Embodiment

[0054] Example: such as Figure 1-9 As shown, the present invention provides a technical solution for an environmentally friendly electroplating wastewater treatment device that prevents pollution. An environmentally friendly electroplating wastewater treatment device that prevents pollution includes a separation tank 1. One end of the separation tank 1 is embedded with an observation window 2, and an aeration component 3 is installed on the inside of the separation tank 1, and the aeration component 3 is used to aerate it, so that the impurities contained in the wastewater are in the bubbles. Separation and generation of flocs under the action, so as to purify them, and set up interception of flocs, so as to separate metal substances from flocs;

[0055] A collection assembly 7 is installed on the top of the separation tank 1, and the flocs floating on the water surface are collected by the collection assembly 7, which prevents the substance from re-merging into the water aft...

Abstract

The invention discloses an anti-pollution environment-friendly electroplating wastewater treatment device which is characterized in that an air pump is mounted at one end of the outer side of a separation tank, the air outlet end of the air pump is connected with the air inlet end of an air inlet pipe, one side of the air inlet pipe is connected with an air outlet pipe, and the bottom end of the air outlet pipe is mounted at the top end of an annular air pipe; one end of the air outlet pipe and the side end of the annular air pipe are provided with air outlet holes, a decelerating cylinder isplaced on the inner side of the separation tank, a decelerating net is welded to the bottom end of the decelerating cylinder, a stirring fan is welded to the side end of a transmission rod, an inclined scraping plate is welded to the side end of the transmission rod, the air outlet speed is changed through the air outlet holes, the bubble generation speed is increased, the aeration efficiency is improved, and meanwhile part of metal ions can be subjected to redox reaction, and thus the precipitate of metal compounds is generated, and the speed of flocculate is reduced through the deceleratingcylinder and the decelerating net so that metal impurities can be separated from flocculate and fall to the bottom end of the separation tank, and the wastewater treatment effect and efficiency are guaranteed.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to an environment-friendly electroplating wastewater treatment device for preventing pollution. Background technique [0002] The sources of electroplating wastewater are generally plating cleaning water, waste electroplating solution, other wastewater, and equipment cooling water. The water quality and quantity of electroplating wastewater are related to factors such as the process conditions of electroplating production, production load, operation management, and water use methods. Contains chromium, cadmium, nickel, copper, zinc, gold, silver and other heavy metal ions and cyanide, some of which are highly toxic substances that are carcinogenic, teratogenic, and mutagenic. [0003] However, when the electroplating wastewater currently on the market is aerated, the metal impurities contained in the wastewater will float to the water surface together with the flocs. When the...
