Abstract

The invention discloses an integral treatment device and method for metal processing waste liquid. The treatment device comprises a waste liquid collection pool and a pretreatment tank, the waste liquid collection pool is located on the right side of the pretreatment tank, and the invention relates to the technical field of metal processing waste liquid treatment. According to the integral treatment device and method for metal processing waste liquid, a first circulating pipe is fixedly connected in a first circulating tank through fixed blocks, a flat nano-membrane is fixedly connected in thefirst circulating pipe, a second circulating pipe is fixedly connected in a second circulating tank, an RO anti-pollution membrane is fixedly connected in the second circulating pipe, and a membraneion purification assembly is fixedly connected in a third circulating tank. The combined action of the flat nano-membrane, the RO anti-pollution membrane and the membrane ion purification assembly isutilized to realize separation and collection of 95% o more of floating oil in the waste liquid, also 80-90% of clean liquid can be further separated from the waste liquid for recycling, thus reachingthe purpose of substantial reduction of the waste liquid discharge amount.

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...
