Biconvex dielectric-layer sewage treatment oil-water separator

Abstract

The invention relates to a biconvex dielectric-layer sewage treatment oil-water separator which comprises a casing, wherein the inside of the casing is hollow; a water inlet is formed in the upper end of the casing; a water outlet is formed in the lower end of the casing; a filtering medium layer is arranged in the middle in the casing. The separator is characterized in that the filtering medium layer is in an elastic structure capable of being compressed and rebounded; the upper end surface of the filtering medium layer is in a structure with the middle part raised upwards; the water inlet is arranged in the middle of the upper end of the casing and faces to the top end of the raised structure of the filtering medium layer; the lower end surface of the filtering medium layer is in a structure with the middle part sunk upwards into the filtering medium layer; all positions of the upper end surface and the lower end surface of the filtering medium layer have the consistent distance, namely, the upper end surface and the lower end surface have the consistent shape. The separator is relatively simple in the structure; the overall volume can be smaller, but the treatment capacity is large; the treatment speed and the purification rate are greatly improved; due to the feature that the separator is various in structures, the separator can adapt to different types of oil-water separation.

Description

technical field [0001] The invention relates to the field of liquid separation devices, in particular to an oil-water separator for double-convex medium layer sewage treatment. Background technique [0002] Oil-water separation is an essential process operation link in daily life and industry. It is very important for reducing environmental pollution or reusing resources, especially in the process of sewage treatment. How to effectively separate and recycle oil and water has been studied for many years in practice and theory. The existing oil-water separation devices for sewage treatment mainly use air suspension, filter medium filtration, etc., and need to go through multiple links to complete , its main disadvantage is that it can only be used in large-scale processing occasions, the device and its processing process are too complex, time-consuming, and the separation efficiency is too low, and its purification rate cannot meet the relevant national standards, making the c...
