Embodiment Construction
[0018] Now in conjunction with accompanying drawing, invention is described in further detail. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic way, so they only show the composition related to the invention.
[0019] figure 1 It is a schematic diagram of the framework of the present invention.
[0020] as attached figure 1 As shown, the waste water from the machine tool cutting fluid flushing fluid in the factory first enters the electrochemical air flotation system. Since the water contains a large amount of suspended impurities, the colloidal impurities and suspended impurities in the water are firstly discharged through the electrochemical reaction in the electrochemical air flotation system. Flocculation, and then through the air flotation equipment, a large number of fine air bubbles are introduced or generated in the water, so that the air is attached to the suspended solid particles in the...

The invention relates to the technical field of wastewater treatment, in particular to a method for treating machine tool cutting fluid flushing fluid. The method comprises the following steps: a) feeding waste water into an electrochemical air floatation system to perform flocculation treatment, and adding coagulant and a flocculant into an electrochemical air floatation system to perform oil removing, suspended matter removing and COD removing treatment; b) enabling the waste water treated by the electrochemical air floatation system to flow into a precision filter to perform filtering; c) enabling the waste water filtered by the precision filter to flow into a super-frequency vibration UF system to perform filtering; and d) enabling the waste water filtered by the super-frequency vibration UF system to flow into a super-frequency vibration NF system to perform filtering. Flocculation treatment is subjected through the electrochemical air floatation system. Continuous filtration is conducted through the precision filter, the super-frequency vibration UF system and the super-frequency vibration NF system. The waste water of the machine tool cutting fluid flushing fluid can be treated into recyclable water.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for treating machine tool cutting fluid flushing fluid. Background technique [0002] The existing waste water from the machine tool cutting fluid flushing fluid in the factory area needs to be treated. However, the treatment method of the existing traditional technology can only treat the wastewater into the wastewater that meets the discharge standard, but cannot treat the wastewater into reusable water. Contents of the invention [0003] In order to solve the technical problems described in the background technology, the invention provides a method for processing the cutting fluid flushing fluid of machine tools, which uses an electrochemical air flotation system for flocculation treatment. Use coagulants and flocculants to remove oil, remove suspended matter, and remove COD. Continuous filtering through precision filter, ultra-frequency vibration UF ...
