Problems solved by technology
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 complicated, time-consuming, and the separation efficiency is too low, and its purification rate cannot meet the relevant national standards, making the cost too high

Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention will be further described:
[0019] As shown in the accompanying drawings, the present invention improves the overall structure on the basis of the traditional separator, especially optimizes the structure of the filter medium layer. For different oil-water separations, different medium filtration is required, and its filtration speed and The purification rate is one aspect, and the full utilization of the filter medium layer also needs to be considered. The structure of the filter medium layer of the present invention is different from the square and flat pattern of the existing filter medium. The surface that first contacts with oil and water is set to be non-planar, which can be a downwardly concave arc surface or an upwardly convex arc surface. When controlling the filtration rate of the filter medium layer, the oil and water are evenly distributed on the surface of the filter medium layer, withou...

The invention provides a central-feeding type biconvex dual-purpose separator for sewage treatment. The central-feeding type biconvex dual-purpose 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 convex central part; the lower end surface of the filtering medium layer is of a structure with an upwardly concave central part; 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; the elastic pressing plate and the elastic supporting plate are both movably arranged; and a separator plate is arranged in the middle of the filtering medium layer to totally isolate the filtering medium layer into two parts. 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 mid-entry double-convex dual-purpose sewage treatment separator. 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 cost t...
