In order to realize purpose of the present invention, the invention provides the rotary drum grid that a kind of Wastewater Pretreatment is used, it comprises drive unit 9, support 6 and rotary drum 2, described drive unit 9 links to each other with rotary drum 2, drive rotary drum 2 and prolong its axis direction rotation, wherein, described rotary drum 2 is a hollow, the dreg collecting slot 5 that is complementary with rotary drum 2 shapes is installed in rotary drum 2, in dreg collecting slot 5, is provided with defeated slag device 4; Described rotary drum 2 front ends are provided with water-in 17, and its rear end is provided with water outlet 18, are provided with flushing arrangement 3 above described rotary drum 2, and rotary drum 2 belows are provided with bearing; 6 pairs of rotary drums 2 of described support fix, support, are connected with defeated slag device 4, and the top of described grid rotary drum is provided with and fails the slag notch 8 that slag device 4 links to each other; At the forward and backward probe 7 that installs and measures respectively of grid, water eliminator 1 is installed in rotary drum (2) front end before the described grid.
According to a kind of preferred embodiment, in described rotary drum 2, be provided with the filtering net 14 that is complementary with rotary drum 2 sizes, described filtering net 14 is dismountable.
According to the utility model, described filtering net 14 can be the filtering net that is made of silk screen, orifice plate or grizzly bar.
Preferably, the aperture of above-mentioned filtering net 14 is 0.5～1.2mm, more preferably 0.8mm or 1.0mm.
Above-mentioned grid can be made of grizzly bar, filter screen or orifice plate, and its material is the SUS304 stainless steel for example, also can adopt the material of other antiseptic properties as required, as SUS316.
The bearing of described rotary drum grid preferably adopts Nonlubricated bearing, and for example the MGC alloy bearing need not to lubricate under water, and running is stable, long service life.
According to a kind of preferred embodiment, described flushing arrangement 3 adopts anti-blocking sprayers, can directly adopt the grid of drawing from described water outlet after water clean.
Particularly, grid tilts to be installed in the irrigation canals and ditches, and the angle of inclination is 35 °.During equipment operation, drive-motor drives rotary drum and defeated slag device running, floating matter in the filtering water and other impurity, floating matter and impurity warp are again failed slag device press dewatering after slag-drip opening is discharged, and the water after filtering is exported from water outlet through rotary drum, enter follow up device, for example enter membrane bioreactor.Flushing arrangement washes self-cleaning to rotary drum when rotary drum turns round, the filtering surface to rotary drum cleans on the one hand, simultaneously filter residue is flushed in the dreg collecting slot.Flushing arrangement adopts anti-blocking sprayer, and surging force is strong, and the flushing area is big, can directly adopt from the water of grid rear portion output and wash.Grid is a discontinuous running, also can continuous operation.
[beneficial effect]
Wastewater Pretreatment cell structure of the present invention practicality, be easy to safeguard.Its parts adopt stainless steel to be made, and antiseptic property is strong, and the life-span is long; Adopt Nonlubricated bearing under water, stable and reliable operation need be keeped in repair hardly.Larger particles and fibrous matter that it can effectively remove in the waste water to be contained prevent the damage and the obstruction of MBR film, and good filtration effect has reduced the load of subsequent disposal (as film filter); By the self-stip function of flushing arrangement, can keep good strainability.

[embodiment]
Following embodiment is described with reference to the accompanying drawings the utility model.
Described Wastewater Pretreatment grid is that stainless steel constitutes, equipment length overall 6100mm, and wide 1200mm installs and fixes by support 6.Water eliminator 1 links to each other with irrigation canals and ditches before the grid, and its waste water sealing before with rotary drum makes water-in 17 concentrated the enter rotary drums of waste water from being positioned at the rotary drum center.Rotary drum 2 diameters
Long 1160mm is provided with dreg collecting slot 5 and filtering net 14 in the rotary drum 2, be provided with defeated slag device 4 in the dreg collecting slot 5, and the other end of defeated slag device 4 is identical with slag notch 8.Above rotary drum, be provided with anti-blocking flushing arrangement 3; End at the rotary drum grid is installed drive unit, in order to drive the running of rotary drum and defeated slag device.Before and after grid, be separately installed with measuring sonde 7, in order to the water level before the measurement grid, behind the grid.
During the grid works better, flowed into from water-in 17, behind rotary drum filtering net, grid filtration,, flow out to irrigation canals and ditches through water outlet 18 from the inboard outside that flows to of rotary drum by filtrate body (waste water).Like this, dirt (larger particles in the waste water and fibrous matter) is dammed in rotary drum filtering net 14 inboards, and along with increasing of the thing that dams, the liquid level difference of water inlet 17 and water outlet 18 also increases (water outlet 18 liquid levels are the irrigation canals and ditches liquid levels) thereupon.When liquid level difference reaches certain numerical value, show that filtering net 14 is blocked, should clean this moment.During cleaning, rotary drum rotates, open the high pressure washing pump of flushing arrangement, make through water behind the filtering grid and after the high-pressure pump supercharging, the rotary drum screen cloth is cleaned through anti-blocking sprayer, when reaching cleaning performance, before the grid, liquid level difference is less than rating number behind the grid, rotary drum stops operating, and flushing arrangement stops flushing thereupon.In the grid work, if liquid level difference is always less than rating number before the grid, behind the grid, then grid can turn round and washes according to temporal order.
Wastewater Pretreatment grid of the present invention is applicable to from waste water removes fiber fines and solid impurity, floating substance, is a kind of less energy-consumption, grid filtration device efficiently.It is about 70%～90% to the clearance of the suspended solid in the former water, and the filter for waste water pretreatment of process present embodiment is the former water process filtration of 400～500mg/L to the SS index, and the SS concentration of actual water outlet is 100～150mg/L, and effect is obvious.
