Abstract
The invention relates to the technical field of waste water treatment, in particular to a filter for waste water pretreatment, which consists essentially of a shell and a filter element. The filter can filter relatively large particles and fiber substances in waste water, carry out the pretreatment of waste water to protect a membrane reactor in a process of waste water treatment and prevent an MBR membrane from being damaged and blocked. The filter for waste water pretreatment of the invention has simple structure, is easy for manufacturing and maintenance and has good filtering effect.
Description
[technical field]
The invention belongs to technical field of waste water processing.More specifically, the present invention relates to a kind of filter that is used for Wastewater Pretreatment.
[background technology]
The film biofilter is a kind of novel recycled water production equipment of developing in recent years, this equipment binding film isolation technics and traditional wastewater biologic treating technique, efficient centrifugation with film replaces tradition precipitation and filter process, make activated sludge particles and most microorganism in the waste water can be retained in the biological reaction pool, through after the centrifugation of film, clear liquid is extracted out from the film silk by self priming pump, so can obtain higher sludge concentration in the reaction tank.Compare with traditional sewage water treatment method, its floor space is little, stable effluent quality, and can elimination overwhelming majority pathogenic microorganism.
Yet the film biofilter has strict requirement to preliminary treatment, for larger particles and some fibre in the anti-sealing cause the damage and the obstruction of MBR film, the sewage pretreatment filtering device must be set before the film biofilter.The sewage pretreatment filtering device is a lot of at present, and certain effect is all arranged, but does not also have special special filtering device at film biofilter technology.
[summary of the invention]
[problem that invention will solve]
The purpose of this invention is to provide a kind of filter for waste water pretreatment, it can effectively remove larger particles and fibrous matter in the waste water, has advantages such as manufacturing process is simple, is applicable to as the pretreatment unit before the film biofilter.
[technical scheme]
In order to realize purpose of the present invention, the invention provides a kind of filter for waste water pretreatment, it comprises housing, water inlet, delivery port are arranged on the described housing, be positioned at the slag-drip opening of described housing bottom and be positioned at the flushing water inlet on described housing top, described housing is made of straight barrel, last pipe cap and following pipe cap, describedly go up between pipe cap and the straight barrel, connect by flange between straight barrel and the last pipe cap, be provided with grid in the described housing, described grid is a hollow, and its side is provided with equally distributed through hole; Also be provided with inlet pipeline and outlet pipeline in the described housing, an end of described inlet pipeline communicates with described water inlet, and the other end stretches into the hollow space of described grid; One end of described outlet pipeline stretches among the described straight barrel, and the other end communicates with described delivery port; Also be provided with water-locator on described grid top, described water-locator communicates with described flushing water inlet.
According to above-mentioned filter for waste water pretreatment, the aperture of wherein said through hole is 0.8-3mm, for example preferably 0.8mm, 1.2mm or 2.0mm, and the pitch-row in adjacent hole is 1-4mm; Preferably, the aperture of described through hole is 1-1.2mm, and the pitch-row in adjacent hole is 1.5-2.5mm.
According to a kind of preferred specific embodiment of above-mentioned filter for waste water pretreatment, described grid is a truncated cone-shaped.
Preferably, described grid can be made of grid bar, stainless steel filtering net or stainless steel orifice plate, and its material can be made by stainless steel, for example adopts the SUS304 type stainless steel with good antiseptic property.
[beneficial effect]
Filter for waste water pretreatment of the present invention is simple in structure, be easy to make and safeguard that its floor space is little; 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 treatment (as film filter); Can wash grid by flushing water inlet and water-locator, to keep good strainability.

[specific embodiment]
Following embodiment is described with reference to the accompanying drawings the present invention.
Embodiment 1
Described filter for waste water pretreatment is a stainless steel structure, housing 1 high 700mm, diameter 325mm, and wherein straight barrel 3 high 388mm confine with last pipe cap 9 and 4 sealings of following pipe cap by connector and flange.Following pipe cap 4 is provided with water inlet 21 and slag-drip opening 23, and wherein water inlet 21 links to each other with inlet pipeline 13, and straight barrel 3 middle parts are provided with delivery port 22, and upward the top of pipe cap 9 is provided with flushing water inlet 24.Also be provided with handle 17 on the last pipe cap 9, make things convenient for the user to operate.
Be provided with truncated cone-shaped grid 12 at housing 1 middle part, grid 12 high 455mm, its bottom is by ring 10 and following pipe cap 4 are fixing down, and its top is connected with water-locator 16 by ring flat-plate 11.The stainless steel orifice plate that this grid adopts SUS304 type stainless steel to make, to be evenly distributed the aperture be the through hole 8 of 1.0mm to sidewall around it.
The water-locator 16 on grid 12 tops is made of with the short tube 6 that links to each other annulus 5, evenly is provided with apopore 7 below annulus 5.
At water inlet 21 and delivery port 22 places Pressure gauge is housed, during this filter operate as normal, is flowed into from water inlet 21, behind grid filtration,, flow out from filter delivery port 22 from the inboard outside that flows to of grid by filtrate body (waste water).Like this, dirt (larger particles in the waste water and fibrous matter) is dammed in the grid inboard, and along with increasing of the thing that dams, the pressure reduction of water inlet 21 and delivery port 22 also increases thereupon.When pressure reduction reaches certain numerical value, show that filter screen is blocked, can clean this moment.During cleaning, can open the valve at slag-drip opening 24 places, emptying fluid and filter residue, the dismounting flange takes out the truncated cone-shaped grid, reloads after the cleaning to get final product, and is easy to maintenance; Also can close the valve that is used to control Inlet and outlet water, open the valve and the slag-drip opening of control flushing water inlet simultaneously, carry out on-line cleaning.
Filter for waste water pretreatment of the present invention is applicable to from low concentration suspension removes fiber fines and solid impurity, floating substance, be a kind of simply, screen device efficiently.It is about 60%～80% to the clearance of the solid suspension 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 100～200mg/L, and effect is obvious.
