Slant tube sedimentation electroplating wastewater treatment equipment

[Introduction]

The IPS Type Inclined Tube Setter is a device composed of inclined tubes with a tilt angle of 60 degrees above the suspended layer of sludge. Suspended solids, solids, or flocs formed by adding coagulants in the raw water accumulate on the bottom surface of the inclined tube to form a thin layer of sludge, which slides back to the suspended layer of sludge by gravity and then sinks into the sludge hopper. Discharged into the sludge tank through the sludge discharge pipe for further treatment or comprehensive utilization. The supernatant gradually rises to the collection pipe and can be discharged directly or reused.

Slant tube sedimentation is made based on the sedimentation principle of removing dispersed particles in a horizontal sedimentation tank. By adding inclined pipes in the pool, the hydraulic radius is reduced while increasing the wet circumference of the water passage section of the pool. Therefore, at the same horizontal flow velocity V, the Reynolds number Re of the water flow can be greatly reduced, thereby reducing turbulence and promoting sedimentation. In addition, adding inclined pipes can shorten the distance of particle precipitation, reduce precipitation time, and improve precipitation efficiency.

1. Simple structure, no vulnerable parts, durable, and reduces maintenance

2. Stable operation and easy operation

3. Less power and energy saving

4. Land saving, low investment, fast deployment, and high efficiency

5. The lower part of the inclined plate sedimentation device is equipped with a mud hopper, and the accumulated mud can automatically fall into the slag hopper, which facilitates the discharge of mud and reduces the labor intensity of slag cleaning.

6. According to the water quality and user requirements, mechanical sludge discharge can also be used, such as screw conveyor sludge discharge, scraper sludge discharge, etc.

7. The inclined plate sedimentation tank has a small footprint, only 1/4 of the length of a horizontal sedimentation tank, and the sedimentation efficiency can be increased by 3-5 times.

【 Material 】

Carbon steel Q235A, with internal anti-corrosion using epoxy asphalt, can also be lined with rubber, plastic, fiberglass, PTFE, etc;

1. Surface load of inclined plate settler: 3-15m3/m2 · h;

2. The effective coefficient of the area of the inclined plate clarifier, μ: 0.7-0.8;

3. The inclination angle θ of the inclined tube clarifier is generally 60 °;

4. The length of the inclined plate and inclined tube of the inclined sedimentation tank is generally 1000mm;

5. Hydraulic retention time of inclined tube clarifier: 25-60 minutes;

[Scope of use]

It can be used as supporting equipment for water processes such as air flotation and upgrading, as well as for single-stage treatment of various types of wastewater.

1. The removal rate of mixed wastewater containing multiple metal ions, such as copper, iron, zinc, nickel, etc., in electroplating wastewater is above 90%. Generally, electroplating wastewater can meet the discharge standards after treatment.

2. Coal mine and mineral processing wastewater can reduce turbidity from 500-1500 mg/L to 5 mg/L.

3. 印染、漂染等废水色度去除率70-90%，COD去除50-70%

4. The removal of a large amount of organic matter from wastewater in industries such as leather and food, with a COD removal rate of 50-80% and a solid impurity removal rate of over 90%.

5. The COD removal rate of chemical wastewater is 60-70%, the chromaticity removal rate is 60-90%, and the suspended solids meet the discharge standards,

Determine the specific specifications and dimensions of the inclined plate clarifier/inclined tube clarifier equipment based on the sedimentation performance, surface load, and residence time of the customer's water quality.
