easy to remove oil droplets and suspended solids from water; at the same time, if the sewage contains chloride ions, strong oxidizing bactericidal substances such as hypochlorous acid, chlorine gas, and oxygen atoms can be generated through the electrolysis process. Kill bacteria...
