Technical field
A kind of sewage disposal equipment for separating liquid from solid is the utility model is related to, especially a kind of overall structure is simple and reliable,
Ingenious in design, reaction is abundant, is not easily blocked, the new batch-type air-dissolving air-float equipment for separating liquid from solid of good separating effect.
Background technology
Air flotation technology is a kind of efficient solid-liquid separation technique, widely applies to oil-containing, suspension, high concentration organic waste
In the pretreatment of water, such as the processing of the industry waste water such as oil refining, machining, printing and dyeing, papermaking, agricultural chemicals, it is mainly used in removing and gives up
In water proportion be less than or close to 1 oil, emulsion and suspended particulate substance.Compared with the precipitation method, Bubble-floating Method separative efficiency is high,
Dissolved air flotation ability is about precipitate separating capacity 4~5 times；Bubble-floating Method constantly to Aeration in the water, have preaeration, decolouring,
Reduce COD value and preferable ammonia nitrogen degradation function；Air supporting upper strata scum silica frost moisture content is low, can reduce sludge treatment expense.
Traditional Bubble-floating Method species is a lot, but changes ten thousand times without leaving the original aim or stand, and mainly includes three processes：The generation of bubble, bubble with
The adhesion of particle and flocs float separation.Different according to the producing method of bubble, Bubble-floating Method is broadly divided into three kinds：Electrolytic gas
Floating, scattered gas air supporting and air-dissolving air-float.Wherein bubble phase caused by dissolved air flotation is uniform, tiny for dissipating gas air supporting, to pollution
The removal efficiency of thing significantly larger than dissipates gas air supporting, while it is more more convenient than electrofloatation in terms of operation, operation and economy
With it is reasonable, therefore be most widely used.
But traditional dissolved air flotation has the following disadvantages：(1) in Disengagement zone bubble adhesion pollutant to upstream, and locate
Water is had a great influence to flowing down by hydraulics, raw water quality water after reason, and fluctuation of service, separating effect is far below theory
Effect；(2) traditional air-dissolving air-float is narrow and complicated using dissolved air release runner, is very easy to block, although many releases
There is flushing measure, but effect is generally undesirable；(3) traditional air-dissolving air-float reaction tank, contact zone and Disengagement zone are individually set up,
Take up an area larger；(4) for traditional air-dissolving air-float reaction tank by the design of sedimentation basin design parameter or reactionless pond, this is all unsatisfactory for air supporting
Requirement of the journey to reaction.In a word, traditional air-dissolving air-float is had a great influence by hydraulics, raw water quality water, and release is easily stifled,
The extent of reaction is unreasonable, fluctuation of service, and separating effect is relatively poor.
