Embodiment 1

[0041] The high-gravity sewage treatment device of the present invention includes a storage tank 1 for storing electric desalination sewage or air-lifted water sewage, a lye tank 2 for storing demulsifiers, and a high-gravity machine 3; wherein a suitable one is selected The purpose of lye is to contact and exchange with electric desalination sewage to remove the impurities that need to be removed.

[0042] A filter is connected to the sewage outlet of the storage tank 1; a membrane module 6 is connected to the sewage outlet of the filter, wherein for the selection of the membrane module 6, it is preferably set to be composed of a multi-stage tubular membrane module 6, and the multi-stage tube The type membrane module 6 has a concentrated water outlet 7 and a purified water outlet 8; wherein, the purified water outlet 8 can be directly discharged to a sewage purification treatment plant for further subsequent treatment.

[0043]The supergravity machine 3 has a casing 9, on whi...

Embodiment 2

[0051] The supergravity sewage treatment process of the present invention, processing step is as follows:

[0052] (1) Perform filtration and impurity removal treatment on electro-desalted sewage at 40°C to filter out organic particles with a particle size greater than 50um;

[0053] (2) Cooling the sewage after removing impurities until its temperature is 40°C;

[0054] (3) Boost the pressure of the cooled sewage to 0.3MPa, set the temperature at 40°C, and enter the membrane module. The membrane material of the membrane module is a highly hydrophilic and super oleophobic membrane. Side concentration and enrichment, oil and water are separated;

[0055] (4) The concentrated oil and impurity concentrated water and demulsifier after membrane separation enter the fluid inlet of the supergravity machine under the rotating state, and spin into the packing area after passing through the rotating channel. In the packing area, the concentrated water and broken water The emulsion is ...

Embodiment 3

[0057] The supergravity sewage treatment process of the present invention, processing step is as follows:

[0058] (1) Filter and remove impurities from the air-lifted sewage at 50°C, and filter out organic particles with a particle size greater than 50um;

[0059] (2) Cooling the sewage after removing impurities until its temperature is 50°C;

[0060] (3) Boost the pressure of the cooled sewage to 1.0MPa, set the temperature at 50°C, and enter the membrane module. The membrane material of the membrane module is a highly hydrophilic and super oleophobic membrane. Side concentration and enrichment, oil and water are separated;

[0061] (4) The concentrated oil and impurity concentrated water and demulsifier after membrane separation enter the fluid inlet of the supergravity machine under the rotating state, and spin into the packing area after passing through the rotating channel. In the packing area, the concentrated water and broken water The emulsion is mixed with liquid a...

Abstract

The invention relates to a supergravity sewage treatment device. Firstly, a filter and a membrane component are utilized for carrying out pretreatment on electro-desalting sewage, then alkali liquor in an alkali liquor tank is mixed with the sewage treated by the filter and the membrane component, the mixture enters a supergravity machine through a fluid channel of the supergravity machine, by virtue of a unique supergravity machine structure and a rotating channel which is formed between a hollow rotating shaft and a sleeve, is communicated with a filler region and is provided with a helical channel, spinning entrance of fluid through the rotating channel after passing the hollow rotating shaft is realized, intensive mixing of the sewage in the fluid and the alkali liquor is realized under the actions of a rotation acting force, a shearing force and a spinning acting force of the fluid at the moment that the fluid enters the filler region, and sufficient degree of liquid-liquid contact is improved, so that removal of the alkali liquor on oily substances and COD in the sewage is realized.

Description

technical field [0001] The invention relates to a supergravity sewage treatment device, which belongs to the technical field of sewage treatment. Background technique [0002] Sewage is one of the common industrial wastes in modern industry. According to different sources, sewage will contain different harmful substances, such as heavy metals, organic matter, microorganisms, etc. Judging from the existing form of these harmful substances, some are water-soluble, and the other part exists in the form of oil. Generally speaking, no matter the sewage containing the above-mentioned harmful substances, or the sewage in which harmful substances exist in any form, it needs to be properly treated physically or chemically so that it can meet the requirements when it is discharged. National requirements for the discharge of such sewage. [0003] At present, the common sewage treatment methods include physical method, physical chemical method, chemical method and biological method. ...
