Center-feeding-type multilayer circulating wastewater treatment separator

Abstract

The invention provides a center-feeding-type multilayer circulating wastewater treatment separator, which includes an internally hollowed shell body. A water inlet and a water outlet are disposed on the shell body. A filter medium layer is disposed in the middle of the shell body. The middle part of the upper end surface of the filter medium layer is convex upwardly. The middle part of the lower end surface of the filter medium layer is concaved upwardly towards the interior of the filter medium layer. An elastic pressing board is arranged on the upper end surface of the filter medium layer, while the lower end surface is provided with an elastic jacking board. A first support rod is connected to the middle of the elastic pressing board. A plurality of first push-and-pull rods are connected to periphery of the elastic pressing board. The forces of the first support rod and the first push-and-pull rods on the elastic pressing board are in the same or opposite direction. A vertical separation board is arranged in the middle of the filter medium layer so as to separate the filter medium layer into two parts completely. The separator has simple structure and is high in processing load on the basis of small total size, is greatly increased in processing speed and purifying rate, and is suitable for oil and water separation in different types due to the character of varying structure.

Description

technical field [0001] The invention relates to the field of liquid separation devices, in particular to a mid-entry multi-layer circulating 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 too ...
