Background technology
The crisis of facing mankind water has been undisputable fact, and China adds the input to urban infrastructure construction and environment protection, strengthening comprehensive environmental improvement, thus gross contamination emission is effectively controlled, and some areas and city environmental quality make moderate progress.But environmentally monitoring result statistical study, China's water pollutions situation is still very severe, and every gross contamination emission is very large, and pollution level is still in quite high level.
In the past few years, the industry ability of sewage treatment industry there occurs the change of matter, the change of this matter primarily of two aspects, one be the number of sewage work in quick increase, two is that overall processing power is increasing rapidly.About have 3000 Duo Zuo sewage works, industrial wastewater discharge amount up to standard 2011 is 54,000,000,000 tons, within 2012, can break through 76,000,000,000 tons.The change of amount also result in the change of matter to a certain extent.
But a lot of sewage disposal device has significant limitation now, if raising quality of sewage disposal, need by improving sewage adding consistency, increasing filter material replacement number of times or carry out the measures such as hay tank structure of modification, the expense so just causing sewage disposal is higher, is unfavorable for the development of sewage treatment industry.Existing sewage disposal device to the interception of small particle size suspended substance and limited sorption capacity, reinjected water suspended substance and median particle size qualified rate lower.
Utility model content
The purpose of this utility model is to provide one greatly to improve quality of sewage disposal, increases the interception to small particle size suspended substance and absorption, and the sewage processing filtering device based on metallic membrane that use cost is lower.
The utility model is achieved through the following technical solutions: a kind of sewage processing filtering device based on metallic membrane, comprises body, and described bodies top is cleaning liquid inlet, and bottom is sewage draining exit; Body upper part is also provided with water-in, and bottom is provided with water outlet; Pretreatment layer and metal membrane filter layer is provided with from top to bottom successively in body interior.Concrete sewage treatment process is, when carrying out sewage disposal, closes cleaning liquid inlet and sewage draining exit, sewage passes into pretreatment layer from the water-in of body, pretreatment layer has stronger adsorptivity, and after multi-layer porous filtering layer, the oil content in sewage and bulk impurity are removed step by step.
Flow through metal membrane filter layer downwards again through pretreated sewage, after the metal membrane filter post in metal membrane filter layer filters, remove small granular suspended matters further, the sewage of after purification flow out from the water outlet of body lower part.
When this filtration unit is cleared up, close water-in and water outlet, scavenging solution is poured into by the scavenging solution import of bodies top, scavenging solution washes away pretreatment layer and metal membrane filter layer, the impurity filtered washes out, then discharged by the sewage draining exit of bottom, realize the regeneration of pretreatment layer and metal membrane filter layer, ensure that it can have higher filter activity.
In order to realize the utility model better, further, described pretreatment layer comprises quartz sand layer, ceramic rock layers, silicon carbide layer and pebbles layer from top to bottom successively, and the antirust plate by being provided with via-hole array between each layer is separated.
In order to realize the utility model better, further, described metal membrane filter layer is provided with at least two metal membrane filter posts arranged in parallel.
In order to realize the utility model better, further, described metal membrane filter post quantity is three, and the direction of metal membrane filter post is vertical direction.
In order to realize the utility model better, further, described metal membrane filter post is titanium metal film Filter column.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) sewage filter device based on metallic membrane described in the utility model, can increase the interception to small particle size suspended substance and absorption, improve quality of sewage disposal, reduce sewage disposal expense, thus reduces the cost of sewage disposal;
(2) the utility model by setting up pretreatment layer on metal membrane filter layer, thus good pre-treatment has been carried out to the sewage entering metal membrane filter, avoid metal film filter and filter greater particle size impurity, extend the work-ing life of metal film filter, also improve quality of sewage disposal simultaneously;
(3) what the metal membrane filter post in the utility model used is titanium metal film Filter column, greatly promotes the filter effect to sewage, and durable in use, in a disguised form reduces cost of sewage disposal.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features of the present invention, object and advantage will change to obviously:
Fig. 1 is structural representation of the present utility model.
Wherein: 1-cleaning liquid inlet, 2-water-in, 3-quartz sand layer, 4-ceramic rock layers, 5-silicon carbide layer, 6-pebbles layer, 7-metal membrane filter post, 8-water outlet, 9-sewage draining exit.
Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
Embodiment:
The primary structure of the present embodiment, as shown in Figure 1, comprises body, and described bodies top is cleaning liquid inlet 1, and bottom is sewage draining exit 9; Body upper part is also provided with water-in 2, and bottom is provided with water outlet 8; Pretreatment layer and metal membrane filter layer is provided with from top to bottom successively in body interior.
