Description
Technical field
The present invention relates to a kind of filler unit of WWT, and the method for manufacture of the porous active filling block in this device.
Background technology
Serious day by day along with China's water pollution situation, the exploitation of technology of waste water control more and more causes people's attention.The input of biologic packing material is a kind of common technique means of present water pollution control; The general material of passing through to throw in different shapes such as natural fiber, synthetic material is in water body; Through the natural membrane effect of the mikrobe in the water body at filling surface; Form microbial film to reach the effect that purifies water; Like application number is that 201010618440.5 patent of invention promptly adopts this method, but utilizes in the natural membrane process that the matrix of various materials carries out, because the shortage of mikrobe provenance, the competition effect between mikrobe etc. in the water body at above-mentioned filler; Often can't carry out the advantage enrichment, to reach the purpose of specific pollutants in the quick removal water body to the mikrobe of some specific pollutants (like ammonia nitrogen, tensio-active agent, sulfide etc.) in the water body of can degrading.Deficiency to existing natural membrane process; People begin one's study combining of filler and microbial immobilized technology; Though like application number is that 200910192555.X, 200910236439.3 patent have all been carried out immobilization to extraordinary mikrobe; But application number is the patent of 200910192555.X carries out embedding through materials such as cement, Wingdales to mikrobe; Application number be 200910236439.3 patent then utilize rubber as matrix through gel immobilized mikrobe, can't guarantee all in the filler making method of above-mentioned two patents that the contact area of mikrobe and water body is enough big; Grant number is that the patent of CN 101225379B is then only carried out immobilization through agar or gelatin to mikrobe, the practical experience surface, and the immobilization material intensity that this method obtains is too low, in water treatment procedure, is difficult to obtain actual application.
Summary of the invention
The present invention overcomes the deficiency of carrier performance in the existing sewage treatment process; Provide a kind of specific pollutants is purified the hole inside that dominant bacteria is incorporated into porous matrix; And through the certain structure device it is created and to be easy to the filler unit that practice of construction is used; Have advantages such as efficient, stable thereby reach whole device, the method for manufacture of the porous active filling block in the filler unit of the present invention in addition also is simple, a science very.
Realize above-mentioned purpose; The present invention adopts following technical scheme; A kind of filler unit that is used for WWT; It is characterized in that: include ball float, mesh bag, porous active filling block and be used for the base of filler unit submerged, said porous active filling block is contained among the mesh bag, and said ball float places the two ends of mesh bag with base and is fixedly connected with mesh bag.
Through adopting such scheme, the filler unit that makes can make filler unit keep upright state after sinking to water body, guarantees that filler unit and water body have good exchange interface; According to the depth and the water pollution degree of actual water body, adjust the length of single filler unit mesh bag and the quantity and the kind of interior charge in addition, in practical engineering application, have advantages such as flexible, convenient.
The further technical scheme of filler unit of the present invention is: said ball float is processed by the plastics with good buoyancy or rubber or foam; The maximum diameter of said porous active filling block is greater than the mesh maximum diameter of mesh bag; Said base is processed by cement block or stone; Ball float on the said mesh bag and porous active filling block constitute a filler unit, on the said base one or more filler units can be set.
The technical scheme of the method for manufacture of the porous active filling block in the filler unit of the present invention is: choose have certain intensity the porous material piece with corrosion resistant function as matrix; Matrix is formed gel with the mikrobe entrapping method on its side face and inside, thereby and the mikrobe that in the process that gel solidifies, will have a specific pollutants degradation function be fixed in the hole of porous material piece matrix and obtain the porous active filling block.
The effect of above-mentioned method of manufacture technical scheme is: 1, utilize the embedded immobilization technology that the target contaminant dominant bacteria of degrading is embedded in wherein; Form compound embedded immobilization porous active filler; Not only can overcome the shortcoming of traditional embedding immobilization particle insufficient strength; And can utilize the huge specific surface area of porous material and the powerful detergency ability of the mikrobe that is fixed, realize the target contaminant in the water body is removed fast.2, through embedded immobilization technology, mikrobe is fixed in the hole of porous material, thereby can realizes starting fast the effect of filler detergency ability, overcome the conventional filler device and utilized natural extension membrane interaction and cause long difficult problem start time.3, through the embedded immobilization technology; Characteristic contaminant degradation mikrobe is fixed in the hole of porous material; Such as nitrifier, tensio-active agent degradation bacteria, sulfide degradation bacteria etc.; Keep the superiority of characteristic contaminant degradation bacterium in the filling surface microecosystem through immobilization material, avoided in natural extension membrane interaction process, characteristic contaminant degradation mikrobe is owing to be in a disadvantageous position in competition with other mikrobes; Be difficult to the stable existence in biofilm surface, thereby make the microbial film of conventional filler be difficult to realize effective removal some characteristic pollutent.
The further technical scheme of the method for manufacture of porous active filling block is: the preferred sponge block of described matrix or volcanics or corallite; Said mikrobe entrapping method preferably polyethylene alcohol entrapping method or calcium alginate embedded method, one or more in the said preferred nitrifier of mikrobe with specific pollutants degradation function, aerobic bacteria, denitrifying bacteria, the sulfide bacterium for degrading.
Below in conjunction with accompanying drawing the present invention is further described.
Description of drawings
Fig. 1 is the structural representation of the filler unit of the embodiment of the invention.
Specific embodiment
As shown in Figure 1; The filler unit of the embodiment of the invention is made up of ball float 1, mesh bag 2, change porous active filling block 3 and base 5; Wherein, ball float 1 can be that the material that plastics, rubber, foam etc. have good buoyancy is processed, and its effect is to make filler unit after sinking to water body; Can make filler unit keep upright state, guarantee that filler unit and water body have good exchange interface; The maximum diameter of said porous active filling block 3 is greater than the mesh maximum diameter of mesh bag 2; Its effect is that porous active filling block 3 is played package action; To improve the accessibility that it is used; Base 5 can be made up of heavy material such as cement block, stones, when throwing in enforcement, plays the effect that sinks to the bottom, and filler unit is fixed on water bottom.Porous active filling block 3 quantity of throwing in fixed filler unit quantity, the single mesh bag 2 on the size of the size of base 5, mesh bag 2 and length, the single base 5 in addition, etc. parameter can be according to engineering construction the time, the degree of depth of water body, water quality situation, throw in practical situation such as mechanical means and specifically adjust.
