Abstract
The invention discloses an air-flotation aeration-type biofilter treatment system. The biofilter treatment system mainly comprises three parts, namely mainly comprises a pressurized dissolved air flotation aeration system, a biofilter system and a sludge scraping system. An aeration system of the biofilter is replaced by the pressurized dissolved air flotation aeration system. Water distribution pipes are replaced by air-dissolved water distribution pipes and the sludge scraping system is added. The biofilter treatment system is capable of increasing the aeration efficiency at the same time of reducing inflow suspension and a little amount of oil, and has characteristics of low backflushing frequency, large dissolved oxygen amount, and the like. The biofilter treatment system solves technical problems of high requirements for the inflow suspension, low aeration efficiency, and the like of biofilters at present. The biofilter treatment system is used for the field of sewage treatment, and can replace the aeration biofilters at present and pretreatment systems used for reducing the suspension of the aeration biofilters at present.
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 is compared with conventional activated sludge process, has microbial film and easily cultivates, and microbial profile is reasonable, the residence time is short, processing power is strong, and energy consumption is low, and nitrification efficiency is high, sludge yield is few, treating processes free from extraneous odour produces, and can not produce sludge bulking, and floor space is little, 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 requirement SS≤100mg/L to water inlet SS, best SS≤60mg/L), therefore to water inlet, need to carry out pre-treatment, meanwhile, once SS is too high, will cause filtrate dirty stifled, filtrate inside may form channel, and backwash continually, not only needs to expend a large amount of backwashing waters, and can affect the microbial film 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.
An air supporting aeration type biological filter chamber treatment system, comprises aerating system and bacteria filter system, and wherein, described aerating system is pressurized dissolved air flotation aerating system, comprises air compressor, dissolving and dissolved air release; The water distributor of described bacteria filter system is the dissolved air water water distributor of lifeless matter filter tank filler; Described air supporting aeration type biological filter chamber treatment system also comprises the mud system of scraping that is positioned at described bacteria filter system top, comprises mud scraper and mud drainage slot; Described pressurized dissolved air flotation aerating system is connected by described dissolved air release with the dissolved air water water distributor of described bacteria filter system.
On described dissolving, be respectively equipped with for passing into the water inlet pipe for the treatment of sewage and for passing into the inlet pipe of gas.
Described bacteria filter system also comprises filter plate, is covered with bio-filter stuffing on filter plate,,, bottom, filter tank is provided with bottom discharge pipeline, is also provided with back flushing water pipe and back flushing tracheae, and top, filter tank is provided with backwash water water shoot.
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 distribute is mainly determined by shape and the size of biological filter, independent biological filter 1-5 root, and preferred 4-5 root, it is evenly object that water distribution is mainly take in distribution.
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 suspended substance and a small amount of oil in water more, improve biological filter influent quality, reduce the cleaning frequency of biological filter, can improve aeration efficiency again, improve more the content of oxygen in water, improve biological filter to organic removal effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that legend is overlooked in biological filter dissolved air water water distributor distribution.
Embodiment
As described in Figure 1, air supporting aeration type bacteria filter system of the present invention, mainly comprises pressurized dissolved air flotation aerating system 20, bacteria filter system 30 and scrapes mud system 40.Pressurized dissolved air flotation aerating system 20, mainly comprises air compressor 1, dissolving 2, and dissolved air release 3 etc.Pending sewage and gas enter dissolving 2 by water inlet pipe 8 and 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 enters the dissolved air water water distributor 4 of biological filter by dissolved air release 3, molten gas in dissolved air water is discharged in dissolved air water upwards flows, the suspended substance carrying in dissolved air water floats to above the dissolved air water liquid level of bacteria filter system 30, the sewage that contains a large amount of dissolved oxygens flows to behind bacteria filter system 30 tops along vessel water water distributor, again to by bio-filter stuffing 7, from bacteria filter system 30 bottom discharge pipelines 10, discharge.Suspended substance on liquid level is collected mud drainage slot 6 by mud scraper 5 and is eliminated.The body bottom, pond of bacteria filter system 30 is provided with back flushing water inlet pipe 11 and back flushing inlet pipe 12, and top is provided with back flushing water shoot 13.
The quantity of dissolved air water filling pipe 4 of the present invention and distribute mainly determined by shape and the size of biological filter, as shown in Figure 2, general each independent biological filter 1-5 root, preferred 4-5 root, it is evenly object that water distribution is mainly take in distribution.
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.
Lifeless matter 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 biological filter and form.
The aerating system of biological filter 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.Pressurized dissolved air flotation aerating system of the present invention can either be removed suspended substance and a small amount of oil in water more, improve biological filter influent quality, reduce the cleaning frequency of biological filter, can improve aeration efficiency again, improve more the content of oxygen in water, improve biological filter to organic removal effect.
