Description

A kind of filtering cloth filtering pool of in-depth filtration
Technical field
The present invention relates to a kind of water treatment facilities, particularly relate to a kind of filter.
Background technology
Along with urbanization and industrialized development, water requires more and more higher, especially to the amount of particulate matter contained in water, require fewer and feweri, China is from external introduction disc type rotary disc filter (pond) in recent years, this device and domestic fiber (biology) rotary disc filter (pond) and filtering cloth filtering pool all adopt filter-cloth filtering, it is large that unit occupied area is processed the water yield, reduced investment, but more than install water quality treatment poor effect (the general SS≤10mg/L of water outlet), especially former water is required to relatively strict (requiring SS≤20mg/L), otherwise easily stop up, recoil continuously, anti-shock loading is little, only be applied to the advanced treating of sewage, be that SS in < < urban wastewater treatment firm pollutant emission standard > > GB18918-2002 promotes one-level A standard from one-level B mark and promotes, the scope of application is narrow.
Summary of the invention
The invention provides a kind of filtering cloth filtering pool of in-depth filtration, the problem that the present invention solves and existingly requires raw water quality high (requiring SS≤20mg/L) at rotary disc filter (pond) and filtering cloth filtering pool, easily stops up, effluent quality is not good, anti-shock loading is little, use occasion is narrow.This device adopts the design of multiple tracks filter-cloth filtering, per pass filter-cloth filtering precision is different, the impurity that in former water, particle is larger is first by filtering the thicker filter cloth filter element filtering of void ratio, the impurity that particle diameter little Yu filters space will enter second filtration through filter cloth filter core, the filter cloth filter core void ratio first filter cloth filter core space that second filters is little, to carry out essence filters, through two roads filtrations, reaching particulate matter in water has incited somebody to action seldom, in water, particulate matter is better than the water standard of industrial water supply, reach running water standard, if water quality requirement is higher, according to above principle, increase San road or Multi-channel filtering more.
For addressing the above problem, the present invention adopts following technical scheme: water inlet pipe valve (2) is installed on water inlet pipe (1), be used for controlling whether this filter intakes and the number of inflow, former water is entered into water rectification canal (3) and is reduced flow velocity by water inlet pipe (1), reduce impact load, in water inlet rectification canal (3), be provided with into water regulating weir (6), regulate the water level height with other operation that is in parallel, water inlet rectification canal (3) pool wall has spout hole (5), when the water yield increases suddenly a lot of and this filter and cannot process so big yield, former water will overflow a part from spout hole (5), water inlet rectification canal has into water rectification canal blow-down pipe (24) and feed water flow canal atmospheric valve (25), easy access is used,
Former water climbs over the central authorities that enter filter body (4) length direction into water regulating weir (6), first the impurity that particle is larger filter by filtering the thicker filter cloth filter core (8) of void ratio, a part precipitates larger granule foreign Direct precipitation at the bottom of pond, the impurity that particle diameter little Yu filters space will enter second filtration through filter cloth filter core (8), filter cloth filter core (8) void ratio first filter cloth filter core (8) space that second filters is little, to carry out essence filters, through two roads filtrations, reaching particulate matter in water has incited somebody to action seldom, if water quality requirement is higher, according to above principle, increase San road and live more Multi-channel filtering, clear water after filtration climbs over water outlet regulating weir (14) inflow effluent collection canal (15) and gathers, passing through outlet pipe (17) and outlet pipe valve (16) flows out again, filter cloth filter core (8) is arranged on filter core bracing frame (9) by filter cloth, filter cloth filter core (8) is arranged on the filter core fixed mount (7) sealing with pool wall, form Modular assembled, easy for installation, safeguard simple, be out of shape little,
The both sides of every one filter cloth filter core (8) are all provided with water level detection gauge, when the water level of filter cloth filter core (8) influent side and the water-head of water outlet side surpass setting value, show that the impurity that filter cloth filter core (8) adheres to is saturated, require to clean this filter core, by automatic control cabinet, will start the back suction sucking pump of anti-aspirator (10), anti-aspirator sucker (20) is by the impurity suction of filter cloth filter core (8), impurity after suction enters in the dirt trap of anti-aspirator (10) by anti-aspirator suction tube (13), the lifting device that passes through again anti-aspirator (10) promotes or certainly spills out back suction and inhales device blow-off pipe (11), in anti-aspiration procedure, anti-aspirator (10) will walk back and forth on the anti-aspirator guide rail (12) along device length direction,
The granule foreign being deposited at the bottom of pond will be got rid of in time, this device is provided with by blowdown and is in charge of (18) at the influent side of each filter cloth filter core (8), by blowdown, be in charge of support (19) apart from certain altitude at the bottom of pond, crossing blowdown is in charge of the downside of (18) and has blowdown to be in charge of soil pick-up hole (21), while wanting blowdown and emptying, first open blowdown and divide tube valve (22), at the bottom of the pond of appropriate section, the impurity of precipitation is in charge of soil pick-up hole (21) suction by gravity from blowdown, is in charge of (18) outflow enters blowdown main (23) through blowdown.
