Abstract
The utility model relates to a device for treating suspended oil residue in sewage according to a chemical method. The device comprises an air floatation precipitator, a filter and a suspension reactor, wherein sewage discharged by the air floatation precipitator is filtered by the filter for the second time, and then output to the reactor; an oil discharge outlet (15) is formed in the top of an air floatation precipitation reactor; inclined baffle plates (14), which are arranged in a crossed manner, are arranged on the upper and the lower walls in the air floatation precipitation reactor; a high pressure gas spray pipe (13) is arranged between each two baffle plates (14); a baffle plate (24), of which the lower part is hung in the air, is fixed in the filter; a vertical filter plate (22) and a horizontal filter plate (23) are arranged on the left side of the baffle plate (24); and a plurality of inclined filter plates (26) with opposite inclination directions are arranged on the baffle plate (24). The device has the characteristics of high sewage treatment efficiency and low float sludge yield.
Description
Technical field
The utility model relates to a kind of waste disposal plant, relate to specifically a kind of be applied to urban environmental protection utilize chemical process dispose of sewage in the device of the suspension dregs of fat.
Background technology
At present, various industries such as catering industry, food-processing industry etc. are through the higher sewage of regular meeting's discharging oil-containing quarrel composition, and the present waste disposal plant overwhelming majority is made up of oily water separation and filtration unit.These existing treatment unit in use come to light and have problem: because the density of oil is less than water; Therefore most of dregs of fat are suspended in the sewage surface; Simultaneously in order to guarantee that WWT can reach standard; Need add in a large number demulsifying flocculant efficiently in the treating processes, cause handling the back system and produce a large amount of scum silica frost, and do not have proven technique at present for the processing of scum silica frost.In sum, there is the problem that oil removal efficiency is not high, the scum silica frost generation is excessive in existing urban sewage treating device when handling the higher sewage of oil-containing slag ingredient.
Summary of the invention
In order to overcome the existing waste disposal plant deficiency that oil removal efficiency is low, the scum silica frost generation is big when handling the higher sewage of oil-containing slag ingredient; The utility model provide a kind of utilize chemical process dispose of sewage in the device of the suspension dregs of fat, this device has sewage treating efficiency height, characteristics that the scum silica frost generation is little.
The technical scheme of the utility model is: a kind of utilize chemical process dispose of sewage in the device of the suspension dregs of fat; Comprise air supporting settling vessel, strainer and suspension reactor; The sewage of being discharged by the air supporting settling vessel outputs to suspension reactor after by the strainer secondary filtration; The top of described air supporting precipitation reaction device is provided with oil discharge outlet, and lower wall is submitted the dividing plate that fork is arranged with inclination on the air supporting precipitation reaction device inside, is provided with the high pressure gas jet pipe between per two dividing plates;
Described strainer internal fixing has the unsettled baffle plate in bottom, and the baffle plate left side is provided with vertical filter plate and horizontal filter plate, and the baffle plate right side is provided with the opposite inclination filter plate of several vergence directions.
The utlity model has following beneficial effect: owing to take such scheme, air supporting precipitation reaction device evenly is provided with the high pressure gas jet pipe simultaneously at the dividing plate of along continuous straight runs inclination arranged in a crossed manner in the middle of per two baffle plates; Through the jet pipe inject high pressure gas that makes progress; Sewage is in the effect current downflow of gas, and the restriction of the dividing plate that is tilted has again reduced it to product place mobile speed; Make oily water separation time lengthening, improved oily water separation efficient.In addition; Come on the water pipeline to be provided with the medicine inlet that adds composite flocculant at said air supporting precipitation reaction device; Therefore, sewage is existing because also there be cohesion and the come-up effect of micro-bubble for oil droplet in the natural subsidence that the profit density difference produces in flow process.Simultaneously, the sewage of being discharged by air supporting precipitation reaction device is again by the strainer secondary filtration, and the baffle plate in the strainer reduces water flow velocity, under the effect of vertical, level, the triple filter plates of inclination, makes oil removal efficiency high, and the scum silica frost generation is little.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
11-air supporting precipitation reaction device tank body among the figure, 12-reactor drum water-in, 13-high pressure gas jet pipe, 14-dividing plate; 15-oil discharge outlet, 16-are prevaricated the device water outlet, the 20-filter body; 21-strainer water-in, the vertical filter plate of 22-, the horizontal filter plate of 23-; The 24-baffle plate, 25-inclination filter plate, 26-strainer water outlet.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, a kind of utilize chemical process dispose of sewage in the device of the suspension dregs of fat, comprise air supporting settling vessel, strainer and suspension reactor, the sewage of being discharged by the air supporting settling vessel is exported suspension reactor after by the strainer secondary filtration.The right ends of described air supporting precipitation reaction device tank body 11 is respectively equipped with reactor drum water-in 12 and reactor drum water outlet 16, and water-in is higher than water outlet.The top of reactor drum is provided with oil discharge outlet 15; Several oil discharge outlets 15 connect delivery pipeline; Lower wall is submitted fork and is arranged with the dividing plate 14 of inclination on the inside reactor, and as preferably, the height of dividing plate 14 is 2/3rds of a height for reactor; Be provided with high pressure gas jet pipe 13 between per two dividing plates 14, high pressure gas jet pipe 13 connects the external high pressure source of the gas.
The top of described filter body 20 is provided with the lid that can open; And the size of lid can guarantee that inner screen plate takes out, and the right ends of filter body 20 is respectively equipped with strainer water-in 21, strainer water outlet 26, and filter body 20 internal fixation have the unsettled baffle plate in bottom 24; Two spaces about baffle plate 24 is divided into strainer; Be beneficial to the screen plate that different directions is set on the one hand, reduced the flow velocity of water on the other hand, make filtration more abundant.Baffle plate 24 left sides are provided with vertical filter plate 22 and horizontal filter plate 23; Wherein vertical filter plate 22 and horizontal filter plate 23 are processed by filter screen, can link together, and can be taken out by filter body 20 and clean; Baffle plate 24 right sides are provided with the opposite inclination filter plate 26 of several vergence directions; Water in the strainer is from bottom to top through baffle plate 24 its flow tendency of back, passes through the filtration of inclination filter plate 26 again, makes dregs of fat content still less.
This device is delivered to suspension reactor after by air supporting settling vessel, strainer double filtration again, improved oil removal efficiency greatly, and the scum silica frost generation is few.When using the higher sewage of this apparatus processes oil-containing slag ingredient,, make that filtrate can be by thorough regeneration, have oil removal efficiency height, characteristics that the scum silica frost generation is little with follow-up suspension reactor and the acting in conjunction of sump oil strainer.
