Inclined tube sedimentation water purifier

1Inclined tube sedimentation water purifierprinciple

The inclined tube sedimentation purification method is a method of constructing inclined tubes with an inclination angle of 60 degrees above the suspended layer of sludge. Suspended solids, solids, or flocs formed by adding coagulants in the original water accumulate on the bottom surface of the inclined tubes to form a thin layer of sludge, which slides back to the suspended layer of sludge by gravity and then sinks into the sludge collection 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.

2、 Purpose:

The inclined tube settler can be used as a 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 various metal ions, such as copper, iron, zinc, nickel, etc., in electroplating wastewater is over 90%. Generally, electroplating wastewater can meet the discharge standards after treatment.

2. Coal mine and mineral processing wastewater can reduce turbidity from 500-1500 milligrams per liter to 20 milligrams per liter.

3. The color removal rate of wastewater from printing and dyeing, bleaching and dyeing is 70-90%, and the COD removal rate is 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.

3、 Advantages

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.

Inclined tube sedimentation water purifierThe inclined tube sedimentation tank is an efficient combined sedimentation tank designed based on the theory of shallow tank sedimentation, also known as a shallow tank sedimentation tank. The biggest feature is the integration of sedimentation, concentration, and sludge discharge processes. The sludge concentration was successful once, eliminating the concentration tank and occupying a small area. Simplified the process and reduced equipment. Mainly used for various sedimentation and sand removal. In the past decade, it has been applied in water supply and drainage engineering and has become one of the important equipment for water treatment.

The longer the length of the inclined plate and inclined tube, the higher the settlement efficiency. However, the inclined plate and inclined tube are too long, making production and installation difficult. Moreover, increasing the length to a certain extent has limited effect on improving settlement efficiency. If the length is too short, the proportion of the length of the inlet transition section (which refers to the section where the water flow transitions from turbulent flow at the inlet end of the inclined tube to laminar flow) increases, and the length of the effective settling zone decreases accordingly. The length of the inclined tube transition section is approximately 100-200mm.
