Embodiment 1

[0019] A kind of compound chemical nickel removal agent, by ferrous sulfate, ferric chloride, Al(NH 3 ) 3 , aluminum chloride, NaClO 3 , sulfonic acid, additives and water are polymerized in proportion.

[0020] Its mass ratio is 0.35:0.25:0.10:0.05:0.05:0.05:0.08:0.07.

[0021] Take a 1L glass beaker, add 70ML water, turn on the mixer, and slowly add FeSO into the beaker 4 .7H 2 O 350G, after ten minutes slowly add solid FeCl to the beaker 3 250G, at this time the beaker starts to release heat, continue to add AlCl to the beaker 3 50G, continue to stir when the temperature reaches about 40°C, add 20ML of dissolved sulfonic acid, stir for 15 minutes, continue to add dissolved Al(NH 3 ) 3 100ML, add NaClO after 5 minutes 3 50G, when the temperature continues to rise to about 80°C, add 80G of additives, continue to stir and react for 1 hour, and after aging for 24 hours, a composite chemical nickel remover is obtained.

[0022] Utilize above-mentioned compound chemi...

Embodiment 2

[0027] Identical with the component of embodiment 1 and operating condition, difference is: this a kind of composite chemical nickel remover, this composite chemical nickel remover is made of ferrous sulfate, ferric chloride, Al(NH 3 ) 3 , aluminum chloride, NaClO 3 , sulfonic acid, additives, and water are polymerized in proportion.

[0028] Its mass ratio is 0.30:0.30:0.08:0.07:0.05:0.05:0.08:0.07.

[0029] Take a 1L glass beaker, add 70ML water, turn on the mixer, and slowly add solid FeCl to the beaker 3 300G, after ten minutes slowly add FeSO into the beaker 4 .7H 2 O 300G, at this time the beaker starts to release heat, continue to add AlCl to the beaker 3 70G, continue to stir when the temperature reaches about 40°C, add 20ML of dissolved sulfonic acid, stir for 15 minutes, continue to add dissolved Al(NH 3 ) 3 80ML, add NaClO after 5 minutes 3 50G, when the temperature continues to rise to about 80°C, add 80G of additives, continue to stir and react for 1 ho...

Abstract

The invention provides a composite chemical nickel remover, which is obtained by a polymerization reaction of ingredients including ferrous sulphate, iron chloride, Al(NH3)3, aluminium chloride, NaClO3, xanthogenate, an auxiliary agent and water in proportion. Weight ratio of ferrous sulphate to iron chloride to Al(NH3)3 to aluminium chloride to NaClO3 to xanthogenate to the auxiliary agent to water is 0.30-0.35:0.25-0.30:0.08-0.10:0.05-0.07:0.05:0.05:0.08:0.07. The invention also provides a method for removing chemical nickel and chemical phosphorus in industrial wastewater. The method comprises the following steps: adding the composite chemical nickel remover into industrial wastewater, adjusting pH value to 12-14, stirring, removing ammonia nitrogen, and filtering or filter-pressing. By the method, removal rate of chemical nickel in wastewater can reach 85.50-99.99%, and removal rate of chemical phosphorus can reach 80.12-99.00%. The product is simple to operate and convenient to use, will not cause secondary pollution to the environment, and has a good effect of removing chemical nickel and chemical phosphorus.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a chemical nickel remover, in particular to a composite chemical nickel remover and its application. Background technique [0002] Water is the most important resource on the earth, and it is also the most abundant and widely distributed compound in nature, with a total amount of about 1.4*10 19 m 3 However, the vast majority is brackish seawater, and the fresh water available for development and utilization only accounts for 0.3% of the total water volume. Therefore, fresh water is an extremely limited precious resource. With the continuous acceleration of the pace of human industrialization and the gradual improvement of people's living standards, the consumption of fresh water is increasing day by day. my country's water resources account for about 1 / 4 of the world's average per capita level. With my country's rapid development in the past 30 years, the demand for industrial wa...
