Fluorine-bearing coating wastewater treatment system

Abstract

The invention provides a fluorine-bearing coating wastewater treatment system, comprising a wastewater tank, a crushing tank, a neutralizing tank, a reaction tank, a filter tank, a heating tank, a filtering device, a monitoring tank, a condensing device and a discharging tank along a flowing direction of wastewater; a filter plate is disposed in the wastewater tank, a screw extruder is arranged in the crushing tank, and the reaction tank can receive chemicals for reaction according to the determined chemical components in the coating wastewater; a plurality of filter membranes are arranged in the filter tank, and the monitoring tank can detect and further remove fluorine ion residue in wastewater; finally, the coating wastewater is heated through a sensitive heating coil, steam is filtered, and the wastewater is condensed and discharged to the discharge tank; hard and soft impurity particles in the fluorine-bearing coating wastewater can be effectively removed, harmful matters in the fluorine-bearing wastewater are removed specifically by chemical processes, complex chemical components in the fluorine-bearing coating wastewater can be classed and recycled, and further reuse is facilitated.

Description

technical field [0001] The invention belongs to the field of recovery devices, and in particular relates to a fluorine-containing paint wastewater treatment system. Background technique [0002] Fluorine-containing coatings have excellent chemical stability, weather resistance, corrosion resistance and oxidation resistance, and are widely used in new technology fields such as aviation, ocean development, energy, electronics and chemicals. However, a large amount of wastewater will be generated during the production and use of fluorine-containing coatings, and the chemical composition of the wastewater is complex, and direct discharge will cause great harm to the environment. Therefore, the recycling and treatment of wastewater has become a research hotspot, and the wastewater treatment system is to solve this problem. key. Contents of the invention [0003] In view of this, the present invention aims to propose a fluorine-containing paint wastewater treatment system to so...
