Embodiment Construction
[0010] A method for reducing turbidity and corrosivity of circulating water, comprising the steps of:
[0011] a. Extract deep well water and perform reverse osmosis filtration on the deep well water;
[0012] b. Add appropriate amount of calcium ions and magnesium ions to the water filtered by reverse osmosis. The amount of calcium ions and magnesium ions added can be adjusted appropriately according to the actual water quality.

The invention provides a method for reducing circulating water turbidity and corrosivity, which comprises the following steps: a. pumping out deep well water, performing reverse osmosis filtration of the deep well water; b. adding a proper amount of calcium ions and magnesium ions into the water after reverse osmosis filtration. The advantages and active effects of the method are that: the problems of circulating water sludge obstruction and equipment pipeline corrosion are solved thoroughly; the heat exchange efficiency is increased; the energy is saved; the start-up rate is increase; and benefits are provided for enterprises.
Description
technical field [0001] The invention belongs to the field of water treatment, in particular to a method for reducing the turbidity and corrosion of circulating water. Background technique [0002] Because there are many impurity ions in deep well water, after it is used as circulating water to make up water, the cooling equipment tube bundles will often be blocked by sludge, and the equipment will be severely corroded. Especially when the chloride ion content in deep well water exceeds the standard seriously, the corrosion of stainless steel equipment will be more serious. The acid coolers of our company's dry suction posts are all made of stainless steel, and the requirements for circulating water quality are more prominent. Contents of the invention [0003] The object of the present invention is to provide a method for reducing the turbidity and corrosion of circulating water. [0004] The technical scheme of the present invention is as follows: [0005] A method for...
