Embodiment
Specific embodiment of the utility model, referring to figs. 1 through Fig. 2, a kind of sewage from catering business treatment unit comprises:
Oil trap
This device adopts three grades of oil removal methods, and oil trap adopts the deflector type design, increases the sewage flow process, makes oily water separation more thorough.Every grade of oil separating plate is equipped with a plurality of water distributing pores, makes current even, and adopts low-Gao-low arrangement mode, and grease and scum silica frost and bigger suspended substance are isolated in the upper strata, and throw out is isolated at the bottom of the oil trap.Be provided with oil reservoir simultaneously, the special oil-collecting device of process is stored in oil reservoir with the oil slick on oil trap upper strata, is convenient to reclaim.
First step oil trap 1 is provided with water-in 11 and second stage oil trap 2 adopts oil separating plate 12 to be separated by, and oil separating plate 12 nearly bottoms, pond are provided with the water outlet of a row through hole 121 as first step oil trap 1.After sewage entered first step oil trap, (2～5mm/s) flow through this pond, in flow process, float to the water surface on the grease of density less than water, and density is sunken at the bottom of the pond greater than the granule foreign of water with lower horizontal flow velocity.And upper strata grease and scum silica frost and bigger suspended substance are tackled by first step oil separating plate, prevent that it from entering second stage oil trap.
Second stage oil trap 2: and adopt oil separating plate 21 to be separated by between the third stage oil trap 3, oil separating plate 21 upper part are provided with a row through hole 211 as second stage oil trap water outlet.The function in this pond and principle and first step oil trap 1 are similar, and the part oil slick and the throw out of coming impacted in main interception from first step oil trap.
Third stage oil trap 3, and adopt oil separating plate 31 to be separated by between the settling tank, a row through hole is set as third stage oil trap water outlet on the oil separating plate 31,50mm at the bottom of the end distance pond under the posticum.The function in this pond and principle and second stage oil trap are similar, and further interception is impacted the part oil slick and the throw out of coming from second stage oil trap, and it is minimum that the oil content of wastewater that enters settling tank is dropped to.
Oil reservoir 4 and oil header 13: function: collect the storage grease.Oil header 13 is arranged at the top of three oil traps 1,2,3, and this oil header 13 is 60 °～90 ° notch at the side open arc wide of tube wall along length.Oil header can rotate around axis.During oil extraction with below the fluting directional steering horizontal plane of oil header collecting oil slick, and oil slick is imported oil reservoir.The oil header horizontal direction is 3 °～5 ° a gradient, is convenient to oil slick and imports oil sump 4.
Settling tank 5, function: make the suspended substance precipitation in the water.What settling tank adopted is the gravitational separation process principle.Current flow out oil trap 3 backs and enter settling tank 5 from the bottom.Settling tank 5 is respectively equipped with two-layer honeycomb filler 51 and tilts to place, and make current tilt to rise from honeycomb filler lower end edge hole, and lift velocity is not higher than 0.9mm/s.Most of particle suspensions polymerization becomes big postprecipitation in the uphill process.Bottom honeycomb filler lower end level height will be higher than the water-in 311 of settling tank, required time when making current have enough surge time to guarantee the precipitation of suspended substance.
Filtering basin 6: function: the suspended substance in the interception water.This device adopts the two-stage filtration pond.Current enter first step filtering basin 61 after settling tank flows out.The flow direction of first step filtering basin is for from the bottom up, and the bottom of filtering basin at the corresponding levels is provided with water distribution board, can guarantee that current pass through filtrate and filtrate equably and can not fall into settling tank; Filler is the macrobead zeolite filler, and when current were flowed through these filtering basin, water flowed out this pond by the zeolite slit, and the suspended substance in the water is tackled by zeolite.Current flow to second stage filtering basin 62 by second water distribution board and filter cloth after leaching zeolite filler, and the filler in the filter tank, the second stage is the small-particle zeolite filler, and water outlet continues to rise, passing through triangle overflow plate 63, can make and filter evenly, guarantee filter effect, play the effect of the buffering water yield simultaneously.What first and second grade filter tank filler zeolite was used is active zeolite, be that natural zeolite forms through multiple special process activation, not only the slit between its zeolite is littler, can further tackle the suspended substance in the water, and its absorption property is stronger than natural zeolite, and ion-exchange performance is also better.Can not only remove turbidity, colourity, peculiar smell in the water, and deleterious heavy metal in the water (as: chromium, cadmium, nickel, zinc, mercury, iron ion etc.) and organism (as: phenol, phenyl-hexachloride, dichlorodiphenyl trichloroethane, three nitrogen, ammonia nitrogen, phosphate anion etc.) had the absorption exchange interaction, help removing various Micropollutants in the water, and water-leach liquor does not contain poisonous yet.
First step biological filter 71: function: grease and suspended substance in the absorption interception water, reduce COD.When current after 63 water outlets of triangle overflow plate, enter first step biological filter 7, its bottom is evenly distributed with medium-soft 3 D elastic filler 71, this filler has long service life, start that biofilm is fast, demoulding upgrades easy, anti-high loading and impacts, advantages such as obvious processing effect, operational management be easy, do not stop up, not conglomeration.The organism of biology on the filler in can well water of decomposition can cushion the impact that the instantaneous high flow capacity of sewage from catering business brings on the other hand.Bottom, this filter tank is provided with a water pipe, and the pipe low side has effluent trough, and pipe is provided with a ball valve 72, by union lever can by-pass valve control switch, be convenient to the draining and the cleaning of biological filter, the second stage.
Biological filter, the second stage 8: function: grease and suspended substance in the absorption interception water, reduce COD.This biological filter is provided with four layers of filler, current flow from bottom to top, the first layer and the 4th layer are filled with MODIFIED PP fibrous packing 81 and 83 respectively, can adsorb small oil droplet, simultaneously also can adsorb the molecule suspended substance once more, the second layer, the 3rd layer are multiaspect hollow ball filler 82, and there is a reinforcing ring at this multiaspect hollow ball middle part along whole girth, respectively there are 12 ball clacks the ring upper and lower part, is radiation along central shaft and arranges.This ball high cycle speed, blade is big, resistance is little; Specific surface area is big, and current guarantee that through behind the two-layer filler effluent quality turbidity, grease, COD reach three grades of emission standards.Too much for preventing the filling surface pollution substance simultaneously, sink at the bottom of the pond after the combination of macrobead suspended substance, so be provided with skim gate 84, be convenient to bottom mud and regularly remove in this bottom, filter tank.For the ease of the routine cleaning of PP fibrous nodules and multiaspect hollow ball, each layer of biological filter is independent stratum, separates with water distribution board respectively, can leave the water respectively in case of necessity.Be convenient to maintenance personnel's dismounting and cleaning like this.Behind four layers of filler, after process one deck was drilled with the water distribution board of several apertures, water outlet effluxed from water outlet 85.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
