High efficient Lamella plate clarifier for power plant and boiler
waste water treatment
The lamella clarifier also called inclined plate sediment tank,
It is kind of high efficient combined type settling tank; set many
dense inclined tube packing in sediment area, to make the suspended
impurity in water sediment, water rise flow along inclined tube,
the separated sludge down to the tank bottom along the inclined
tube by gravity, then discharge it in concentration. Such tank can
improve sediment efficiency 50~60%, it can improve treatment
capacity 3~5 times in the same area. It can design different flow
rate inclined plate sediment device according to raw waste water
test report, it need dose flocculant usually.
Inclined plate sediment water purifier is format by install 60° dip
angle inclined tube above the sludge suspended layer, to make the
suspended solids or floc alum flower by dosing flocculant
accumulate into thin sludge later in inclined tube downside
superficial area, slide back to sludge suspended layer rely on
gravity, then settling in sludge collecting hopper, discharge into
sludge tank by sludge pipe for separate treatment or comprehensive
utilization. The supernatant fluid gradually rise to water
collecting pipe discharge or reuse.
1), simple structure,without wearing parts,wear well,decrease
2), steady operation,easy operation
3), small power,save energy
4), small occupy area, low investment, high efficient
5), short retention time, high sediment efficiency, no sludge
3. Application scope
1. electroplate effluent contain many kinds of metal ion,
cr,cu,Fe,Zn ,Ni etc remove rate all above 90%, after treatment, all
can reach discharge standard.
2. coal mine,mineral processing waste water all can make the
turbidity from 500-1500 mg/L reduce to 5 mg/L.
3. printing and dyeing,bleach and dye etc effluent chroma removing
rate reach 70~90%,COD remove rate 50-70%.
4. Tannery ,food etc industrial sewage COD remove rate 50~80%,
impurity solids remove rate above 90%.
5. chemical waste water COD remove rate 60~70%, chroma removal rate
60~90%, suspended solids reach discharge standard.
