sedimentation tank

I. Equipment application
Settling tank inclined pipe is mainly used for various sedimentation and sand removal, and is a widely used and mature water treatment device in water supply and drainage projects for more than ten years. It has the advantages of wide application range, high treatment effect and small occupation area, and is suitable for sand removal at water inlet, precipitation, oil separation and tailings concentration treatment of general industrial and domestic water supply. It is suitable for both new construction projects and reconstruction of existing old ponds, and good economic benefits can be obtained.

II. product feature

1. Large wet cycle and small hydraulic radius.

2. Laminar flow condition is good, particle settling is not disturbed by turbulence.

3. When the inclined pipe length is 1 meter, the effective load is designed according to 3-5 tons/m3. V is controlled in the range of 2.5-3.0 mm/s, and the effluent quality is good.

4. Honeycomb inclined pipe is adopted at the water intake. When the pipe length is 2.0~3.0 meters, it can be operated in high turbidity with 50-100 kg/m3 silt content.

5. The inclined tube sedimentation tank is adopted, and its processing capacity is 3-5 times that of the horizontal sedimentation tank, and 2-3 times that of the accelerated clarifier and the pulse clarifier. The straight pipe is mainly used for high load biological filter, tower biological filter, submerged biological filter (also known as contact oxidation tank) and microbial carrier of biological turntable for biochemical treatment of industrial organic wastewater and municipal sewage.

III. main feature

1. The treatment efficiency is higher than that of activated sludge method, and the general hydraulic load is 100-200 m3/m2, and the organic load is 2000-5000 g/m3, so the occupied area is reduced.

2. The aeration intensity is lower than that of activated sludge method, and there is no need for sludge reflux, so it can reduce power consumption and simplify management.

3. Less sludge, reducing the sludge dehydration and other post-treatment workload.

4. The sludge produced has good settling property, which is beneficial to the removal of suspended substances in the later stage.

5. Strong adaptability, can adapt to different water quality range, water quality, water quality sudden change of the impact load of strong endurance, to maintain a stable treatment effect.

6. As long as scientific operation management is carried out, regular flushing and sewage discharge will not generally cause blockage.
