An integrated device and method for treating metal processing waste liquid

Abstract

The invention discloses an integrated device and method for treating waste liquid in metal processing, including a waste liquid collection tank and a pre-treatment tank, and the waste liquid collection tank is located on the right side of the pre-treatment tank. The invention relates to the treatment of waste liquid in metal processing technology field. The overall device and method for treating metal processing waste liquid are fixedly connected with a first circulation pipe through a fixed block through the inside of the first circulation tank, the inside of the first circulation pipe is fixedly connected with a flat nano-membrane, and the inside of the second circulation tank The second circulation pipe is fixedly connected, the inside of the second circulation pipe is fixedly connected with RO anti-fouling membrane, and the inside of the third circulation tank is fixedly connected with membrane ion purification components, using flat nano-membrane, RO anti-fouling membrane and membrane ion purification The joint action of the components can separate and collect more than 95% of the floating oil in the waste liquid, and can further separate the waste liquid into 80%-90% of the clean liquid, which can be recycled and reused, thereby achieving a significant reduction in waste purpose of liquid discharge.

Description

technical field [0001] The invention relates to the technical field of metal processing waste liquid treatment, in particular to an integrated device and method for processing metal processing waste liquid. Background technique [0002] Waste liquid treatment includes waste liquid incineration, organic waste liquid treatment or organic industrial waste liquid treatment, also known as high-concentration organic wastewater treatment. The treatment methods include physical treatment, chemical treatment and biological treatment. Chemical treatment generally also Combined with physical processes, it is also called physical and chemical treatment. Physical treatment refers to the use of physical or mechanical separation to treat waste liquid. The commonly used methods are: filtration, sedimentation, flotation, oil separation and centrifugal separation. Chemical treatment It is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater...
