Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Figure 1, figure 2 , image 3 , Figure 4 and Figure 5 Shown, the oilfield sewage swirl auxiliary chemical treatment method of the present invention comprises the following processing steps:

[0017] (a) The sewage enters the three-phase separator 1 through the water pump. When the sewage passes through the three-phase separator to the water inlet pipe 1-1, the water flow rotates, and the rotating sewage falls along the solid-liquid cyclone separator 1-2. The separation of liquid and solid particles is realized during this falling process, and the solid particles settle into the solid storage chamber 1-4 at the bottom of the three-phase separator 1, and are discharged from the mud discharge outlet 1-7 arranged at the lower part of the solid storage chamber 1-4 , the liquid part in the sewage rises to the top of the coarse-grained packing chamber 1-5 along t...

Abstract

The invention discloses an oil filed sewage swirl auxiliary chemical disposal method, which sequentially comprises the disposal working procedures such as (a) three-phase separator, (b) liquid-liquid separator, (c) folium air pressure filter machine and (d) micro-hole filter machine, etc. The utility model is not only suitable for the disposal requirements of decentralization, no-ration, no-timing sewage discharging, but also meets the requirements of large-scale sewage disposal of continuous discharging, implements the enclosing, randomization and mobilization of the sewage disposal, and saves the energy resource; the invention has low strength intensity, strong adaptability and stable and reliable disposal effect, does not produce the secondary pollution, and can be widely applied to the sewage disposal of each oil well operation of the oil filed and other industries.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a cyclone-assisted chemical treatment method for oil field sewage. Background technique [0002] Compared with other industrial wastewater, oilfield sewage contains different solids, insoluble liquids, and soluble organic and inorganic pollutants, such as sediment, slag, oil slick, surfactants, various chemical raw materials for industrial and mining production, Inorganic salts and bacteria etc. The discharge of these pollutants into the natural environment not only pollutes the surface water system and causes environmental deterioration, but also brings many hazards to the industrial and agricultural production and people's lives around the watershed. In order to provide people with a good living environment, sewage must be treated reasonably before discharge to reduce pollutants to an acceptable level for the environment. At present, various water treatment technologies and equipm...
