Product Description

The shallow air floatation unit consists of an air flotation tank body, a water distribution bucket mechanism, a sludge bucket mechanism, a rotating frame mechanism, a water distribution pipe mechanism, a slag skimming mechanism, a water level adjustment mechanism, a clean water outlet mechanism, a driving and skimming mechanism, a rotating current collector, It is composed of electric control box, walkway board, guardrail, accessories, micro-oxidation strong dissolved gas system, micro-bubble generation system, etc.

Working principle

The raw water to be treated is sent to the central water inlet pipe by the lift pump, and the dissolved air and medicinal liquid are pumped to the central water inlet pipe for mixing, and then the water is evenly distributed into the air flotation tank through the water distribution pipe, and the skimming mechanism and the main engine drive mechanism Synchronous movement, there is no dead water area, and it moves while rotating, so that the scum is collected and discharged out of the pool through the central mud pipe. The clean water in the pool is drained from the center through the clean water collection pipe, which also moves synchronously with the drive mechanism of the main engine. The clean water pipe and the water distribution pipe are separated by the water distribution mechanism and do not interfere with each other. The sediment at the bottom of the pool is scraped into the mud bucket by the scraper and discharged regularly.

Advantage

1. The purification tank is shallow, and the residence time of sewage in the air flotation tank is only 3~5min, but there is enough scum storage space on the surface, which is especially suitable for the treatment of high-concentration sewage.

2. Unique dissolved gas system design, small volume, high dissolved gas efficiency and compact structure. The equipment occupies a small area and has high efficiency.

3. Large processing capacity, surface load 8~15m/m/n.

4. The floor area is small, or it can be used as an overhead, stacked or set on a building.

5. There is no automatic water level adjustment device, the flow adaptability is large, and the scraped scum has a high solid content.

6. The assembled structure is convenient for transportation, installation and relocation.

7. High rigidity, only one "well" shaped concrete beam is needed to support it, no platform needs to be constructed, and the civil construction cost is low.

8. There are three types of carbon steel (stainless steel in key parts), part of stainless steel, and all stainless steel. All carbon steel is sandblasted with special heavy-duty anti-corrosion treatment, which is resistant to acid and alkali corrosion, and is in good condition after ten years of use.
