Embodiment 1

[0141] Nickel-tin salt coloring recovery coloring agent and reclaimed water utilization method, including: nickel-tin wastewater treatment operation, nickel phosphate recovery operation and N-P compound fertilizer recovery operation;

[0142] (1) described nickel-tin waste water treatment operation comprises: open valve 1, open pump 1, the nickel-tin waste water that the tank bottom water outlet of 14# flowing washing tank is discharged is pumped into the colored sealing nickel-tin waste water collecting tank standby; Open valve 2 and valve 3, close valve 4, turn on pump 2, pump nickel-tin wastewater into the nickel-tin solid recovery tank as a reaction solution; open valve 4 and valve 6, turn on pump 3 and 1# electric stirring, and circulate the reaction solution; slowly open Valve 5, suck the liquid ammonia in the liquid ammonia tank into the pump 3, and use the high-speed rotation of the pump 3 to fully mix the reaction solution; while adding liquid ammonia, check the pH val...

Embodiment 2

[0174] Embodiment 2 (the nickel-tin salt coloring liquid working ability detection that reclaims production)

[0175] according to figure 2 , 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 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 material processing, in particular to a nickel-tin salt colored recovery colorant, a method for utilizing reclaimed water and a system thereof. 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 scope of aluminum application has become more obvious. The aluminum processing industry is not only a traditional industry, but also a sunrise industry full of vitality. According to statistics, the per capita annual consumption of aluminum alloy in developed countries in Europe and the United States is more than 32kg, while the per capita consumption in my...
