Preparation method of inorganic polymeric water purifier

[0017] The polyferric chloride water purifying agent was prepared according to the following parts by weight: 50 parts of pyrite slag, 15 parts of diatomaceous earth, 200 parts of sulfuric acid, 150 parts of hydrochloric acid, 10 parts of sodium chlorate, and 30 parts of nitric acid.

[0018] The preparation method of above-mentioned polymeric ferric chloride water purifying agent, comprises the following steps:

[0019] (1) Pulverize the pyrite slag and diatomite to 200 mesh and set aside.

[0020] (2) Add sulfuric acid and hydrochloric acid to the reaction kettle with a pressure of 0.3Mpa and heat to 50°C.

[0021] (3) Add the powder obtained in step (1) into the reaction kettle and stir for 2 hours.

[0022] (4) Add sodium chlorate and nitric acid into the reaction kettle, heat to 60°C, and stir for 5 hours.

[0023] (5) The solution in the reaction kettle in the step (4) is allowed to stand for cooling to obtain the polyferric chloride water purifying agent.

[0025] The polyferric chloride water purifying agent was prepared according to the following parts by weight: 100 parts of pyrite slag, 25 parts of diatomaceous earth, 350 parts of sulfuric acid, 250 parts of hydrochloric acid, 20 parts of sodium chlorate, and 50 parts of nitric acid.

[0026] The preparation method of above-mentioned polymeric ferric chloride water purifying agent, comprises the following steps:

[0027] (1) Pulverize the pyrite slag and diatomite to 300 mesh and set aside.

[0028] (2) Add sulfuric acid and hydrochloric acid to the reaction kettle with a pressure of 0.3Mpa and heat to 50°C.

[0029] (3) Add the powder obtained in step (1) into the reaction kettle and stir for 2 hours.

[0030] (4) Add sodium chlorate and nitric acid into the reaction kettle, heat to 60°C, and stir for 6 hours.

[0031] (5) The solution in the reaction kettle in the step (4) is allowed to stand for cooling to obtain the polyferric chloride water purifying agent.

[0033] The polyferric chloride water purifying agent was prepared according to the following parts by weight: 80 parts of pyrite slag, 20 parts of diatomaceous earth, 300 parts of sulfuric acid, 200 parts of hydrochloric acid, 15 parts of sodium chlorate, and 45 parts of nitric acid.

[0034] The preparation method of above-mentioned polymeric ferric chloride water purifying agent, comprises the following steps:

[0035] (1) Pulverize the pyrite slag and diatomite to 400 mesh and set aside.

[0036] (2) Add sulfuric acid and hydrochloric acid to the reaction kettle with a pressure of 0.3Mpa, and heat to 60°C.

[0037] (3) Add the powder obtained in step (1) into the reaction kettle and stir for 2 hours.

[0038] (4) Add sodium chlorate and nitric acid into the reaction kettle, heat to 60°C, and stir for 4 hours.

[0039] (5) The solution in the reaction kettle in the step (4) is allowed to stand for cooling to obtain the polyferric chloride water purifying agent.
