Abstract
A kind of air supporting aeration type biological filter chamber treatment system, mainly comprises three parts, pressurized dissolved air flotation aerating system, bacteria filter system and scrape mud system. The aerating system of biofilter of the present invention is substituted by pressurized dissolved air flotation aerating system, and water distributor is replaced by dissolved air water water distributor, and increases the mud system of scraping. This system can further reduce water inlet suspension and a small amount of oily in, improve aeration efficiency, have that backwash frequency is low, dissolved oxygen high, solve the technical problems such as existing biofilter is high to the requirement of water inlet suspension, and aeration efficiency is low. The present invention, for sewage treatment area, can replace the pretreatment system of existing BAF and reduction suspension thereof.<!--1-->
Description
Technical field
The present invention relates to a kind of biological filter chamber treatment system, relate more specifically to a kind of air supporting aeration type biological filter chamber treatment system.
Background technology
BAF, compared with conventional activated sludge process, has biomembrane and easily cultivates, and microbial profile is reasonable, the time of stayingShort, disposal ability is strong, and energy consumption is low, and nitrification efficiency is high, and sludge yield is few, and processing procedure free from extraneous odour produces, and can not produce mudExpand, floor space is little, and water outlet does not need the advantages such as second pond are set separately, thereby is taken seriously in sewage disposal.
But it requires strict (General Requirements SS≤100mg/L, preferably SS≤60mg/L) to water inlet SS, therefore water inlet is neededCarry out pretreatment, meanwhile, once SS is too high, will cause filtrate dirty stifled, filtrate inside may form channel, and continuallyBackwash, not only needs to expend a large amount of backwashing waters, and can affect the biomembrane on filtrate, and then affect treatment effect.
Summary of the invention
In order to address the above problem, the invention provides a kind of air supporting aeration type biological filter chamber treatment system.
A kind of air supporting aeration type biological filter chamber treatment system, comprises aerating system and bacteria filter system, and wherein, described aeration isSystem, for pressurized dissolved air flotation aerating system, comprises air compressor, dissolving and dissolved air release; Described bacteria filter systemWater distributor is the dissolved air water water distributor of inanimate object filter tank filler; Described air supporting aeration type biological filter chamber treatment system also comprises and is positioned at instituteThe mud system of scraping of stating bacteria filter system top, comprises mud scraper and mud drainage slot; Described pressurized dissolved air flotation aerating system with described inThe dissolved air water water distributor of bacteria filter system connects by described dissolved air release.
On described dissolving, be respectively equipped with water inlet pipe for passing into treatment sewage and for passing into the air inlet pipe of gas.
Described bacteria filter system also comprises filter plate, is covered with bio-filter stuffing on filter plate, and bottom, filter tank is provided with bottom discharge pipeLine, is also provided with backwash water pipe and backwash tracheae, and top, filter tank is provided with backwash water drainpipe.
The described mud system of scraping is that peripheral-traction formula is scraped mud system or chain type is scraped mud system.
The quantity of dissolved air water water distributor of the present invention and the main shape by biofilter that distributes are determined with size, independent biofilter1-5 root, preferably 4-5 root, distributes mainly taking water distribution evenly as object.
Dissolved air water water distributor of the present invention can adopt diameter pipe unanimous between the higher and lower levels, also can adopt the up big and down small pipe of diameter.
The invention has the beneficial effects as follows: air supporting aerating system can either be removed suspension and a small amount of oil in water more, improvesBiofilter influent quality, reduces the cleaning frequency of biofilter, can improve again aeration efficiency, improves more in water moltenSeparate the content of oxygen, improve biofilter to organic removal effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that legend is overlooked in biofilter dissolved air water water distributor distribution.
Detailed description of the invention
As described in Figure 1, air supporting aeration type bacteria filter system of the present invention, mainly comprise pressurized dissolved air flotation aerating system 20,Bacteria filter system 30 and scrape mud system 40. Pressurized dissolved air flotation aerating system 20, mainly comprises air compressor 1, molten gasTank 2, and dissolved air release 3 etc. Pending sewage and gas enter dissolving 2 by water inlet pipe 8 and air inlet pipe 9 respectively,In dissolving 2, maintain certain pressure, make to dissolve in a large amount of air and form dissolved air water in water, dissolved air water passes through dissolved air release3 enter the dissolved air water water distributor 4 of biofilter, and the molten gas in dissolved air water is discharged in dissolved air water upwards flows, and carries molten gasSuspension in water floats to the dissolved air water liquid level top of bacteria filter system 30, and the sewage that contains a large amount of dissolved oxygens is along dissolved air waterWater distributor flows to behind bacteria filter system 30 tops, then under to by bio-filter stuffing 7, from bacteria filter system 30 bottomsFlowing line 10 is discharged. Suspension on liquid level is collected mud drainage slot 6 by mud scraper 5 and is eliminated. Bacteria filter system 30Pond body bottom be provided with backwash water inlet pipe 11 and backwash air inlet pipe 12, top is provided with backwash drainpipe 13.
The quantity of dissolved air water filling pipe 4 of the present invention and distributing mainly determined by shape and the size of biofilter, as shown in Figure 2,General each independent biofilter 1-5 root, preferably 4-5 root, distributes mainly taking water distribution evenly as object.
Dissolved air water water distributor 4 of the present invention can adopt diameter pipe unanimous between the higher and lower levels, also can adopt the up big and down small pipe of diameter.
Inanimate object filter tank filler in dissolved air water water distributor 4 of the present invention.
Form of scraping mud system 40 of the present invention can convert according to the shape of biofilter and form.
The aerating system of biofilter of the present invention is substituted by pressurized dissolved air flotation aerating system, and water distributor is by dissolved air water water distributorReplace, and increase the mud system of scraping. Pressurized dissolved air flotation aerating system of the present invention can either be removed the suspension in water moreWith a small amount of oil, improve biofilter influent quality, reduce the cleaning frequency of biofilter, can improve again aeration efficiency, largerDegree improves the content of oxygen in water, improves biofilter to organic removal effect.
