Problems solved by technology

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. , and more and more have entered the daily life of ordinary people, and for different fields and different industries, the types of sewage produced are different, so their water treatment processes and methods are also different, and for the current cold water In the wastewater treatment process of hot-rolling waste emulsion, most of the treatment processes have poor treatment effects, and the process is complicated. The process consumes more manpower and material resources and the treatment effect is not ideal, so the treatment cost is relatively high. high

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work fall within the protection scope of the present invention:

[0024] Since this process is aimed at treating the waste emulsion wastewater from cold rolling and hot rolling, and because this kind of waste emulsion is difficult to demulsify wastewater, in order to ensure that the system can be treated normally and stably and the water quality meets the standard, this treatment system adopts graded breaking A comprehensive treatment process combining milk and chemical physical demulsification.

Abstract

The invention discloses a treating system for cold-rolled heat-rolled waste emulsion. The treating system comprises the following steps: adding an alkaline additive into a reaction tank containing the cold-rolled heat-rolled waste emulsion, performing chemical demulsification process and regulating PH value; putting the solid residue in the reaction tank into a sludge tank, adding coagulant or flocculating agent into the sludge tank, fully reacting and performing filter-pressing treatment; conveying the primarily separated wastewater in the reaction tank into a membrane tube concentrating device and performing physical separation, thereby realizing a physical demulsification process; conveying and returning a concentrated solution separated by the membrane tube concentrating device to a waste emulsion collecting tank and then conveying the waste emulsion in the waste emulsion collecting tank to the reaction tank and circularly treating; conveying the treatment water separated by the membrane tube concentrating device into a PH regulating tank for regulating the PH value to be neutral; treating the treated neutral water according to an anaerobic aerobic technique and a coagulation sedimentation technique, thereby completing the treatment process.
