Embodiment 1

[0158] Nickel-tin salt coloring sealing hole recovery coloring agent and reclaimed water utilization method, including: reverse series water-saving operation, nickel-tin wastewater interception operation, nickel-tin wastewater treatment operation, nickel phosphate recovery operation and N-P compound fertilizer recovery operation;

[0159] (1) The reverse series water-saving operation includes: open valve 14, feed tap water from the tap water inlet to the 18# flowing water washing tank, enter the 17# flowing water washing tank through the valve 15, and enter the 15# flowing water washing tank through the valve 16 , enter the 14# flowing water washing tank through valve 17, and enter the colored and sealed nickel-tin wastewater collection tank through valve 1 and pump 1; the reverse series water-saving operation is responsible for collecting the colored and sealed nickel-tin wastewater collection tank; greatly reducing the nickel content The amount of tin wastewater collected can...

Embodiment 2

[0197] Embodiment 2 (the nickel-tin salt coloring liquid working ability detection that reclaims production)

[0198] according to image 3 , continuous production of colored aluminum, 13# nickel-tin salt coloring tank is continuously added the coloring solution recovered and produced by the present invention according to the control index of formula (1); take the coloring solution pH = 1.0, temperature 25 ° C, stannous sulfate 5-10g / L (Other ingredients are calculated by (12) formula); It is 15 microns to get oxide film thickness, and coloring time is 10 minutes, and the result is as shown in table 3 below:

Abstract

The invention relates to a nickel tin salt coloring, hole-sealing and recovering hole sealer and a method of reclaimed water utilization and online configuration. The utilization method comprises thefollowing steps: reverse serial water-saving operation, nickel tin wastewater intercepting operation, nickel tin wastewater processing operation, nickel phosphate recovering operation and N-P compoundfertilizer recovering operation. The online configuration comprises a nickel tin wastewater generating system, a nickel tin wastewater collecting system, a nickel tin separating system, a nickel phosphate recovering system and a N-P compound fertilizer recovering system. By means of online configuration, water for coloring and cleaning a sealed hole is intercepted and collected by means of an online classifying recovering method to recover a nickel tin solid mixture which is converted into a nickel tin salt coloring agent. Reclaimed water which is treated is recycled and is converted into theN-P compound liquid fertilizer, so that pollution of the nickel tin wastewater to a wastewater treatment center is blocked, discharge of industrial hazardous wastes is reduced, and recycling cyclic utilization of toxic wastes is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum processing, in particular to a nickel-tin salt coloring sealing hole recovery coloring agent and a method for utilizing reclaimed water and on-line configuration. Background technique [0002] Aluminum alloy has the advantages of excellent processing performance, good corrosion resistance, beautiful surface, high recovery rate, etc., and has been widely used in construction, transportation, machinery, electric power and other industries. In recent years, the trend of aluminum replacing copper, aluminum replacing wood, aluminum replacing steel, and expanding the application range of aluminum has become more obvious. The aluminum processing industry is not only a traditional industry, but also a sunrise industry full of vitality. However, under the new normal of the economy, the common problems of high energy consumption, large amount of pollutant discharge and low resource recycling rate in the a...
