Embodiment 1

[0014] Production method: take cyclohexanol hexaphosphate as raw material to make concentrated circulating water scale inhibitor water softener.

[0015] Usage: Take the above-mentioned highly concentrated circulating water scale-inhibiting soft water agent, add 10, 15, 30mg / L highly concentrated circulating water scale-inhibiting soft water according to the water quality of the circulating water replenishment water hardness ≤ 3; 3-5; ≥ 5mmol / L After mixing and dissolving, it can be used; after the circulating water is lost, add circulating water and highly concentrated circulating water antiscaling water softener according to the above ratio.

[0016] The formulation of this embodiment is mainly suitable for water quality (low hard water) with circulating water replenishment hardness lower than 3mmol / L, and the dosage is 10mg / L water.

[0017] Features: The formula of this example has low phosphorus content. It can make the circulating water operate under the conditions of te...

Embodiment 2

[0019] Production method: according to the weight ratio of 1:2, the two raw materials of cyclohexaphosphate and 2-phosphonic acid-1,2,4-tricarboxylic acid butane are mixed evenly, which is the highly concentrated circulating water resistance scale water softener.

[0020] Usage: Take the above-mentioned highly concentrated circulating water scale-inhibiting soft water agent, add 10, 15, 30mg / L highly concentrated circulating water scale-inhibiting soft water according to the water quality of the circulating water replenishment water hardness ≤ 3; 3-5; ≥ 5mmol / L After mixing and dissolving, it can be used; after the circulating water is lost, add circulating water and highly concentrated circulating water antiscaling water softener according to the above ratio.

[0021] The formulation of this embodiment is mainly suitable for water quality (medium hard water) with circulating water replenishment hardness of 3-5 mmol / L, and the dosage is 15 mg / L water.

[0022] Features: The f...

Embodiment 3

[0024] Production method: According to the weight ratio of 1:1:0.2, the three raw materials of cyclohexanol hexaphosphate, 2-phosphono-1,2,4-tricarboxylic butane and benzotriazole are mixed, namely Highly concentrated circulating water antiscaling water softener.

[0025] Usage: Take the above-mentioned highly concentrated circulating water scale-inhibiting soft water agent, add 10, 15, 30mg / L highly concentrated circulating water scale-inhibiting soft water according to the water quality of the circulating water replenishment water hardness ≤ 3; 3-5; ≥ 5mmol / L After mixing and dissolving, it can be used; after the circulating water is lost, add circulating water and highly concentrated circulating water antiscaling water softener according to the above ratio.

[0026] The formula in this example is mainly suitable for circulating water with water replenishment hardness ≥ 5mmol / L (high hard water), high pH, ​​high Cl - Water quality, the dosage is 30mg / L water.

Abstract

The invention relates to highly enriched recycle water antisludging softener, which employs cyclohexanehexol phosphoric acid ester as raw materials. The water treatment method employs the following steps that selecting the highly enriched recycle water antisludging softener, according to the hardness of replenishing water<=3, 3-5, >=5mmol / L water quality, respectively adding 10, 15, 30mg / L highly enriched recycle water antisludging softener, after being mixed and dissolved, the water can be used, when the recycle water disappears, adding the recycle water and the highly enriched recycle water antisludging softener according to the ratio above. The highly enriched recycle water antisludging softener of the invention has low content of phosphorus, which can utmost reduce discharge capacity and the recycle water can be used periodically to realize the object of zero discharge.

Description

technical field [0001] The invention relates to a water treatment agent, in particular to a high-concentration circulating water antiscaling water softener and a water treatment method for achieving zero discharge of circulating water. Background technique [0002] Since the general water quality is relatively hard, the purpose of industrial water cannot be achieved, and water treatment agents need to be added for softening treatment. The treatment method of industrial circulating cooling water in my country generally adopts the "dissolution method", that is, adding acidic substances to make the system operate at a low pH value and control the Ca in the water. 2+ , Mg 2+ Precipitation does not occur. After running for a general time, with the consumption of water, after reaching a certain concentration ratio, it must be discharged. In this way, the consumption of water is relatively large, and the requirement of zero discharge cannot be met. Contents of the invention ...
