Abstract
The utility model discloses a flotation-sedimentation tank with a sideward flow inclined plate. The flotation-sedimentation tank comprises a flocculation zone, a water distribution zone and a flotation-sedimentation zone and has the key points that the flotation-sedimentation zone is divided into a gas flotation zone at the upper part and a sedimentation zone at the lower part by a partition plate, the sedimentation zone adopts a sideward flow inclined plate, and one effluent end of the sedimentation zone in the lower part is communicated with the gas flotation zone at the upper part through a dissolved gas release zone. In the flotation-sedimentation tank, the gas flotation zone and the sedimentation zone are horizontally divided, the dissolved gas release zone is arranged behind the sedimentation zone, the course of the release of the dissolved gas happens after the sedimentation of the inclined plate; therefore, the influence of the inclined plate on gas flotation can be eliminated. Meanwhile, the flotation-sedimentation tank with the sideward flow inclined plate integrates the processes of flocculation, sedimentation and gas flotation into a tank, thereby saving the occupied area.
Description
Technical field
The utility model relates to the water treatment building that a kind of employing method of drifting along is handled waste water.
Technical background
Lateral flow inclined plate floating depositing pool area northeastward is widely used, and is developed by air flotation pool, is mainly used to handle low temperature and low turbidity water, also can adapt to the situation of the high turbidity of former water in flood season simultaneously.When former water low temperature, low move according to pneumatically supported mode when turbid, when former water high when turbid by the precipitation mode operation.Flow through earlier molten gas of the former water of existing lateral flow inclined plate floating depositing pool discharges the district, enter air supporting and precipitation common area again, when operation air supporting, molten gas discharges micro-bubble that the district produces can be gathered into bubble about diameter 1mm at sloping plate unit, the hydraulic disturbance that this bubble produces in uphill process can be smashed flco, this bubble is floating simultaneously can produce impact force to scum layer and cause scum layer to fall slag, more than two aspects all can influence the air supporting effluent quality.
The utility model content
The purpose of this utility model is to provide a kind of lateral flow inclined plate floating depositing pool that can eliminate swash plate to the air supporting disadvantageous effect, can guarantee stable effluent quality under the unsettled situation of raw water quality.
For achieving the above object, the technical solution of the utility model is as follows: a kind of lateral flow inclined plate floating depositing pool, comprise flocculation zone, water distributing area and the district of drifting along, it is characterized in that: the described district of drifting along is divided into the air flotation zone on top and the settling region that lateral flow inclined plate is adopted in the bottom by dividing plate, and the settling region of bottom is communicated with the air flotation zone on top by molten gas release district at an end of water outlet.
As further optimization, for convenience of spoil disposal, the bottom of described floating depositing pool is provided with mud-removing bucket.
As further optimization, for water surface is scraped slag, an end of described air flotation zone is provided with ash pit, and the slag scraper that is arranged on the air flotation zone top scrapes scum silica frost in the ash pit.
As further optimization, catchment for convenience, whole apparatus structure compactness, the centre of described air flotation zone is provided with a water leg, and the water outlet of the perforated pipe that the air flotation zone bottom is provided with flows into water in the water leg.
As further optimization, in order to make further sediment, the end of described water leg is provided with effluent weir.
The utility model can adapt to the unsettled situation of raw water quality, operation precipitation-air-float technology when former water low temperature, low turbid, high algae, oil-containing; When former water height is turbid, but the isolated operation depositing technology is saved working cost, also can move precipitation-air-float technology, guarantees effluent quality.The utility model separates air flotation zone and settling region level, molten gas is discharged the district place after the settling region, and the process that molten gas discharges occurs in after the sloping plate deposition, so can eliminate swash plate to pneumatically supported influence.Simultaneously, the utility model is integrated in a pond body with flocculation, precipitation, air-float technology, has saved occupation of land, compact construction.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of A-A among Fig. 1.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described.
As depicted in figs. 1 and 2, this floating depositing pool mainly comprises the flocculation zone 4 of leading portion, the water distributing area 5 in stage casing, the air flotation zone 1 on back segment upper strata and the settling region 2 of back segment lower floor.Adopt dividing plate 13 levels to cut off between air flotation zone 1 and the settling region 2, the cavity only is set on the wall endways makes it to be communicated with and form molten gas and discharge and distinguish 3 with the air flotation zone 1 on top.
Flocculation zone 4 can adopt conventional waterpower flocculation mode, and conventional perforation tracery wall water distribution mode is adopted in the water distribution of water distributing area 5, makes water enter the settling region from hole, and settling region 2 adopts the lateral flow inclined plate sedimentation mode; Air flotation zone adopts slag scraper 7 that surface scum is scraped to ash pit 6, adopts outside stream mode is discharged the pond, and air flotation zone 1 bottom is provided with perforated pipe 8 and catchments.
The bottom that the water distributing area 5 in flocculation zone 4, stage casing, settling region 2 and molten gas discharge district 3 all is provided with mud-removing bucket 11, adopts the perforated pipe spoil disposal.
Former water dosing is carried out throwing out after water inlet pipe 14 enters flocculation zone 4, form big alumen ustum, then through the perforation tracery wall of water distributing area 5, entering settling region 2 precipitates, sedimentary mud slips in the mud-removing bucket 11 and stores, and settling region 2 water outlets are risen after molten gas discharges district 3 through the perforation tracery wall again and entered air flotation zone 1.When operation precipitation-air-float technology, dissolved air release 12 and dreg scraping buggy 7 move simultaneously, and when only moving depositing technology, dissolved air release 12 and dreg scraping buggy 7 are not worked.Perforated pipe 8 water outlets are adopted in the air flotation zone bottom, and perforated pipe 8 is communicated with water leg 9, and water leg 9 ends set out mill weir 10, adopt the overflow water-out manners.Water leg 9 water outlets are connected to down treatment process one through rising pipe 15.
The utility model can be handled low temperature, low turbid former water, contain the former water of algae, oily(waste)water, can be applicable to fields such as sea water preprocessing, iron and steel enterprise's whole plant factory effluent pre-treatment.
More than by specific embodiment the utility model has been done detailed description, but do not constitute restriction of the present utility model, any technical scheme that drops within the utility model claim scope all is subjected to protection of the present utility model.
