Description
Technical field
The present invention relates to Sewage treatment fields, and in particular to formation foil production line Sewage treatment utilizes method.
Background technique
On formation foil production line, workshop needs to be prepared with pure water equipment with water, tap water after pure water equipment most
Two kinds of water are come out eventually, and concentrated water and pure water, concentrated water return to former pond and reused, and pure water is used for workshop producing line.
The waste water that workshop generates is divided into: 1. producing line tank liquor, and the 10% of the total wastewater flow rate of Zhan；2. the not phosphorous rinsing that producing line generates
Water (water sample that total phosphorus value is less than 3mg/L), the 40% of the total wastewater flow rate of Zhan；3. (total phosphorus value is greater than the phosphorous rinse water that producing line generates
The water sample of 100mg/L), the 50% of the total wastewater flow rate of Zhan.These three water constitute plant effluent, are immediately discharged to Sewage Disposal progress
Contaminant degradation processing handles rear discharge up to standard, and during this, there are the height of cost of sewage disposal, with the height of water cost, row
The height of cost is put, and relevant departments, local government can collect charges for disposing pollutants according to the amount of discharge water sample.
Formation foil production line cooling water recirculation system: to keep each groove body water temperature stability of producing line, a set of circulation used is cold
But system.Medium temperature that process is as follows: high-temperature pool (70 DEG C ~ 72 DEG C) -- reducing water temperature (can evaporate water loss) by cooling tower --
Pond (38 DEG C ~ 40 DEG C) -- the water of middle heated pool is transported to workshop producing line as cooling water as cooling water, passes through heat exchanger
For each groove body water temperature degradation temperature -- cooler-water temperature rises back to high-temperature pool.Formation foil production line cooling water cyclic system
System, the water for evaporating consumption is about 34 tons/(day * line), water consumption is high, is that the consumption of this part is supplemented using tap water now
Amount.
Summary of the invention
The purpose of the present invention is to provide a kind of formation foil production line Sewage treatments to utilize method, solves current producing line and uses
Pure water amount is too big, and cost is too high；The wastewater flow rate that producing line generates is also big, big to the difficulty of rear end sewage plant processing waste water, is processed into
This height；Water discharge quantity is more, pays the problem more than charges for disposing pollutants.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of formation foil production line Sewage treatment utilizes method, comprising the following steps:
Step 1, the phosphorous rinse water that formation foil production line is generated, tank liquor waste water and the not phosphorous rinse water of generation are single respectively
Solely collect；
Step 2, the water quality of phosphorous rinse water according to needed for formation foil production line, and the water quality of not phosphorous rinse water, selection
Reclaimer, the reclaimer includes the cartridge filter of aperture≤5 μm, aperture≤1nm reverse osmosis membrane, except in processing water
Inorganic ions, bacterium, virus, organic matter etc.；
Step 3, reclaimer handle the phosphorous rinse water and not phosphorous rinse water that are collected into, and by purification and divide
From purified water and dope is obtained, obtained purified water is sent formation foil production line back to and is reused, and obtained dope is sent to sewage treatment
It is discharged after being handled to discharge mark at station.
Three kinds of waste water on production line are separately recovered, and by handling respectively, to be used, reduce waste water
Discharge amount, while having saved industrial water.
Further technical solution is the step three, and reclaimer is to the phosphorous rinse water that is collected into and not phosphorous
Before rinse water is handled, phosphorous rinse water is subjected to moment ozone treatment, and kept for anaerobic environment 48 hours or more, then pass through
Fenton process processing.Phosphorous rinse water needs the hypophosphorous acid to this Duan Shuizhong because wherein containing significant component of hypophosphorous acid root
Radical ion is first converted to positive phosphorus acid ion, it can be achieved that being converted to orthophosphoric acid up to 90% or more to hypophosphorous acid.
Further technical solution is, the Sewage Disposal treated water, reaches after water quality requirement by aperture≤1
μm microfiltration equipment fine sediment is filtered off, lead to formation foil production line cooling water recirculation system, the water quality requirement: 25 DEG C
At a temperature of, electric conductivity value < 800us/cm；PH value < 9；Total phosphorus≤0.7mg/L；Ammonia nitrogen≤10 mg/L；The mg/L of SS≤2, avoids pair
The corrosive pipeline of formation foil production line cooling water recirculation system.
Further technical solution is that two position linkage is equipped in formation foil production line cooling water recirculation system automatically
Control system, to achieve the purpose that automatic water supplement.The design requirement of automatic water supplement, when formation foil production line cooling water cyclic system
