Description
Technical field
The present invention relates to water treatment facilities, particularly relate to circulating water treatment device.
Background technology
Industrial circulating water is used primarily in cooling water system, so being also recirculated cooling water, purpose
It it is using water wisely.At present, the big portion of industrial circulating water is open water circulation system, so
For a long time in cyclic process, because of the continuous evaporation of water, cause the calcium ions and magnesium ions in recirculated water dense
Degree raises, and water circulation pipe corrosion speed is accelerated；Also because being the circulation of open water, tire out for a long time
Micronic dust in long-pending air, surrounding produces solid particle polluter, and pipeline rust etc. solid hangs
Floating particles；Meanwhile, because being recycled for a long time, water oxygen level is caused to decline, anaerobe,
The microorganism such as iron bacteria, chlorella is grown in a large number, and water circulation system is because of the substantial amounts of taste of these microorganisms
Bear moss, lump in equipment surface；Above-mentioned all situations have all had a strong impact on water circulation system
Properly functioning, each enterprise all has to spend a lot of time, utilize various method go improve circulation
The ecological balance of water, to ensure that circulation is properly functioning.Circulating water quality improves purification
Conventional process side is as follows:
One, recirculated water has following several except algae, the processing mode of the microorganism that sterilizes, kills:
In water add sodium chlorate, 1227, isothiazolone, glutaraldehyde, dithiocyano-methane, mantoquita
Etc. various chemical agents, and point oxidation and non-oxide two big classes, it is necessary to oxidation category and non-oxide
Class two ways be used alternatingly can be only achieved well kill, inhibition, otherwise will cause algae
Quasi-microorganism or mushroom grow in a large number, affect water circulation system and run；But, above-mentioned process side
There is certain danger in formula, the about agent of some chemistry belongs to class dangerous materials inflammable, explosive.
Two, for impurity such as the solid suspended particles deposited in recirculated water, mainly there are two big classes,
One class is the cleaning that manually discharges water；Two classes are for using filter type, and general filtration processing equipment passes
System uses the filter types such as filter screen, filter element, activated carbon adsorption.But, after filtering a period of time,
Filter screen, filter element will be blocked；Activated carbon is saturated, it is necessary to taken apart by filter plant, cleaning or
Changing filter screen, filter element, activated carbon etc. and filter important document, a whole set of filter plant recovers to filter the most again
Function, if water pollution degree is more serious, replacing will be more frequent, and needs certain
Professional skill, and still need to labor cleaning after regular (6 months-1 year) discharges water.
Three, for the calcium ions and magnesium ions in recirculated water, traditional method is to add water softener, ion friendship
Change, water add the chemical agent that can neutralize calcium ions and magnesium ions, but must periodically add,
Or use the methods such as electric osmose wash rice to remove calcium ions and magnesium ions.
The most traditional circulating water treatment method, its step is numerous and diverse, needs various water quality
Purifying problem specific aim implements different process steps, and the various professional equipments needed, and needs
Various special agents, and complex treatment process, require higher to the operant skill of technical staff.
