Integrated sewage treatment pry

Abstract

The utility model discloses an integrated sewage treatment pry, and relates to the technical field of petrochemical sewage treatment equipment, in particular to an integrated sewage treatment pry, which comprises a microbubble rotational flow air floatation device, a backwash efficient filtering device and the like. The micro-bubble cyclone flotation, coalescence filtration, backwash efficient filtration and other technologies are adopted for separating oil and sewage, removing large-particle impurities and organic pollutants and reducing the COD emission value. According to the invention, oily sewage is quite convenient to separate and collect, organic pollutants can be effectively removed, the problems of environmental pollution and the like caused by oily sewage and organic pollutants contained in the oily sewage in the past are solved, the oil-water treatment efficiency is high, the removal of the organic pollutants is remarkable, the use and the installation are convenient, the labor intensity is reduced, the economic cost is saved, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of petrochemical sewage treatment equipment, in particular to a device for separating oily sewage and reducing COD value. Background technique [0002] In the process of oil exploration, oil refining and petrochemical industry, a large amount of oily sewage will be produced. In addition to oil, sewage, sludge and other components, the sewage also contains a variety of organic pollutants. [0003] In addition to separating oil, water, and sludge, the treatment of these sewage must also remove various organic pollutants. If the organic pollutants are not treated properly, the COD value of the discharge will exceed the standard, and these organic pollutants will be discharged along with the , deposited in rivers, lakes or soil, seriously polluting the environment, endangering human body and other animals and plants, and even destroying the ecosystem. At present, when dealing with oily sewage containing organic...

AI Technical Summary

Problems solved by technology

[0003] In addition to separating oil, water, and sludge, the treatment of these sewage must also remove various organic pollutants. If the organic pollutants are not treated properly, the COD value of the discharge will exceed the standard, and these organic pollutants will be discharged along with the , deposited in rivers, lakes or soil, seriously pollutes the environment, endangers human body and other animals and plants, and even destroys the ecosystem

At present, when dealing with oily sewage containing organic pollutants, the principles and methods adopted to separate oil, sludge, and remove organic pollutants require repeated treatment many times. The treatment efficiency is low, the effect is poor, and the discharge or use standards cannot be met.
