Abstract
The utility model relates to a combined dining sewage purifier, which can continuously separate liquid which contains greasy dirt by using the principles of filtering, air flotation, and adsorption. The utility model is composed of a filter screen plate structure, an air flotation structure, and an absorption structure which are communicated by pipelines. Suspended substances in greasy water are removed by a filter screen plate (3), the greasy water enters an air flotation trough (4), water and oil are layered, the oil is removed by an oil skimmer (6), the water is pressed into an absorption box (12) by a pressurizing water pump (11), and the water is discharged after oil removing and decontamination. The content of oil in water which is discharged is below 20 mg/L, and the content of the suspended substances is below 30 mg/L.
Description
The utility model relates to the processing of sewage.It is a kind of principle of utilizing filtration, air supporting and absorption, separates the device that contains greasy dirt dirty liquid body continuously, is applicable to the processing of the washing sewage effluent of catering trade.
To containing the waste disposal plant of suspended substance and oil in the water, structure mainly contains grid, web plate filters and the swash plate tube settling at present.The former is main according to damming mechanism, and the latter mainly utilizes gravitational settling mechanism to remove suspended substance.Oil handling in the sewage is mainly adopted the absorption of air supporting and oleophilic drainage material, air supporting relies on gravity stratification, and the latter belongs to physical adsorption, and what remove only is showy oil in the sewage, also not having at present suitable device for the oily water processing of high density makes the concentration of handling oil in the sewage of back reach emission standard, food such as catering trade, the washing water of tableware, existing animal grease in the water, food oil is arranged again, and with oil slick, the form of grease and oil in water emulsion exists, its concentration can be up to thousands of milligrams per liters, and catering trade limits by site condition often, do not have suitable device again, can only enter water drain after coarse filtration, the concentration of oil is still at hundreds of milligrams per liters in the discharge water.
The purpose of this utility model is to be to provide a kind of simple, easily row, and processing efficiency height, can reach the built-up type sewage from catering business cleaner of emission standard.
The purpose of this utility model is achieved in that
This device carries out tertiary treatment to sewage from catering business, so be provided with screen pack structure, air floating structure and adsorption structure three parts.The screen pack structure comprises the casing of belt track, and into sewer line, oil drain valve, wash water valve are arranged on the casing, and two blocks of above active filters web plates are arranged in addition.Air floating structure comprises that cell wall has air flotation slot, oil skimmer vessel, reliever, dissolving, dissolved air water pump and the oil trap of a upflow tube.Air flotation slot is near the casing of screen pack structure, and a shared side box body, and oil skimmer vessel is contained in air flotation slot top, the shared opposite side casing of oil trap and air flotation slot.In comprising, adsorption structure adorns the adsorption box and the filtered water tank of several oleophilic drainage sorbing materials.The screen pack structure adopts water distributor with holes to be connected with air flotation slot.Air flotation slot is connected with adsorption box tube road, and a pressure pump is arranged therebetween.
The active filters web plate uses bolted in double-deck band steel by the wire cloth of different meshes.
Adsorption box is an airtight withstand voltage casing, and sorbing material is made up of two kinds of materials in the adsorption box, is separated by web plate with holes therebetween.
Need to prove: 1, adopt several gradable filtrations of active filters web plate, to reduce the probability that web plate stops up, the active filters web plate inserts along track from the casing top, for being is convenient to install clean; 2, the reliever of air floating structure adopts the bull porous, makes the dissolved air water diffusion evenly, helps the oil droplet come-up; 3, oil skimmer vessel is set above air flotation slot, to remove oil slick; 4, the cell wall of air flotation slot top is provided with a upflow tube, mainly plays the backflow effect and makes sewage level constant height in the air flotation slot; 5, adsorption box adopts airtight withstand voltage casing, mainly for to entering the liquid supercharging of casing, to reduce the volume of adsorption box; 6, select the sorbing material of several oleophilic drainages in the adsorption box,, can adsorb oil in water emulsion again in order that can adsorb oil slick.
The utility model compact construction, easy to operate, can remove the suspended substance and the oil that separate in the sewage continuously, and the processing efficiency height.Can offer certain restaurant of 50 simultaneously is example, and average daily water displacement is 12m
3/ day, 6 hours activity durations, concentration of suspension and oil are all at thousands of milligrams per liters in the draining.Now selecting treatment capacity for use is 2m
3This device of/h, plant area 1.5m
2, 3.5 kilowatts of hour current consumption send an employee part-time every day, and total operating time was less than 20 minutes, and the oil after handling in the draining is less than 20mg/L, and suspension content is lower than 30mg/L.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the schematic top plan view of this device.
Wherein: 2 is oil drain valve, and 3 is the active filters web plate, and 4 is air flotation slot, and 5 is reliever, and 6 is oil skimmer vessel, 7 is oil trap, and 8 is upflow tube, and 10 is delivery pipe, and 11 is pressure pump, and 12 is adsorption box, 13 is water distributor, and 14 is dissolving, and 15 is the dissolved air water pump, and 9 is casing.
Fig. 2 is the A-A cross-sectional schematic.
Wherein: 10 is delivery pipe, and 12 is adsorption box, and 14 is dissolving, and 15 is the dissolved air water pump, and 16 is filtered water tank,
Fig. 3 is the B-B cross-sectional schematic.
