Abstract
The utility model discloses a grate-type aerator of a submerged flat membrane component of a membrane bioreactor, which is characterized in that the lower portion of each single flat membrane element (1) is provided with a plurality of flat-shaped aerator pipes (3) which are parallel to each other and arranged at intervals, one end of each flat-shaped aerator pipe is commonly connected to an air intake and discharge pipe (4), the other end of each flat-shaped aerator pipe is commonly connected to an air main pipe (2), and each single flat membrane element (1) is positioned right above the central line of each clearance between the flat-shaped aerator pipes (3) which are respectively provided with a row or multiple rows of aerator holes (5) positioned upwards. The grate-type aerator effectively overcomes shortcomings of uneven aeration, poor scour of membrane surfaces and the like caused by the fact that multiple groups of membrane elements use a same aerator pipe for aeration, prevents the membrane elements from being clogged by dirty sludge and prevents membrane pollution without changing flow directions of working water of an original submerged flat membrane element.
Description
Technical field
The utility model belongs to the Membrane Bioreactor for Wastewater Treatment field of wastewater, specifically, is a kind of grate formula aerator of membrane bioreactor submerged flat membrane assembly.
Background technology
In recent years, membrane bioreactor is rapidly developed both at home and abroad, because active sludge biological is quite abundant in the membrane bioreactor, reactor has decarburization denitrogenation dephosphorizing function, and excess sludge is few, facility compact, floor space is few, and can modular design, operational management is convenient, so obtained large-scale application.The aeration case is established in the submerged flat membrane bio-reactor membrane module below that existing market provides, and establishes aeration tube (seeing accompanying drawing one) in the aeration case.Air is discharged in aeration tube continuously during work, forms bubble the film surface is cleaned, and makes active sludge be difficult at the film surface deposition, carries out thereby the assurance membrane filtration is stable.But because the aeration tube radical of present membrane module is much smaller than the membrane element number of packages, 50～200 membrane elements combinations of a general employing of membrane module, and corresponding aeration tube has only 2～8, therefore often appearance is not good away from the film surface cleaning that aeration tube vertically washes away the position, when serious even two active sludge latch up phenomenons between the membrane element occur, influence the continuous operation of membrane bioreactor.
Summary of the invention
The purpose of this utility model then is at present above-mentioned the deficiencies in the prior art, provide a kind of aeration evenly, to the grate formula aerator of the good membrane bioreactor submerged flat membrane assembly of face scouring effect.
The technical solution adopted in the utility model is as follows:
A kind of grate formula aerator of membrane bioreactor submerged flat membrane assembly, include multi-disc monolithic flat membrane component, it is characterized in that below each monolithic flat membrane component, being provided with many parallel and flat aeration tubes that be provided with at interval, many flat aeration tube one ends are connected to air jointly and introduce delivery line, their the other end is connected to the female pipe of air jointly, each monolithic flat membrane component is directly over the medullary ray in gap between each root flat aeration tube, and the spacing distance between adjacent two flat aeration tubes all has a row or multi-row position solarization air cap up greater than the thickness of monolithic flat membrane component on each root flat aeration tube.
Wherein, female pipe of the air that described flat aeration tube and two ends thereof connect and air are introduced delivery line and are adopted stainless steel to make, and improve their intensity, are convenient to adopt thin-walled tube to make.
The female pipe of described air is introduced delivery line with air and is be arranged in parallel, and the distance between them is greater than the width of monolithic flat membrane component.
The beneficial effects of the utility model have:
The aeration inequality of effectively having avoided many groups membrane element to adopt same aeration tube aeration to cause, face is washed away defectives such as not good, prevent dirt sludge blockage membrane element, prevent that film from polluting, and control stainless steel air is introduced on the delivery line valve opening or is closed and can carry out the gas recoil to the flat aeration tube, dirt in the cleaning pipe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the flat aeration tube 3 that the utility model is positioned at each monolithic flat membrane component 1 below is provided with many, its quantity is than more than 1 one of monolithic flat membrane components, their many parallel and settings at interval, and the spacing distance between adjacent two flat aeration tubes 3 is greater than the thickness of monolithic flat membrane component 1, each monolithic flat membrane component 1 can make flat aeration tube 3 even to every monolithic flat membrane component 1 face scouring effect when aeration directly over the medullary ray in gap between each root flat aeration tube 3 like this.Above-mentioned many flat aeration tube 3 one ends are connected to air jointly and introduce delivery line 4, and their the other end is connected to the female pipe 2 of air jointly, and the female pipe 2 of air is introduced delivery line 4 with air and be arranged in parallel, and the distance between them is greater than the width of monolithic flat membrane component 1.On each root flat aeration tube 3, all have a row or multi-row position solarization air cap 5 up.Female pipe 2 of the air that flat aeration tube 3 and two ends thereof connect and air are introduced delivery line 4 and can be adopted stainless steel to make, and the intensity height can adopt thin-walled tube to make like this.
The aeration rate of every membrane element of the utility model is 1.5～2NL/min, with stainless steel flat aeration tube overcurrent flow velocity≤3m/s, determines the overflow section of stainless steel flat aeration tube.It is (1.5～2NL/minn) * (n+1) that female pipe of stainless steel air and stainless steel air are introduced delivery line overcurrent air capacity, introduce delivery line overcurrent flow velocity≤6m/s with female pipe of stainless steel air and stainless steel air, determine that stainless steel air mother manages and the stainless steel air is introduced the delivery line overflow section.
Other undeclared part that the utility model relates to is same as the prior art.
