"YF unified gas tank device", and other works, although flotation
device is basically the same principle, but there are major changes
in the structure, it has the following advantages:
- Integrated Device
Usually flotation systems, they are separate flotation tank, dosing
equipment, dissolved gas cylinders, dissolved air pumps, air
compressors, water pumps, thus adding to install a long time,
inconvenience management, large area. YF gas tank to separate these devices combined organic whole, is
generally adjusted sewage PH value, just plug out of the water
spout, etc., can be immediately put to use, and does not require a
- Automatic operation of
YF flotation Once commissioning is completed, normally without
expert management, operation can be achieved Automatic management
of unmanned state.
1, electroplating wastewater heavy metals such as chromium, zinc,
copper, nickel, lead and total content of 50PPM or less, and
removal can be found in about 70%, about 90% of suspended solids
2, printing and dyeing wastewater color removal rate of about 90%,
COD removal efficiency of about 60-70%, BOD removal rate of about
3, slaughter and food tannery wastewater COD removal efficiency of
about 70%, about 90% of suspended solids removal.
4, oil refinery wastewater, can be reduced to 10 mg / liter or
less, clarified wastewater can reach the degree.
5, the chemical waste water and paint pigment, COD removal
efficiency of 74%, about 93% of color removal.
6, White Water fiber recovery rate can reach about 95%, COD removal
efficiency of about 86.7%, with fresh water reuse.
7, large pool shower water turbidity can be stabilized at below 10
degrees, the water of bacteria have a greater rate of decline.
8, drinking water and industrial turbidity can be purified to below
5 degrees, while the chroma oxygen consumption with good results.
After flotation device works is that under certain conditions, a
large amount of air dissolved in water to form a dissolved gas and
water, as the working medium, by releasing the device sudden
decompression, quick release, a large amount of fine bubbles
adhered to the through coagulation reaction the wastewater "alum",
the so floc floating to remove contaminants in the water quickly,
achieve the purpose of water purification.
YF flotation divided into four parts:
(A) dosing flocculating section, (ii) an aqueous reflux gas release
portion, (c) flotation section, and (iv) the electrical control.
(A) dosing flocculating part:
Sewage from the sewage pump sewage tank pumped to the vortex
reactor. Commonly used in sewage pump before dosing. This allows the liquid through the sewage and wastewater pump
impeller rotation and fully mixed. Liquid is supplied from Dosing system. Increase over drug sewage into the vortex reactor effluent fully
polybrene. (Such as the user needs to be changed to other forms of polybrene)
(B) an aqueous reflux gas release portion:
Flotation effect is good or bad, depending on the gas and releasing
an aqueous reflux effect. The flotation using energy-efficient equipment and release of
dissolved air. And the compressed air compressor after processing by pressurized
pump back water tank sufficiently mixed and dissolved in a solvent
to form water containing dissolved gas.Dissolved gas cylinders working pressure is generally 2-3.5kg /
(C) flotation part:
By dosing coagulation of sewage into the flotation tank, the tank
dissolved in water containing dissolved gas in the lower part of
the mouth out of the water by the sudden release of dissolved air
pressure, air dissolved in the water by the sudden release of
pressure and a lot of micro bubble. Microbubbles encountered during ascent sewage has polybrene
suspension, microbubbles attached to the suspension to make it go
up very quickly, so that the sewage disposed of all the suspended
solids floating on top. And then through the upper part of the flotation foam blowing
machine to scrape them discharged sludge tank and the bottom of the
pool water through the discharge process.
