I. Introduction:

Sedimentation is, is suspended in the sludge layer fooled installation angle of 60 degrees inclined tube formation, then raw water suspended solids, or solids formed by adding coagulants alum floc,

The surface area of ??the bottom side of the chute accumulate into a thin layer of mud, relying on gravity sludge suspension will slip layer, and then sink into the mud bucket, mud tubes into the sludge tank by a separate processing or utilization,

The supernatant was gradually increased to gradually exhaust collector pipe can be directly discharged or will be used.

Sedimentation is, is based on advection sedimentation tank to remove sediment fraction of particles in principle made ??by the increase in the pool ramps, while reducing the hydraulic radius. Increase water

Pool cross section of wet week, so the water level at the same flow rate V, can greatly reduce the Reynolds number Re, thereby reducing the flow accumulator promote precipitation, in addition, installing ramps also

Precipitated particles can shorten the distance. Reduce settling time and improve the efficiency of precipitation.

Second, characteristics:

1, simple structure, no wearing parts, durable and reduced maintenance.

2, stable, easy to operate.

3, less power and save energy.

4, small footprint, low investment, start fast and efficient.

5, packing is hexagonal honeycomb inclined tube filler materials are polypropylene, glass, steel and so on.

6, generally inclined tube inclination 60 °, according to need can be made 50 °, 55 ° and so on.

7, when the inclined tube length is one meter, the payload by 2 ~ 8m3/m2 design.

8, adaptable, able to adapt to the impact load is large in different water treatment processes.

Third, install and use:

1 When installing applications inclined tube of glue or adhesive fixing electrical bonding methods. Parallel plate swash plate is fixed with a support frame, wave swash plate mandrel screw fixation.

2 When installing the tilt direction should not flow straight inclined tube (plate).

3 Regular washing, rational management and reduce clogging caused by biofilm soaring.

4. Inclined tube (board) shall bear the plane concentrated load.

5 shall not be fitted with the use of fire in the inclined tube (plate) area.

Fourth, the material:

Resin corrosion equipment for the steel, fiberglass or PP honeycomb inclined tube filler, an inclination of 60 degrees, plagioclase one meter, the inscribed circle diameter of 25 mm to 80 mm, in order to achieve optimal precipitation efficiency

Fruit. Sedimentation is a total of four kinds of specifications to choose from, but also according to the original design of the wastewater test data Sedimentation is different flows are generally required when using the coagulant dosing.

Use:

Sedimentation water purifier can be used as flotation, biochemical processes such as water purification equipment, can also handle a variety of single-stage sewage. For example:

1, electroplating wastewater containing a variety of metal ions in the mixed water, chromium, copper, iron, etc. to reach more than 90% removal after plating generally treated wastewater should be to reach the emission standards.

2, coal mine waste can cause turbidity of 500 to 1500 mg / lift to 5 mg / l.

3, printing and dyeing wastewater color removal 70 ~ 90%, CODcr removal of 50 to 70%.

4, leather and food industry waste a lot of organic matter removal CODcr removal of 50 to 80%.

5, CODcr chemical wastewater removal of 60 to 70 percent, from 60 to 90% color removal, suspended solids to meet emission standards.

Sixth, the process flow diagram:
