Multilayer biconcave laterally-feeding oil-water separator for sewage treatment

Abstract

The invention provides a multilayer biconcave laterally-feeding oil-water separator for sewage treatment. The oil-water separator comprises a hollow shell, wherein the upper end of the shell is provided with a water inlet, the lower end of the shell is provided with a water outlet, and filtering medium layers are arranged in the central part of the shell. Each of the filtering medium layers is of a compressable, reboundable and elastic structure; the upper end surface of the filtering medium layer is of a structure with a downwardly concave central part; the water inlet is formed in the edge of the upper end of the shell; the lower end surface of the filtering medium layer is of a structure with an downwardly convex central part; distances between corresponding parts of the upper and lower end surfaces of the filtering medium layer are identical, i.e., the shapes of the upper and lower end surfaces are identical; an elastic pressing plate is arranged on the upper end surface of the filtering medium layer and an elastic supporting plate is arranged on the lower end surface of the filtering medium layer; and the elastic pressing plate and the elastic supporting plate are provided with water-passing holes and are both movably arranged. The separator is simple in structure, great in treating capacity under the condition of a small integral size, and greatly improved in treating speed and purifying rate; and the characteristic of changeability of the structure of the separator enables the separator to be adaptive to a variety of types of oil-water separation.

Description

technical field [0001] The invention relates to the field of liquid separation devices, in particular to a multi-layer double concave side entry type oil-water separator for 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 standard...
